I've been looking at this https://github.com/frozen-signal/Apple_IIe_MMU_IOU/blob/master/Schematics/IOU_2.jpg for a good 10 minutes now.
There's a '/R W' signal and an 'R /W' signal. It's not a typo.
Going from one to the other is trivial, of course, but it seems they forgot to put this NOT gate on the schematic. Which makes me worried they might have forgotten something else. Sigh.
