Some bodging to rectify my fuckup and...
The MiSCUSI (#Apple2 #SCSI card) works!!!

Which means that I just need some minor rerouting and I can get ready for a rev.1 release. And then for a 53C80 (MUCH easier to obtain) release too!

The MiSCUSI and its bigger brother: the FoxSCSI by @DosFox

They're fundamentally the same card.
I have to say, I still like THT cards better for an #apple2 , but the MiSCUSI should be cheaper if someone wants it assembled in fab. Might have to look into replacing the 74LS133. It's expensive.

I've been sad for a long time that the 74LS133 was discontinued. It was great for Apple II cards to detect access to $CFFF to reset their expansion ROM enable flip-flop.

Alibaba *might* sell you small quantities of SN74LS133ML1 in an SMD package, though their listing looks almost identical to the Digikey one. Digikey will sell you 1,010 at ~30c each.
