Someone gave me one of those the other day...can't be that old as it has a PS2 connector. It was too nice to chuck, but if anyone wants it, let me know...you pay postage from Aussie (and they're not light!) I'd love to see it go to a good home.
This reminds me of the "BiTran 6" computer I used at Penn Technicial School. It used 7400 logic chips but was programed using binary. I remember for my senior project I programmed it to solve the quadratic equation. The good old days ....
Max obviously has not seen this yet....eat ya heart out Max!!! A serious labour of love though. I see he uses a 32K x 8 static ram chip for memory....cheating really, though it's excusable - if he did that with relays it would take up his whole lounge room. Pity he did not use ferrite core memory or something else from a bygone era for that.
I always loved the sound of a keypunch. I had a friend who called them "pea-kunch machines" because that's the sound they make: p-kunch, p-kunch, p-kunch followed by the satisfying hiss and klunk-klunk as the card is released and a new one loaded.
Oh man, my co workers would kill me. I get aggressive with mechanical keyboards. By the end of a long sentence I'm furiously pounding on it just for the satisfaction of the RATA-TAT-TAT. You don't even want to see me use a typewriter with a manual carriage return.
I need to stay away from those for everyone's sake.
I've been following passionate people doing home projects for years and years. This was one I saw a long time ago that I thought really deserved some fresh attention. There's just something so satisfying about hearing those mechanical switches clicking and clacking, I'm glad my laptop doesn't do that, but I kind of wish something in my house did!
Blog Doing Math in FPGAs Tom Burke 3 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
