Need Lisa 2/5 Video Board

[retrotechrestoration]

I'm looking for a replacement Lisa 2/5 video board. Anyone have a known working one they can sell or donate?

I don't, but I'll note that the Lisa video board is the same one you'll find on the Lisa 2/10 and the Lisa 1.

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.

Of course there is a video board, it‘s mounted separately in the chassis.

What a bizarre thing to say.

Of course there is a video board, it‘s mounted separately in the chassis.

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.
