I have a Rev A Thunder 24 that is dead. No output of any kind. I'd like to try to repair this, but I'm not sure where to even start. Does anyone have any suggestions or info on what I should look for? I have an old 20mhz scope and a meter. Might have an old logic probe around here somewhere...

I picked up a Thunder 24 rev A card from eBay. Seller said it might be missing a cap on the back side. Got it today and the missing part appears to be an inductor. Just above the left side of the the three rows of pins in this pic are two grey inductors labeled L2 and L4. On my card, L4 is...

I recently picked up an Astec AA13800 power supply. Seemed to be working but the -12 volt rail was -9.8 volts. I re-capped it and the negative 12 volt rail is still -9.8 volts. Doesn't seem right, but I don't another unit to check against. Does anyone have one of these units and if so, could...

I have an early 2009 Mac Mini 2.0Ghz, core Duo.  It's running El Capitan 10.11 right now, but I'm thinking of updating to Sierra 10.12.  Problem is, the Wifi card is going to stop working.  I have one of the unsupported Broadcom  BCM4321 WiFii cards in it. The ID of the card is (0x14E4, 0x90) I...

I've seen these Mac II Bus Master Cards pop up on eBay, and wondered what this card would be used for.  I never saw one of these cards in any Mac II I ever worked on, so when were they typically used?  AFAIK, bus mastering had to do with multiple devices on the bus staring DMA transactions /...

I have the original extended keyboard for my Mac IIx. All the keys are good, but I can't figure out how to turn on the Num Lock or Scroll Lock and get the light to come on... I've tried a bunch of combinations with the shift, option and command keys. The LED's a good.  What are the key...

I'm looking for the settings for a 3 pin jumper next to the 80287 math co-processor socket. It is labeled J4. My guess is it enables the co-processor. I have a 80287 in mine but I'm not sure how to tell if it is being recognized.

Has anyone recapped the Sony PSU in a Mac II /IIx?  I'm looking for a cap list. Couldn't find one anywhere. If not, I'll put a list together and post here.

Added a Mac IIx to the collection. I haven't  got it yet, but I'll post some pics when it comes in. As far as I can tell, it's all there except a hard drive. It's going to need some work.

I have a Spectrum 24/III with the daughter card. It's installed in a IIci, with a Daystar Turbo 040. I'm running 7.1.1 on the IIci. With the acceleration ON, I get a corrupted display when scrolling the contents of a window. I've tried turning off Virtual Memory, and I don't have a ton of...

Is it even possible that a Orange Micro Mac 286 could work in a 7100? I'm thinking No, as the drivers probably won't work under 7.1.2 and up.

I have one of each of these super drives-- UJ-815-C, UJ-825-C. One's from a Powerbook G4, and the other from a G5.  I also have a 50 to 40 pin adapter. I'm guessing either one would work, but I read that these drives are set to master and you need to set the hard drive to slave. I read...

I've been working on this one for a while-- about 5 months I think. A Mac IIci desktop publishing system. The IIci is 100 percent recapped including the PSU. It has 68MB RAM, SCSI2SD, A Supermac Spectrum 24 III video card and an Apple PC Floppy card. It also has a Daystar Turbo 040 Card...

I'm working on a LC575 board-- recapped it and reworked an overclock section. It had been running at 43Mhz for about ten years. It's running at 33Mhz right now and there's still no sound after the recap.  I found a bad trace from C4 to U1 was well. Had to re-flow a leg on U1. If I plug in a...

I have my Laserwriter II NTX up and running -- I've tried several NOS toners and every one ghost prints. I checked a printout and the ghosting is there before it hits the fuser, so I am fairly certain it's the toner cartridge. I'm thinking that at this point every NOS toner (HP92295A, or Canon...

Picked up a Laserjet II ntx-- Powers on, then displays two red flashing LEDS, (Paper Jam and Paper Out) When it powers up, I can hear a click then a second click the printer goes through the warm up and then shows the error I know the fuser heat bulb is good. I'm wondering if the printer is...

That I found on the side of the road.  That brought me here in 2014, looking for info on the problems with it. So I started hanging out and reading here, and I ended up with this... How does this happen? :) G4 Cube, 1.5GB RAM, 120MB Drive. Modded with Dual G4-500's, a Radeon 7500 and a fan...

Has anyone replaced the glide strips on the bottom of an ADB mouse?  What kind of material did you use?

My Powerbook 540 is currently running a fresh install of 7.1.1 --  Are there any good reasons / PB specific fixes/ advantages to move up to a later version?   I kind of like 7.1 but don't know if it's worth moving to 7.6.1.

Is there any reason why a 40 PIN to 50 PIN SCSI adapter cable would not work with a SCSI2SD and a Powerbook 540? AFAIK, Both are SE SCSI.  I looked at the pinouts of the 40 pin connector on the IBM drive and a 50 pin SCSI interface and made this table. I'm thinking of putting something together...
