Don't know if this will help at all. Not sure if the UC07 and UC17 share the
same firmware and VAX host resident FRD code. On the QBus
UC07 version (firmware version G143R) there is a short stub located at 80h
which jumps to the main code at 280h. (If you have a VCB02 instead of a
serial console you start at 82h which then jumps to 282h and does something
slightly different).
Interesting, the UC17 has the same firmware version (G143R) on the label of the EPROM. I
wonder if the contents are identical. Could you send me a dump of your ROM so I can
compare?
Hi all --
I'm working on restoring a VAX-11/730 at the museum and things have
been going
pretty well thus far. I've been bootstrapping the console and
diagnostics from simulated TU58 (images from:
https://github.com/NF6X/VAX-11-730-Console-v57). All of the TU58-based
diagnostics are passing.
I'm attempting to bring up an Emulex UC17 SCSI controller for mass storage
and
I'm having trouble with it. I thought I'd check with you guys to see if any
of you have seen this issue or have any idea where I might be obviously
going wrong before I start digging deeper into this.
The current issue is that I can't get the UC17's built in diagnostic/utility
(referred to as the 'FRD' in the manual) to run. I am following all of the
steps
to the letter (see the manual here
http://www.mirrorservice.org/sites/www.bitsavers.org/pdf/emulex/UC175
1001-C_UC17_Dec90.pdf, pages 71-79 (section 4.5.7)) and I'm getting the
right values back when examining the SA register during the process, but
executing "S 80" halts after a second or so with:
?08 PC=00000298
Which is an odd way for it to halt, 08 means "No user WCS" according to the
11/730 user's guide.
Here's the full conversation, just in case:
issue on it, in an 11/44 we have here.

I've confirmed that the issue isn't with the card, I can run the FRD without
I dumped the memory for this code from the VAX and entered it into SIMH
to use SIMH as an VAX unassembler and this is what it looks like.
If the UC17 host resident VAX code is the same, any clues here as to what
might be causing a halt on the 11/730?
The values in/around 298 look to be identical, but I haven't dumped everything in
memory. I'll poke at the code, do some disassembly and see I can figure out
what's going on...
Thanks!
Josh
