A2000 CPU slot for A500?

My hack

Still working on a schematic... If I make one, I would like to have a PCB built.

Anyone have an idea where to get the card connector strips from? I have done a quick search on the Dick Smith and Jaycar sites here in Australia with no luck...

I haven't understood what kind of connector you refer to, not the slots but "pins" themselves?
In any case, try asking to electronic components resellers in your city, I bought all the items from non-online sellers. Even found 86 and 100 pin slots :-)

I would be interested in building a CPU slot only adapter too - finally a way to get an 040 into my A500!

Then you mainly have to compare the schematics of your A500 motherboard revision with the ones of the B2000: most of the signals are the same, while some other ones require a little of TTL logic ICs for generating them.

Please note that, if you need the 7 MHz clock, the A500+ motherboard (rev. 8A) supplies it to the expansion connector, while the later A500 one (rev. 6A) doesn't, but it has a jumper that, when closed, makes it available, so it's simpler because you don't need a TTL gate :-)
