That latter's the important bit; there are just too many computing-related 
projects in magazines of old for which the software / firmware had to be sent 
away for - and of course whilst the magazines (and hence schematics) survive, 
the code which they ran has typically long since gone :-(

Hmm, that name rings a bell for some reason.

I'll have a look if I remember; I think we've got a pretty comprehensive set 
of ETIs from around that period.
