I just inherited an old (as if there's anything else) ZX80 in its polystyrene box with a few manuals.
I've tried tuning the TV into ch36 which is apparently where its output freq is - there's something there, but nothing really visible (intermittent signal?)
The thing is, it's of no use to me whatsoever but maybe it is to someone here.
The manuals are as follows:
A course in BASIC Programming - ZX80 Operating Manual - Ring bound booklet
The ZX80 Companion "THE MONITOR REVEALED"
and finally - 30 programs for the Sinclair ZX80 1K - again, ring bound booklet
Now if anyone is remotely interested, please mail me chairman@rblr.co.uk.
Call me Mr Cynical but it's not going for nothing but reasonable offers gratefully accepted
Cheers
