Hi all, I'm restoring a 128k with a Levco Monster Mac board in it. I cleaned everything up, serviced the floppy, and replaced a burnt plug on the analog board, along with a burnt Rifa cap. Everything seems to work but I'm getting these weird staticky artifacts on the screen. Has anyone seen...

I'm recapping a 128k analog board so I bought the 3 extra caps from Console5. The film cap at C38 is burnt so I figured I'd replace that and C33 and C37 too.

Can anyone point me to the correct part on Digikey or Mouser or even Console5 for this part at L2 on a 128k Analog board? It's right next to a power plug that fried and melted this one.

I have a Mac II with an upgraded PMMU and 20MBs of RAM. I pulled it out of my display cabinet to replace the soldered on batteries with a battery holder and noticed a resistor soldered in the J2 position. Does anyone know what that's for? Here's some pics:

Can I attach an external LED to my BlueSCSI v1.0-c? If so, which 2 posts do I attach it to?

I have an SE/30 that had been converted from an SE. I'm assuming the chassis was upgraded as well to accomodate a PDS card. Unfortunately, the part of the chassis that allows for a bracket to be attached aligning with the windowed opening on the back of the Mac is not there. I can't take the one...

I bought a few of the excellent external battery holders from @Ron's Computer Videos at VCF East a few weeks ago. After recapping my SE/30's analog board I decided to try one out. Because I prefer to keep vintage gear original and intact, I made a proxy battery that fits the stock battery holder...

Recapping my SE with a cap list from @JDW. They sent me 2 axial caps for C11 aand C18 that I've never seen before. I think it's a "Vishay" cap. I'm not sure which side is neg- or pos+. I googled it and got only one hit from reddit . I don't really trust Reddit advice much though so asking...

I'm restoring my SE/30 that was an SE conversion and the fan is super noisy. I pulled a quiet fan out of an SE parts machine but I discovered that the noisy fan has wires and the other one has 2 terminals sticking out the back. It looks like the analog board has a place to solder in a fan with...

Should I just replace the connectors or should I try to determine the root cause? And if so, how?

I have a stock Color Classic that was recapped with tantalums years ago. It has worked great for over 5 years. When I booted up today, the screen was tinted purple. When opening windows and checking out settings, it went back to normal color but then eventully went to purple again. It seems to...

I'm trying to adjust the alignment on my SE/30 monitor and having a hard time finding the 2.5mm nylon hex key that fits in the monitor adjustment pots on the analog board. Anyone know where they are available? I see the kits on Amazon but they don't appear to a have a hex key and that's really...

I found it in a box with a disassembled IIci PSU. Is it part of the PSU?

I have an SE with the soldered on black battery and I want to convert over to a standard holder. THIS ONE is out of stock, and with the state of supply chains right now it could be months. Does anyone know of another one that would fit? Maybe from Amazon or something where shipping isn't $10?

I ordered a 296-33968-5-ND SN74LS166AD from Digi-key to replace my UE8 chip in my SE/30. When I look at the backorder status, it says March 2023! Wow! Is there another chip that will work? Does anyone have one they want to sell? I can confirm that this chip is too big: 296-SN74LS166ANSRCT-ND...

I've used this microscope a few times now and found it annoying that the surface plate wasn't large enough to hold even a compact Mac logic board. So I took a few measurements and made a slip-on surface plate out of foam core and stick-on cork board from the dollar store. After making that and...

I have a Mac IIci that was having sound issues (really quiet, could hardly hear it) so I recapped it last night (while watching Mac84's live cast). Today I put it back together with only four 1 MB chips in bank A and left out the cache card and battery and left the top off the case. I hooked it...

Any ideas? I didn't replace the axials because they still look good. I have a working SE, can I put the SE/30 board in the SE to see if it works there? Are they interchangeable?

I installed this card in my G3 233 running OS 8.6. I downloaded Firewire 2.3.3.smi and Firewire 2.5.smi from MG and both were corrupt or something so I found another version of Firewire 2.3.3.smi that worked. I plugged in a WD 500GB firewire drive that works on my G4 flat panel running OS 9.1...
