    How dangerous are RIFAs?

    I've got a Mac Plus that appears to be stock (aside from 4MB of RAM) and I'm wondering about the RIFA caps. First of all, do I really need to replace them? I'm not adverse to soldering---the analog board probably has cracked joints anyway---but I don't like waiting for parts (and paying $10...

    Interested but confused about 68k PowerBooks

    Hi all, This isn't a buy-sell post, it's more like a question post. I'm interested in getting a 68k PowerBook, because I want a Classic 68K Mac without having to store a Compact Mac or a pizza box+monitor. Also, the performance in the 68k PBs seems pretty good (better than a Mac Plus at least!)...

    When I got my Mac Plus, it came with an ADB mouse and keyboard. Obviously those are useless with the computer, so I gave them back and pursued other options in the interest of cost (it's about $150 for a used and compatible keyboard and mouse). I found a cheap PS/2 mouse to Atari ST converter on...

    128K ROM Changes

    This is a thread purely of questions. If these are actually super obvious and I'm just missing something, feel free to disregard my post. What changed between the 64K ROM and the 128K (Plus/512Ke) ROM? The things I know of, beyond bug fixes, are HFS, the SCSI Manager, the 800K disk driver, and...

    Mac Plus and HD20

    Hi everyone. First post here. This seems like the most active vintage Apple forum, aside from perhaps r/VintageApple. I have recently gotten my hands on a Macintosh Plus and an HD20 (not the HD20SC, though). It's my first foray into vintage Apple stuff. The Plus was upgraded to 4 MB of RAM...
