I've just been made aware of a very interesting web page: https://www.retrotechnology.com/herbs_stuff/m_parts.html#800K that details some of the differences that I've been noticing. Apparently some of my drives have black text on their labels while others have red text on their labels, and this...

Anyone know about Sony 800k floppy drives? I've been learning a lot about them lately as I attempt to get a couple of MacPlus computers ready to sell. I watched a few YouTube videos (especially those from @JDW, which are pretty amazing!), and learned a LOT about what I need to do with these...

I'm sorry but I do not think I will be selling the analog board on which the sound doesn't work, because believe it or not, once I moved the speaker to the other analog board, it now appears to work just fine. Also, I'm thinking about re-capping the analog board so that when I sell it...

Hello I have a bunch of Sony MFD-51W 800k floppy drives that I'd like to put back into my Mac Plus computers so that I can sell them. Fortunately, I was able to get all their eject mechanisms working properly, thanks to James Wages' terrific instructions! But many of the drives have the same...

Well despite the fact that I tested the speaker using an ohmmeter (tapping the test leads on the speaker terminals produced crackling from the speaker and by that method it tested "good"), the culprit turned out to be the speaker itself. Swapped it out with one from another analog board, and now...

Ahhhhhh! Thanks ever so much for taking the time and thinking about it more! I'm sorry, I should’ve mentioned that the issue exists no matter which logic board I put in the computer...so I think it’s safe to say that it’s not related to the logic board. Also, fwiw, I traded out the analog to...

Thanks! I’ll definitely check that out! I think I already re-flowed all the joints of that connector, but I’ll double-check!

I have a few Mac Plus computers that I'm getting ready to sell. One of them doesn't make any sounds out of the speaker, but sound does come out of the headphone/external speaker connector. Just wondering if anyone knows the usual reason for this failure?  I've tested the speaker with an...

Someone asked why MacColby would make such a computer?  Well, having traded in my Mac512 for a MacColby in 1985 or so, I can tell you that the MacColby was a HUGE improvement over the original Mac in terms of portability! Not only was pretty much everything inside the case, but the keyboard...
