Does anyone have an idea of the approximate value of this Umax clone? 

Hi Lisa enthusiasts, I have a 2/5 which has I/O problems due to the corrosion and myself and a fellow member are trying to diagnose. I need to find out if the I/O board is the fault or potentially the edge connectors or traces on the motherboard. I don’t have a spare I/O board unfortunately.  ...

Hi all, Sorry to keep bring up my 2/5 saga but I think I may have found out what is wrong. Spoiler alert: I have no idea what I am doing so everything that follows this sentence is said with a deal of uncertainty. Unfortunately my area of speciality isn't electronics (as much as I would like it...

Hello everyone, I hope during this period of global uncertainty and crisis that this message finds you well. I have made some interesting progress with the Lisa that may be of interest to some. I am also posting to request some help in the hope of getting it up and running fully.    So...

So I bought a Lisa and it came with a ProFile and a Widget drive. Both of which seem to not be working anymore. The ProFile didn't spin so I rotated the bearings counterclockwise until the drive started to spin again. However it doesn't seek, I hear the brake release and then nothing. So...

I have a compact Mac with an analog board which I believe is a US model however the rear casing has 240V written on it. When I got the Mac the fuse had blown most likely because the wrong voltage was pushed through it. Replaced the fuse but I was wondering if there are any distinct differences...

Hi Everyone, I bought a 2/5 ages ago and made progress neutralising the battery corrosion on the motherboard and giving it a good clean. I got the system working and verified components were functional however I got stuck at a I/O error 52. Naturally I assumed this error was to do with the I/O...

Does anyone have any idea how to fix this error. Ive isolated the problem to the memory expansion card inside my IIGS. My IIGS is ROM 1 and won't boot with this card present as it gives this error. I had a look on the web but no-one explains how to fix the issue. I feel from what Ive read online...

Hi everyone, I've been working on repairing an Apple Lisa 2/5 with limited success so far. I'm not really sure where to start as the Lisa seems to be acting very strange, for example, if the back cover and front bezel are off, the Lisa will still switch on even though the safety switches are...

Hi all, I recently got hold of an external 400K disk drive that isn't working properly. It had problems accepting and ejecting a disk which are now all sorted, however, it only reads disks it formats?? So if I take a good known working 400K disk it won't read it, but if I format it using the...

Hello everyone, I recently got hold of an Apple ///, however it doesn't want to boot any Apple /// software.  It will however boot nearly all my Apple ][ software using Apple ][ emulation.  Basically it freezes on the Apple /// SOS welcome screen, see image below. The disk drive also stops at...

Hello, I am just wondering if anyone has 400k disk images for MacWorks plus, the original MacWorks, Lisa Guide and Lisa test. I have tried the MacMorhership but I cannot get the images on there to work, unfortunately. (Must be doing something wrong) I have got the Lisa workshop to work so I...

Hello everyone, I have a minor problem with the video from my apple Lisa, it seems to be displaced to the right of the CRT and folds over at end. Is there a way of correcting this? I will add a picture as soon as I can when I figure out how to. Thanks,

Hello all, I have a problem which developed with my Macintosh classic. When I switch it on it will only show a grey screen with the mouse pointer (which you can move around the display)?? I have only managed to get it to boot a floppy with system 6.3.3 so this rules out screen problems and...
