Sounds like it's not reading the bootstrap ROM properly. Open it up and
reseat the ICs in it.

Hi!
I just picked up an MZ-721, which is rather neat. Oddly, it loads Basic
from tape, which seems fairly unusual for a cassette-based system.
Anyway, when I switched it on I got nothing but garbage on the screen,
and ning I do seems to change it at all. Shoud I consider this a dead
computer, take photos and treasure the manuals? Or is this the sort of
think which *may* be repaired, so I shoudl track down someone who fixes
these things and get them to look at it. Indeed, is it even worth the
effort?
I tried to find information on it, but almost everything seems to be in
Japanese. :)
Thanks heaps,
Adam.
