I can get my hands on a 486DX66 with 16 meg ram 400meg hard drive If this is what you want, i will play it against one of my faster machines? Or just test out nps or epd or??????????? It used to play a good game with Genius 2,3,5. Any of these, wow just remembered Fritz 1,2,3. And I think I still have a copy of Early Hiarcs? Wow my memory is remembering old progs. How about Colossus, still got that on disk! Is there enough oldies but goodies here for you?? Excuse me i have remembered where colossus is and I am going to put it on the amd 400, it should be a blast. I first ran this on a sinclair spectrm 48k at 2Mhz It used to blast thru 170 positions a second, give or take a bit? Infact still got the speccy? Boy, that is old Chris Taylor Notts England
