- But that doesn't mean the Amiga can't use it with a SVGA chip. Even if it
- is not ther, it would take $0.50 worth of parts to add one in.

-
- There IS hardware support of a mouse cursor on any reasonably SVGA
- accelerators. Prices are around $99 (and possibly lower due to RAM prices
- now) The software doesn't use it doesn't mean the hardware is bad.
-
- Come to think of it because of years of bad software, the PC hardware has
- evolved to a state where it actually off load the CPU to make things
- run more smoothly. Who else would make serial chips with 32-bytes or
- 64-bytes worth of FIFO ? These things would make the Amiga fly.

- What stop one from making good API drivers for it ? Isn't that what the
- CyberGfx and RTG is all about ? We won't run VESA BIOS extension anyway.
- I wouldn't mind the VESA bus though as you can easily run it at 40MHz on
- the Walker 030 bus with minimal logic.
-
- The whole arguement boils down to "Just because good SVGA Accelerator are
- not used to their fullest extend doesn't mean someone cannot do that in
- the Amiga". All the current 3rd party Amiga graphics cards uses these
- chips. They are FAST and runs well. The only thing wrong with them is their
- price. That could be fixed and improved very easily with $20 worth of FPGA
- on a daughter expansion on the Walker which could allow one to use VESA
- bus base PC SVGA accelerator cards.
