A600 8Mb fast expansion

Minimig can use a 64 MB dram directly. By just replacing the current sram chip. And change the HDL-code.
So no need for a particular "ram expansion" per se.

The question is rather what to do with any ram above >16MB :-D

Which drams could it use directly? I haven't seen any electrically compatible 44pin tssop drams that would fit or have I misunderstood?

When I ordered my sram from digikey they sent me 8mb chips instead of the two 1mb chips I ordered.  At least that is what is on the invoice.

I'm at work so can't check my invoice to compare but I'd bet they're actually 8Mbit rather than 8MByte, i.e: 8Mbit = 1MByte.

The only way to get more ram on the MiniMigs is to attach something like the A600 8Mb fast expansion this thread is all about, which might be possible actually. Or to redesign the MiniMig board a little to take either a lot more SRAM (expensive) or cheaper SDRAM. Either way it'll need a new board I think.

I did take a look at using some of the spare IO on the MiniMig 1.1 board to try and do some "dead-bug" style modding with a single 64Mbit SDRAM chip but I don't think that approach would actually be feasible for a host of reasons. Besides I'm still building my FIRST MiniMig! :-D
