Hi Joe; I will be at the workshop next weekend. Is the Vectrex something that can be transported, and can you come to the workshop in order to explore your problem? Being a hardware guy and interfacing a lot of exotic stuff in my main job, I could have a go at your problem. I'll need to know the SCELBI output signal configuration and wether we can generate up a synched time base for the X axis. We can discuss offline if you like.

I'm asking as most scopes have relatively small screens. But the Vectrex game console has a 9" X-Y display. While I know modifications would be needed to accept the input, if it's something you may be interested in trying, I have 2 Vectrex systems, and would be willing to use one for that if you think we could make it work.
