Has anyone successfully repaired a G3 Kanga with the dreadful glass break crash sound? I have one where it chimes before the glass break. If it's bad onboard ram or cache memory, is it going to be easy to replace?

Is anyone able to get their Radius Rocket to work with a Macintosh IIX with 32-bit addressing? If I turn on 32-bit addressing with any amount of ram (tried 32MB, 128MB, 20MB) then it will freeze on the "Welcome to Macintosh" Logo after a reboot (this is after the Rocket Radius logo) It works...

Have a 840av that is already recapped with red polymer caps. Sound from the headphones jack work just fine but onboard speaker is intermittent. Sometimes it works and is loud, but most of the times it's extremely faint or nothing at all. I would assume this is a bad c48 from bomarc's...

Trying to isolate a problem on a potentially fried IO floppy controller, does anyone know if the Lisa will return error 57 without the "Lite" Interface Card plugged in? Mine is returning the error without the interface card, or with the interface card + floppyemu. But no error with original...

Recently ordered an esprofile internal from juicycrumb and plugged into my lisa from the widget data port. Since my lisa didn't come with a widget power port I powered the board using a micro USB cable on the ESP32. It didn't work. Initially the lights turned on on the esprofile board but went...

Hey all, does anyone know which part of the Lisa video board is responsible for vertical deflection? It worked in the seller's pictures but complete collapse when I turned it on. Probably broken solder joints right? Or which capacitor should be replaced first

Does anyone know where the right most trace beside UA15 and UB15 is supposed to go to? The one corroded with green goo. Is this the trace to adb power or something else?

Video died on a working Macintosh IIx after leaving it on for a while. Turned it off, waited an hour or so, turned it back on and now no video. It still chimes and boots fine, just no video, completely black screen. Tried the same video card on another machine and the card works. Tried another...

I reflowed the ribbon cable right under those lcd caps but that didn't seem to make a difference. I noticed that usually if it's a ribbon issue I should lose 1/4 of the bottom screen right and they'll show up yellowish?

No chime and no sound at all from this LC II even before recap. Getting the following error message when attempting to launch sound settings under MacOS 7.1. Recapped and reflowed UB10 (344S1033A) and results are still the same. Has anyone seen this message before just trying to launch sound...

Was working perfectly. Left it off for 2 days and now it won't boot. First it chimed, turned on with a completely white screen on the CRT but then won't continue further Turned it off, restart and still a white screen but now it's off center Tried a pram reset at boot and now even the crt won't...

Fully recapped and working but this is the second time plugging in a known working portable power adapter (works just fine on other machines) blew the F1 battery fuse. The machine would instantly turn off but can be restarted using power from the power adapter. Just will not turn on with...

Fully recapped! Boot chime plays fine, but as soon as I try to play any sound from the control panel by selecting an alert sound, the system freezes. Initially, I thought this could be caused by new caps shorting to another line underneath, but it still freezes after even after removing the 3x...

The video is bad but other than that everything works! The board itself looks fine and I've swapped the video ROM with a known working se/30 with the same result.

It boots fine with a color classic board so confirmed the analog circuit is working. The original 575 board however doesn't power on, just nothing. Will the LC575 boot with a completely dead PRAM battery?

Came across a duodock that looks to be in good shape from the board but won't take in any laptops, no clicking. Measured voltages across the power supply which seems fine with yellow wire being exactly 5V and blue wire at 21V Any idea why it won't take in a machine?

I recently got a Macintosh 128k that works and boots to the floppy and question mark screen, however Floppy Emu does not work on it. It shows the green light top left but oled screen is blank. Plugged in a known working floppy drive and it will not boot from it either, disk goes in and just...

Really sad that my perfectly working Backlit Macintosh Portable M5126 just died. Really strange about the way it died too. 3 weeks ago I got a new battery from alaska360 and zulusci to replace the old harddrive. It was working just fine on battery (fully charged) and turned on and off without...

Got an old LC II out of storage. It will turn on, the harddrive will spin and sit at white screen for ~30 minutes before the startup chime and boots from the original scsi drive. After that, if I leave the power on, I can reboot and it will chime right away and works perfectly. I thought this...

On a M5126 with backlight. Have a column of keys not working at all: Q W E and I [ENTER] keys. The key and buttons themselves look fine. Does anyone know how to restore/repair these
