Hello, given recent posts about Unibus graphic systems, I'm coming back with a request: was anyone some documentation about board sets VT30-H and VTV30-J? They should be graphic systems as well, the former Unibus, the latter Qbus. Definitely I think they aren't "regular" DEC products, maybe they were developed by third parties, as the PCB realization and style is far from DEC boards. I think they are really hard to find parts, would like to try to do something with it. Thanks Andrea
