Hi,
a couple of days ago my Pet 2001N (the 2000 Model without
the cricklet-keys) gave up :(
That's the model I got new back in 1979...
... When trying to boot it puts random characters on
screen. As far as I found out this _should_ be a ROM-Problem
(could be RAM too, but I hope it's ROM as I ran a Ram-Test
successfully before the Pet died).
Could be ROM, could be dirty sockets.
Could somebode please provide me some Info, what
Eproms I
could use as replacement for the original Commodore ones (Basic 4)?
2532s are drop-in replacements. Note: *not* 2732s.
I'm
also a bit confused what image I should use (see
http://www.funet.fi/pub/cbm/firmware/computers/pet/index.html)...
The 2001-N (dynamic RAM, graphic keyboard) is also known as a 3032
in Europe. Look for images related to that model. It is _not_
a 4032 or 8032 (those have a 6545 CTRC for video, not discrete TTL
components like the 3032).
PS: It'd be great too, if somebody could provide
me burnt
roms as my only eprom-burner is for C=64.
I can't help you from here, but the C-64 burner _might_ be able
to burn 2532s.
