There used to be a little DOS program called 'goslow' which inserted delays into every BIOS call (slowed space invaders to my speed :)). Might be worth a try? Additionally try telling the BIOS setup to put wait states into every memory access and switch off the BIOS in ram option.

LS, I think I solved part of the interfacing problem. With the older software I had (HPLINK.EXE) it was possible from a dos session outside windows98 to display and print files from HP to PC. I did not succeed in file exchange by the drive option. (Until now I did not have the chance to try the in the manual suggested assign drive option (with an older dos)) On ftp://ftp.math.jyu.fi/pub/hpil/ I found software for the HP71 to use the interface card. The software (HPILLINK.EXE)works well from dos outside windows98 and it is now possible to have full access to and from HP71 to PC on my 450 MHz Compaq. The interfacing with HP41 is a bit more cumbersome. By a printing to file option it is possible to upload files from HP41 to PC.
Hope it will help a bit,
