    Default Pitney-Bowes 286? Laptop thing key remapping

    Just got this very odd Pitney Bowes laptop sort of thing that I believe was used for making shipping labels and such. I think it's a 286 with 1mb ram, and it can boot from floppy. The issue I'm having is with the keyboard. It was never intended to be used as anything but for shipping labels or whatever, and it doesn't have a "ctrl" or a ":" key. Is there a way to remap the keyboard? I'd like to use one of the program-specific keys in their place that aren't used in dos.

    Write a TSR and you can do whatever you like with the key mapping.

    No problem in Windows but I'm not familiar with anything in DOS.

    DOS get its keystroke codes from the BIOS tables. You could modify those to generate whatever you wanted--or write a TSR to hook IRQ 9 and modify things from there.

    I'll do some research on TSR's, I've never written one before but I'll definitely give it a shot

    Here's an example that maps the keyboard to dvorak layout

    It's for a PC/XT, but the the general principle is the same--you may be able to get by with modifying only the key table.

    SIMTEL20 is your friend for these low-level things involving old systems.

    I'm trying to use that basic code as a template but it crashes because the computer is an IBM compatible but different than the original IBM bios. I believe the bios is in a slightly different location or something along those lines

    Could be; try trapping INT 16h and modifying the return in AX; should allow most things to run.
