Impressive work. Too slow at WordStar to be usable though. "Fast and furious" :-) Close though! Maybe some serious optimizations in his virtual machine can make it fast enough. I'd guess he's straight mapping 8080 instructions to 6309 code. Depending on how he's handling register mapping and whether he's doing any cached code translation versus straight mapping/interpretation there should be thing he can do. Still would be useful for non-interactive programs (like compilers). -- John.
