Re:
It's possible to wire up an adapter that lets you use a ZX81 (or was
that TS 1000?) RAM pack on a Jupiter ACE ... I've seen one such working!

The Jupiter
Ace had a 4K RAM pack as well as a 16K one, and if anyone has a
spare Ace (UK) or Ace 4000 (US) I'd be happy to take it off them :o)
The Ace memory is a little odd. The basic machine has 3K of RAM, all in
2114s. 1K is for Forth words, 1K is video memory (unlike the ZX80/ZX81,
this is not taken from main memory), 1K is the character generator (so
all characters are, in fact, user defineable).
