I have the Super Mac variant you have but mine has a single NUBUS Slot.Dual PDS does seem more likely I think. Unfortunately the PDS and Cache/Accelerator connectors are identical. Pretty sure bad things happen if you plug one type of card in a slot meant for the other.

I'd LOVE to see detailed pics of that adapter card! The only example I've seen is a crazy/kluge NuBus/Accelerator adapter with the IIci cache conversion section being a second PCB mounted on a standard Apple type NuBus adapter. NuBus/PDS Adapter would be something I don't think I've never seen.I have the Super Mac variant you have but mine has a single NUBUS Slot.
I have this exact card in a box somewhere. It's a pin-thru PDS riser and FPU socket—no frills, no special anything. PDS video cards meant for the IIsi aren't common from the NuBus Era, so 'grats on getting one of them with it. MUCH better than the vampiric on-board video.I picked up a IIsi and found this card inside. It had a video card attached to it with a weird DA-9 connector on it. I’ll show that later.
I’m guessing that this is the Dual PDS adapter.
Can anyone confirm?
That was snapped up pretty quick. If it went for $99 as a BIN, that was a steal for someone.Found a IIsi with this dual PDS card in it on sale now:

It’s called IIsi RAM Muncher. You can also just set the disk cache to 768KB or above and it will achieve the same thing.Definitely look for the system extension (don't remember the name off hand) which plops that on-board memory (usually reserved for display VRAM) into disk cache reserving slightly faster RAM for regular use.
That's the one!It’s called IIsi RAM Muncher.
You and me both! Thanks for that pic, is there a better scan of that page floating around?This is from the DayStar Turbo 040 manual. I have the DualPort adapter pictured in the middle (and the Turbo 040 up top). I have always wanted the NuBus/accelerator adapter pictured at the bottom, but I've never seen one.
I agree!That was snapped up pretty quick. If it went for $99 as a BIN, that was a steal for someone.
