I found this notice on "Atari-Users.net" . Look fascinating. Could this be the answer to our ageing hardware problems? I don't know how far away this guy is from producing something that would usefully connect to peripherals but I'm definitely interested. Living in a small box now.
" SUSKA - a MegaSTE on chip
Instead of a classic software emulator, the German developer Wolfgang Förster has settled for another approach to achieve compatibility with the old Atari 16/32 computer systems. The FPGA chips can be programmed with the language VHDL to recreate digital logic circuits, and Wolfgang has now been able to rebuild a complete Atari MegaSTE in VHDL!
Some have already suggested that SUSKA could be used as a backwards compatibility chip in new Atari hardware (offering near 100% compatibility) or as a portable Atari STE.
