- This is really strange. For some strange reason whenever a debate is put forth
- on the Amiga vs. IBM/clones, prices on both sides tend to always either rise
- sharply or drop steeply. The truth is that the 386SX cards for the Amiga can
- be had for very slightly under $300. There is no such thing as an $800
- bridgeboard.... That would be ridiculous when you could get an entire IBM
- system for that much. And under $1600 for a 486/50? I've yet to see prices
- that low for any 50mhz machine, let alone a 486 w/80meg... Most of the
- 486's i've seen go for CHEAPLY around this much for a 486SX machine.

- Actually, the Amiga has been revamped. In September, Commodore released the
- AGA series of Amigas (Advanced Graphics Architecture), a 32 bit chipset that
- includes resolutions up to 1024x748 and up to 256,000+ colors in any
- resolution (from a 16.8 million color palette). It also has some VGA-compat.
- modes as well. This is a 32bit chipset featuring 24bit color graphics.
-
- The low-end of these new Amiga's is the Amiga 1200, which goes for $599 MSRP.
- (don't know the actual retail price yet). This is a 16.x mhz 68020 machine.
- The Amiga 4000/040 is a 25mhz 68040 machine.
