I'm looking for a replacement Lisa 2/5 video board. Anyone have a known working one they can sell or donate?
Need Lisa 2/5 Video Board
- Thread starter retrotechrestoration
- Start date
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 a new board, which was recreated and the link to the gerbers is on GitHub. Check the playlist for the relevant episode in the series.

What a bizarre thing to say.
And a substantial part of Adrian's episode 8 (or so) is all about fixing it!
This isn't a mixup of nomenclature either. It's literally called the Video Board. It has "VIDEO BOARD" written on it.

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 a LCD monitor.
OK, yes, on the Lisa this board is called the Video Board...
That's a slightly snarky thing for me to say, but it got me wondering, so I went back to Adrian's video series (I've already seen all of it too) and searched through the transcripts. Adrian appears not to call it the Video Board; he uses terms like "CRT driver board" instead. So fair enough not to be familiar with nomenclature he never uses.
BUT... it kinda goes to show that even ten hours of YouTube can't really make you an expert. Adrian's videos are great and I've already recommended that people getting to know Lisas take a look at them. Here I am doing it just two weeks ago, right here on 68kmla. We've been following his videos with enthusiasm over on LisaList2. But it's pretty clear that he's new to the Lisa, and there's lots of stuff he still has yet to discover. For example, on the last episode, he says there's no way to reboot the Lisa from the Office System short of turning the computer off. He is wrong: you hold down the Apple key and press the power button to get to the Environments Window, where you find a Restart button (image). There are lots of other things that I've learned over decades that he just hasn't discovered yet, and that's fair enough. I don't say this to say that Adrian doesn't know what he's doing or to proclaim myself an expert --- he's learned a ton and I've learned a few things I didn't know myself from his work --- but instead I say this just to reinforce what I typed in bold just above.
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 been a Mac user since 1994 as a user and collector, not a repair guy.
