Hmmmm. I was hacking Galaxian video games at that time
and my employers =
bought a Nascom 1 for me to use as a 'development platform'. The =
hardware was quite similar to many of the pub game machines back then.
I have a Nascom II which I bought some years back and got going again.
And a thing called a Gemini Calaxy which is a somwwhat related machine
(NASBus compatible boards, etc) with a hard disk and a custom network
interface. The latter had all the numbers sandded off the ICs to make it
'impossible' to reverse-enginener -- it puzzled me for about 10 minutes...
