Performer Pro in a Mac Classic

I could never seem to get my Classic to boot with the MicroMac Performer sitting over the original processor - so I finally recapped the accelerator and cleaned the socket clip and if finally boots. Oddly enough the Tash20 device that works normally w the classic no longer boots w the accelerator in. I wonder if that's related to it having a 68030 since the tash20 doesn't work w the SE30 either. Anyway, I feel the pride of a conquest by just having it boot - I now need to grab the driver and stuff it in a new hard disk and add an FPU for the "Max" Classic experience short of just sticking in a Classic II board.IMG_6979.jpeg
 
Interesting - Is J5 just a pass through for the floppy disk? I wonder if that is partially to provide another support point for the card?

It looks like it has some cache onboard - I wonder how much faster this board is versus the more simplified cache-less boards. Nice card!
 
What does the accelerator do with the ROM of the Classic? If it patches the Sony driver, it's possible that it gets rid of the HD20 support.
