Second Wave"s PCI -> NuBus Expansion Box & Others

If that board says ©1991 it will be very interesting to see if you can get it up and running with the PCI Interface Card. I wouldn't worry too much about getting your money back even if it doesn't work out. Someone with a two or four slot NuBus interface Card will likely want to give it a try.

Thanks for the piccie, I missed your question about interest in documentation. Some closeups of the logic would be really good for checking out the missing IC's function.

The chips next to the bus termination are especially interesting, as well as the DIP switch diagram.

A stack of these boxes filled with Grappler Cards hooked up to a rack full of MoDems in a BBS config makes a world of sense to me. DIO is the only other use I can think of offhand for a multiplexed stack of boxes like this in the six slot IIx/IIfx era.

Interesting question, does anyone know of any 8 bit + software emulators that can do hardware calls across the host's expansion bus?

Click to expand...

not 8 bit, but uae has a iirc warp3d driver called quarktex, which speaks to the real 3d card installed in the pc uae is running on. handy to say the least.

a real 68k amiga with a pcibus and radeon/3dfx card can do 3d with warp3d and rtg.library.as well as some zorro 3d cards.

The SE/30 interface card popped up on ebay

Why in the name of god is there a Dallas RTC?

Not a RTC, just battery backed memory.
