- I am using an 8xj on my IIcx, and have had no compatibility problems.
- However, I haven't tried installing the RadiusWare extensions (which kick in
- the acceleration) in my A/UX system folder, and I don't think that works (the
- manual says it doesn't, but the manual doesn't mention any A/UX above 2.01).
- I do have it installed in my normal boot Mac system folder, (with acceleration
- enabled) and this causes no problems.
-
- You need version 1.31 ROMS for A/UX compatibility (the Radius guy said
- some old stock may have older ROMS, upgrading is free).
-
- By the way, does anyone know what form the "acceleration" takes? It seems to
- me that it only helps when moving blocks of pixels around on the screen. Do
- they patch CopyBits or something?
