Thanks! So glad to hear that BOMARC's schematics are problematic.
I know the squiggles are resistors, but the triangles and such leave me baffled.
edit: I bought a book on digital design on a recommendation from
@trag but ALL my books on electronics and the Apple tomes are in a box somewhere and not on my shelves yet after flood remediation.
Anything out there online in the meantime? Heading to work and Google during downtime.
