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.
Dave

Hi Dave,
In my ignorance I incorrectly assumed the DHQ11 was a SCSI controller
because it has compatible centronics sockets. Thinking about the name that
was obviously wrong!
I have two Emulex UC07, one is spare and the other is in my PDP-11. If I
install
this into the VAX Q22 bus do you think it will explode
or work?
Even if this did work it wouldn't be ideal but I'm not sure of any
alternatives at
the moment.
Thanks,
Aaron

Aaron,
Which SCSI card do you have? These systems are normally DSSI systems
not SCSI You should be able to do SHOW DEVICE then BOOT <name>

It allows me to type at this point but does not appear to do
anything with the input.
I've looked through the KA670 manual and found a listing of the
error codes.
5F = SGEC (Second Generation Ethernet Controller) "loopback_type
no_ram_tests"
5C = SHAC (Single Host Adapter Chip) "shac_number"
I'm not sure if it is relevant but I removed the TOY battery when I
got it to prevent it eating everything. I've not taken apart the
console door thing but perhaps it was too late. The SGEC might
refer to the ethernet controller installed on that door?
If anyone is better at understanding these error messages I'd
greatly appreciate any info you could give.
Cheers,
Aaron
Never mind. I think these tests can be ignored, and I got rid of the
SHAC putting the terminator in the right place.
The VAX does respond to my keyboard input... when I have the terminal
set
to
the right serial config.
Need to figure out how to get it to boot from SCSI. It's picking up
my
QBUS
DHQ11 and DELQA cards fine.
I intend to replace the 12v module in the PSU with two small 12v 240v
boards
