BASIC 1 did not come with the "TIM" monitor - I started on a 4K PET at
our local main library, so when we got a 2001-32N (3032), I was very
surprised and pleased that TIM was in ROM.

It is quite simplistic - you can dump memory, alter memory (in hex),
load and save blocks of memory to tape (disk, too, AFAIK, but we
didn't own a floppy drive back then) and jump to a point in memory.

It's still lots better than nothing.
