The _at_ is the ODT prompt.

If you type a / that prints the contents of the current address
and if you enter a number it will replace it.

_at_$n (n=0 to 7) prints a regiters contents and can alter it.

_at_1773000G Start executing at 773000 (octal!) That address is commonly
the address of rom bootstraps.

RT-11 is available on the net at...

ftp://gatekeeper.dec.com/pub/digital/sim/software/rtv53swre.tar.Z

That is a unix gziped tar file of RT-11 V5.3.

If you find it on media you are permitted to use it as a hobbiest.
