That sounds about like it. RAM is 4 ea 2111A-4. There is an unmarked
1702 EPROM (A15) and an empty socket (A16) next to it. Does your's have
an IC in A3? If so can you tell me the type? Is there supposed to be
something mounted to the left of the keyboard? Mine is barren but there
are screw holes there.
I picked up an 8080 bread board trainer made by E&L Instruments this
weekend. Does anyone have a manual for it?
If this is the board I think it is [8080 + 1702 KEX ROM + 256 or 512
bytes RAM + 3 output ports going to LEDs + octal keypad + breadboard]
then I found one at a radio rally last year.
I mentioned it on the list, and somebody (I forget who, sorry) posted the
source for KEX, which is enough to figure out how to use it. I can send
said listing to you if you want it.
Yes I'd like to see it.
THe hardware would be _trivial_ to reverse-engineer (about 1 hour at most
IMHO...). I must get round to it...
That's my problem, no time.
