Its an early Kindle, slide the top over and put in a SD card and you can read very old books ( Old Testament only )

You been at the "grape juice" for which your part of the world is renowned?

Actually we live right next door to a government school: I hope it's not an indication of the computer lab equipment....

If you can find a few more, and some cable ties, you can make one of these (http://www.apartmenttherapy.com/how-to-make-your-own-floppy-di-149089).

I have to have one.... our local hardware place even has bags of those small cable ties in an assortment of colours, not just the common black or white. But my wife says she threw out a gazillion of those 3.5s a while back.

If you find some 8" ones you could make dustbins for under the desk....

I made some a few years back. I even found some new disks on sale that I bought for the purpose, because they were multi-colored. I made them for the kids in their school colors.

You guys and your new fangled magnetic media. I had to enter my first created program ( a slot machine game written in machine language with a paper and pencil 'editior' ) via the front panel switches of the minicomputer. So get off my lawn.  :D

I don't go back quite that far but did start Fortran on punched cards.

That's the beast! Ours had a placard affixed with the bootloader, it couldn't have been more than 20 instructions or so. Of course the system had core memory, so if it was powered off, you could just try it on the chance that the bootloader was still there after the last person used it. I thought that a person could have some fun with that, but never quite got around to it.

USPS International Small Flat Rate Box is like $15 IIRC.

Ah, there we go.  $17 is the lowest priced option I can find.  Still a bit steep to send five used floppies.  I suspect @JimboZA could offer a fiver to one of the kids and have a much faster delivery.

You guys and your new fangled magnetic media.

Oh.. we're on that subject again.... ;)

University: Punch card for FORTRAN. Batch process get your print output. Edit, shuffle and resubmit. Repeat.

First work: Papertape into a PDP-11 (and toggling the bootloader. But then we got a board with 20x16 Diodes in a matrix and an addressdecoder. Some diodes were cut and - tada! - we had a ROM address space with the papertape bootloader)

"Patching" was very real on the papertape. You cut some extra holes or used black tape to block some. (there were some tools/jigs so the holes were proper aligned)

But then things went ... well, modern like. 8" floppies, double the core to 16Kilobytes, even 24K.   8)

I kept some of these for my vintage systems. Was lucky that someone sent me some 5" 360K single side discs to make a copy of dos for the compacq, very first luggable ibm pc and very first compaq.

There is a panel in my work place that someone kept. It's got hundreds of jumper wires on a matrix of holes. He said it was a program someone made. That stuff IS older than punch cards.

Me too (WATFOR)... you forgot the "drop on floor and accidentally stomp cards" part.

I remember running back to the computer centre between lectures to fetch print out only to find it hadn't compiled due to a silly syntax error. Then there would be no vacant card punch, then late for next lecture.

That's what the sequence numbers in columns 73-80 are for.  You just put it in a card sorter  :)

That's what an exacto knife and scotch tape are for.   :)  In addition, I recall occasionally having to program in Pascal on an 027 card punch when the 029 card punches were busy, and having to multi-punch things like semicolons.

Not sure about the model numbers and other specifics, these were just slightly before my time but I do think I remember them being wheeled out the door. I did have an assignment for a few weeks once that involved operating a card sorter. If a jam occurred, it could create quite a mess in a hurry.

Jack,

That looks like it came out the same era as the one at my work place. Must be pretty old. My only experience with punch cards was using them as note cards and bookmarks.

Liudr, yeah, when I started working they had a "Tabulating Department" that was full of that equipment with those plugboards.  Never became familiar with it as the writing was on the wall and the mainframes were beginning to occupy the next room over.  This (https://picasaweb.google.com/111936317114713763659/20130128?authuser=0&authkey=Gv1sRgCPa4qaeo0qLrMw&feat=directlink) is the only souvenir that I managed.

Those plug in wired matrix panel were what we used at a NASA tracking station in the 60s to configure the equipment for the next satellite,  it actually worked very well.
We just had a rack with one panel for each satellite and the main components were connected in a couple of seconds.

I must admit though, when we used to load a new game on the Sinclair "computer" , from a an audio  cassette,  ones imagination run wild with 5 minutes of modem chirps and whistles until it loaded .

That spaghetti board reminds me of grad school. We had an IBM 1620 that was kind of like our own PC that we could do whatever we pleased with. The IBM reader-punches were programmed with a plug-in card very much like that spaghetti board. If you changed that board, you could punch and read cards that had a completely different coding from normal. I carefully keyed in a very long program before I noticed that the last user had not removed their custom programming board. Doh!

Yeah, I have a few APPLE ][ cassettes in my vintage computing collection. I remember that old time (80's).
