    Lisa Video Board

    Hello my fellow Lisa geeks ! Can someone help me diagnose this video problem ? The video board was originally OK-ish, but with some jumpy behavior. So I went on to change all 10uF e-caps (2x100V and 3x16V) which has always worked for me. But then I got this screen below. Tweaking all pots does...

    Mac SE30 not seing the FDD

    After so many years, I decided to go through a pile (dozen) of SE-30 logic boards that I had bought on CL. I meticulously recap them one by one, and some of them work, but others don't. This particular one gives me the following symptoms: 1) Booth chime is OK. Video is good 2) When no FDD or...

    Profile 5MB and 10MB HDD Models: Serial Numbers

    I recently realized that among my four Profile HDDs, one of them is actually the 10MB model (from looking at the controller and the HDD), even though the model number was A9M0005. See pic below This spurred me to look into model and serial numbers. First of, my other three "true" 5MB show...

    Sad/Death Chime on IIci

    I have a Mac IIci which I recently bought off CL in San Jose. At first, it only powered up if I kept on pushing the power button, and even with that it only showed the power on green light, with no other sign of life. I recapped all electrolytic SMD capacitors on the LB, and I now have good...

    De-serialize Lisa System and Lisa Office Diskettes

    Since I spent so much time figuring out how to de-serialize Lisa diskettes, I figured I'd post the "how to" in order to perhaps help the community. There are a lot of bits and pieces on-line, but nothing really comprehensive. So here we go Of course, an easy way to go is to download the...

    Mac XL downgrade back to 2/10

    I'm not having too much luck posting my issue on an old thread in this forum, so I'll start a new one. I'm trying to convert my Mac XL back to a 2/10 model. To start with, I took the CPU board from the XL, swapped the two ROMs and the VSROM chip from my good 2/10, inserted this converted XL CPU...

    Post repair summary

    I recently acquired a Lisa 2/10 from its original owner, on Craigslist (SF Bay Area). It came with an original Lisa 1 mouse (:p), and lots of software with manuals in mint condition. The cosmetic condition of the Lisa was impeccable, but it did not quite work. The screen was shaky, and you could...

    MacColby/128k Screen Issue

    My current project from the Colby estate is to revive a MacColby (1st pic). When I first turned it on, I actually got a loud bong, and the usual floppy question mark, so I was elated (2nd pic). It took me a while to de-stuck the two floppy drives, and I could get everything going in record time...

    Disks Corrupted after SCSI Conflict

    So I had two perfectly good HDD's in two different external enclosures. One was big (1.7 GB), and the other one that I just revived from the "Sticky Actuator" syndrome, a 40MB Quantum Prodrive. I wanted to copy the content from the 40MB into the 1.7GB. So I daisy chained both of them to my SE...

    Walkmac

    I recently acquired an original Walkmac (photo below) from the estate of the late Chuck Colby, founder of Colby Computers. The Walkmac used a Mac Plus logic board, and attached an LCD and a battery to package an arguably fully portable computer (it still missed a keyboard and a mouse), a full...

    Walkmac: Can you boot a Mac Plus without the +12V line ?

    So I recently acquired an original Walkmac (photo below) from the estate of the late Chuck Colby, founder of Colby Computers.

    New Internal HDD in Color Classic

    I have a Color Classic that had a dead Conner 80MD hard drive. I was trying to replace with an IBM WDS-L160. Everything works OK when an external drive is also connected, and the system boots flawlessly from the new IBM drive. But when I disconnect the external drive, the system does not...

    Solved Classic II no sound cap issue

    I thought I'd post this here to perhaps help some. I have a Classic II which worked OK, but with only a faint sound. So I thought I'd recap, but only those caps I guessed were involved in sound. Started with C11, C12, C14 and C15: no help Then C9: no help After I changed C4 (47uF), I finally...

    Horizontal line on Mac Classic

    I'm hitting my head against the wall on this one. The system boots (firm bong), but the screen only displays a half horizontal line (photo below). I have replaced all the usual suspects on the AB (brown caps) and voltages are OK (5 and 12V right on the money). I checked the H and V sweep...

    The most interesting Mac Classic graffiti

    As I was pulling another Mac Classic from my collection to repair, I noticed a faint writing on it. Upon further inspection, here is what I found (photo attached). I usually start my repairs with a thorough clean of the case, but I think I'll leave this charming graffiti. I might even retr0brite...

    The cast of characters in the Mac SE Easter Egg

    I was recently in contact with one of the early engineers on the Mac team and we discussed the Easter Egg on the Mac SE (set of 4 images that flash on the screen after typing "G 41D89A" in debugger mode). I asked him if he could identify some of the people on them, and he knew two of them. In...

    Zip Drive

    In my eternal quest to find the easiest way to transfer files between the cloud and my vintage macs, I recently purchased two Zip100 Iomega drives. One has the SCSI interface and connects to the Classics, and one that has a USB interface that I connect to my Macbook. So I can copy files from the...

    I think I have graduated !

    This was long in the making ! Almost 5 years ago, I purchased a Lisa 2/10, well technically a Mac XL, from someone on Craigslist. The story was actually very cool. The seller said that he was working as a cameraman for NBC News, and he was the one filming the 1984 Mac launch at the Flint Center...

    G3 to SE/30

    Hi: I'm looking at the best way to download legacy Mac software from the Internet to use on my Compact Mac (eg SE/30, CC etc..). In the past, I used my old WinXP computer and it was tedious, but it worked. Now that I have Win10, it does not work any longer.  So, what is best way to do this ...

    HDD Bad Blocks

    I have revived yet another SE30. The HDD, however (Quantum Prodrive 80S) is throwing errors. I thought that a Lido format would find and reallocate bad blocks, but it does not seem to be doing that. So I tried the "Overnight Test" in the Lido software, hoping to do just that. However, it seems...
