I have some questions regarding MS-DOS and AIX:
What possibilities exist to run MS-DOS programs under AIX
on a RS6000 system?
What MS-DOS emulators are available?
What kind of performance can be expected?
How much installation effort is needed?
Thanks for any information

Yes, if you purchase the PC Simulator product. This product gives you an emulator that is based on the AT (80286 processor) >What MS-DOS emulators are available? See above, runs PC-DOS 3.3 >What kind of performance can be expected? Depends on what the application is. If its a heavy duty number cruncher, then the performance has been quoted at a 16Mhz 80386 (read in one of the trade magazines). If your application is VGA, then the performance is along the lines of a 12Mhz 80286. The difference is that all the display hardware that you get when you buy a VGA card is being emulated in software. >How much installation effort is needed? > Little if any.

If your application is VGA, then the performance is along the This should read if your application makes extensive use of the VGA display hardware, then you will note a drop off in performance. Heavy duty graphics programs will obviously run slower as the software is emulating everything that is on the VGA hardware cards. >lines of a 12Mhz 80286.

When using the Surfer (Golden Software, Golden, CO) contouring package under pcsim the gridding/contouring times suggested (a) an XT with 8087 (b) a 16MHz 80386 without an 80387. Graphics are slow. The 3D color graphics cards seem to be slower than the normal 8-bit color cards. Also, WordPerfect is noticeably slower under pcsim than it is on a 10MHz, 1 wait-state, 80286 (w/ 80287) machine. BTW, a 3D graphics subsytem takes two slots, the ethernet card needs one, and the SCSI controller needs one -- and the model 320 is FULL.
