booting rt11 v5.1 on an 11/45

As I stated in the chat last night, I don't know a whole lot about 11/45s
(or rather, any PDP11s before the /04 in general) but I would recommend
downloading xxdp v2.5 and seeing if that even boots. This is an easy way to
figure out if (a) it's just RT-11 5.1, and (b) if there are additional diags
on the xxdp 2.5 cartridge that might help nail down the problem.
I hope that helps.
