    Very sick Classic --- could it be a bad VIA chip?

    I've had a Mac Classic (actually my first-ever computer) that's been ill for a while. Here's a report from a long time ago --- although it's a lot sicker now. I'd love to get it working again (since it was my first-ever computer :) ). The symptoms today are these: Switch it on after a long...

    Minor, useful update to NeoWidEx

    Hi Lisa fans! A lot of people seem to be working on their Widget hard drives lately, so I've made a small change to NeoWidEx that may be useful for troubleshooting broken drives. For more detail, I've made a longer post on LisaList2. I thought I'd mention it here for non-subscribers to that list.

    VideoMacPacHack: PDS video card for the Mac Portable

    Hi folks, check this out: That's a Mac Portable driving an external 800x600 SuperVGA display in addition to its 640x400 LCD. It's no trick---Flight Simulator 4 is putting windows on both displays. (Yes, it's Woz's autograph too but that's not important right now.) The secret is this board...

I put all of the plans and software online and...

    Maaaaaaaaaaac Claaaaaaaaaaaaaaaaaaassic

    My old recapped classic has some ADB gremlins I'm trying to debug. More specifically, the symptoms are that the system starts to behave as if the "a" key were being held down. Sometimes this can be interrupted, but usually not. This can occur even if the keyboard is not plugged in (and just in...

    Announcing NeoWidEx

    (Crossposting from LisaList; hope this is OK. I know not everyone reads both forums---I didn't join 68kmla until very recently!) Hi everyone, I've made something that might be a useful addition to the Lisa fan's toolbox: a formatting and diagnostic utility for Widget hard drives. In the...

    Yet another backlit Portable power problem---where to probe?

    Hi all, excited to be a new member. My friend and I have been debugging a recapped 5126 lately and are looking for some advice. Once again this machine was recapped some time ago  :) The machine is in OK shape overall with a well-behaved 40MB hard drive. Unfortunately, leakage from the three...
