I have a nice condition Woz edition IIgs with ROM 01 (342-00770-B) that fails its self test with "System bad 06010000". I understand that means there's a read/write issue to the serial IC. The solder joints of the Zilog SCC looked good under a microscope but I flooded with flux and reflowed...

I might have gone a bit far customizing Kermit. In addition to the green case from @maceffects, I made a custom all green LED clear fan, green HDD LED and today swapped in a green phosphor CRT from a IIc monitor. It's hard to capture in photos and videos, but looks a perfect shade of green in...

I recently found this card inside of a battery-bombed SE/30. It appears to be a Sigma Designs Pageview card and has a DB15 connection. Perhaps this can be used with normal Macintosh monitors? Does anyone have info on this card or know where to find drivers for it? I tried mounting the HDD in...

I haven't noticed one around, so here is a map of the Macintosh TV's tuner card. The original caps are electrolytic, but the photo shows them replaced with tantalums. All are size B, but you could probably get away with using size C caps. There are some odd values on this card compared to caps...

I have a PowerBook 180C that does not power on and heats up at the connector. I checked for scorches near the barrel and DC-in board but didn't see anything suspect. I checked the barrel connections and found the tip and sleeve shorted to ground. The insertion detect pin works okay. I removed...

Recreating this post since it was lost to recent site troubles. Like many of you, I've experienced screw bosses on 100 series portables crumble when even a small amount of torque is applied in either direction. @ThisDoesNotCompute posted a great video going over the replacement of the display...

This Classic II has vertical bars with no chime after a recap, rework and washing in an ultrasonic cleaner. The bars are present whether the ROMs are installed or not. The reset button does work. It'll just blip for a moment and display bars again. This board is the 2-ROM version. I've been...

This Classic had Sad Mac error 00000003 00040000. Caps were bad, but the board was in good shape. Replaced the caps all and ran the board through an ultrasonic cleaner. After, it still showed the same error. I replaced and cleaned underneath UH6, but no change. Installing the RAM expansion just...

I have two 512k memory boards. Both pass the startup test in either slot on their own and they also work when installed together in either slot. The device can boot Mac Works or Lisa Office boot disks, but won't boot any diagnostic (either images via FloppyEmu or actual disks). The following...

I've been restoring a Lisa 2 / Mac XL and am having trouble getting it to boot any images on a FloppyEmu. All images except the Mac Works boot image result in error 42. Per the service manual, this indicates "Disk controller timeout". I probed the entire disk controller circuit on the IO...

I've been restoring a rusted out Lisa 2 / Mac XL and just got first signs of life. It's showing a horizontal dashed line. If I remove the memory board, the line becomes less defined. Increasing the brightness makes the line way too bright which makes me think I have a deflection issue. The PSU...

Can someone help confirm the value and type of caps at these locations on the motherboard? The label is tiny but looks like it's 104 25v.  I'm assuming that means 10,000pF (0.01uF) and that this is a non-polar ceramic cap. Is that correct?

As I was stripping down the Mac XL I'm restoring I noticed this wiring harness says 'Prototype'. Curious to know if any production units shipped with a label like this or if it's indicative of the whole unit being a prototype. The rest of the unit seems normal, but I'm new to Lisas so might be...

I'm in the middle of restoring a Mac XL. I didn't see a capacitor map online for these. So here is one  in case its helpful to others. Pardon the cob web filled PSU. I'll be cleaning that :) In addition to these there are some axial electrolytic caps on the CPU / IO boards too. Those are...

Some of my compact Macs are either missing or have corroded case screws. They're weird specs of course, so I couldn't find proper off the shelf replacements. So I did what any sane person would do and had new ones made to spec. These replace the top plastic threading and bottom machine screws...

I'm attempting to restore a Mac XL that suffered some pretty bad rusting. The IO area of the motherboard all needs to be replaced. Does anyone here know what the values of the 8x choke inductors at the mouse connector? Photo

I have a stack of Quantum ProDrive LPS HDDs that have sticky head mechanism bumpers. I previously tried replacing a set with stiff 1/4" water filter tubing. It worked, but was a pain to get over the flanges. I recently found some cheap silicone tubing on amazon in the exact dimensions as the...

I posted about this on r/VintageApple, but figured you all might appreciate hearing more of the story. Here are some photos, including a couple not in the reddit post. On Tuesday, someone tipped me off about an Apple box sitting out on the curb. They said it looked like something was inside of...

Apple II folks, can you help with this? I have a disk I’m trying to image, but can’t even get it to read. I verified I can read other disks. In the video below is a Fantavision disk that doesn’t read side A, but does read side B. The disk to image doesn’t read at all. It sounds similar (but a...

This IIci speaker is non-functional. A known-good speaker from a SE works okay when attached. Reflowing the joints for the voice coil wires to MLB connection wires didn't help. Neither did spraying the connector with contact cleaner. The voice coil wires seem like they're attached okay. Is there...
