I thought the rewiring went really well. The PRAM battery clip/holder is due to arrive today but hasn't shown up, so I tried testing it without a battery. I got nothing. No video, no sound. On the positive side, I got no exploding caps, no smoke anywhere, no clicking/squawking power supply...

I found the perfect spot for the C36(+) bodge: the ROM SIMM socket is not populated, and very close to the RAM SIMM, and has two candidate through-holes very near C36. Now.. to craft the wires.

This is looking not-so-bad. Won't be any ugly and electrically iffy-longish rework wires running around the board edges as I feared. Part(polarity) Rework C137(-) Topside bodge to L12 near FD1. Topside bodge to U30 pin 15. C137(+) Topside bodge to C136(-). *Note A C136(+) Topside bodge...

Thanks. I was taking a break and thinking I would continuity-check them tonight or tomorrow - but I need a board vise, third hand, aide, something. Some of these may be "second level" challenges. C137(-)'s loss for example breaks a trace - so I expect it will require at least two bodge wires...

I have a Quadra 605 logic board that lost some solder pads during an aborted recap. Five, possibly six of eleven caps have lost one or both pads. I completed the de-capping and am now assessing whether or not I have the skill to restore the board. I have limited tools and experience with such...

I have a similar Asanté Ethernet, the PDS MCLC, working on System 7.5(.0) over a Cat5 twisted pair 10BaseT cable. It would not auto-negotiate with an unmanaged 10/100/1000 NetGear GS116 ProSafe switch. I was lucky to have another switch on the shelf, a managed NetGear GS308E ProSafe Plus which...

I need more sleep. Apologizing for my last post, which makes little sense. I do use 2MB SIMMS in my Mac LC restores; they give enough 'headroom' as I get the software installed. They are handy, yes. What I brain-farted about was my recent find of a trove of 4MB SIMMs, which for some reason...

I was pondering this question just last week. Firstly, I think for a second floppy connector, you need only clone the existing connector but replace the new connector's enable line with the other enable line. You'd have to (carefully) solder a wire directly to the SWIM to get that signal, as...

I'm restoring two LCIIs and found four working 2MB SIMMs for cheap. Just enough to max them both out. Sort of odd that the only way to max out the LC memory is to waste two whole megabytes. I read somewhere there's a PDS accelerator board that moves the RAM onto the PDS card and can lift that...

Thanks! (I wasn't sure if I needed inductance and capacitance.) Recapping the PSU went smoothly, and it now shows -4.97, 11.99, and 5.10V with the logic board attached. Close enough. Three caps had leaked badly, and one or two others had either leaked or had the leakage of other caps under...

What would constitute a fair test load for the LC II TDK PSU? I want to test an LC II PSU without risking a logic board, or without risking frying a properly repaired PSU with some defective logic board. I've come into a need to repair an LC II PSU (a TDK), but don't want to risk using the...

It helps when the hardware basically throws you the answer. Working while booted from floppy last night when, after a few hours, the HDD spun down. That (dreaded?) descending slide down the scale to silence. I thought, would System 6.0.8 have known to sleep an idle hard drive? I thought not...

Thanks all. Planning to do another round of work on it in a few days. Thought I'd get a list of PSU caps ready and on order, just in case. While I'm ordering, might as well get the logic board caps too, I guess. And I rethought the PSU load theory I had. It's very unlikely I've managed to put...

Hello all. Avid readers may recall I recently repaired an SE FDHD. Along the way, I noticed some infrequent, momentary narrowing of the CRT image, so I recapped the analog board. It seemed to be fixed so I reassembled the case and declared victory. But last night the screen had a period where it...

I just did my first recapping on a Mac SE(/00) analog board, revision C. I rate myself as a hobbyist-level board reworker. I was a little nervous about this, as the system was working almost perfectly before I started. But it wasn't too hard, and the results are well worth it. Advice to other...

I recapped the analog board, and replaced the fan while I had the board out. Along the way I did find one solder bump that looked slightly corroded; I desoldered down to a shiny bare pad and made a fresh connection. No signs of cap leakage or cap bloat. This wasn't very hard. The only challenge...

Hey Berenod - yes, I thought that the CRT jitters might be caps showing their age. I've ordered the replacement parts. I do some PCB rework now and then, but consider myself only a hobbyist, so I'm hoping I can get the old parts off without pulling any traces up in the process. I think it's not...

Again everyone, thanks for the encouragement and info. It kept me going. I found a BinHex file of the complete Zip 4.2 install diskette (kudos: vintageapple dot net). Rather than expand it on a modern system and risk losing resource forks or hitting other translation flaws, I sent it over...

Thanks, everyone, for the advice. Good news: the replacement drive arrived and works well. It's a later model, 50-pin but half-height, not Apple-branded, and it came with 7.5 already on it. It boots fine. Yay; its thinner body will allow more air circulation inside the chassis. The full-height...

Thanks for the idea, dramirez. It's been ages since I was 68k-Mac-savvy and I had forgotten about SCSI Probe. The Mac I am restoring boots from either SuperDrive, so this is a go. I'll see about building a floppy with a runnable app on it later today. I think I have found a 1.44MB DiskCopy image...
