That sounds like a worthwhile diversion. I don't know much electronics -
a little rudimentary theory, and then there's this huge gap between that
and "mov eax, ebx". You don't *have* to know electronics, but it might
be nice...

When you get to specifying your new system, give some thought to the
video card. Some manufacturers give out technical specs, some don't. We
can encourage 'em by buying from those that do. I think ATI has recently
started releasing specs... maybe Wolfgang can help us "name names".

When you get back to asm, give us an idea of exactly what kind of Nasm
example you're looking for and can't find. Perhaps we can conspire to
come up with something...

Best,
Frank

all I got so far (4 docs) came from this site:

http://www.x.org/docs/AMD/

almost just ATI-GPU register listings without explanation of how to use...
I still haven't found where the bus-masters on my ATI-cards reside,
perhaps I need to read this books several times ... :)

Well, I suppose examples in Nasm syntax was a little too much to hope
for. :)

Speaking of specsheets (not for video), Debs (no less!) popped up on the
Nasm forum a while back and provided a link to this page:

http://datasheets.chipdb.org/

AMD to ZMD... what in hell is ZMD???

Best,

:) outch. You know I watch NASM with interest,
but I don't have a C-compiler to 'make' the tool ;)

a good link indeed, my regards to Debs.

I never heard ZMD before, the spec is for an UB8001, a true 16 bit
(adress+data bus) MC, perhaps a DDR-clone of an early Zilog Z-8/280.
This datasheet looks somehow heavy dated to me.
