    PowerBook 500 Series Battery Rebuild Failure (Oops, all dead EMMs!)

    Yeah, they are a hassle .. but I can’t let go of the portability :) I also leave them in but check them every few weeks. I probably should leave them out but even then, I think the EMM still consumes energy so it’s still an issue. I took apart my battery. Everything looks fine inside but the...

    PowerBook 500 Series Battery Rebuild Failure (Oops, all dead EMMs!)

    I check my laptops every few weeks to ensure the batteries haven't gone down to 0V. Found my 540c wouldn't boot last night. My Sanyo "A" pack was down to 0. But the pack was fine and it recharged and it's holding charge. My "AA" pack however is not responding. It's not detected in either...

    Powerbook Duo 280c + Accessories Maintenance

    I had been under the impression that all the Duos share the same keyboard but given I have only played with a 280c, I cannot be sure of that. Maybe @3lectr1cPPC knows?

    Powerbook Duo 280c + Accessories Maintenance

    I didn’t like how if I caught the key at the wrong angle, it wouldn’t register a press which massively increased the amount of typos. And one of the keys just stopped working again even after using a conductivity pen on the trace.

    Really? They don't even sell it? The recyclers here seem to resell the stuff for cheap.

    Powerbook Duo 280c + Accessories Maintenance

    Latest update for my PowerBook Duo 280c. I'm not the first. @techknight demonstrated his earlier this year. I stumbled upon his video while working on mine. Took a bit to get this to work, primarily because I made a small mistake on the first PCB and had to wait for the tariff situation to...

    There's not much room... between a backing plate, the PCB, the lowest profile (and reasonably priced) switches, I'm already over by 5mm above the stock height. Lid still does close (it pushes the keys down a bit). I was going to shave off the stems from the stock caps and glue in 3d printed...

    Warning - floppy drive head mechanism glue is deteriorating

    Watch from 39:11 (39 minutes and 11 seconds into the video). He specifically mentions what you can do if you have stretched out the heads so that they are no longer against the media. Fairly common mistake that's made while attempting to clean the heads.

    Identify SE/30 video card

    I just got the same card (as @unity) from @techstep yesterday. Unfortunately I currently don't have a means to test it since my only SE/30 has @zigzagjoe 's LCD kit in (ie. the CRT tube and everything, analog board, etc are all removed and packed away somewhere) and the video card for the LCD...

    I still don‘t get it. Why not just upload your findings to Macintosh Garden, like everyone else?

    Portrait Display, fully recapped and working great. The lower left corner geometry needs a little work but I'm going to leave it for now as it's not that bad and it's really difficult to reach the magnet for the lower corner while the display is operational. Dark spot is just the refresh.
