Have too many good programs on WinXp so I duel boot now with Win7 64 bit for games....perfect solution!
Does your antique mainframe have the processing power to actually play this game? That's amazing! I didn't know they made a version that came on hole-punch cards for those old machines.
Personally I bought the 5.25" floppy version for my 80286 with green monochrome monitor. It only plays at 1 frame-per-minute but I find I prefer that to a faster frame rate, really helps when lining up those sniper shots, if you know what I mean. I'm thinkin' about getting a 3DFX card to upgrade my system with too. Might get all the way up to 10 frames per minute that way.
