I recently acquired a M7649 Studio Display that works well, but the upper backlight seems dim, and the power light is blinking a repeating 'short short long' pattern... which seems to be an error code for a failed backlight. Has anyone repaired one of these before? Is this a caps issue, or does...

I have a blueberry clamshell that needs a lid logo (shocking!) --- someone was selling them on Etsy some time ago, but no longer it seems. Does any know where to get these?

Picked up another PB170 very cheap ($15!), sold as non-booting. Turned out to be the Schottky diode D16. These seems to be a pretty common fault, fails shorted. Symptoms are a non-response to power on, and a dead short at the power connector. The same diode on 160/165/180 logic boards is D15. In...

Hey! I'm hoping someone is willing to share some insights for an issue I'm hitting with an internal PB 1xx NodeMCU (8266) wifi modem emulator board I'm fussing with... whenever the board is powered and connected internally, the PB acts possessed. I've got a pcb with the ESP, max3232 and...

Does anyone have recap list for the ADP-17AB PSU? I'm looking specifically for the voltage rating of C303 (the smaller 47µF one on the output side) - the glue was covering the rating and proved impossible to remove without also removing the cap's label... i'm good on the other three.

@dosdude1 recently set up a dial-up ISP (https://dialin.doslabelectronics.com/), which is super cool. I decided to try connecting using my PB180's (running 7.1) internal Global Village modem - I can dial in and connect via PPP (sweet sweet music) but I can't load any websites. So I'm thinking I...

Has anyone replaced the CCFL in a PB180 display? Or done a LED conversion? Mine seems... tired; takes a while to warm up and doesn't ever get that bright. This site seems to have ones that would likely fit (https://www.ccflwarehouse.com/ccfllamps.html), but I'm unsure on sizing. Any have...

Has anyone replaced the caps for the 5120 display? What are the symptoms of these capacitors failing? (I don't think I have any display issues, but I haven't replaced these caps yet and am curious about the real need to do so...)

I'm troubleshooting some power / display issues on a 190cs, and the tech reference refers to a fuse on the logic board to test... but for the life of me I can't locate it. I'm going cross-eyed and beginning to think it doesn't exist. Does anyone happen know if there is a fuse, and where it...

I'm trying to mess around with Apple IP Gateway, but the images supplied at Macintosh Repository (https://www.macintoshrepository.org/9754-apple-ip-gateway-1-0-1), well they're actually just folders... I made images from the folders to run the installer, but the installer tells me the second...

I'm wondering if there's a way to convert Apple II 5.25 images, usually in DOS 3.3 format it seems, to ProDOS or even DiskCopy format in Bernie ][ the Rescue... or is that just nonsense? I guess what I'm asking is if it's possible to get 5.25" images onto 3.5" disks outside of OSGS? (atm my...

Has anyone tried using a 3.6V lithium AA (ER14505) as a replacement for the Plus PRAM? The 4.5V A21PX/523's are rare and expensive in Canada ($22/ea + shipping is the cheapest I can find - unless someone else has a decent source --- they're plentiful and less than 1/2 the price in the US), but I...

I want to replace the power LED on my IIci (it hasn't worked since I got the machine, tested bad, I have another one in there I grabbed from a parts bin but it's crazy bright). I'm shopping on Digikey but I don't know if I should be replacing it with a 5V LED or something else? Can we tell from...

I've got a couple Pluses with Novy Quick30 accelerators up and running with the RailGun driver on 6.0.5, and they're awesome. Goofy fast. HOWEVER AppleTalk (2.0.2) is borked. When the RailGun driver is loaded, file servers don't appear at all. When the booted with extensions off, the file...

I have Plus that is reading steady low voltage - 9.2V and 3.9V - and showing an odd pattern on the screen (see attached). General sequence of events, things to know: - AB was working fine, but caps were older so decided to recap - recapping resulted in flupping, swapped old caps back in but...

I guess this is the right forum for this... I'm wondering if anyone has been able to find or reproduce the black rubber feet for the Portable case - about 2.5" long, 1" wide, and 0.6" high... I have a case missing two such feet.

Aside from what I understand is expected behaviour using one of the cheap 6V/5Ah SLA batteries and the grey 5140 adapter (I know I know), my 5120 has been working well over the past few months, using it on a semi-daily basis, on battery alone as well as with the adapter. Today, when I went to...

I've been using my 5120 on a semi-daily basis for the past few months after a successful repair, overall working great. The battery is one I rebuilt using a 6V/5ah SLA 'brick' UPS replacement battery, and I'm using the 5651 (the 2 amp) adapter (I'm constantly looking for an original 1.5A...

I've got a couple 800k drives that will spin up a known good system disk to the happy mac icon, but then eject the disk. I'm doing my testing on the one that I've recapped, cleaned, lubed, and cleaned the heads (several times), but the behaviour is the same between the two. The upper head...

I'm restoring a Plus that has a 25mHz 68030 / 25mHz 6888 math co-processor upgrade, but there are no identifying marks on it, on either side (well, it's soldered on so I can't see 100% of the underside, but from what I can see there's no labels/writing) - is there a way to tell who made it...
