    Performa 640CD DOS Compatible Black Screen in DOS mode

    I recently picked up a Performa 640CD while visiting my sister in Colorado. Pictures showed the Mac side booting fine, and the price was good, and it had the DOS compatible markings on the front! Was looking for a partner to go with my 6115 with a DOS card, so I picked it up, removed some of...

    Case for Androda's Mac Portable VGA Adapter

    Since I didn't learn my lesson about my terrible design skills while trying to build a universal laptop power adapter, I recently ordered one of @Androda's Portable VGA adapters and thought, "I probably should cover this up before I damage it and short out something important". So I build a...

    Best long term solution for powering portables

    I just finished re-celling a few iBook G3 battery packs. While this will allow me to use them without being plugged in, and it certainly maximizes the portable nature of these machines, I had a couple thoughts: 1. I do have concerns about the safety of home built packs. I read up on it, bought...

    Apple II clone - screen full of apples on boot

    I finally got around to trying to figure out this old Apple II clone I picked up some years back (it was one of my first vintage purchases and I had no idea what I was doing). Anyway, it was booting to gibberish on the video out and I read it was likely RAM related. So I removed all the RAM...

    Managing your collections

    Just wondering how others manage your collections. I started with sticky notes on the devices with notes, then moved to a spreadsheet, then I decided I wanted to have a better way to do it, so I went about building myself a system to do it. I am not a web developer, so it's not well written...

    Picked up a PowerMac G4 MDD with the Zip750 drive!

    Someone listed a G4 locally on FB Marketplace and I fortunately caught it quickly, since it had the Zip750 drive with face plate. It allowed me to complete my PowerMac G3/G3 tower collection (not every iteration, but every design) with Zip drives. Unfortunately, I haven't been able to get it...

    The black Mac no one asked for (Powermac G3 All-In-One Molar)

    So, I had picked up a pair of G3 AIO machines recently. Unfortunately on one the right side of the case was badly scratched with terrible black marks. On the other, the left panel had damage. So I took the two good sides, retro-brighted them and took the best internal parts and made a good stock...

    Macintosh II 40mm to 56mm Speaker adapter

    I recently discovered that my lack of boot chime on my Mac II was due to a bad speaker. I looked for some cheap 32 ohm speakers with a 56mm diameter, but the closest I found were these 40mm versions: uxcell 0.5 W 32 Ohm DIY Magnetic Speaker 40mm Round-Shape Replacement Loudspeaker for DVD/EVD...

    Reason Lisa Mouse is So Expensive?

    I have a chance to pick up a Lisa Mouse that was originally with the Lisa 2 I picked up earlier this year. I was looking on eBay and the prices are crazy. I am currently using one of my Mac Plus mice and it works fine, but I really would like to have the original keyboard and mouse. Is the...

I created a blank image in Cameo/Aphid Selector, installed LOS 3 from floppy images on the FloppyEmu. I can boot from it and the image, and load...

    Macintosh Portable horror story

    So I recently picked up a Macintosh Portable from a guy who found it in a home he was flipping. Unfortunately, no power adapter, and the cover over the floppy and hard drive area was missing. It was also a 5120, meaning no back light. When I got it home, I started disassembly with high hopes...

    Help restoring a newly acquired Lisa

    I just got back from my 5 hour trek to pick up one of my bucket list items, a Lisa. It came untested, with a ProFile drive, printer, and keyboard (no mouse). I believe I will be able to use an early Mac mouse, correct? Anyway, I opened it up to remove the battery, only to find it does not...

    SE/30 not detecting BlueSCSI (internal or external)

    I picked up a SE/30 that had some pretty significant capacitor leak damage. I had a transistor at Q3 fall off the board from corrosion. I didn't initially see it, but I had pin rot on UE8 that lead to a jail bar pattern on the screen. I replaced Q3, and installed a brand new UE8, and the...

    SE/30 jail bars

    I picked up a SE/30 off FB MArketplace and in the picture it had the vertical lines and a floppy (interestingly the bars were only on the background - the floppy icon was in tact: But, it's an SE/30, so I figured its is worth trying to fix. I got it home and fortunately, the battery was...

    PRAM battery voltage ranges

    I purchased some 3x AAA battery holders to use as a replacement for the 4.5V. I also bought some Lithium batteries to use because I heard they do not leak corrosive material when at the end of their life. When I threw 3 1.5v AAA batteries in the holder, the voltage is 5.3v. I expected the...

    PG G5 15" DC board issue - L1202 blown

    I picked up a non-working Powerbook G4, 15" recently that was said to have damage to the power port. When I plug it in, I got a light on the power port, so I was hoping it was something easy, like a bad power supply. Unfortunately. it would still not power on, so I took it apart to make sure...

    "coprocessor not installed" error when booting Mac SE with Radius FPD installed with extension

    I picked up this Mac SE a while back because it had a Radius Card installed and I'd really like to add video out to on of my Compact Macs. Unfortunately, I have no portrait CRT to go with it. When I first got it, I tried plugging it into a VGA adapter into a modern display and I got some video...
