But is it the Rev C board you prefer?
Yes, unless the Rev B board was discounted, then I'd get that. I've seen images of the Rev C board so I know that they're available somewhere.
I already have the W65C256SXB board so I really only want the 816 board as a reference to compare with my own build, including non-BANK 0 memory access. Right now I'm particularly interested in comparing WDC's bank latch implementation against alternatives as I've seen other builds where the 74HC573 proved not fast enough to latch the bank byte. You'd figure a WDC board would get it right, but I guess this post shows that they're about as good as they've always been.

If so, and you end up with a Rev B instead, you could follow Spacecoaster's suggested mod procedure to create your own Rev C -- it doesn't sound too difficult.
Agree, though I'm not sure I'd do the mod to pin 38 of XBUS just for testing.
Edit (3/8/22): I received the Rev C board from WDC via Amazon.
