Hello,
Today, I received the PETVet from Mike.... This is my first experience with this wonderful device. Like Tezza said, the analogy of pacemaker to a human heart, the PETVet is for the PET.
From my experience on my PET2001-8 repair, having built Scouter3D PETROM/RAM replacements, I should have been content with the setup.
However, the PETVet as is gives my PET2001-8 additional (new) specs:
1. New set of ROMS ---BASIC 2 ROM
2. Additional memory -- 32K of RAM
3. Flashable ROMS
4. Additional features...see documentation at bitfixer.com
....

...notice that I still have that screen anomaly (location 513 character on the screen).
Well, I emptied out again all ROM/RAM sockets, took the MOS6502 cpu and plugged it into the PETVet board.
The PETVet comes with 3 switch settings. SW setting #1 is for my PET2001. Mike has already set it up for me. I referred to the first PETVet documentation just to confirm things are set properly.

The PETVet has a 'socket-header-socket' combination which would allow it to be plugged in to the 6502CPU socket on the motherboard. It sits perfectly, right height and right placements.
Here are some of the first pics I made...

I loaded the first CURSOR#16 cover from tape, ran it for a while and left the PET as if it is on a 'burning test'.
Everything runs cool (ATMEGA, RAM, ROM and support chips) or 'just warm'. However, the MOS6502 chip has a hot spot on the middle. I might take a small heatsink in glue it on top of the 6502 chip --give it a longer life.
Here it is in action!!

New Life indeed to an Old friend! PET2001-32
