I thought 2780 uses BISYNC, which is a different protocol. X.25 is HDLC. Yes,
both need modem eliminators -- like an async null modem but an active device
that also supplies the synchronous bit clock.
X.25 (and I think HDLC) is indeed asymmetrical. Whether that can be gotten
around is not en
Hi Dave,
I have been involved in a project using VAX-2780-3780PE and have been able to
connect two VAX’s together using a Black Box Synchronous Modem Eliminator ( SME
).
Product code: ME204A-F.
No VAX PSI involved.
Needed Decnet Plus and Wan drivers.
Was able to test using a utility that comes
Here is a pointer to a number of different basics.

Porting VAX Basic... Sort of...
I have a program that does a bunch of the work to conovert VaxBasic to C++,
but it doesn't do everything. There's a lot of stuff that just doesn't
exist on other OS's, like the SMG, RMS, LBR, etc.

Well, the QVSS device is monocolor, so you shouldn’t see any color. The QDSS
device was multicolor.
If the “set cpu model= vaxstationgpx” seems to enable the qdss (multicolor)
device instead of the qvss (monocolor) device, then you should be setting qdss
(multicolor) capture, not qvss.
Note that
Very interesting. With "qvss capture" below "cpu model", mouse now works
(jumpy, but better than no mouse). Also, I am getting console replies at
the top of the graphical desktop, and have lost color. Here's a screenshot.

I know almost nothing about VAX PSI, but I have a vague idea
that even though X.25 is asymmetric and intended for DTE to

Hi Mark,
At first we just used PSI that talked to a DUP-11 in a VAX-11/780 and later
a 750. The DUP-11 then talked to a modem, and thence to the JANET academic
network in the UK.
Later we used PSI-Access which talks directly to Ethernet. At least that is
how it appeared to me.
Your point about b

Wow, I have not heard of that package since the late 1980's. As I recall it replaced a physical
"PAD" with a software defined one that ran under VMS and used an X.25 port to
communicate. We had one run
yeah I kinda doubt that.

I work code using indexed files and could even index off of arbitrary text in a

I know of no other solution that can do this.
its because vms was doing all the heavily lifting behind the scenes.
I could do a read base
Shouldn’t the configuration order be:
set cpu model=vaxstationgpx
set qvss enable; if required – I think ‘set cpu model =
vaxstationgpx’ does this implicitly
set qvss capture
There may be some odd interaction if capture mode is enabled before setting
vaxstationgpx.

The potential real revenue stream from VAX users with hobbyist licenses is
small, but HPE should be able to put a significant dollar value on the Good
Will generated by issuing perpetual licenses.
Historically the sales and marketing people at DEC, COMPAQ, HP and HPE have
placed no value on cus
Let's say you had the PAK(s).
You could then install the software. Then what?
That software connected through some hardware to something outside. What
hardware was this and what did it connect to? I'm pretty sure that the
hardware in question isn't simulated primarily due to the fact that an
I have been able to replace RMS indexed files with BerkelyDB without many
issues so that is one alternative. Just have to replace I/O statements
with functions that do the appropriate calls.

Hi folks,
Back in the day (mid to late 1980s), I was the system manager of a
VAXcluster. I have been recreating the experience using simh, which I find
to be excellent. My system manager days finished with VMS 5.5-2, although I
also have emulated systems running both earlier and later versions of
I built the latest SIMH microvax2 on FreeBSD and found the behavior is exactly
identical on FreeBSD as well. The problem is not Linux specific.
Any ideas?
