A2000 cpu slot -> A500 edge connector adapter?
« on: November 06, 2025, 09:47:20 PM »
was looking at the Individual Computers ACA 500, and wondering if a passive slot adapter in the A2000's CPU slot would allow the ACA500to work in a 2000.

I have some A1200 accelerators sitting gathering dust now my 1200's are pi-stormed up, and was wondering if i could get one running in a 2000.

everything seems to line up, but just wondering if there are any reasons why not?

pin 9 - 28Mhz, pin11 - Config Out - do i need this for zorro cards to work? & pin20 - BOSS, are not connected on the 500
pin60 - Bus Request and pin64 - Bus Grant seem to be handled by logic on the A2000, but on the A500 go straight to the CPU...
otherwise all the pins map directly.

tempted to test this by buzzing out the pins on an A500supraturbo28 i've got ,and seeing if can get that to work.

A500, A600, A1200x3, A2000, A3000, A4000 & a CD32.
and probably just like the rest of you, crates full of related "treasure" for the above XD
