I recently got a NCR PC4i in reasonable condition (it even survived shipping).
It's got what looks like an after market graphics card ("Intersil Display Adapter Color III") ... is this card known? Is it just a CGA clone?
The manual (they're available at http://oldcomputers.dyndns.org/public/pub/rechner/ncr/pc4i/manuals/complete_document_set/index.html mentions a BIOS version 3.5 that's supposed to support 1.2MB drives in this XT clone natively with the appropriate controller - so far we've got BIOS versions 2.2 and 2.3 ... are there any more around?
The machine's got a BTX (prestel, ...) card that blew one of its capacitors, but that was to be expected ... I won't be using that any time soon anyway
I'll be fitting the PC4i with a NCR card that was specifically made for NCR's CGA screens and their extra 400 lines mode, and then I'll have to ask someone to help me adjust the display ... at the moment I can see the boot message twice, and it's jittering.
