This is amazing! Time to fire up my Atari Falcon again (anyone out there willing to sell a CT63?) These schematics could be used to implement the entire Atari STE's or Falcon 030's in a single FPGA. In phase two, new chips could be added, or existing chips enhanced (Blitter with texel and shading support, anyone?) The best part is, as the Amiga 600 Vampire II accelerator proved, the FPGA implementation could be anywhere from ten to 50 times faster and cheaper than the original hardware![1] The possibilities are endless with these schematics...

It's worth pointing out that the entire Atari ST has been already done in a single FPGA. See the MiST project: http://harbaum.org/till/mist/index.shtml http://harbaum.org/till/mist/index.shtml I'm sure there are things to be learned from the ASIC designs that could improve the GLUE/MMU/Blitter/Shifter etc. VHDL. But they already work really well. The rest of the Atari ST is off the shelf (mostly Motorola) chips.
