    How-To: Open a Sony MPF52A Floppy Drive

    I have been working on restoring an Apple Power Macintosh 7100/80, first released in 1994. While tearing it down to remove the original PRAM battery from 1994, I decided to also pull out the 3.5-inch floppy drive to service it before attempting to power on the Mac.

    What I discovered was that I couldn’t find any documentation (service manual, blog post, YouTube video) about how to open the drive without breaking the plastic faceplate. So, I made a video of me fumbling around trying to open the drive so you don’t have to wonder how to open it or break any plastic clips.

    Apple Joystick and Retro Gaming

    How about a little retro gaming fun to close out #Appril2? While looking for replacement RAM chips for my Applied Engineering GS-RAM card for my Apple IIgs, I ran across an Apple Joystick IIe and IIc. Not finding one at the VCF East 2023 consignment sale, I snapped up this one on eBay at a reasonable price.

    Now that I have a joystick for my Apple //e, it’s time for a little 8-bit retro gaming nostalgia!

    Appril2 Accidental Apple IIgs Upgrades

    What happens when you tumble down a retro-rabbit hole? You end up making an accidental Apple IIgs upgrade video for the retro computing Appril2 community event!

    What started out as just trying to figure out how to use the Drive/Turbo CF flash card hard disk emulator turned into a chip pulling and drive servicing bonanza that had me going bananas by the end of the day.

    Come watch me try not to use spicy language while I try to get a 3.5″ floppy drive from 1988 put back together again so I can us it with my Apple IIgs.

    VCF East 2023 Recap

    This past weekend was the Vintage Computer Federation‘s annual VCF East show in New Jersey.

    I was a first timer to VCF and I was fairly impressed by the show that was put on. The exhibits were interesting, and the vendors had good products on sale. For me personally, I really enjoyed the speakers, and the hands-on labs – Glitchwrks XT-IDE board build and Commodore 64 BASIC programming.

    VCF East was held on the InfoAge museum campus which featured early UNIVAC computers, several military artifacts, communications, and electronic warefare exhibits.

    I am already thinking about next year’s trip. In the meantime, I put together a “what I saw” recap video. I hope you enjoy it.

    Servicing a Macintosh 12-inch RGB Monitor

    Apple Macintosh RGB Monitor, via RecycledGoods.com

    Apple’s Macintosh RGB monitor was intended to be the companion monitor for the company’s Macintosh LC-series of computers.

    Before I could set about working on my Macintosh LC III #MARCHintosh2023 project, I needed to service the monitor that my LC (Low Cost Color Computer – I know, the acronym seems to be missing a few letters) was going to need.

    Come watch the roller coaster ride of will he or won’t he repair this monitor but stay to see if I electrocute myself!

    Apple Macintosh 12-Inch RGB Display

    Better get a Band-Aid because I don’t think a Magic Eraser can buff that out!

    I purchased a Macintosh LC III (1993), the companion Macintosh 12-inch RGB Display (1990), and an ImageWriter II printer (1985). What can I say? The Mac had an Apple IIe Card (1992) installed.

    One of the things that you will inevitably have to deal with when you get into retro computing is tracking down technical information about the equipment to repair and service it.

    As for my monitor, well, as you can see from the picture above, old brittle plastics don’t always hold up to the stress of being shipped around the country. I’m using PAPPP’s blog post to help me take apart and get inside my monitor so I can replace the CRT housing.

    I wanted to share the information that I collected and downloaded. Hopefully, if you are looking for more information about the 12-inch RGB Display that has found its way to you, this will help.

    PAPPP’s Rambling – Apple 12″ Macintosh RGB Monitor Recap discusses how to open and replace leaking electrolytic capacitors.

    Good luck with your repair! A serviced CRT display is one less CRT display headed for a landfill!
