Just so you all know...
After very limited bodging, I was able to get the #FoxSCSI board (by @DosFox naturally) recognized by the Delta (#apple2 clone) and booting from it using a #BlueSCSI!

Added the resistors and some sockets to the #FoxSCSI, then had to drop to go do some work to prepare for a fair this weekend.

When back, before putting the Apple //e back in storage I tested the GalDisk, MiSCUSI and Tauntingboard for clearance, and luckily no issue (provided straight headers are installed instead of angled, but that was expected).

Still, I decided to tweak the placement of the header in the MiSCUSI to make installation less tight. There's time before the next run, anyway.

Look at what I have on the bench today, thanks to @DosFox !

I can start building his #FoxSCSI card while I wait for the controller to test mine!

This board is a beauty.
