I hope this is not a single-instance machine :-)
Nop, dream ended :)
A few years ago I was given a Sharp MZ80-B computer +
disk drive.
Yesterday I got the user manual for the base machine, including the full
schematics :-)
Need !
Anyway, I've had a quick look at my machine. It
appears to be pretty
stuffed. The 3 internal options - extra 32K RAM, 8K graphics RAM 1 and
the expansion cardcage are all installed. In the cardcage is the 8K
graphics RAM 2 card, a floppy controller, a Sharp 16 in, 16 out user
port, and a homebrew card (4 TTL chips, so it's going to be trivial to
work out what it does)
THe MZ80s are basicly Z80 PETs :)
What I don't have is any software. All that's
in the ROM is a bootstrap
for the cassette or disk. There's not even a machine code monitor :-(. So
I am totally stuck.
There is - or at least should be - you are able to dump mem,
change mem and start a programm.
Does anyone have one of these machines or know where
to get the software
from?
I'll have to look, back home are at least two books (and maybe some soft).
Gruss
