Talk:Amiga Advanced Graphics Architecture

AA versus AGA?

Do you have a source for saying that AA was a different version of AGA? I've always heard them as being different names for the same chipset - e.g., see [1]. Mdwh 02:45, 12 March 2006 (UTC)[reply]

To all those who want to revert my creation of 'AA chipset' as a separate article from AGA:

AA is different to AGA. The A600 had the AGA chipset. The A1200, A4000 and A4000/030 had AA. I quote from Amiga Format Annual 1993, page 29: "For starters, we would expect the 'double-A' chip set, which has just appeared in Commodore's new Amiga 4000, to filter down to the base model... The new chip set is, in theory, just as cheap as the current one to fit."

From Amiga Format Annual '94 page 74: "The Future Entertainment Show in November 1992 sees the UK launch of the new 32-bit Amiga A1200. It looks like an A600 with the numeric keypad restored. Inside it's a different story altogether. It's faster, more colourful and marks the move into a new era of Amiga technology with the Double-A chipset... The graphics have been considerably advanced with the inclusion of the new Double-A chipset. These add a 256-colour mode and a Super-HAM mode with over a quarter of a million colours on screen. The palette of available colours has moved up from 4,096 to an amazing 16.7 million."

People who say that the A1200 had an 'AGA' chipset are correct if they use the acronym 'AGA' to refer to certain extra capabilities, which represented a clear cutoff between 'old school' and 'new school' around 1993. AA included the AGA capabilities. But it was *not* the same silicon as found in the A600, it had extra modes, and it had twice the bandwidth. If you want to put 'AA chipset' under 'AGA', then I can accept that, but don't just revert it - Richardcavell 05:10, 12 March 2006 (UTC)[reply]
