PDP-11/03
1/10/03
I acquired an 11/03 (it was cheap). I've also borrowed enough Q-bus
cards that I can test out the RL02 drives that I have (total of 4).
I also have a copy of RT-11 on an RL02, so I'll be able to test out the
RL02 drives.

After messing around with RL02 cables and cleaning the drives up some I
did manage to get RT-11 to boot on one of the drives. The second
drive I tried made nasty sounds when it tried to spin up (fortunately I
put a "scratch" pack in the drive before I tried to spin it up).
When I took the pack out it looked like it was scored -- I guess that drive
needs some work. The third drive I tried worked too. The fourth
drive I knew needed work so I wasn't prepared to try that one out.
This is great! I seem to have two working RL02 drives. So now
atleast I can do pack to pack copies and initialize and check out packs.

Over the past few days a number of the Q-bus cards that I've ordered have
shown up. So now I can build up the 11/03 with my own set of boards
and can return those I borrowed. Here's what's in the 11/03 now:
| Option |
Module |
Description |
| KD11-HA |
M7270 |
LSI-11/2 CPU 16-bit |
| MSV11-DD |
M8044-DB |
32K Word 16-bit MOS RAM |
| DLV11 |
M7940 |
Serial Line Unit |
| RXV21 |
M8029 |
RX02 floppy disk controller |
| RLV11 |
M8013 |
RL01/RL02 disk controller (1 of 2) |
| RLV11 |
M8014 |
RL01/RL02 disk controller (2 of 2) |
| BDV11 |
M8012-YA |
Bus terminator, bootstrap and diagnostic ROMs |
I put both the RXV21 and the RLV11 in the 11/03 because both are limited
to 18-bit addressing which happens to be the same as the LSI-11/2's limit.
Right now I have one of the RL02 drives connected to it, but eventually
I'll have the RX02 drives connected and the RL02 will be put on one of
the bigger 11's.
