Once upon a time someone I knew in a large 3-letter computer company disassembled OS65-D over a month or two of watching football games on TV. He was the kind of guy who needed to keep his mind busy while watching football..... He eventually got a set of commented source that would reassemble and run, and we were able to add a new printer driver to some jump table. I have no idea if he is still around, and if the source is either. I'll ask about. That disassembled OS65D listing had something to do with a big fight that ended up with the IBM PC having the BIOS LISTING!! in the TechRef. But that's another story....
