Re: EA Mini-Scamp

I can understand that! It took several months for me to get it going at
the time (hey, I was 16 or so - gimme a break).
It was all down to the (alleged!) self-stripping-through-heat enameled
wire used to make the 1000 ;-) or so links one the single sided PCB.
Turns out it didn't, most of the time!

I wonder what my Natsemi SC/MP Microprocessor Applications Handbook would fetch
nowadays :-)

I built a Scamp from the Nat Semi eval kit around about 1977. It didn't have
a fancy case like this, but it did have an ASR-33 as I/O device.

Re: EA Mini-Scamp
something !

My first assembler language programming was on a Signetics 2650 eval
system (8k ram, load/save to cassette tape) in early 1977, then I
moved on to one of the first Apple II (6502 cpu) to arrive in aus
later that year or early 1978 (??). I used the M6800 eval kit in
1980, and the DREAM o/s author (Michael Bauer) was one of my tutors at
Uni when it came out. Programmed lots of other computers too in the
late 70s, from micros up to mainframes, and haven't stopped doing it!

Re: EA Mini-Scamp

I built that one too, but before that I built the 'baby 2650' EA project.
It only had 256 bytes (1/4k!) of RAM, and 64 bytes of that were used
by the monitor program, Pipbug. I still managed to write a 'Nim' game
program within the remaining 200-odd bytes, though ! Still got it somewhere
in the files.....
