Hi,

I'm looking for a method of adding (any amount of) FastRAM to my A500+...
However - I want to try to keep it completely internal to the main case (no sidecar).
For info, I have a CFIDE68K on the cpu socket, KS switcher, and 1mb Chip RAM trapdoor upgrade installed.
Looking for a schematic / circuit diagram (if there's not an already-made solution?)

Can anyone help?

Thanks!

Are you looking for a FastRam schematic or the A500 Schematics?

FastRAM schematic please, so that (if I had to) there's a possibility of making my own fastram board for internal mounting to the A500+. Because I have a CFIDE68k that unfortunatly means I can't use a CPU expansion board.

This is all of course unless there is already a (readily-available) fastram internal board in existence........

They exist, mate.

Look for a Base Board, which will let you have the whole 2Mb and more 3Mb of FAST RAM.
