My 3100/10 has a KA410 board. Perhaps I should try it and see what
happens. What's the status of the KA410 mainboard? It seems that I
should download -current and give it a try.

I wonder if the machine will boot from an external TK50 drive? I
could get access to one of these, but a boot floppy would be simpler, 
if it boots then I could try the TK50 at that time.

I'm short of docs (in fact I have none) on the machine, I am going 
to check DEC and maybe DECUS to see if they have anything. I figured 
out the serial console by trial and error, a little pinout help from
the web.
