So I'm repairing another forum member's SE/30 motherboard. Previously it didn't chime at all and would stay stuck on a grey screen. After the recap, it works - somewhat. It always chimes (boot/death chime) at a very fast rate - probably like 2x-3x the normal speed. Sometimes, it death chimes...

Hi all, As I mentioned in my Conquests thread, I picked up some Apple schematics that might be of interest. Sorry, they are scans of copies so the quality isn't the greatest. I will try and rescan them with my work scanner.

So I picked up a dual SE FDHD with a Total Systems Mercury upgrade (16 MHz 030), and it's having a weird set of problems.  The original motherboard came to me with a shot SCSI bus so for now I decided to move the FDHD roms and upgrade to another SE board I had here.  Right now, there are the...

So I was getting ready to set up my SCSI2SD with my 540c, only to realize that the 540c's HD cable is keyed in a certain way so that nothing can go in pin 17 and the SCSI2SD is not (it doesn't have the missing pin 17 that the CF PowerMonster and other SCSI drives have) For those using SCSI2SDs...

Hi all, I picked up a 512k with the MacMemory Turbo Max upgrade (16 MHz 68000 + internal/external scsi + ram slots + FPU). After some fiddling with it I got it working with the exception of the CPU/FPU - it just detects the original CPU/no FPU. Does anybody know if there's an additional driver...

So I have 3 Classic IIs now, and all of them have issues post a recap of analog and logic boards.  The first one (before I removed the EGRET chip and cleaned underneath it) would do the following: 1) Bars - sometimes if I flicked the switch off/on rapidly at this stage it would boot up...

So I picked up a MacCon card for cheap - however it has a damaged cap on C7.  Does anybody have a value on it? The cap (or whatever remains of it) doesn't have a readable value anymore.

So recently I picked up a 4th PB 100 for $25 shipped, as the screen looked nice and all of my working PB 100s have screen rot. Figured I'd give a crack at actually fixing it before parting it out. Recapped all radial/SMT caps and LCD (also booting from a recapped PSU of the proper voltage) -...

So I've been recapping another MLA board member's Classic I board, and an issue that I've encountered after the recap was finished is the following. This behavior apparently happened beforehand to at a more frequent degree. About every once in a while (1 out of 15 boots or so) I get either the...

So I was recapping yet another PB 100. In the past I didn't seem to have issue with removing this inductor (to make recapping easier) but this time I unfortunately knocked off the leg of this inductor. Going to try and salvage it but can anybody point me to a compatible replacement just in case...

Has anybody had any luck with getting these particular Seagate drives to work on a Mac with built in termination? I have two that refuse to do anything under normal operation (but work fine with an external terminator). I've tried pretty much almost every mixture of termination jumper options...

So I have a IIci here that has a particular issue. It has been recapped. With a known good set of 4 simms (I've tried 1mb and 2mb groups of 4 in bank A) it boots with no chime to a grey screen, then restarts with a chime and death chimes (normal (not slow) speed)/black screen ~5 seconds later. ...

So I picked up a Macintosh II from my friend that has this neat upgrade in it. It's basically a cache upgrade for the II that is supposed to bring the performance up to an IIx. Anybody have a lead on the software (control panel) for it? Unfortunately I can only find mentions of the upgrade in...

Hey all, I recently purchased a Turbo040 + Twinspark adapter (bundled) and I am having weird issues. The Turbo040 seems to work great but I get a "bad F-line instruction" error on about 90% of all of the things I've tried to run.  The SE/30 was recapped by me and had no prior problems before...

So I recapped a IIcx recently (all SMTs and all axials) and it works great, with one exception. All floppy drives behave in the same odd manner.  When I place a floppy, the drive simply whirs. Pretty much sounds like a hard drive spinning up (loudly), and the floppy drive doesn't even seem...

Now that I'm actively collecting again, I figured I'd post an active conquests thread. I've been slowly picking up the majority of one of my good friend's collections for free, with the understanding that I'd help him recap the machines that he is keeping in exchange. Here's what I've picked up...

Hi all, I got these a bit back and was wondering if anybody knew what these cards do. They do not have any external ports, and I can't find much online either. Thank you for any advice as usual!  https://imgur.com/a/vso2PoV -J

I just picked up a complete working NextStation Mono Turbo (slab, monitor, KB, mouse) from the same friend who I picked up quite a few Power Macs and non-working Compacts for free. This cost me $400 though (the most I've paid for a single machine), but I was pretty happy considering that I...

So I picked up a dual floppy SE with a Radius Accelerator 16 and a Radius TPD card (along with the TPD monitor) several weeks ago. Right now it's not booting so I am attempting to check the card to see if it's fitted ok (the two boards seem to be a tight fit currently) The problem is that I...

So I picked up a non-working SE FDHD for free last Sunday as part of a larger free score. I anticipated that it would have the exploding Maxell syndrome and it indeed did. The actual acid damage doesn't seem to be terrible (it did disintegrate one pin on the scsi chip, I have a replacement on...
