The PETvet is a RAM and ROM replacement board for the Commodore PET, and potentially other 6502 based microcomputers. The PETvet connects to the 6502 socket in your PET, and allows you to select your boot ROM via jumper settings. It also allows you to view the memory of a running PET using the replacement RAM by halting the CPU and sending the memory contents over a serial port.
The PETvet is currently available, fully assembled, for $70 USD. This includes SRAM to fully replace the RAM and ROM in your PET (or only parts of the memory map, if you want). Or you can just use the one from your PET.
It is not necessary to remove the existing RAM/ROM in your PET to use this, although you can if you like. The PETvet is able to selectively access sections of memory from either the mainboard or from the PETvet RAM, depending on a configurable ‘mapping RAM’.
The PETvet is also available as a kit by special request.
