【Buyer Beware】The Blind Trap of the MacBong! Mini Keypad: Identifying the Compatible Chipset (Teardown Review)
Hello fellow vintage Mac enthusiasts, Kay Koba here... One of the best quality-of-life features of MacBong! is its support for a mini wireless keypad. When your test bench is cluttered with logic boards, multi-meters, and soldering irons, you don't want a massive keyboard taking up space. Having a tiny keypad right next to your project to test and boot systems is an absolute game-changer. However, there is a massive catch if you are looking to source one of these keypads your

Technical Note: Diagnosing ROM Socket Contact Failures on the ROM-inator Resurrections.
We have received several inquiries from builders stating that their newly assembled ROM-inator Resurrections fails to boot, even though the assembly appears structurally sound. In approximately 90% or more of these cases, the root cause is not a defective ROM-inator PCB or a soldering error, but rather a mechanical contact failure inside the vintage ROM socket on the host logic board. It is always disheartening to see posts from builders who feel discouraged when their kits d

But lose the manual, and it quickly becomes impossible to tell which switch does what. Today, almost everyone uses LCD displays. That made me wonder why not simplify this overly complicated, now somewhat nonsens

Super Wh-IWM Swapper with PowerBook’s SWIM Chip 343S1029-A
Some time ago, I was working on the Super Wh-IWM Swapper (PLCC44 to DIP28 SWIM adapter) . However, due to the shortage of SWIM chips (343S-0061-A, 344S-0061-A), and the fact that even when available they were extremely expensive, the project stalled. In reality, the only practical option was to salvage SWIM chips from logic boards damaged by battery bombed and corrosion. In a way, this makes sense. The SWIM chips used from the Macintosh SE/30 through the Macintosh IIsi gener
