VAX 4000/300 start up / KA670 issues

Mon Sep 14 10:33:04 CDT 2020

Aaron,
I believe a UC07 should work in a 4000. The manual says :-

http://www.bitsavers.org/pdf/emulex/UC0751001H_UC06_UC07_UC08_Host_Adapter_T
echnical_Manual_Nov90.pdf

CPU Compatibility
The UC07/UC08 is compatible with the Q-Bus used on all DEC LSI-11 arid all
DEC MicroVAX II, 3XXX, and 4XXX series computers.

You should really use a -III but I think that the only difference is the
shielding and cable termination. I would expect the disks to show up as DU2n

http://www.bitsavers.org/pdf/dec/vax/4000/EK-337AA-TI-001_VAX_4000_Model_300
_Technical_Information_Mar90.pdf

page 1-12.

You might need to tweak the q-Bus addresses.
