I thought I'd start a new thread about the UC07 and SCSI2SD to separate it from the RX01 thread which had some of this info in it.
Today I had some time today to install the UC07 I bought on eBay into my Heathkit H11 (LSI-11 with 28kw of RAM and two SLUs) and to build an RT11 v5.7 RD54 disk using SIMH 4.0. I mostly used this thread as a guide (http://www.vcfed.org/forum/showthre...or-installing-RT11-on-a-SCSI2SD-card-PDP11-83).
The UC07 came configured pretty generically. Per the manual, address 17772150 which is 172150 in 16-bit parlance, and BR4. The board has a few jumpers that I can't find definitions for (M-N-P, J-K-L, T-U), but that match pictures I've seen. The board is installed in slot 6 (next free slot).
I configured the SCSI2SD as a single RD54 at LUN0 and wrote the image I created to the card. Then I connected it to the UC07 just so there was a powered SCSI device on the bus.
Not expecting much at first, I thought I'd try to communicate with the FRD on the UC07, but I'm not getting any response. The CPU is halted. I used the following code from the above thread (also on page 5-4 of the manual) to try to access the diagnostics (adjusting the addresses), but the FRD doesn't come up:
@172150/000000 1
@172152/005400 30003
@/000400 42000
@172152/002000
@200g
The board was removed from working equipment, so let's assume for now it works. I'd like to check the following with the group to see if I've gone wrong anywhere:
* is the code above the right way to access the FRD on a 16-bit LSI-11 machine? Is this even compatible with an 11/03 (LSI-11)?
* is slot 6 an acceptable slot position or should I move it further up the chain? In slot order, the boards in the machine are RAM-CPU-RAM-SLU-SLU-UC07-XX-XX (XX=empty). The first four boards are the way the unit was delivered and I have run RT-11 using the TU58 emulator.
* anything else I missed?
Again, any clues would be greatly appreciated. Thanks!
