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 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 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"...
