Simasimac SE/30 - where are the annotated PCB images so I can trace out issues?

[wanderingjew]

Hey all, acquired an SE/30 and after replacing the power supply (the old one was dead, although the motherboard was exceptionally clean), I'm getting a classic Simasimac pattern. This is after recapping the PCB, installing a CR2032 battery adapter, PurpleROM, and four 16Meg RAM SIMMs.

This is not my first rodeo, but I've been googling for a hot minute, and can't readily find the Sprint PCB layout guides anymore. Does anyone have a link to annotated PCB diagrams? I found the schematics, but having something annotated would make this go much, much quicker.

PurpleROM, and four 16Meg RAM SIMMs.

You generally need to have Bank B populated with SIMMs (1MB, 4MB, anything) if you've got 16Meg SIMMs in Bank A.

You mention you have a PurpleROM, is this the same as a BMOW Rominator II? The above rule may not apply if so.
