I have an older style LC III case lid that's going to e-cycle if you want it. it's a little yellow but would retrobrite nicely. the RF shield is gone -- it has rusted away along with the LC III underneath it. I think it was stored in a damp location for years. :(  but the top lid looks nice.

The IIfx is out of the retrobrite and looks great.Here is a picture of the II case (with a stealthy IIfx mainboard) and the retrobrited IIfx case next to the slightly yellowed II. so the question, if I'm going to sell one and keep the other, which one to keep? decisions!

Retrobrite is almost done! In the meantime, I cleaned the ROM SIMM on my non-functioning IIfx board and it now boots great consistently. Booyah! Additionally, I found a non-working Mac II with a nice case and have put 1 of the IIfx boards into the case. It's all cleaned up and working well. ...

Many IIfx's have tantalums instead of SMD electrolytic caps except for 2 near the power switch. This is one of those. I only had 2 replace the those 2 leaky caps and used yellow tantalums. The radial caps will get replaced too, but they don't appear to be leaky.

A couple of weeks ago I stumbled onto a big haul of Macs. Most of them were rusted through, but many were quite nice. In amongst them was a IIfx masquerading as a IIx. The case was horrible, but the motherboard looked nice. So I started searching for a replacement case and stumbled on a...

The IIsi needs a monitor that can sync on green. It will not work on a VGA monitor that expects discrete H/V sync signals or composite sync. It will not work with one of those "timings" adapter either. Your best bet is finding a CRT or LCD that can SOG.

On further inspection. UC17 on my IIfx looked suspect. The legs were oxidized and white. So I cleaned them with IPA and then hit each leg with the solder iron to make sure they were connected. Now the IIfx works perfect. So if you have trouble with your IIfx, check the legs on UC17 and make sure...

I have a IIfx board with issues too. It won't soft power (will check R4 out for sure) but does chime when I jump start it. However, all I get is a black screen from both Apple video cards I have. :(  Will need to connect a floppy drive to see if it's even trying to boot or not. R4 on my board...

Yeah, it's very uniform. every via has it. Unfortunately the board does not power on tho. It's always something. :)

I've got this IIfx motherboard that has no battery leakage and all tantalums except for 2 SMDs near the back right of the board. The SMDs show very little sign of leakage. However, on the back of the board, every single via has a blue-green hue consistent with leaky cap corrosion. I cannot find...

Yup, found it in a related post. Thanks for all the tips!

Cool. Guess I'll order replacements and give it a whirl. I was shocked by how much crap was under those. Looks like a few bad traces too. Will tone it out first and patch the traces. Weeeee!

I removed UD13 and UE13 and it was a disaster under there. Do people usually just replace those ICs or is it worth cleaning and putting them back on?

Necro-resurrection but I just finished recapping a dead IIci and it has this exact same problem. +5v on the power header is shorted to ground. C14 is shorted on the + side. I haven't tried forcing the PSU on by shorting pins 9 + 10 when plugged in, maybe I'll give that a try. I've been tracing...

Oh yeah, that would be sweet. I just downloaded and skimmed the PDF. I love this instruction on page 48: "If capacitor C522 is missing, install a new capacitor." My question is, where did C522 go in the first place? :)

Monitor adjusted and the color looks great. Thanks @jessenator!

Yup, I have plastic tools for the job. Hopefully this does the trick. The 13" RGB monitor has such a nice picture -- I'd love to get it looking perfect. Will get to it tomorrow night and report back. Thanks again!

WOW! Excellent! I will give that a try then. If I can get the color adjusted on this, it will be a very nice monitor for use. :) Thanks!

Greetings all - Picked up some Mac stuff and in the pile was a very yellowed AppleColor 13" RGB monitor. The CRT has a very nice, sharp image, with great geometry and brightness, but the screen is shifted red. Check out the attached picture. The desktop is the standard grey pattern. Having...

Received a small lot of 68k Macs and amongst them was a IIcx (the only IIcx) with the CPU removed and a socket in its place with a Daystar adapter board presumably for a DayStar Digital accelerator card (which I did not receive). Having never seen a IIcx in real life, I was surprised to see the...
