I have a troublesome Apple Tanzania board out of a StarMax Clone sitting on my desk at the moment
When powered on it boots to a grey screen with the mouse pointer on but never gets any further, the board dose not chime and never attempts to read form the floppy drive
The board has suffered damage from a leaking battery at some point in its life and I have had to patch a number of traces around the ROM's as well as replacing all the data buffers above the ROMS and one of the ROM chips (The current set of ROMS on the board have been tested on annother board and all work fine)
I'm assuming I still have a open trace somewhere (possibly on a inner layer....) but am hoping someone might have a insight into how exactly this board works that might narrow down where exactly I need to look
