As it would be 68k, no use in any DRAM over 16mb as we can only really use 4mb - 14mb range for alt-ram anyway. I did get the xlinix chips, don't think I decided on a RAM yet though. RAM would need to be quick to use up to 60mhz CPU. Such a board would plug right into a H4. The 5v sram ones I designed end up costing towards £100 mark.. Its why I wanted some help with your dram controller stuff to design a cheaper board.
Fire what you have in an email to me. I'm in bed ill right now and the only thing keeping me sane is the Critical Drinker youtube channel.

Alternatively I could brain damage the TF536 to one SDRAM and a XC95144XL? Keep IDE?

I think that's probably a good idea as the ram is relatively cheap as well as being fast.
If it ain't broke, test it to Destruction.

Maybe. Haven't looked at that design. Though it has to be a 68k footprint, so wouldn't be room for anything else like IDE. Keep it simple, compact.

I quickly checked this out and i cant make a T100 chip fit inside a 68K socket and the VQ64 isnt big enough to run an SDRAM alone. Not enough pins or macrocells.

ah crap. it must be larger than the PLD's I use then as they just fit :(

False alarm.. i was being an idiot and trying to squeeze them in at 45 degrees.

Just a quick question though... why perfectly 68k? cant we extend 1cm in one direction and have IDE?
