is it possible to rebuild old c64 hardware enhancements?

I can believe that; chances are that it would come with one chip, and you can't get 8 MB SRAM in one chip. If you're willing to build your own board, you could put 4 of the 512kx36 SSSRAMs I mentioned onto a board. It could probably be a daughterboard, to plug into an FPGA eval board that has an expansion connector. (If that doesn't work, life gets harder because you may not be able to get a decent FPGA in a package other than BGA. I don't know about you, but I draw the line there for hobbyist projects...) I'm still sorting through this for a project I'm working on that needs 2 M x 60 bit memory... that seems to be too much for sane SRAM. Fortunately I can cope with DRAM latencies there. paul
