machine language
I am trying to fire up a DN6600 emulator and am encountering some
discrepancies between the DD01 documentation and existing software.
Anyone remember how to program this beast?

I wish that I kept all of the Honeywell docs that I had. I gave most of
what I had to the Boston Computer Museum, so it might be a the CHM.
I maintained GECOS and the front end software on a Level 66, with DN355,
and 716 front ends. The software modifications to the DN355 were done under
contract by Honeywell in Bedford, MA. The 355 and 716s were replaced by a
pair Level 6 front ends. I still have the platter from one of the fixed
head disks from the 716. If I remember correctly, the 16-bit Level 6 front
ends ran modified microcode to make it 18-bits by using the parity bits.

I don't think so. From what I remember, and it?s a long time ago, our DPS/6 front end
ran completely different software. The DN355 ran GERTS or GRTS and the DPS/6 ran DNS...

I do remember we had some LSI/11 based RNP(707 perhaps) "look alikes" which
would drop their connection. When this happened you go the dreaded "unable to contact
GRTS" message....
... some wag added a line to our "message of the day file" which read "who
are the GRTS and why are we trying to contact them"...

The equivalent on an earlier series (some variant of 600) was "no
response from 600". Usually you had already been able to figure this
out due to the 60 seconds of no output immediately preceding.
