That is true. But it's also part of the
challenge. The even harder
part is to get someone to pay you to reverse engineer an obsolete
computer. Not many of us can afford to do it for fun. Although we
will try.
Is this aimed at me :-). All I'll say is that I wish I could find someone
to pay me to do that...
On the other hand, now that people have a handful
of common platforms, much
more
sophisticated software is being written.
Commodity hardware comes with advantages and drawbacks. One advantage
is that it will be a long time before the last ISA graphics card bites
the dust.
Well, given that a CGA card is technically a graphics card, I suspect
it'll be a very long time.. Offical schematics and programing info exist
for that card. The most complicated chip on it (in terms od understanding
it, not transistor count) is a 6845. Making one from scratch using
whatever logic family or FPGA you favour would not be all that hard.
