One of the things I have half a mind to do is an interface that could be a TrumpCard or a SuperQBoard, should be fairly straight forward. 64K ROM with both SuperQ & TC roms, CPLD with the decode and select logic in it, WD1770/1772 and a 1MB static RAM chip, though obviously some of that would never be used. I guess the only component that would be hardish to get hold of would be the WD177x. I seem to remember that a WD1772 VHDL model exists somewhere. Might be the Atari ST FPGA project? There is also the HxC floppy emualator in FPGA. http://www.torlus.com/floppy/ It might not be out of the question to design a modern Trump card with SD slots.
