The problem is that the HP150 is a true MS-DOS machine, but it isn't IBM
compatible.  It supports all the MSDOS INT 21h interface, but it does NOT
support the IBM BIOS (INT 10?) calls.

Since most programs for the PC use BIOS calls to improve performance,
especially for display of text/graphics, they don't run unmodified on the
150.

(I think I may have heard about a BIOS emulator for the 150?  Is this just
my wild imagination or is it real?)
