As part of my Challenger III cleanup, I dumped the ROMs:
http://filedump.theglitchworks.net/soft ... /osi/roms/
My system is a serial system, so the monitor is the 65A and 68A2. The boot ROM (does it have an OSI official name?) at 0xFF00 supports hard disk booting. This system doesn't have a hard disk ROM, but I believe my other 510 board does. It's still packed from the move. I'll add its ROMs when I dig it out.
Here are the manuals for the 65A monitor (it includes the 65V too, 65A is at the end):

And here's the 68A2 manual:

Very nice. Also, nice writeup of your cleanup of the machine.
