Some time ago already I had the chance to get my hands on a Radius-made Nubus adapter for the IIsi. (thanks again to @maceffects)
We discovered that this one actually works in the SE/30 so we reverse engineered it. The only technical drawback using this design is that Nubus cards will run at 8MHz in the SE/30 instead of 10MHz that it should be running at.
Most cards I tested did not care about that though.
Space constraints inside the SE/30 impose a few more drawbacks when it comes to using the cards internally:
-HDD has to be moved out of its original spot
-one mounting tab on the chassis has to be bend out of the way, because the solder points for the Nubus socket would be getting in the way
-no 12" cards (obvioulsy)
-access slot does not line up 100% but should be ok for most cards
Good things:
-enough space between Nubus card and floppy drive for a SCSI2SD
-enough space for IIci accelerator slot as well as another PDS passthrough
What are everyones thoughts?
Better make it an external Nubus breakout-box kind of thing and just run the bare Nubus signals through a (as short as possible) IDC cable to an external box with a separate power supply?
It should be possible to modify the design to use all 3 existing slot IDs which would open up the possibility for three Nubus cards in a box.
