This is more of a documentary attempt to revive a Mac Plus 1Mb. It arrived today and physically is in excellent shape - less horrific smell of cigarettes! First thing was to fix solder points on analog and logic boards. As expected, many had cracks. I did them all though since sometimes the cracks can be microscopic.

But she is a no-go to boot. She beeps but is cut off short of the full tone. The floppy just cycles. If I power it off for a short time, it will beep again then cycle the floppy. I have lots of test parts so I can narrow it down to the component pretty quickly. I have a feeling this will be my first venture into analyzing an analog board!

I will update as I go along.
