Sorry... It took a bit. I was quite surprised to see eetools website was gone. Maybe I should have checked for the software download before moving my burner to a different machine. If anyone needs a copy of eetools Maxloader (topmax, chipmax, etc) let me know. Here is the copy of the NEC rom...

There might be someone with a different method, but these are the methods that have worked for me. You could try soaking the pot in isopropyl if you don't want to take it apart (or it isn't easily taken apart). Just try to make sure the residue makes its way out of the pot when removing it...

This is usually caused by the shaft grease solidifying. I've used a couple of methods/ chemicals to fix this depending on how bad it is and the type of potentiometer. You need to take the pot apart to clean it properly. Sometimes, a q-tip or pipe cleaner and isopropyl is enough. Sometimes, I...

Lol. I picked this up a couple of weeks ago and thought someone had just labeled it after they purchased it. Not sure who's idea at Apple this was, but yeah... Pretty bad!

Not sure if you have this image or not, but I got a PrecisionColor XP card not too long ago with a NEC rom on it (27c256). It boots with an NEC splash screen. Not sure if it's's common or not, so I thought I'd ask. I can send you a copy if you need it.

Great work and video! Awesome that it worked first try!!!

Awesome for sure!!! Thanks for the detailed write up! It's definitely on the to-do list now!

I've saved a lot of tubes with a tube rejuvenator. Some have nearly perfect guns when your done, some don't. It all depends on how 'hard' you have to hit them to clean them (i.e., how bad they are). I will say this... Older tubes are better candidates for rejuvenating. They made electron guns...

I can look at my spare chassis a little later and make you a list. There are quite a few caps in the neckboard as well. I ended up replacing them, but I didn't see any bad. Also... It's not a job for the meek. I had to pull one of the 90-degree pcbs to cap it. It was an absolute dog to...

I just got done rebuilding one. Picked one up at vcfwest off the free pile. I recapped it, but had to spend some time finding a new flyback for it. I was able to find a complete chassis on eBay, so I have 2 chassis now. Both chassis had bad caps in the smps supply, so that could be part of...

I was looking over the results in the github and noticed you needed to verify readings with the new code on a number of machines. I have a number of the machines on that list. Would you like me to retest them for you? And if so which version of Asc would you like me to use?

Thats a pretty good looking donor board. I'd bet you can save everything on it (even the fpu). I'd replace the 258's and the 161's just for peace of mind. A new rom socket, a processor socket, new caps, and Bob's your uncle! The caveat being... it's a lot easier to use new parts since the...

Naw! Any time you need a test, I'm down to help. Any reason to turn a Mac on is a good reason. 😁 Asc version 6 (se/30 version). 4 runs.

Here are 4 tests with the new app (se/30 ver 3).

Original version 3 (non se/30 specific) reports (multiple runs) (1 1),(1,1),(0 0) (5 5), 1 (1 1),(1,1),(0 0) (2 2), 1 (1 1),(2,1),(0 0) (4 4), 1 (1 1),(1,1),(0 0) (2 2), 1 (1 1),(1,1),(0 0) (4 4), 1 (1 1),(1,1),(0 0) (3 3), 1 And another wrench... (2 2),(1,1),(0 0) (1 1), 1 (Was moving the mouse...
