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!
The prototype board by @DosFox (almost) built and bodged.
It still lacks the LM317 for active termination and it's using an 74S133 in place of an LS (because I was out of those).
@hkz thank you so much for building these prototypes!! I'm glad that it's only a few tweaks to the hardware - I'll release the designs shortly!!
@DosFox it was a pleasure
