I'm acquiring the bits to adapt an A2000 accelerator card to an A500. It's going to connect to the side Zorro slot to start off with and hopefully develop from there - I just want to get it working first. Basically, comparing the A2000 CPU slot pinouts to the A500 Zorro pinouts, they are VERY similar, with only 4 pins different.
I just need to get a bit of an idea of how different/important/necessary to connect these pins are...
A500 pin 9 is not connected - A2000 CPU slot pin 9 28mhz clock
A500 pin 20 PALOPE - A2000 CPU slot pin 20 BOSS
A500 pin 60 BR - A2000 CPU slot pin 60 CBR
A500 pin 64 BG - A500 CPU slot pin 64 CBG
Can anyone shed some light?
Hmmmm - I wanted to build the fastest 68k A500 using an 060 accelerator board for the A2000.
For that project I bought the Micronik Zorro II busboard (

Unfortunately I never found the time to realise this project - so the busboard still lies in a locker - still "brandnew" and unused...
