Yes, tis a pain doing a search for Professional
Graphics Adapter when others (seemingly IBM included)
chose to refer to it as the Controller. I was under
the impression it was referred to as the Options and
Adapters manual or something. I was going to have the
The manul that covers it _is_ the 'Scientific Options and Adapters
Technical Reference' (which also covers the GPIB adapter, Data Aquisition
Adapter, the connector pannel for that, and the professional colour monitor)
An amusing typo (I assume). When I ordered the Options and Adapters
Techrefs from IBM, they could find no refernce to them on their computer
system. I eventually found a 'form number' for them, and attempted to
order them by that. THat they could find (and had stocks of the
appropriate manuals), so I asked them what it was the form number for.
They told me 'Questions and Answers technical references'. Presumably :
Options and Adapters -> O & A -> Q -> A (obvious typo) -> Questions and
Answers
I assume you
realise it does a hardware emulation of
the CGA card (not
including the 100*160 mode?). And that the 'better'
mode is not memory
mapped at all, rather you send commands to the card
to draw lines,
circles, etc.
Better as in the hi-res analog color mode? The CGA
mode on the VM card can accept graphics commands in
BASIC, but at this moment I'm not able to ascertain
whether or not that means it's bit-mappable (sounds
like it though).
