Considering the application, it would likely work fine

The way I do it is look at the datasheet and see the recovery raitings, the voltage/current raitings and i use those details as filters to pick a new one on Mouser/Digikey. It is a fast recovery rectifier, aka shottky diode. According to the datasheet, its a 600V 1.8A Shottky. you can probably...

Oh he was at VCFMW, I ran into him a few times, he bounced someone over to me who was having a problem with an Apple II PSU.

I do all of those repairs too, but I only take them on with a case-by-case basis, and I only am able to do that stuff on the weekends. That may or may not be the case for him as well, so he could just be busy.

These boards all need fully resoldered, and fully recapped now. The solder joints have gotten atrocious on these boards. Also de-oxit the middle cable that goes between the front and the middle, which carry the video signals. As well as resoldering all of that. That usually takes care of most...

those white caps always crack. Its a white RIFA. Has to be changed.

Bumping this. I need the same thing, as my machines are missing the battery and battery door. the battery doors are brittle, and having a big hole there just isnt a good look.

Diodes are almost never visual, thats why when i run into weird power supply faults, i grab a DMM and check nearly everything

Bump... Yeah thats the stock ROM. Quickboot from what I saw is a ROM coupled with a PAL which hides the entire Macworks bootstrap inside of it so itll boot from SCSI. Sigma7 made em and apparently no longer sell them. Also didnt pass the torch to anyone else that I can see to keep them going.

Some of them were, yeah. The ones that were traditional IDE, Toshiba was notorious for hardcoding the BIOS to only work with their specific drive bundled with that machine so you need the expansion card which has an XT-IDE to CF solution.

The Toshiba T1XXX line are horrible for pissing capacitors everywhere, eating traces away and even blowing up transistors. I have worked on many. The T1200, and especially the T1200xe is the worst offender. I have a pair of those and I have been unable to repair them. The power supply...

Does anyone happen to know if there is a good color match for the Powerbook 1xx line on 3D printing filament?

I picked up a set of those chips from the Poland auction just to have them on hand for later. I will need to build a programmer eventually.

DosFox finally took the plunge and bought NOS chips, programmed them with the dumps and they do work. He has not provided any more details outside of that yet. Tons of NOS chips are available on ebay, but theres several variations. The specific IC variation has not as of yet been reported. I...

how are you even getting color pictures/screenshots from an SE?
