After leaving my 386SX25 (with non working video in its last months) in 1996 for a Pentium 166, I'm getting back into this era of DOS gaming and general computing tonight. I bought a complete system, saving me weeks/months of hunting from a knowledgeable enthusiast local to me:
486 IBM PS/Valuepoint upgraded to DX2/66, 32 meg RAM, no L2 cache tho
320 MB HD
NEC 15" CRT
3.5 inch disk drive
IBM mouse and keyboard
I mostly have old Mac stuff (68k b&w compacts and laptops) despite being a modern PC user, it's good to plunge right back into the great world of Non-emulated OPL FM synth music sweetness inside dos!
Sound Blaster 16 CT-2940
I don't really care about running the more advanced 3d games, including Doom (I can always emulate, but of course I'll try it). I just want a solid coverage of 1984 - 1994ish dos game coverage.
