I've got
RSX-11M and XXDP RL02 packs, and can boot from either. I've
managed to make a bootable XXDP floppy diskette. I can boot the machine
directly off of the XXDP floppy on power up. I can boot the XXDP floppy
from the XXDP RL02 pack, and then boot the XXDP RL02 pack from floppy.
However, if I power up and boot from floppy, I can not boot the XXDP RL02
pack. Is this because the Boot ROMs don't support RL02's?
Which version XXDP+ are you using? Does anyone
have any instructions for a Dilog DQ606 controller? I gather
that it can be configured to act as several different floppy drives. The
drives that came with it are labeled as being a RX-50 and a RX-33, yet
RSX-11M sees both as RX-02's. I'd like to get these changed back to RX-50
and RX-33.
I don't have the details, but every DQ606 I've ever seen is MSCP
emulation (DU: devices). I'm surprised myself by the fact that it
could somehow be switched to RX02 mode. Is it really responding
at the standard RX02 CSR of 17777170? I've also
got a PDP-11/44 that I'm slowly working on restoring. It's in
two racks, one has a pair of RL02's which have been cleaned up. The other
has the CPU, 2 RX-02's, 2 TU-58's, and a battery backup. In looking at the
CPU, it looks as if it has a LED for the battery backup.
The DEC battery backup systems that I own for the 11/44 don't have
a LED anywhere on them. Where is this LED? What's the "Hnnnn" number
on the battery backup box you have? No. The 11/44 will run just fine without it.
GOOD!
Thanks,
Zane
