If the traces can be followed from the top of the PBC I can help out at any time! If I need to disassemble the card cage to get to the underside of the PCB, I might ask you to batch your requests since it's fairly cumbersome to pull apart. Full disclosure: After using this Lisa actively for a...

I tried running my Lisa without the I/O board. It started up (automatically, as you guessed) and soon hits error 41. But there is code executed at least, and an error displayed on screen. As for Motherboard schematics, I've also not found easy to read reference material. I think parts of the...

I didn't replace too many parts to be honest. Looking at my Mouser order history, here are the relevant components that I can note: 1x Film Capacitors 0.1uF 250volts 10% (PSU) 2x Film Capacitors 0.0022uF 250volts 5% (PSU) 2x Aluminum Electrolytic Capacitors - Radial Leaded 25VDC 2200uF 16x20mm...

Yes, if you look closely at my previous comment, I linked to the specific disk image that I used, hosted over at the Mac Repository. I simply loaded this onto my FloppyEmu running in Lisa mode, and it worked without issue on my Lisa.

As an addendum, the computer passed all core LisaTest 3.0 diagnostics with flying colors! I don't have loopback cables to test the serial and parallel interfaces, however.

Despite Steve Job's best efforts in revolutionizing the UI of Apple computers, there are still occasions when you need a keyboard handy while using a Lisa. For instance, when pressing 'Y' to accept the terms and enter the Basic Lisa Utility. :) As such high up on the priority list at this point...

With the computer now powered and executing ROM code, we were no longer fumbling around in the dark messing with the arcane mysteries of mains voltage! A quick voltage check on one of the ROM chips on the I/O board while the computer was running confirmed a nice and clean 5V. Luckily, Lisa...

In part three, we will bust open that PSU to see what's going on inside. We also take a moment to look at the Video Board. Here it is worth remembering that my friend, the owner of this Lisa, said that he recalled the computer not being quite functional circa 1994: only running for a few...

Time to deal with that battery damage! Special thanks to @Elemenoh in this episode for helping me identify several replacement parts. Step one is always to neutralize the alkaline rot. Household white vinegar to the rescue. I use distilled vinegar diluted to 5% acidity. Here demonstrating my...

Earlier this year, a friend mentioned to me that he has had an Apple Lisa 2 in storage for many years, a machine that he acquired in the early 90s that had never worked properly for him. The symptoms, as he remembered them, was that the computer would turn on and run for a few minutes, and then...

You are welcome! Yes, this commit fixed the bug (which is what I referred to above as the Error -50 issue). BTW, one changed behavior that I've noticed after using this release for a while, is that copying certain files over DSI leads to afpd erroring out with dsi_stream_read: len:-1, No such...

I'm proud to present a new release from the Netatalk 2.x fork: https://github.com/rdmark/Netatalk-2.x/releases/tag/netatalk-2-220401b This version constitutes a massive refactoring, code cleanup, plus security and stability improvements. The primary functional change is that the configure...

An update on this: I found some technical documentation for my 386 motherboard in question and realized that there's an external battery header, J1, sitting just below the internal battery compartment. I could not detect any charging currency going into this header either, and some discussion...

Good question! The battery is KTS brand and looks like this. There is scant information online.

Actually, I may have been incorrect in my assumption. When I tested both the internal and external battery headers with my multimeter, neither had any noticeable voltage supplied to them when the computer was in operation. Would you say it's safe to assume no voltage means that the motherboard...

I suppose this would work, although I believe a diode needs to be connected in serial to stop the motherboard from feeding 5V into it. Personally, I'd prefer a solution that doesn't involve soldering a battery directly onto the board, however.

I was recently given a 386 for free that had been used as a phone and fax switch at a local theater for decades, but had been decommissioned at some point and was gathering dust in a corner. It's a late-era 'industrial' 386 with IC date codes from 1995, and I was able to extract the PMOS...

Bug Alert: Netatalk 2 will fail to create icon resources for classic Mac OS files copied onto the AFPShare when running on 64-bit Linux. On Mac OS 7.5 and earlier, files will still be copied but when you access them from another Mac, you will notice that they have lost their icons, reverting to...

While working on refurbishing a Macintosh Color Display M1212, I took the opportunity to record the electrolytic capacitors on the "analog board". There didn't seem to be any electrolytics on the neckboard. Location Capacitance (μF) Voltage (V) Diameter (mm) CF10 220 35 10 CF11 470 25 10...

I'm glad to announce the first tagged release of this Netatalk fork! A broader group of people have tested it for a good few weeks now, and code changes have been minor recently, so I think this is as good a time as any to cut a "stable" release as a baseline for further development. Find the...
