Picasso II vs. 2386SX Bridgeboard

[Motormouth]

So, I can run both, but need to cut my RAM back to 4MB?

Hmmm, I  already installed a switch to flip between 8MB and 6MB for when I want to run the Bridgeboard or not.  Would have to switch between 6MB and 4MB to keep both.

Also, could PC-Task take the place of the Bridgeboard?  Would a 68000 suffice for PC-Task?

Yes this is correct!  you would need to go down to 4 MB of zorro II memory.  
I have had a PII and a bridgeboard running at the same time in the past with no problems.

If you temporarily need 6mb and don't need the PII (go back to ecs/ocs modes), there is a program that came with the PII, I forget what it was called to allow you to use the PII's memory as Zorro II memory.   This way you can have your cake and eat it too.

Oh I forgot one other thing.

Picasso96 needs an 020+ .
consider using the original RTG program picassoRTG that came with PII/+
can be found over at amiga hardware database

http://amiga.resource.cx/exp/picasso2plus

It will not be as compatible with all the picasso96 software out there but it will get 95% of the job done.

I cannot recall if early versions of cybergraphX needed an 020+ or not.
