Ramblings from the Pingdom team about the Internet and web tech

Posted in Main on April 8th, 2008 by Pingdom

Nowadays we are used to having hundreds of gigabytes of storage capacity in our computers. Even tiny MP3players and other handheld devices usually have several gigabytes of storage. This was pure science fictiononly a few decades ago. For example, the first hard disk drive to have gigabyte capacity was as big as arefrigerator, and that was in 1980. Not so long ago!

Pingdom stores a lot of monitoring data every single day, and considering how much we take todays storagecapacity for granted, its interesting to look back and get things in perspective. Here is a look back at someinteresting storage devices from the early computer era.

The Selectron tube

The Selectron tube had a capacity of 256 to 4096 bits (32 to 512 bytes). The 4096-bit Selectron was 10 incheslong and 3 inches wide. Originally developed in 1946, the memory storage device proved expensive andsuffered from production problems, so it never became a success.

Punch cards

Early computers often used punch cards for input both of programs and data. Punch cards were in commonuse until the mid-1970s. It should be noted that the use of punch cards predates computers. They were usedas early as 1725 in the textile industry (for controlling mechanized textile looms).

Punched tape

Same as with punch cards, punched tape was originally pioneered by the textile industry for use withmechanized looms. For computers, punch tape could be used for data input but also as a medium to outputdata. Each row on the tape represented one character.

Above: 8-level punch tape (8 holes per row).

Magnetic drum memory

Invented all the way back in 1932 (in Austria), it was widely used in the 1950s and 60s as the main workingmemory of computers. In the mid-1950s, magnetic drum memory had a capacity of around 10 kB.

the IBM 650 computer. It had 40 tracks, 10 kB of storage space, and spun at 12,500 revolutions per minute.

The hard disk drive

The first hard disk drive was the IBM Model 350 Disk File that came with the IBM 305 RAMAC computer in1956. It had 50 24-inch discs with a total storage capacity of 5 million characters (just under 5 MB).

Above:IBM Model 350, the first-ever hard disk drive.

The first hard drive to have more than 1 GB in capacity was the IBM 3380 in 1980 (it could store 2.52 GB). Itwas the size of a refrigerator, weighed 550 pounds (250 kg), and the price when it was introduced rangedfrom $81,000 to $142,400.

capacity hard disk drive.

The Laserdisc

We mention it here mainly because it was the precursor to the CD-ROM and other optical storage solutions. Itwas mainly used for movies. The first commercially available laserdisc system was available on the marketlate in 1978 (then called Laser Videodisc and the more funkily branded DiscoVision) and were 11.81 inches(30 cm) in diameter. The discs could have up to 60 minutes of audio/video on each side. The first laserdiscshad entirely analog content. The basic technology behind laserdiscs was invented all the way back in 1958.

Above left: A Laserdisc next to a regular DVD.Above right: Another Laserdisc.

The floppy disc

The diskette, or floppy disk (named so because they were flexible), was invented by IBM and in common usefrom the mid-1970s to the late 1990s. The first floppy disks were 8 inches, and later in came 5.25 and3.5-inch formats. The first floppy disk, introduced in 1971, had a capacity of 79.7 kB, and was read-only. Aread-write version came a year later.

convenience of easily removable storage media.

Magnetic tape

Magnetic tape was first used for data storage in 1951. The tape device was called UNISERVO and was themain I/O device on the UNIVAC I computer. The effective transfer rate for the UNISERVO was about 7,200characters per second. The tapes were metal and 1200 feet long (365 meters) and therefore very heavy.

Above left: The row of tape drives for the UNIVAC I computer.Above right: The IBM 3410 Magnetic TapeSubsystem, introduced in 1971.

And of course, we cant mention magnetic tape without also mentioning the standard compact cassette, whichwas a popular way of data storage for personal computers in the late 70s and 80s. Typical data rates forcompact cassettes were 2,000 bit/s. You could store about 660 kB per side on a 90-minute tape.

And, by the way, the 1st computer I worked with (long before I owned one) had a large operator's

console with 16 KB (yes I said KB) of memory, and card storage. And before that I worked in an

auto plant where the "Tab Room" featured a wired-board programmed IBM computer that did an

amazing 6 FLOPs/sec.!!

Now I carry a shirt-pocket internet-able device with 64 GB, and falling behind the curve every

day.

There was also the punch-card Jacquard textile looms in the 19th century that probly inspiredHollerith. And does anyone remember "Otsego Project", which I recall as an experimental large

scale drum storage machine by old AT&T.

kitty112233

That's MY H|W done then!!!! Thank-You very much for creating this website!!!!!

Frank

I remember my first program, on Hollerith cards. My first computer had 64 MB of memory. I

thought I was living in the fast lane. Today, life really is fast and getting faster. My children know

more about computers than most graduates did when I finished. Don't ask when, I won't tell.

welson

Thanks to these Computer architectures who continued this cycle of memory devices improvement

and now a days don't having any problem while carrying 500Gb hard disk in our pocket.

Tom Shipp

I used everyone of these in my career starting in the early 1960's.

Nick

I had that exact same Commodore cassette player for my Vic 20, you just brought back memories

of an innocent childhood 25 years ago. Cheers.

Sky

Interesting. First, I could never figure out why anyone would want to spend so much money to

build such a big harddisk with only 5MB of space! Though thanks to IBM and all the genius that

keep working on this, and we get to enjoy our small size laptop with Gigabytes of spaces. =)

It really is amazing to see how fast technology develops. I remember years ago when a 64Mb

HDD was the latest tech. Now you can get over 1Tb. Simply incredible.

Fajas

Oh boy ., I am old. I remember punch cards while in college.

mhendis

Way to make me feel old, guys. I actually used [i.e. programmed with] both punch cards and paper

tape. It felt high tech at the time.

Elaine

Hey, no one has mentioned the other storage medium that was widely used by consumers

beginning around 1900 -- Piano rolls. These were similar to punched tape, but were large paper

rolls that each contained a tune. The mechanism in the piano used air pressure through the holes in

the paper that caused the wires inside to be struck by the felt hammers to produce the tune.

psihometrika

actually on some systems it would play out loud when loading a cassette, most systems used the

output of the cassette player which disabled the internal speaker, i had a ti/99 that would play the

cassettes while loading them.

Commodore released a new version of the casette unit, called Load-It! if I recall correctly, with a

knob to adjust the head (and a led meter showing the level of signal), instead of just hole for a

screw driver because of the unreliability of loading non-pirated software. I never had a Load-It

Datasette, so loading games was a pain in the backside.

I recall that drum memory was also used for primary data storage (RAM). It was used as random

access memory in early computers. I think the Jargon file has an anecdote about the first

programmer who optimized his code to the spin rate of the drum so that the next instruction would

be read just-in-time, without delay (a whole revolution of the drum, which was a considerable

amount of time then). On the Commodore 64 Datasette many confuse the sound produced through

the sound chip when loading some programs using a tape turbo (data compression program to

reduce the time to load the main program), which some commercial game compilations used.

Other home computer casette units may have produced sound, but on the Commodore 64 it was

purely an annoying cosmetic touch by the programmer of the turbo loader (together with a flashing

and/or striped screen). The reason for the flashing screen was purely practical though, as most

commercial tapes were recorded at such a low level (to make it difficult to just dub the tape to

thwart piracy) that you had to adjust the datasette read head with a screw driver to be able to load

the damn game; if the screen stopped flashing while loading you knew you had to adjust the head

and try again.

Wm Franklin

Other forms of storage which could be added: The 12" floppy disk - 1Mb, hard-shell case, used

on late-60s, early 70 IBM machines, among them System 360, Model 44 DECtape - used in a

number of DEC (Digital Equipment Corp. machines in the PDP series. This was a 1" reel, about

3-4" in diamter, held 350 Kb (if I remember correctly), and could be read/written in either

direction. Its main claim to fame was that you could unspool some tape, wad it up in your hand,

straighten it out (leaving folds & wrinkles), respool it, and read it without errors. Sort of like a

tape-era USB key. The IBM 2311 (7 platter) & 2314 (14 platter) removable disk pack withcompletely unshielded platters, about 14" in diameter. Used in IBM System/360 and /370

mainframes as primary storage.

Cambronze

A couple of interesting thoughts partially relating to memory and older computer systems. DO

NOT RUN with a box of punch cards. If I was in a hurry to get my time on the computer, I always

ended up tripping and spilling the lot. They then needed to be reordered and my slot was lost.

Sound from a C64 only when listening on an ordinary cassette player OR when correctly set,

typed and spaced a friend had silent night on a dot matrix printer. I still have Microsoft Pascal

Compiler manual and disks in original plastic box. My first introduction to Basic programing was

on the states first mainframe, accidentally created an infinite loop. Put it out of commission for

about an hour, while we tried to remove it. Never saw bureaucrats move so fast!

cassette's while loading them.

Zenith

That was a blast from the past, I enjoyed the read and browse through the images.

Wm Franklin

Great information, but one error, and one omission: The first floppy disk was the IBM 2315,

which was 12" across, in a hard plastic case, and held 1 Mb. It was the main disk drive on the

IBM 360, Model 44, which I programmed in college. You omitted the DECtape, which was about

3" diameter, has a 2" spindle (center hole), and was 1" wide. The DECtape's claim to fame was it

was almost error-proof. You could unroll a bunch of DECtape; wad, crinkle, & fold it up in your

hand; and it could then be read and written without errors. The DECtape was used on Digital

Equipment's PDP-series of mainframes and minicomputers (PDP-8,10,11 that I know of). But

great post!

Bottlerocket

Way to make me feel old, guys. I actually used [i.e. programmed with] both punch cards and paper

tape. It felt high tech at the time. We would write batch programs using IBC job control language,

and then wait for the programs to run. It seemed high tech at the time, now it seems so old. I am

very glad you are keeping a historical record of computing.

Jacob

i got what i actually wanted from this website thank you

Perri Kenneth

I started selling the 8" and 10" SMD Drives. Remember CDC,Fujitsu. Emulex corp was one of

the first to create the 3rd party disk market selling up against Dec. We made emulation controllers

that put third party disk and tape products on the manufacturers cpu. This was back in the earlyeighties. EMC and Netapp were not even a dream yet. EMC made 4 meg add on memory cards.

They could not even spell storage. The days of the big iron wars. We were selling the stuff for

about $300.00 per meg.

read as a high-pitched, screechy sound while you were loading your programs.) This is actually

technically correct, at least for a short period of time... Before the Commodore branded tape

drive came out, they sold an adapter for use with an ordinary cassette tape recorder. It was a wire

that plugged into the Vic20 or C64 motherboard and then into the mic input of the recorder. You

then pushed play and record to start the tape drive and then ran the "save" command. It was a

REAL pain because you had to get the record volume just right. While it was recording you could

hear the squeals and hisses. The dedicated tape drive was really an improvement-- especially

because of the counter. With that you could put more than one program on a cassette tape. Yes.. Ihad both, the cable and the Commodore branded tape drive. That was a long, long time ago, in a

galaxy far, far away...

paresh

intresting improvement in technology.

Ecco

Regarding the tape sound - You had the correct phenomenon, but the wrong computer. The

secondhand Atari 800 I had as a kid used to be noisy as hell when you would load or save a tape

(CLOAD or CSAVE), though it sounded more like a robotic truck horn with a chest cold.

brian

interesting trip down memory lane. I have 3 old lugable computers sitting in my garage collecting

dust. combined they have about the storage space of my iphone

TerryGM

I remember the cassette tape drive of my first computer, Radio Shack's TRS-80 Model 1 Level 2.

It's hard to believe how many cassettes I used up learning that system. Later on I got a TRS-80

Model III with a 5.25" floppy disk. Of course as soon as I could I created flippies for it, to save

money and double my space. The orginal was only 180KB, by making another eye hole in the

floppy I could have another side to the disk. Later years I went to a school that still had some of

the Model IIIs in use. One had an external hard drive, about the size of three laptops stacked on

top of each other. It held a whole 5MB of data. It ammazed me at the time.

Charlie B

I remember seeing a product that would print programs on a laser printer that could be read by a

hand-held plug-in device. The output looked similar to the optical data storage area on the back of

some states drivers licenses. I don't remember what it was called but I actually did spring for one.

Programs could be entered in a blazing three to five minutes instead of hours! This made getting

programs for those Apple ][ computers much easier as we used to type in whole programs in

BASIC right from sources such as Nibble Magazine. (http://www.nibblemagazine.net/) It was not

uncommon (among nerds at least) to spend several days keying in a multi-page program that

looked cool. The rest of the world just wondered what we were doing.

Janet Carroll

There were also so mini punch cards in the mid-1970s that were 2"-3" square. They didn't last

long as the floppy came in about the same time.

Piyush Bakshi

That's a nice piece, back in 87' when I took computer classes to learn BASIC (I was in seventh

grade), we were required to get a 3.5" floppy disc. I got one too though never used it and I still

have it. It's an antique, Wonder what I'll get for it on eBay. :)

Chris

Hi. The relay on the Electron and BBC Microcomputers was to control the cassette motor, so that

it stopped after loading or saving. It may also have controlled the volume, but only with

specially-adapted cassette recorders. Hearing the data was essential! I remember getting my first

5.25" floppy drive, single-sided, 40K. It cost about 100. I also remember using the cassette relay

to switch my amateur radio transceiver between transmit and receive. We used to send programs

to each other by radio. Magic days!

Ivano Gutz

May I contribute with a missing landmark in the history of magnetic tape data storage? Its the

DC100 Data Cartridge, a 3.5" digital data and program mass storage unit developed to fit into

thee HP9825 desk computer, launched in 1976 with a 16-bit "triple core" hybrid microprocessor

fantastic for numerical processing, interfacing and automation and years ahead of the 8-bit

microcomputers from APPLE and IBM PC with 5.25" floppy disk drives. The quarter-inch-wide

tape minicartridge (QIC) & drive is much smaller than the 8" floppy disk & drive from the 70ties

(3.5" floppies appeared in 1981) and much faster and reliable than analog storage on cassete

tape. The QIC originated an entire tape-backup industry and evolved to capacities of up to

20-Gbyte. QIC-backup dominated the scene till surpassed in capacity and speed by the hard disks

in the 21st century. More about: http://www.hp9825.com/html/dc100_tape.html

Many devices used SHIFT REGISTERS as a storage media. For example, the early display

terminals ("CRTs") were in fact teletype terminals, operating at blazing speeds of 1200..9600

Bauds, connected to COM1 of mini-omputers and early PCs [*]. The display area typically had

24(/25) l ines, 80 chars/line, for a total of 1960..2000+ characters (25th line: status data) which

needed to be stored somehow. A shift register is like a bench, a row of chairs. Put many of these

around a clock until the end of the last bench touches the begin of the first one. You now have a

circle, a ring with thousands of chairs arranged around that clock. The way it works, on every

chair sits either a "0" or a "1". Each time the clock ticks they all stand up, make one step to the

right and sit down again. The last one on every bench now sits in first place of the next bench

and... The electron beam, as it is redrawing the display advances to the same clock beat. After

every 7th tick it gets to see who sits on "Bench No.1" and displays the graphic that corresponds to

the 7 bits sitting on this bench at that instant. Say new data arrives, bit by bit it is entering the

circle at some "Bench Nr.77". As new bits enter bench-77 the ones leaving bench-76 are lost as

they step on a trap door and fall into the bit bucket. [*] The alternative was memory mapped

video, a portion of the PC's RAM used as video buffer and a graphics card (CGA = IBM/PC

Color Graphics Adapter), converting the RAM content into RGB video signals, sent a video

monitor (a fast TV without tuner/receiver circuitry).

David: Looks like a control panel from some Unit Record device. Similar to those for the

402/408, but probably a one-off machine. Wired a lot of machine in early 60's. BTW: If you tuned

a radio between stations and set it on top of an IBM tape drive, you could create music on it by

the data you sent to the tape. Knew a chape who spent months to make it play Mary Had A Little

Lamb.

My dad just turned 70 last week and when my roommate showed him her iPhone he was amazed

(he's not real techie) It got him talking about hen he was in the Air Force back in the 50s and early

60s they had whole BUILDINGS for just one computer that couldn't do what a pocket calculator

can do. I worked in a hotel several years ago that had a mainframe computer that took the 8 inch

disks that had a whopping 76K on them and used tapes to run the back-ups. Seeing the pix of those

"floppies" brought back a lot of memories. Great article

I worked on an IBM air defense computer system starting in '61. 56,000 vacuum tubes,

2500 miles of wire, 1 million semiconductor diodes. We used punched cards, magnetic

tape, magnetic drum memory, and the system had 65,536 words of 32-bit core memory.

I have been in the computer industry since then and have lots of great memories of the

changes in technology over the years.

I recall a description of a system that used a video camera pointed at an oscilloscope to store 32

bits altogether.

Tom Cagan

Back in the mid to late 1960s, I worked on the Litton DIANE system on the Grumman A-6A

Intruder. Our support bench was called a SASE, and was driven by a paper tape/aluminized

mylar tape system. When we had a correction to the program, we got a slip of tape from Litton,

and cut and "patched" the correction into the tape. Today we are still "patching" our systems. Also

in the DIANE system, there was a drum memory. It sat between the B/N's(Bombardier/Navigator)legs. If I recall, it was 144 tracks, and we had to do two fetches of 4 bits,

to make a one 8 bit, byte. We didn't even have ICs then, a gate was built "chord wood" style and

was one inch square on each end, and about one and a half inches long.

Hey Keith! I came to the comments to make the exact same comment about mercury delay lines

Here's another person who remembers that the old Atari 410 cassette recorder for Atari 400 and

800 computers did play the amazing screech erroneously attributed to the Commodore. I'm fairly

confident that the only reason the screech existed was because you'd surely think the system had

hung if you didn't hear something. At an effective read/write rate of about 35 bytes per second

(600 baud with long inter-record gaps), reading or writing a file took forever.

The Atari cassette recorder was stereo, one track was intended for audio and fed to the

TV speaker, the other was for data. Most commercial games were recorded in mono, or

used the audio track for anti tape-to-tape copy protection exploiting head alignment

errors, and I seem to recall that the Atari itself recorded data over both tracks.

The chip that decoded the tones to data had no reset pin, and the OS used it in whatever

state it powered up in, so data transfer wasn't as reliable as it should have been. It was

possible to reset the chip by manipulating some of its registers, I wrote a program that

did that and could load data at much higher speed, although I could never get the Atari

to reliably save above 1407 baud, other than by manipulating tape speed.

I love the fact that the HAL 9000, with its ability to recognize the movement of lips and human

drawings, was running off of punch cards. For those of you who don't believe me, see "2001" and

fast forward to the point where HAL detects the fault in the AE-35 unit. Dave will ask for a hard

copy of the report, and HAL prints out an actual punch card.

What about the Kado (not sure of the spelling) I rember my Dad running one in the Early 80s' it

We always strive to make our products as easy as possible for our customers to use.That even includes such seemingly mundane things like input of credit card details.

For a short while now weve been testing new input functionality and design for credit card payments. One ofthe new features is that when the customer types in the credit card number, it will automatically switch to thecorrect type of card.

Check out this video for a bit of the background and a quick demo of what the new design looks like.

This was a day packed with information, often very detailed and technical, aboutall different kinds of aspects of web performance.

There is an official summary of the workshop, including links to the presentations, but we felt we should giveyou some of the highlights.
