Hi. I'm desperately looking for a source of ROM file for a PDP42V7 PDP (Non- vzb). I think the file I need is 42V73DNCS1 or 42V73CS4AD.
The original ROM was 42V73LA2A, I flashed a file I had in but got blank display, though on board test patterns were fine. Biggest problem I have is that I have to remove the IC to program it.
Any advice?
