@ MinerAl: Yep, I was as well. "Compact Virtual" would be the key to unlock the SIMMs on all such accelerators.

I imagine CV requires a 68020 with the PMMU upgrade at a minimum, VM doesn't work w/o paged memory capability, IIRC.

I3arana, check to see if you can turn off acceleration while leaving the RAM/VM active on any of the SE/Killy Klip Accelerators.

Then you could consider the upgrade a RAM Disk/VM Co-Processor Card and remain 68000 correct for your Cube! }
