From: S7YLF4%IRISHMVS.BITNET@WISCVM.WISC.EDU One fine day ago I read something about a chip called (appropriately anthropomorphically) Daphne. I don't know much about the Amiga innards, but I saw something about a different 'halfbrite' graphics mode. Does anyone know anything about it? Also, off on a tangent, why was the Amiga named so? (Do the original designers have a thing for female computers?) nj

The story is that originally the Amiga was called the Amica, which is Latin
for friend, or friendly, but come copywrite time, they found that Amica was
in use, so they changed the name to Amiga. Supposedly they didn't notice
the Spanish connection, but I'm not so sure.
As for Daphne, I too would like to know if, when rev. 6 of the chip is
being produced (probably now), we can get it into our machines. I,
for one, would like to be able to see the extra-half-brite if I'm
developing a program that uses it.perry@atux01.UUCP (P. Kivolowitz) (03/14/86)
At a VMR meeting I attended in Manhatten, it was disclosed that rev 7 daphnes (denises, whatever) will no longer have half brite mode. Some background: Most machines shipped have a rev 5 daphne. Some new machines have rev 6 which can do half brite (64 color, 32 being half the intensity of the other 32). Most people cannot utilize hb mode since they have rev 5 parts. Updating everyone to rev 6 would be exp- ensive. No rev 7 parts have been shipped yet. But will in the future. Bottom line: Don't utilize hb mode in any code you are developing. Could someone from C= confirm this to the net? Although I heard this first hand from a high C= official, I'd like to see this from a second C= source. ---------------------------------------------------------------------- Perry S. Kivolowitz

Will a low level AMIGA source do? We are now to Rev8 on denise's (daphnae's were dropped over a year ago) and the EXTRA_HALFBRITE is still in there. Dale Luck ps: What was the high C= official on? must have been good!

Perhaps he was trying to pacify some Amiga owners to keep them from squawking for upgrades to halfbright for their machines. Personally, I don't mind if C= dosen't want to upgrade for free, I'd PAY to upgrade my machine. If C= setup a denise upgrade mechanism in such a way as to provide some extra revenue (or at least pay for itself) I wouldn't think that would be too bad of an idea (anybody remember the Atari 800 CTIA => GTIA upgrades?

RE:
"We are now to Rev8 on denise's ... and the EXTRA_HALFBRITE
is still in there."
Will it be possible for us to upgrade from rev 5 or whatever? Is the
chip socketed? If it is possible to order the chip, how much is it?
(If I were ever to open up the case, I could answer some of this myself.)
What sort of things are being changed that require new revs???
