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

I want to build the Performer-SE-PL-CL accelerator. Since some of the members here already built it, I am wondering if there is a list of components shared in Digikey or Mouser. A compatible Excel file to readily also'd works thanks

My conquest here https://68kmla.org/bb/index.php?threads/salvaging-a-bombed-se-30.48542/ is being salvaged.. at least I'm trying to. I removed the obvious destroyed chips: RTC, D1, D2 (caps are the easy thing) and the RAM muxes UJ1, UJ2, UJ3. I'm now looking for continuity, the traces from the...

Hi guys, For a decent price I found a bombed SE/30 that can hopefully be salvaged. A reloaded board is the B plan. As I got it: after a round in the dishwasher and some scrubbing with vinegar: I need to keep scrubbing and rubbing, more washing and rinsing ... At this moment it does...

There are a couple of threads about this topic. https://68kmla.org/bb/index.php?threads/adapting-the-late-mac-classic-crt-yoke.46777/ https://68kmla.org/bb/index.php?threads/are-the-early-and-late-macintosh-classic-analog-boards-different.46814/ There is a common understanding that they are...

This is a very sad post that will show my dumbness, I really would like to be anonymous now. I was assembling my lovely SE/30 adding the Bolle's GreyCake card on top of the Carrera040 and the Ethernet card. It was all fine, until the last reboot before closing the case, when I did the dumbest...

Hi everyone, this post will be very likely nonsense. In the early 90s I was using partition magic daily: boot, hotkey, select OS, return, restart. It could have been DOS (3,4,5), NT, OS/2 or Linux. Would it be possible to do the same for SCSI-emulated-based Macs? Yes, the technology would be...

Hi everyone, say hallo to the new babies, welcome! The PowerMac is working but it was not provided with the video connector :( The Performa 450 is silent even if the fan spins, PSU to test + MB to be recapped The Mac IIsi cold & dark ;), PSU to be tested and a recapped. NuBus adapter present...

Hi mates, this is a good period ... I got a Mac IIfx, not bombed with no caps leakages. It's in its way, so I have only pictures at the moment. I see there is a: - Apple 820-0400-06 630-0400 Macintosh Display Card with expansion SIMMs - Nubus rev 3 Network card with RJ45, no precise...

I found a Mac IIci, no HD, with a floppy drive, video card, 8MB and PSU for a nice price. I need to recap it, the electrolytic caps have leaked but apparently it's not that bad. I'll leave the axial ones. I did not open the PSU yet, it will need a recap as well I did not have yet a IIci in my...

Hi pals, I have something that can be useful to other and some questions at the end. I was struggling installing Netatalk as a docker container in my NAS 218+ when I noticed the error "port 548 already in use" .."WHAT???". I then recall an AFP flag in the "File Services". When I installed it a...

Hi mates, which cases are compatible with the centris 660 mother board? IIsi, IIci maybe? Thanks
