I believe I've found some errors in
JA-Ace4000-Manual-[updated-110304].pdf in
Ace4000manual.zip http://www.jupiter-ace.co.uk/usermanual.html .
I post them in this group since the Jupiter Ace was developed by some of
those who developed Sinclair ZX81 and ZX Spectrum.
The other Jupiter Ace manuals seem to have the same errors. I read the
manual using PDF Viewer 0.1.7 on Linux. I tested the examples and did
most of the exercises with the emulator xAce 0.4.1 on Linux and those
using sound on the emulator Ace32XP on DOSBox for Linux.
I use "'" or '"' to quote, and right-arrow '-->' means that the
quotation should be changed to the following text. There may be errors
in my corrections and please let me know if you find some.
I would like to know if the Jupiter Ace4000 Manual is updated so I could
check the new version.
I think it's great that they made the manuals available and I've learned
a lot. I guess most errors are due to scanning and OCR but a few are
more complex.

Could this be the oldest finding of an error ever?
Was the Ace simply a zx81 with differnt rom?

some are probably in the original manual which I don't have access to.

components, i.e. it had no ULA. It had 3 Ki RAM. 1 Ki RAM was used for
128 redefinable characters and a part of 1 Ki RAM was used for display
file. Jupiter Ace could generate the display without using the CPU so it
run like fast mode ZX81 but with display. The character RAM was
write-only. Jupiter Ace also had sound through a speaker.
