I wish WriteNow was similarly available/supported --- it was probably one of the last major applications written in assembly language (~100,000 lines).

XyWrite is supported in a similar fashion: https://mendelson.org/xywin.html (but I just helped folks use that, never actually found it comfortable myself).

I kind of wish all these small/tight/efficient programs could be gathered up and ported to an optimized OS for the Raspberry Pi....
