IBM 5150 PC

2009/7/8 Ben <bfranchuk at jetnet.ab.ca>: Several forms, yes - Borland's early versions of TurboPascal, the original UCDS p-System, and so on. Basically, almost any DOS app from up to 1988-1989 or so. When Windows 3 came along and 386s started to get commonplace, some of the high-end DOS apps started gaining 386-specific features, or wouldn't run in a DOS config without 600K or so of conventional memory and some expanded or extended RAM too. That's damned near impossible on an 8086 machine. For instance, Lotus 1-2-3 r3 won't run: it needs a 286 and 1MB of RAM. Even Windows 3.0 in VGA mode won't work - the VGA driver uses 80286 instructions. An NEC V30 chip is a socket-compatible replacement that implements the real-mode 286 instructions, so it will run Win3 in VGA - but that's getting a long way from a standard IBM PC. But most DOS apps that predate Windows 3.0 will work, including umpteen programming languages from QuickBASIC to Turbo Prolog. Just not very fast, that's all. :?) -- Liam Proven ?
