- Re: 8-24GC strikes again...

- Well I have reiterated this several times, but here it is again:
-
- The original 8*24GC with system 6.x provided the promised acceleration (2
- to 5 times)
- at both 8bit and 24bit depth on a IIci with the 13"monitor. It was
- somewhat instable
- with certain applcations but considering the first generation software
- (i.e. cdev) this
- could be considered to be fixed in the next release.
-
- enter system 7 (which I love & need)
-
- the old cdev was incompatible, a fix was promised, it arrived 6 months
- after system 7.
- There was however a catch: the new cdev DISABLED the caches in the 68030,
- resulting in
- an overall slower performance of the machine. 5 months later (approx.)
- there was another
- fix: Now the caches work. Based on this software and the old ROMs I can
- now say the
- 8*24GC is compatible with system 7, although some apps seem to crash more
- often with the
- accelerator turned on (e.g THINK Pascal). The acceleration is hardly
- noticeable in 8 bit
- mode, it is evident in 24bit mode but never reaches the speed it had
- under system 6.
- (This i not a flame on system 7).
-
- Now the great catch for me: the 8*24GC acceleration is NOT compatible
- with the Quadras,
- nor with A/UX, both of which I have to switch to before the end of the
- year.
- In my opinion, in the current config. the 8*24GC offers the worst
- price/performance
- ratio of any Apple product I know.
