Re: Stupid Arduino Tricks

Anyone have a Laserwriter IInt?  It looks like those had an ADB port, and could probably be put into diagnostic mode via the ADB port too.  It looks like those things were basically headless macs.

Re: Stupid Arduino Tricks

I wonder how in-depth these tests get? I had an SE/30 board which I sent back to Uni, that kept giving me sad chimes, or sometimes I would get a good chime then a sad chime. Or a good chime then nothing.

Curious if the diag would spit out the exact bus error...

Re: Stupid Arduino Tricks

You might consider trying to bake the layers of the Macintosh IIsi's PCB inside its actual Power Supply too.: Occasionally the layers of PCBs unfuse and reheating them with a hairdryer on Low Power for about five minutes is just barely enough to coax the layers of PCB into refusing once again too.
