Today, the Duo 250.

Over half an hour of work for it to still look like crap. I hate decayed PVA.

Slowly working thru every bad panel I neglected for the last while. All 2 PB500s not in storage sorted, pending arrival of new film. One basic 520 left (stored)

Small wins. 630 boards work, my own standing-water one having come back after reworking a clockgen, video spotty. Quadra 800 now gets a good chime after removing the onboard 8MB and patching traces, needs new DSubs. 601 upgrade needed work but seems to now be ok. Trayloader G3 board repaired, pending tests. A few laptops in storage have degraded. Found a (reluctant) A1138 I didn't recall, too.

Everything went wrong today. PB180 died again, PB100 #2 has lost a pin on the video chip (stuck at 5V) and is therefore also dead until I swap that out, and a 6360 board I'd traded for arrived with extensive battery damage, incurred in the almost 3 years it sat waiting for the guy to send it my way. No surgery is gonna fix how bad that is, I think. Sigh.

After an extended 15h run, the daily use 180 found it appropriate to scare me by hanging with a garbled screen and buzzing ominously after the boot chime. Sorted by cleaning some factory-original flux crap from the lower. Bleeeeeeeech.

"I like bad boys"
"well I don't put caps back in when testing my machines"

Now this heap of junk just needs new polarizer. Ugh.

Under the knife today: a Duo 230. Y'all should be glad 68kmla is not smellavision-enabled

Interesting copper over-etch defect.

Today's victim is one of the PBD280C I recently picked up. Selftappers in threaded inserts, missing screws, inserts ripped from case, hotglue everywhere, broken connectors and switches, broken flip foot... I tore everything apart, cleaned and melted back together what I could. Display has bad polarizer, with which I'll deal later, maybe. Continues.

Battery-bombed PB180 guts somewhat fixed. Lower board still bad, main 5V_SH regulator won't come on. Upper board tests fine on my good 180. Battery connector area, DFAC and surrounding area on the lower are the worst-looking parts.

CC and Classic from a Twin Cities computer club/hackerspace fixed. The CC just needed a clean and recap, the Classic had been recapped but was run with electrolyte still on the board, which ruined that. Bad couple of spares sourced, one clean board made from all spares and returned to club. junk parts kept to eventually do something with.

Got a mangy PowerBook 100. All cleaned and recapped, works well now, using the HDD from the Duo 250 since that has bad tunnel vision I currently don't have the time to treat. This had had the trackball PCB worn thru, and was coated in nicotine tar.

Was given a Classic II board. Broken slot removed for later replacement. Recapped it with new junk that was sitting at the bottom of a decommissioned pick and place. No real plans for it yet.

And also a 520, which needed some fixing. Both are in pretty decent shape, as far as 500 series machines go.
