Re: Speeding up the 9100...

The Amiga AdSpeed would be an interesting experiment. Its a 14MHz 68000 with a tiny CPU cache which iirc had to be enabled in software so in the 9100 it would be inactive. It supposedly had incompatibilities with certain hard drive interfaces so that could be a dealbreaker here.

I suppose you could find one of the 68020/68020 ->68000 adapters with onboard 32 bit RAM but IMHO that probably wouldn't work in a 9100 without major hacking. I had a Microbotics VXL-30 w/o the 32 bit RAM and the improvement was minimal over stock in my Amiga 500.

Subject: [Techtoolslist] Speeding up the 9100...
 

A few people have noted how much slower the 9100 is than the 9100FT, so
it got me to wondering what might be done to improve things.

First of all the 68010 CPU is pin for pin compatible upgrade and
apparently Atari ST and Amiga folks used to replace the 68000 with the
slightly faster 68010 (around 10% improvement or more - some code
restrictions that may or may not matter).

Second, the 68000 had clock speeds up to 16.67 (the 9100 uses 8mHz) so
I'm curious if a little bit of wiring mods might get a gain there.

Mostly I'm throwing these ideas out there in the hope that someone will
dig further and may actually have some results, I'm a bit busy right now
with business stuff...

Discussion?
