This is basically a pdp-11, based on the 11/2 chipset.  Unlike most
other -11s, though, it is configured such that there is 60kb available
to the user (30k-words) and the IO page is only 4kb instead of 8kb

The roms know about RT-11 queue elements and the RT device driver
(PD.SYS) calls entry points in the rom to do the actual data

You could use it in place of your 11/44, if you want to waaaiiiiit
for stuff to get done... not to mention the fact that there really
isn't much space on two RX01 floppies...
