OK. I did some digging around for 3 year old conversations and links. The Grant Technology 306A is the fully-stuffed KWV11 + RTC board. If it's 1/4 stuffed with just the RTC portion, it's a 307. Manual at: http://bitsavers.informatik.uni-stuttgart.de/pdf/gtsc/979-0021-306_GTSC306_Sep88.pdf RT-11 routines at: https://archive.decromancer.ca/pdp-11.classiccmp.org/RT-11/freeware/decus11/110645 One 306A sold last year on fleabay for $27 plus shipping. If I had seen it, I probably would have bought it. I don't think there are any photos easily findable online. The manual on bitsavers has some great technical details but sadly no schematic.
