I've got a project in the works that would require subscribing
institutions (museums and planetariums, mostly) to purchase an
A2000 with a fair amount of hard disk space (I haven't nailed
it down yet). I'd really like it if these folks could go to
their local Amiga dealer and say "Excuse me, I'd like to buy
a... (looking at sheet of paper) an Amiga 2000HD system..."
(or a 2500) as opposed to having to go here or there and put this
card into that slot... you know how it is with customers. :-)
Unfortunately, my code uses a lot of overscan HAM images (typically
352X480 pixels) and I've heard some bad things recently about the
combination of the 2090A and this video mode. So, like, what's
the poop?
I've read the recent AmigaWhirl article and quite frankly, I don't
think those benchmarks are worth a sack of, ahhh, yams (I mean,
really, this guy was AMAZED that a non-DMA controller could provide
raw transfer rates that are as fast as a DMA controller.) Anyway,
I'm a little hard-pressed to believe that, under severe overscan,
a 2090a writes twice as fast as it reads...but I haven't tried it.
What's the poop?
Thanks.
