I'll have to get round the back of it and see what's on the nameplate. I can take some pictures but won't be able to upload them while the current lockdown carries on. It's currently not linked to anything.

I also have a PPL frame buffer which uses a hard disk as the video memory (rotates once every frame time, the video signal is recorded as analogue FM) with a Unibus interface. And 3 I2S (International Imaging Systems) video display/processor systems -- a Model 70/E with 6 planes, a Model 70/F4 and a Model 75. I do have a lot of documentation, including schematics, for those. -tony
