I've bought a copy of Dead Mac Scrolls and waiting for delivery.

The "Repair and Upgrade Secrets" seems harder to find, more expensive and fewer pages. Is there stuff in it that I won't find in the Scrolls?

Meantime, by swapping boards and ROMs with a Plus, I'm confident that the 512ke ROM(s) are corrupted, but the analog and logic boards are otherwise functioning OK. Now planning to replace with EPROMs (see other thread)
