That's the model I got new back in 1979...

Could be ROM, could be dirty sockets.

2532s are drop-in replacements. Note: *not* 2732s.

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).

I can't help you from here, but the C-64 burner _might_ be able
to burn 2532s.
