Been there for a year.. so no prizes for you :lol:

I have several 'Bad DMAs' that should be ideal for this project!

:dizzy:

Might be easier to see with this image...

Oh yeah, much clearer thanks :)

:bravo:

BTW, where does the RAM board fit, on the connector south of the Glue, or the connector south of the MMU? EDIT: Ahh, wait, just looked at your Falcon RAM board, and I'm guessing it uses both :)

RAM board fits above the MMU... I guess it could use my 4MB MMU plug-in board also.. Never really considered it..

Atari freaks did have some 1MB Falcon RAM board on eBay last year that I cannot see any at all on there now :roll:


They look like this..

I take it that there will still be a limit of 4MB RAM initially?

Yeah.. until the MMU is replaced with FPGA.. but won't be any time soon..

The Falcon RAM board will be gone then, it will be smaller SMT SRAM on a plug in board probably.

Ok, cool.

where do I put all these 4164 rams chips i've got hundreds of?

Not wanting to get ahead of myself, but how about another version down the road that fits a micro ATX case ;)
