Yup, I have previously had RT-11 running on this machine without incident.

Yep, got that in there.

Easy enough experiment to try; would need to re-jumper the G740 disk selection flip chip in the RK11-C too, I guess?

Only a DL11-W in this system.

Ah, haven’t checked that one yet.  I will carefully check my basement for squid!
