Perhaps a tip: the software compiled using Borland's Pascal has a bug that aborts with "Error 200: division by zero" in some Pentium machines. This occurs only in Pentium processors and the cure is a program called "tppatch.exe" (it replaces a specific instruction sequence in the executable). (This problem occurs even if you boot from a DOS 6.2 floppy). May be, the old DOS-based soft for the ALL07 could have a similar problem... I think that he ISA slot in a new Pentium III should be equal to the ISA in a old AT. Regaards, Alejandro.
