If you get to the point where you need PROMs programmed for it (containing the operating sytem / monitor) drop me a PM as I have the code for both PROMs - for the revised / updated version of the monitor - in hex file format.

I also have a programmer which can programme those PROMs, should you need that done, although you would need to provide the actual PROMs as I don't have any spare. I think they - or pin-equivalent devices - are still not too hard to find.

Note they have to be 'new' never-used blanks as they are one-shot fusible-link PROMS. Second-hand / used ones can't be erased and reprogrammed.
