I was reading in another thread just recently that you can fry an A570 if you use it with anything faster than a 68010. Glad yours survived your experimentation!
I saw this other thread and seeing many comments I guess I am really lucky. mmmmmmm, I wonder specifically what would make it fry? I did not expect the frying effect. An accelerator should not be causing the frequency of the A500s Zorro I slot to change. The A570 is amazingly not standard, funny how it was made by commodore.
This comes back to my original question, can the ACA500 be used with other Zorro I or Zorro II devices? I am consider ordering an ACA500, if I can use it with other devices.
I cannot help but wondering if it a power line issues. Ie either the +12 V,+5 V, -5V, or the ground, get pulled down. Accelerators can use a significant amount of power. I had a big Pee Cee AT power supply hacked to run the A500.
The GVP's power is isolated from the A500s (although you can hack this). This kept the GVP from overloading the A500's power supply.
