OK on it being the same algorithm. Then let me rephrase. Are you (or anyone)
aware of any source for programming the 16C74-12C508 using the PC's
LPT port? I've got the programming specs and could try it from scratch
myself but thought there might already be some source out there.

Anyone know of anything? Possibly one of the numerous 16C84 programers
include the PC source?
