Title: Bank switching / stacked eeproms (visual confirmation)
Post by: Hoffy84 on September 03, 2022, 03:51:31 am
Do I have this right on the yellow highlighted portions? Starting to go cross-eyed looking at schematics, and trying to figure out the best wiring scheme in an array. - Thanks!

That works.

Typo A1 on 2764?

Yes, that way you get 4 banks to work with.

I assume you checked the datasheets for the pinouts, and that the A1 (A12) error Terry Bites mentioned is indeed a typo. 30 years ago I would have been able to draw them from the top of my head, but now I have to get the datasheets to verify it :)

Thanks guys! Yes, that's combination good ol' Excel auto-filling, and me being up past my bed-time. Appreciate the feedback. I have corrected the photo in the OP for prosperity.
