Speed comparisons A500 etc.

Hi
In using just Workbench, what speed difference do you notice when:
a) Adding fast memory
b) a 14mhz 68000 plus fast memory
Also is there much difference between a 68020 and 68030 when just using Workbench and loading games.

Fast ram is a very small boost on a 7 MHz 68000 Amiga, but a very welcome one.

Regarding the 68020/030...this will mostly depend on clock speed. But any Amiga with a 68020 is a huge improvement in Workbench and loading times over a 68000 with fast ram. So for comfortable Workbench use, I have to recommend a 68020 or above.

not to hijack the tread. but i am in a bit of the same situation. i have a beloved derringer 030 (50mhz) and i really love the speed and the 32mb ram it adds. however. i use the trumphcard sidecar expansion. with a outdated scsi controller and a dying hdd. and i have tried all my scsi drive. but the controller wont recognize them. in another tread im told the controller wont accept any disk larger than 300~ 500mb. my smallest drive is 1 gig. and the sidecar is annoyingly large.
Is there any ide controller made for the internal cpu slot that is compatible with accelerators?

As for the tread. the derringer performs really well in the 500+.
i dont remember the number in my head. but the graph in sysinfo is close to the performance of an a1200 with blizzard 1230.

Now my a500+ is picked appart in bits and pieces for upgrading and fixing the battery leakage on the main board. it is stopped. and i hope to add a battery of the newer coin style. (have some schematics to work with..)
And i want to hack the derringer to accept 128mb ram

But my main interest is to find a ide controller that can sit between the derringer and the cpu slot... anyone got any clues?

Have looked into IDE68K?

It seems that no one has tested this with the Derringer, so there would be no guarantee that it would work in your config. They're for sale on amibay (or were last year at least).
