Ok, didn't get to tear the thing down today to look at the neck-board (I believe its proper name is the IVAD board?). But I thought for completeness I'd work through the service manual's voltage checks in both the 'working' (i.e. CRT came up) state and the 'faulted' (machine powered on, but no...

Seems the tint problem isn't uncommon. For example, https://discussions.apple.com/thread/8000298?sortBy=rank -- which looks identical to mine. I've had my iMac sat running for a few hours and it does develop very quiet 'crackle' sounds. Initially, I thought, "uh-oh... flyback..." But the...

Right! Well, I've got it reassembled as far as needed to power it on. No way I'm putting that tricksy outer shell on until it's working 100%! Results are: No pops, bangs or flames after connecting AC! Does make a high-pitched whine after supplying AC. The whine varies a bit before...

Hi all, I've had my late nan's indigo iMac G3 DV sat disassembled on my office floor for the past 4 years. Like many who have tried to service these old machines, I had the extremely brittle inner bezel crack into a million pieces during disassembly. I managed to catch MacEffects' Kickstarter...

Hello! I’ve had a BlueSCSI v1 fitted in my SE (on System 6.0.8) for a while now, and it’s been great. The other day, I was messing about with MacFlim to play full-screen video on that old machine. It’s surprisingly good! However, the playback kept pausing to buffer. So I thought I’d delve...

Hah! Indeed :) I’ve not given up hope for the other logic board. I’d love to get it working again, and the chances are better now that I have a known-good machine to compare. I dare say that someone with better skills would have it up and running in no time. But I’m treating this as a...

I ended up getting a second machine from eBay and combining the two to get a functioning machine. Without schematics, I lack the skills to trace the fault on the original logic board. But now that I’ve got a working board, I might be able to compare and contrast to find where the issue is...

Seems like I’ve resolved it! I’d neglected to realise that chosen resolutions are reset for each connected display. so, setting it to a low resolution on the monitor which worked did nothing to set a resolution when connected to my OSSC via a KVM. Having set up a VNC server, I could see that...

Excellent -- thank you very much for your help. I'll get ordering!

Here’s an example! I’m struggling to map those ‘series’ values to anything currently available (I’m looking at uk-rs-online.com). Should I worry too much about that, or just go for replacements which are the correct capacitance/voltage and physical size?

Hi all, I'm building a logic board capacitor list for the Gossamer motherboard (beige G3). Now, I usually work on older machines -- this is the first time I've considered replacing SMT caps from the late 1990s. Don't worry -- I've practiced on a junk board (the control board from my old...

Hi! Like a few others, I wanted to make an old mini into a great OS9 machine. Installation went smoothly, temporarily hooked up to my test VGA monitor. But I wanted the machine to be part of my main retro setup — a bunch of machines outputting via a KVM to my OSSC, which upscales and converts...

Excellent — I shall bear that in mind should this machine ever start up reliably!

Whilst I’m waiting for the VRM board caps, I’ve been having a fiddle. The machine was in a state where it did absolutely nothing when power was applied. I noticed a bit of gunk at the top left of the board, near the PSU Type jumper, so I gave it a spray with some IPA to start cleaning. To my...

Stick 4x 1MB SIMMs in there for maximum RAM. It doesn’t seem to care about DRAM speed or parity, so any will do! It’s very common to find machines that have had the right side of the case mutilated to fit a standard PC floppy drive or a Gotek. If you fancy having an internal Gotek drive, I...
