Well, wandering through my handbook collection for something that might be interesting I came across the Microcomputer Products Handbook from 1985. This is a 'Q-bus products overview' book. And lo' and behold we find the tech sheet for the DRV11-WA which is the replacement for the mature DRV11-B. That being said, I'm now on the hunt for DEC document EK-DRVWA-UG the DRV11-WA Users Guide. I'll happily trade a DELQUA users guide or a DHV11 users guide for it. I even found a cab kit for it in my box of misc cab kits. What I haven't yet figured out is how it DMAs into a 22bit address space with a 16 bit Bus Address register. Perhaps there are some bits in the CSR to set bits 18 through 21. In processing a google search I discovered that the DECUS.org archives are now not where they used to be (I couldn't find them easily) Perhaps the coolest thing I've seen so far is that you can almost use this thing to create a front panel for an LSI-11 system. You can certainly deposit and examine memory and start and stop the processor :-) --Chuck
