Yes, the 1.0 ROMs could not load/save from disk. Only tape. And it
has some timing bugs there too.

Btw, for proper emulation of the 2001, you should make a character ROM
with (for upper/lowercase mode) the upper and lowercase characters
swapped. When they swapped those in the 30xx machines, all programs
with lowercase characters broke. And they turned Li into lI, which
looks a lot worse ;-)

It should be.

Another thing. This weekend I got a 8032 (a square one, finally) with
some kind of graphics board. Unfortunately I did not write down the
company name it had printed on it. But I don't think it was a VisMem
board (it didn't say so, at least). Also unfortunately the machine
does not work. I guess I should try the board in another machine and
hope that that works.

I certainly will.
