Hi
The main difference between the US and European Ace was that
the US one was slower and had a different divider circuit for
the video ( slower because of the crystal used to get video
right ). I have a US version but know people that have the
European version as well.

Not strictly true; it was designed by Richard Altwasser (hardware) and

both had previously worked with the ZX80 (Richard) and 81 (Richard/Steven)

design is more ZX80 than 81 in that it's a single board machine with the
membrane keyboard incorporated on the mainboard.
I don't think there were any differences between the Ace and the Ace 4000,
though I'm sure US ones had a slightly modified case in that it had an extra
'bump' in it!
It's typical that all that stuff comes up when I don't have a job - I'd have
all of it :)
Anybody who is into this system should check it
this auction I found on
Ebay:

074514971
The guy also has some nice Commodore stuff, a Sony (MSX?)
System and some
other cool stuff too.
The coolest item there, for me, is his Jupiter Ace. For those who don't
know, it's a FORTH machine, and fairly rare. It's based on a Sinclair
ZX81, and named after the Pilot ACE computer built in 1950 at the National
Physical Laboratory.
