    Powerbook 100 - factory polymer caps?

    The Console5 cap kit for the PB100 says there are 6 caps that are polymer caps from the factory and do not need to be replaced, so they are not included in the recap kit. Looking at my board those specific 6 caps don't look any different from regular electrolytic caps. My experience with modern...

    M0100 mouse button stopped working

    I just set up my Plus and found that the system no longer recognizes the mouse button. I checked with a meter and confirmed the button is functioning properly. I recently had the machine apart and had the logic board out to install the diode needed to power the external SCSI port and found the...

    SE/30 reloaded - which ICs can be reused?

    I am getting ready to start my 2nd reloaded build, my donor is a working logic board that has developed bubbles under the solder mask on both sides of the board. The solder mask has completely come off of the ground plane on the top of the board at the back by the bracket. For my first build I...

    PB100 was working, then it wasn't

    I recently picked up an in-op PB100. I recapped it today (display, logic board, CPU board) and it started working. This was with no battery installed, I assume the battery I have is completely dead. The HD does not work but the machine comes up to the flashing floppy, so I was happy. I noticed...

    IIsi audio issues with MacSD

    I just installed a MacSD internally in my IIsi and have some strange audio interference. The speaker makes noises corresponding with SCSI/CPU activity. It is hard to describe the noises, but it is like a combination of squeals and clicks. The noises line up with the SCSI activity, and moving the...

    SE/30 external floppy/SCSI port transplant

    I just wrapped up my SE/30 reloaded build. When it came time to transplant the external floppy connector from my donor board to my reloaded board, I was a bit stumped. On some versions of the SE/30 the ground posts of the external connectors solder to the board "normally" - the post comes...

    Re-finish IO shield for SE/30 reloaded?

    I am getting close to wrapping up my SE/30 reloaded build and finally removed the IO shield from the old board. It has a fair amount of surface corrosion. Does anyone have any thoughts on how to refinish it and keep it from further corroding? I thought about cleaning it (wire brush or sand...

    IIsi PDS video card for dual PDS riser?

    Are there obtainable PDS video cards that would work in an IIsi with a dual PDS riser card? I think they existed, but I don't know how common they were, or if they can be found these days.

    IIsi PSU question

    I have a recapped PSU in my IIsi and it has been working fine since the recap - it's been a few months, but probably only 10 hours of run time. The machine has a NuBus adapter and 8*24 video card. Yesterday while I was using it the machine restarted and then went into a restart loop where it...

    Color Classic w/ Sonnet Presto '040 25mhz accelerator

    A couple months ago I was browsing Offer Up and ran across a Color Classic. I had never been a huge fan and did not intend to add one to my collection of compact Macs, but I figured what the hell and went ahead and bought it. The case was in good condition with mild yellowing, no damage. The...

    Color Classic ticking noise - flyback?

    I recently got my Color Classic working thanks to a new logic board from @defor. The machine was working fine, though it was making a whining noise. It was not a mechanical whine, there was no HD in the machine and it was not a bearing whine coming from the fan. I put the machine away for a...

    How to open DC42 files?

    I downloaded some DC42 files from Macintosh Garden and I am having trouble opening them. I am running Mini vMac on a PC. I imported the DC42 files using ImportFl. When I try opening them with Disk Copy 4.2 it just does not see the files. I click "Load Image File..." and navigate to the...

    IIsi different logic board revisions?

    Looking at my IIsi boards, I have one 820-0301-04, and one 820-0301-A. Both boards have the onboard ROMs. The 04 board PCB is noticeably darker than the A board. Does anyone know the difference between IIsi LB revisions? Just out of curiosity.

    Color Classic - no signs of life

    I recently picked up a Color Classic in unknown condition. The first thing I did was recap the logic board. I tried powering up (using a known-good ADB keyboard that works with soft power on my IIsi), and nothing. No beep, no fan, no hard drive spinning up. Just an extremely quiet whine that...

    SCSI emulator for '030 accelerated Plus?

    Moving this post to its own thread, I originally added it to an existing post on a related topic and probably few people will see it there. I have a Performer clone I built that works fine in my SE, and I recently installed it in my Plus. The machine works fine booting from my BlueSCSI v1.1...

    What wire do you use for trace repairs?

    After watching Bruce's videos I bought some coated wire similar to what he was using. Unlike his wire coating that melts very quickly with heat, the coating on my wire seems rather immune to heat. I have had to carefully strip the coating off with a razor before using for repairs. Does anyone...

    What is the gadget on this 512k?

    I ran across an ad for this 512k, it has some sort of a box on the back plugged into the mouse port. It appears to have a slider that goes from tortoise to hare, so I assume it controls pointer speed, but I don't know why it would have both a male and female connector. Has anyone seen one of...

    M0401 AppleColor High-Res RGB monitor capacitor list?

    Does anyone have a capacitor list for the M0401 AppleColor High-Resolution RGB monitor? I found a thread with a list for the later M1297 revision, but I was not able to find anything for the M0401.

    Mac 512k HyperDrive

    I have actually had this machine for a couple years, the conquest is the controller board I just picked up from eBay that brought the machine back to life. When I bought the machine the internal drive did not work. When I first took it apart to inspect it I found that a resistor on the...

    Mac Plus/SE Performer accelerator build

    I just finished my build of a Performer accelerator clone for the Mac Plus/SE. Enormous thanks to @Bolle, he reverse-engineered an original accelerator and posted the board file online, along with the GAL files. Thanks to @DrGonzo, his thread on his Performer build inspired to do my own. Link...
