Starting to think the backplane mayyyyy be wonky. Oh. it's just 18-bit. It has a copyright date of March 1977. NETCOM HV-1148. Oh, THAT box! Shit, one doesn't take an 11/03 and shove a MicroVAX in it. Sure, it's Qbus, but there's a decade between them, man! I didn't know it was /that/ old! I thought it was a newer box just with an 11/03 in it! Seriously. Those boxes were sold as 11/03s. To be honest...the linear supply should've given it away. Yes. Now...I DO need a Q22 box. That leaves me a custom-made BA23 enclosure or a BA123. Well, there are also 3U BA11 Qbus chassis with 22-bit backplanes. And 18-bit ones...which you can turn into 22-bit ones. ;) My first MicroVAX-I ran in one of those, back in the 1980s. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
