I'm trying to use a simulated RX02 disk (under simh) with RT-11
and can't seem to get the DY driver to install.

Here's the relevant log:

sim> set ry enabled
sim> att ry0 ry0.dsk
RY: creating new file
RY: buffering file in memory
sim> c


.install dy
?KMON-F-Invalid device installation DL0:DY.SYS

.dir dy.sys

DY    .SYS     4P 20-Dec-85
 1 Files, 4 Blocks
 14841 Free blocks

I've tried with 2 different software "kits", the one from the simh site
and the one from bitsavers.

Any ideas?

Thanks, Don
