So, this is a real "on the off chance..." type of post. But if I'm going to find the answers, I'll get them at this amazing place.
Around 1992 or so I was doing my A-Level (sixth form) Electronics class. Whilst the focus was on basic electronics, one of the topics covered was, you guessed it, assembly programming on a 6502 board. To be fair, I didn't really know what I was doing on this board. It wasn't like any computer I'd used before, but it was still fascinating. I remember we had some tasks given to us, and one of them was to program it to play a tune. I was the only one to use a lookup table; I guess that speaks volumes for the rest of the class.
Anyway, I'm desperate to find out more about this board. I've hunted high and low but I can find nothing and none of the similar boards I've found match what I can remember. Obviosly 22 years is quite a while, and my memory may well be faulty. However, some things I do remember:
* Definetly 6502 based
* Traditional hex keypad and 4 or more likly 6 7 segment digits with program entry by writing to RAM, presumably with a simple monitor in ROM
* I'm fairly sure the keypad had largeish white buttons?
* Fairly sure the computer was spread over two boards
* Had a piezeo sounder
* Again my memory is possibly faulty but I seem to remember the PCB was an unusual blue colour
I suppose it's possible this board was some custom machine, perhaps even made by the college I was studying at. But on the off chance my rough description has jogged someones memory, I'd love to know about it; what the board was, and where I might find one...
Thanks! And sorry that this is all very vague....
