Any recommendations out there for good Nascom resources?
I know nothing about these creatures; I went round to pick up a Torch
floppy drive unit from someone a few days ago and they happened to ask
if I wanted a Nascom before they threw it out...
It's housed in the biggest, ugliest wooden case ever so that's going to
have to go! The system board is a Nascom 2, whilst the PSU says Nascom
3a - maybe there was a crossover point when that practice was common?
If you get no other help, I should have the schematics, etc, for all that
stuff....
Inside there's just a system board and memory
board, and no bus slots
for anything more - is the bus anything standard and were other 3rd
party boards typically added to these machines?
The bus was Nascom special, and was also used on the Gemini (with a few
modifications). Yes, there were 3rd party boards (I have one somewhere
with the Digitalker chipset on it IIRC). It was a fairly popular hobbyist
computer at one time...
However, the CPU board + memory board is a fairly common configuration.
IIRC, there is RAM space on the CPU board (using 4118 1K byte SRAMs). At
the time, there was a ahortage of said chips, so Nascom supplied the CPU
board without them, but offered the DRAM board at a very good price.
Needless to say that's what most purchasers bought.
Still, a curious one, and my first wooden cased
computer. I'll have to
The case is not original (altough, strangely, my Nascom is in a wooden
box..) Originally you just got a pile of PCBs...
