Hi all, thanks for your help with my earlier questions.
I'd like to set up several vax780 instances and run uucp (over TCP)
between them using one or more of the simulated DZ lines. But I want to
use the remaining DZ lines for logins.
Is there a way to set some DZ lines into 8-bit mode but keep t
Warren,
We can take this offline. The quick answer is as far as simh is concerned
leave everything as 8 bits.
I'll show you how to make the rest work properly. The logins will run 8
bits also, but will run with parity enabled which BSD will handle just
peachy.

Folks,
Hmm. I checked TOPS-10 7.04 monitor source codes and found two files about
SCS/SCA packet info but did not find any files about CI interface.
I think TOPS-10 can communicate through DECnet.
I think that transport layers are SCS/SCA layers.
There is commercial emulator (Charon-VAX) em

The CI interface is the KLIPA. Its a KL10-only device that sits in an
RH20 channel slot. It uses a port architecture similar to the CI780,
with queues and 36-bit pointers in physical memory. It's supported in 7.04.

From the tops world, DNADLL.MAC, common to tops-10 and tops-20:

If you configure ethernet, I'd expect that would "just work". Not being a VMS
user I haven't tried this.

I don't have time to dig up the details. But TOPS-10/20 definitely
supported the CI. It turned out not to be used much since IIRC despite
the high wire speed, thruput was better on the NI. But the rationale
was something like if you had CI connectivity for storage, and an NI

The simh VAX simulators will readily participate in LAVC clustering with
other simh simulators and/or real VAX systems as long as they're all present
on the same LAN.

Quick question - I saw SDL graphics support mentioned somewhere and wondered
which emulators have graphics support? Do any of the VAX ones?
Can I run native DECWindows on any of them?

I assume you mean were not supported on the VAX UBA. And that would make
sense.

I used DHV11s on Microvax II when they we're real hardware. Worked fine under
VMS. I imagine DH11 wasn't different enough for them to not work on unibus.

There were 3rd party Unibus to Qbus converters that would handle the signal
Mux/decus issues on the bus lines.
I never saw any on 11/780 class boxes.
Crappy UBA was slow. Most were used to
put Unibus peripherals on Qbus Vaxes.

Interesting. That sounds like a product-specific item rather than part of the
standard architecture.

The Qbus-based VAXen support the QVSS (black-n-white) video module cards, which
were the basis of the original VaxStation I and were also compatible with
VaxStation II's, III's, and 4000's. The SIMH QVSS uses SDL for visualization.
This is a native DecWindows interface.
To be honest, it's just

VAXwindows was a layered product (like just about everything DEC sold for
VMS). Without it a VAXstation of that era wouldn't be very user friendly,
but it would boot happily
