It was with interest that I saw a posting that said no 6 wide Qbus cards existed. I have a couple I think. I have two of PCB 136 Qbus sys boards. http://members.aol.com/innfosale/ebay/136qbus1.jpg I think they are like a console card as they have eproms, LEDs, switches to set, Tst/Nor, Hit/Run and restart switches. Maybe came out of a qbus card tester? I have a SDLC card, PCB127 that I will get pics up shortly that is 6 wide but not marked qbus but is a similar board number sequence. This board has a 2652 CPU. http://members.aol.com/innfosale/ebay/127qbus1.jpg So are they qbus cards? -- Paxton Hoag Astoria, OR USA
