I have a Macintosh 12" RGB M1296Z that was working properly until the image on the screen became slanted and compressed along the vertical axis. I disassembled the monitor and found three leaking capacitors in what I believe are in the VSync section. I was unable to find a replacement for the...

is it something rare? I'm not in the G3 really ....

two new babies: LC475 + 7200/75 The 475 seems to be pristine!

I bought a Mac IIci with a surprisingly still-working Quantum 230 MB hard drive, and immediately made an image since it had MS Excel and MS Word installed. I recapped the logic board except for the axial capacitors. The PSU works fine and shows no bad capacitors, so I’m leaving it untouched...

Hi everyone, I have an LC II, apparently in good shape — no battery damage, it was stored in a warm, dry place, and there’s no visible corrosion. The absence of the J9 IC seems to be normal in these boards. Pin 117 of the CPU is bent, but there is continuity. However, the capacitors near the...

aplogies, it'sduplicated but .... there is something wrong here....

I was given a Power PC 8600/200. 'm not really passionate about these kinds of machines; they are heavy, the plastic is brittle, they are large and with a questionable design (they are ugly). I did not power it up. I could dissassble it, clean brush, replace caps (even if they look ok), check...

What are the best solutions when doing a bench test on all-in-one Macs? I found the following for the VGA connection: - from ConvertStuffUK for the Classic, SE/30, Plus - the solution from Adrian Black - Guruthree Video Converter - Caymac compact solution For the power supply, I'm thinking of...

This LB is gone, can I save the 8 x 2Mb RAM chips and create a 2MB 72 pins SIMM or a 30 pins SIMM? 2MB is not much, but maybe better than leaving them there. I can't find a PCB GitHub project for this scenario (Yes, I'll remove the CPU)

I connected an LC 475 to a High-Resolution Monochrome Monitor MO400, specified for 640×480. https://lowendmac.com/1989/apple-high-resolution-monochrome-monitor/ The monitor produced an image for about 5 seconds, then emitted a loud crackling noise consistent with high-frequency arcing. I...

Ok, I got a very nice-looking Performa 475 with a network card, HD, VRAM, RAM — but missing the PSU. I temporarily added a known-good PSU from another LC. The capacitors look fine. I even removed one to check underneath, and it confirmed no visible leakage. A very very nice board! Boot time...

Hi everyone, I have a faulty 2N6394 (Q8) in the Analogue Board of a Mac Plus. Is there an equivalent thyristor I can use? I found 2N6395 sold by Aliexpress, I'm not sure what I will get ... I'm willing to try it, I don't have other options. Is it? thanks

Hi mates, I have an analogue board from a Mac Classic that wasn’t working. There was visible corrosion from a leaking capacitor, but it seemed fairly isolated. I’ve now replaced all the capacitors, and I’m getting a steady 5V and 12V from the Molex connector with the digital board...

Hi mates, I would like to add a retro printer to my collection, possibly an Apple one, laser, without hassle when looking for a new toner and reasonably cheap. Any recommendation?

I am experiencing difficulties with the Carrera040 (Bolle's version) and the ROM-inator II on my SE/30. Observations: Boot Behavior: The system boots in 32-bit mode using the ROM-inator II with a patched System 7.5.5. System 7.5.5 was installed clean and is the Universal version. Extension...

this is the beginning of the repaying of the Mac Plus that went partially on fire https://68kmla.org/bb/index.php?threads/classic-lciii-plus-si-for-for-free.48801/ before how splendid! :D it's better not to be frugal and replace all the darkened resistors, diodes and capacitors. What...

I was handed these Macs for free The Plus went on fire ... what would you do with it??

I’m currently working on a heavily damaged Macintosh SE/30. The original post on the repair process can be found here: Salvaging bombed SE/30. I've restored continuity in the address lines between the RAM multiplexer (MUX), ROM SIMM, VROM, and CPU, and verified the data lines from the ROM SIMM...

I got this very nice Apple IIc, finally! I was looking forward for the whole set!! The pic was taken by the owner, so it's not in my "cave" yet. About the checkboard ... what should I expect? Anything already known? I searched for "checkboard" in this forum but got nothing
