Neat! Is the rsx code or source code for the rtc anywhere? It's less necessary now
that we have ntp from the tcp stack (thank you bqt) but it would still be cool

The DEC KWV-11 is designed to support analog and digital acquisition
boards. See EK-ADV11-OP-002 ADV11-A, KWV11-A, AAV11-A, DRV11 User's

Interesting. I have one does it emulate a kw11?
Can it keep the date and
time between reboots?
I think it's a KWV11 plus an RTC. That MicroPDP-11/53 came with
MicroRSX-11 and there was a program for reading the RTC. It complains
when I boot it up and the board is missing.
It shouldn't be impossible to figure out how it all works and write a
program for RT-11 or possibly 2BSD to read the time.
Oh... there are product variants for how much of the board is
populated. I think mine is "RTC only".
