Use ACA620 in a 500+?
 

Do you think it could be possible to use the ACA620 in a 500+ if a suitable CPU adapter was made for it?

I think the 500+ is generally very similar to the 600 in terms of having more or less the same custom chips. Only main difference is the IDE controller and PCMCIA.

The ACA620 is a very nice accelerator and it would be cool to be able to use it in a 500+ as well. :)

You'd never be able close the lid but sure. Much better off buying an ACA500

Then you wouldn't have a lid to close... :crazy

Not sure if it will be that tall. I think it should fit inside, although maybe not with the top shield on. It shouldn't be much taller than the Kipper2k CF board with the CPU adapter.
ACA500 doesn't have enough memory and is just a 000 CPU, so you'd need to upgrade it with an ACA1220 to have comparable performance to the ACA620. Then it becomes quite a lot more expensive than the 620, which only costs slightly more than the ACA500 in itself. Also, I prefer to keep everything inside the 500 chassis.

Ok, you might be missing the IDE interface(s) and the ACA620 might not work with the Gayle-style IDE controllers that exist for the 500?
