OSI did not release the source.  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....
