I looked at the old articles in this group and you are right, it was a VAX, not a PDP11. Do you know anything about a company called Cyon? I have a 68K QBus board that has little text on it but Cyon PN 02-3000-01. It lived in a case that looked like a VT100 with an HDA in the bottom and a small QBus cage to the right of the CRT. The HDA was dead and I was low on space, so the case and HDA went away. I searched some but never found anything on it. BobH |
