Again, let me apologize saying there was no video board on the Lisa. While I’ve built dozens of computers over the years - most were PC’s and in a PC, a video card typically plugged into a bus slot, had a GPU and lots of memory. The video board on a Lisa and compact Mac’s is very different. I’ve...

Sorry, my mistake. During most of Adrian’s series, the board that drove the CRT was disabled so it would not drive a CRT, and was kept connected to put a load on the computer’s power supply. Nearly all troubleshooting was done with a video converter that connected to the video connector driving...

I watched Adrian’s Digital Basement series - 9 episodes on YouTube. There is no video board in the Lisa 2/5 If you are referring to to the board with the video connector, Apple call this a motherboard - it’s a backplane. The motherboard was heavily damaged on Adrian’s machine, and he assembled...

I would look for a used HP LaserWriter somewhat newer than the one you were using, that features an Ethernet port.

FYI, in February, 2026 Apple unexpectedly released a security update for OSX Catalina to address expired security certificates. This means most Macs that were released in 2012 can still be used in 2026. Here’s a link to the article from MacUser...

Try holding the Option key down when you select the Monitors control panel, to see additional video resolutions. If that doesn’t work, I wonder if you have the correct Monitors control panel that matches your operating system version.

Ok, didn’t know how many computers had an AUI port. These must be some unique computers, as Macs typically had an AAUI port and 10baseT cards that work in PC’s are inexpensive ($10-$15) on eBay.

Here’s a link to a 10baseT hub with an AUI connector for $19.99 on eBay...

I think your idea for an AUI to AAUI adapter is a good one. I had another idea. I remember in the 90’s you could find inexpensive 10baseT hub with a single 10base2 connector. I used one in my office to bridge a 10base2 network to a 10baseT network - plug and play. I just searched eBay and found...

Remove the red battery before it explodes. I’m fairly sure the computer will work fine without a battery.

Very nice computer

Why is there a dark spot about 3 inches big near the fan, inside the case? Or is that a shadow? I would clean out the inside with a can of air and confirm the fans are working. The loose RAM stick will definitely cause the computer to freeze.

Nice job. FYI Joe's Computer Museum sells the Pico Micro Mac with MicroSD card reader https://jcm-1.com/product/picomicromac/

I had a 3Dfx Voodoo 2 card and an 10 MB ethernet card installed in my C500. I was amazed the first time I saw Unreal running on that machine - a Mac gaming computer!

I owned a C500 for a few years. It was an improvement over the Performa 6360 it was based on, because it had more PCI slots and a faster CPU.

Sounds like replacing the capacitors is working. Great job.

I'm very surprised the Sonnet card didn't work. Are there any signs of capacitor leakage on the 6500 logic board?

In my experience, USB1 cards made by NEC work well on PCI Macs based on the 6400/6500. The source of this info was on www.xlr8yourmac.com I just learned this site closed down November, 2025 https://appleinsider.com/articles/25/11/05/xlr8yourmac-goes-offline-ending-an-era-of-diy-tinkering

Interesting program. FYI the latest Macfilm v2.0.11 was just released 2 weeks ago. All previous releases were from 2022 and 2023.
