Sorry, but 1024x786 is about (exactly) 2Mb, so there's absolutely no problem in using 24 bitplanes. This will fit very nicely in a somewhat upgraded A3000 (or A2000/500 for that matter). >"24 bit graphics" does not imply 24 bit planes. I'm sure someone will Yes it does. >correct me if I'm wrong, but I think that with normal 24 bit graphics >boards, they allow you to choose 256 colours (8 bitplanes) from a >palatte of 16 million (approx. 2^24). Nope, those are 8-bit boards. VGA is also an 8-bit standard, although it has an palette of 18-bit (262144 colours) >-- Frank McPherson INTERNET : emcphers@fox.cs.vt.edu -- >-- AmigaUUCP : uunet!vtserf!morpheus!frank -- Bye Arno. -- Arno Griffioen | Commodore Nederland B.V.
