When first powered on, the geometry of the picture is fine. Over time, it moves to the left. The analog board still works but hasn't been recapped

I thought I'd get myself to learn PCB design by modifying Bolle's MicroMac Performer clone to remove the PDS slot and Classic CPU socket, thereby specializing the upgrade for a Macintosh Plus only. I started from this repository which has several KiCad projects you can just open right up...

I just recapped a Sharp passive matrix display from a PowerBook 160, it worked fine for the first hour but then the top half of the screen started flickering and went dark. If I crank the contrast I can see the top half flickering in darkness. I think it could be a bad connection with one of the...

Thought I'd post this in case some here would be interested https://www.vogons.org/viewtopic.php?p=1362715

Well, I made the Bad Mistake of leaving my PowerBook outside and it'd got rained on a bit with the cover closed. I disassembled it and dried the motherboard, daughterboard, and RAM expansion card. Luckily there was no water on the right side where the floppy and hard drive lives. When taking...

Has anyone here bought this adapter? Does it have a switch for SCSI Disk Mode? https://www.ebay.com/itm/324041684642 I want to connect my PowerBook 180 to a SCSI PC and transfer files. I still have the original IBM hard drive installed

I've had this NuBus card in my Macintosh IIcx for a while now. After installing the RadiusWare utilities set, all video modes are accessible and switchable on-the-fly. But when opening the QuickColor control panel it lists no Radius accelerators present and there's just two radio buttons to...

I have come into possession of twenty 800k floppy disks from EDUCOMP which appear to contain various HyperCard stacks. I'd won them at auction on eBay originally as a source for cheap 800k diskettes to use with a Mac Plus, but now I see these may contain software that hasn't been archived yet...

I noticed the Macintosh seems to have provisions for NTSC/PAL composite output, according to the monitor sense codes documentation. Has anyone successfully coaxed a composite signal out of the Mac video port?

Today I tried to setup RAM Doubler on my PowerBook 180 only to discover I couldn't type my name on the keyboard. When opening Key Caps it says there's "no description for this keyboard" (the built-in one). external ADB keyboards work fine. I tried reseating the interconnect cable and the...

I got my PowerBook 180 in the mail yesterday and opened it up as I noticed the trackball needed cleaning. Inside I found two stickers from previous repairs in '93 and a bunch of ancient battery acid stuck to the case, which I scraped away using an X-Acto knife. There's at least one bodge here-...

Hi all, I've been wanting to buy a PowerBook 1x0 for quite some time now. As of recently, I'm trying to figure out the best way for me to rebuild a battery for it. I've decided to go the route of utilising as many off-the-shelf parts as humanly possible, which means I'm going to use simple...

After getting my LC on Wi-Fi using the new DaynaPORT SCSI/Link emulation for BlueSCSIs, I wanted to try using a proxy to visit SSL-enabled (HTTPS) websites from a vintage Mac. As you may know, 68k based Macs don't have enough computing muscle to handle the encryption employed by modern SSL...

I thought it would be a good idea to start a thread for my own vintage Mac adventures, which I hope will include a PB 180 in the future (although that seems slim now). I’m currently still working on my trash-to-treasure LC, trying to revive the internal SCSI hard drive. It doesn’t mount, (it’s...

Yesterday my Wireless BlueSCSI v2 kit arrived, so I soldered it together and used it to boot up my Mac LC. I started out using System 7.5.3 but I quickly upgraded to 7.5.5, the newest system software the LC will run. Then I began my attempt at a wireless LC. I installed the DaynaPORT drivers...

So, back in the day there was an internal mod for PowerBooks (ones that didn’t have video out) that allowed output to an external monitor. It was made by Mirror. https://68kmla.org/bb/index.php?threads/some-mod-for-powerbook-170-display-out.32379/ While searching for PBs, I saw a fully...

I recently picked up a trashbin Macintosh LC and Apple Keyboard II all for $20. The LC was caked with dust, the keyboard was caked with white fur. Cleaned both up and they’re almost good as new. Then I plugged in the power supply. 12v was basically nonexistent. Opened up the power supply, (TDK...
