Rather than trying to
acquire a keyboard and monitor I'm wondering if anyone has tried to
replace the boot ROMs to allow either OS/8 or OS/278 to boot using a
serial terminal connected to the serial port. Is that even possible?
I haven't tried it, but AFAIK, all of that style of DECmates (II, III, require a composite monitor (VR201) and an
LK201-protocol keyboard.
I think it is probably possible, but it is just too much easier to get a
keyboard and a monitor. There is arcane knowledge in the making of the boot
ROMs :-).
There is a keyboard (unbid upon) for $10+$10(shipping) on eBay as I write
this.
I also seem to recall finding a description of the pinout info needed to
connect a monitor somewhere on the net.
