I recently met up with a local gentleman and acquired a small trove of Macs in need of work. I had originally responded to his ad looking to pick up the LaserWriter he was offering and wound up striking up a conversation about what all he had - very nice guy, I have to say! I figured that, what...

I've come into possession of an Apple TPD that works (but needs some attention), but I can't get a signal out of any of the Macs I've hooked up to it. Does this thing require a TPD NuBus card to drive regardless of the Mac? My Apple portrait display hooks right up to a IIsi with no issues, for...

Title really says it all - picked up a cheap PB170 that powers up, but gives the boot chime followed by the ol' two sets of error chimes. That's all fine and dandy, except there's also garbage on screen (seen below). I've done some research and checked the PSU (it outputs the correct voltage...

A while back, I acquired a Macintosh Portrait Display that ended up only needing a re-capping to get back in working order. What I did not have, however, was a way to connect it to any of my Macs. After picking up some connectors from Mouser, I set out to make a cable to get my IIsi hooked up to...

After finally getting around to putting a cable together to test out my portrait display, I got it hooked up to my IIsi and... well, it sort of worked. And I stress "sort of." It's displaying an image, but the screen has this sort of pulsing effect, where the image will darken in a wave across...

Woke up yesterday morning and scrolled through marketplace posts on Facebook while enjoying my coffee and came across a post that caught my eye: "Antique Macintosh Computer - Make Offer" I figured, "Oh great, a $1000 Mac Plus that's yellowed to all hell," but was stunned to see an SE form...

So, I know the IIsi and SE/30 have some hardware similarities, but I've been curious about the IIsi PDS/NuBus adapter. I've heard that the adapter can be used in an SE/30 to convert the SE/30 PDS slot to NuBus, but I've never actually heard of anyone doing so successfully. Can that adapter be...

Howdy! I was given an external PowerBook HD that takes a 5-pin DIN power supply. The interior of the case only has two wires coming off the connector, but I can't find any info on this thing. Does anyone with experience know if that's that a 12v or 5v input? For reference, the HD I was given...

I recently picked up a handful of compact Macs, one of which was a Mac Plus. I know it was a Mac Plus because of the form factor (and the Macintosh Plus 1MB sticker on the back), but the faceplate only had the Apple emblem - no "Macintosh Plus" label was present. I'll grab a photo when I get...

I've recently picked up a Portrait Display with no cable, so I have no way to test it. Does anyone know the pinout for the 13w3 connector (found a thread where someone on here had built one, but didn't provide the pinout)? Alternatively, is there anyone on here in the North Texas area that has...

Howdy everyone! I've got an SE/30 that I'd like to try to get A/UX running on at some point, but have no desire to spend the exorbitant prices that rare-as-hens-teeth SE/30 PDS network cards command. I do, however, have an Asante EN/SC SCSI ethernet adapter. Out of curiosity, I read through the...

After working on my IIx to get it up and running, I've been wondering about something. I have a dead, and almost certainly unrepairable, IIfx (there's something screwy going on in the NuBus section, in addition to exploded batteries that I've been fruitlessly repairing damage from) with a 40MHz...

Howdy everyone! I'm looking at a Mac IIx that I've cleaned, recapped, and replaced the batteries on; there appeared to be damage to one trace between a couple of pins on UB2 that I bodged, and that looks like all the visible problems I could find. When powered on, the screen comes up white...

So I got my hands on a 12" RGB monitor, but it does not appear to have much life to it. The font LED comes on, but there seem to be no other signs of life: no degausser hum (though that can vary from monitor to monitor) and no neck glow. C418 looks like it's leaked some fluid but, from what I've...

Howdy, everyone! I just got ahold of a Q950 with a dusty, but other wise good looking, logic board that will not boot. The PSU appears to be putting out the correct voltages when powered on, so I think I can rule that out. Any display I hook up to it registers that a signal is being sent, but...

Alrighty, I'm stumped with this one. I've been using an Apple Multisync Display with an LC that I just recapped that, up until earlier today, was fine. All of a sudden, I get this: Having worked with arcade monitors before, I suspect this is a sync issue. The thing is, if I use a video...

I'm trying to get an LC to boot, but have run into some weirdness. It will not recognize the HD, even though it spins up and I can hear it clicking away, and the floppy will only read a 7.1 install disk. Any other boot or install disk is ejected - 6.0.8, 7.0.1, the Network Access Disk, etc...

Hey everyone, I've been working on my Classic II and have hit a bit of a roadblock. I get a very, very quiet startup chime, but it only gives me the following display: I'm getting 5.00v even and 11.4v off the logic board connector, which seems in spec but may be too low. The thin lines have...

Just replaced my LC040 with a proper 68040 and, good grief, getting the 040 back in the socket was  really difficult. Is it supposed to be that hard to set the CPU back in the socket? It's also not 100% flush with the socket (it's about half the thickness of a credit card between the bottom of...
