I added, IIRC, 28K to mine. Even with piggy backed chips with one 
address pin bent out, some of it was still hanging out of the back on a 
ribbon cable:) Oh, and an overclock to a whole 2MHz. With an early 
equivalent of the "turbo" button you used to get on 486s, consisting of 
a light switch screwed into a hole cut in the case, to make the timing 
sensitive stuff work.

And BTW I thought the Z80 was a much better chip than the 6502 and never 
understood why Acorn/BBC didn't use it instead. But the ZX81 was 
horrible and the Atom was a much nicer machine as a whole. IMHO of course.
