cwsdpmi

Provides DPMI services for DOS. A few of the programs listed here require this.

nullpkt

Fakes a Packet Driver. This allows some programs to run even without a real packet driver. (note: works great!)

int5f/TSR

run programs written for the HP 200/LX computer.

htmlc200

Superb HTML-based Calendar Creator. htmlcal.exe /a will generate all 12 months of the current year. Many more options are available via command line switches. Protip: In Linux, rename all filenames in the current directory to lower case (the program outputs filenames in All Caps - a DOS artifact):

rename 'y/A-Z/a-z/' *

I've included here a sample of its 12-month output for 2024 (htmlcal /a) and its original documentation (the document is original - not a word changed; I just stylized it a bit). Direct download here too.
