    Wifi Extension Development Thread

    This may be not what people are looking for, but my solution for all of my old Macs is simple: AirPort base stations set to extend my home network. Insert ethernet cable: bam. Instant internet access.

    Portable & SCSI2SD Questions

    5.1 is compatible. That is what I have in my Portable. Turns the thing into a System 6 rocket.

    Mac 128k Keyboard Recapping - 1uf 63V

    You are correct. On the machines I have re-capped for other people, I have always left a label that states that I did the job, and what date it was done.

    Mac 128k Keyboard Recapping - 1uf 63V

    Indeed, I have made notes on when either myself or whoever later takes on my Macs (hopefully one of my kids) will need to replace the ones I have replaced.

    You need the adapter as well.
  6. Hi everyone, I have been having an issue with my PT Pro (I guess it was always an issue, I just never used the drives much). I am unable to use the internal CD reader and user-installed CD writer properly. With the Apple CD/DVD driver under OS 8.6, I cannot insert a CD and have it mount. If I start with the CD in the drive, the disc will appear, but then I cannot eject it. Upon attempting to eject, I get an error -50 and the disc will not eject. If I try to use instead FWB Toolkit, I get an error at startup that the FWB Toolkit cannot load because another driver is running the drives...but this is after I have disabled the Apple driver with the Extensions Manager. I am at a loss here as to why this is. I would normally say hardware error, but the same thing happens to both drives.

    Two things: 1. Absolutely would love to see your progress! Please keep us updated. 2. I'd first work on one of the others. Why potentially bungle a prototype while learning?

    Oh I didn't mean yours: your battery was probably a great replacement, I meant the one that he initially had used at the start of the thread.

    Looked at the specs of your battery, it had the same issue the first I used did: fairly low initial max discharge current. The above battery MOS used, and the one that I used down here: https://www.batteriesplus.com/battery/sla-sealed-lead-acid/6/hawk0809=0012 Are better suited for the Portable. As for the capacitors, I made a list I can get to you from home when I get there.

    Paul, i am am not certain what you mean by “it even ran off the replacement battery” - All Portables MUST run off their battery. The power adapter is only used to charge it. Second, are you 100% sure it is a battery that is good for a Portable? The thing shutting down with HD spin up sounds like too much of a current draw on the battery. Certain batteries can only deliver so much current at a time, despite voltage rating (witness an “only” 12 volt car battery turn over that huge motor - much current is supplied instantly). I had a 6V for my Portable that didn’t work, and only once I got a proper replacement was it good. Third, did you re-cap the board? Photos would also be helpful.

    800k Floppy drive question

    Still uncertain as to if that will work on the plus itself though. I’m not sure the IWM is the exact same physical chip a in the II and SE.
  13. Now I think is a good time to refurbish my 14" AudioVision to pair with this. The screen projects on about a 20 degree tilt, so I think the yoke needs to be rotated. The thing was a pain to get open years ago, and I don't think I ever did get it open. I suppose I need the service source document for it.

    As far as I know, IWM and SWIM are not pin compatible.

    To expand on what Brett said, you can also scrape off more coating of the trace nearby, and solder a small piece of wire to the leg of the cap and the other end to the newly exposed trace.
