So, I may just be spoiled from using RSX11M-PLUS and now expect too much
from the RSX11M OS. But it seems to me the CLS command would be a
nice-to-have, but I am not able to find anything about it. So did that not
exist for RSX11M? How does one clear the screen in that environment?

From postings, I know that folks use the RP2350 for interfacing; the trade press has been shipping news of RP's rev A4 datasheet in volume.
The datasheet should tell all. However, the 5V tollerance of the "IO" pins is significant for its simplification of TTL interfacing; the maximum supply and output voltage remains 3v3. See section 14.8.2 (p 1335) et seq - NB the FT indication.

I tried to contact rsts.org using their web site form, but it threw a
server error when I tried.
I have two pieces of info for them, if they hang out here:
1) The files at
http://www.rsts.org/autoindex.php?dir=distros/RSTS_tapes/V_10.0/ and
http://www.rsts.org/autoindex.php?dir=distros/RSTS_tapes/V_10.1/
cannot be downloaded: access Forbidden error.
2) I have a product code for the RSTS 10.0 distribution tape (they say
"Unknown DEC Product Code" on the index page.)
The code on the actual tape is BB-P016P-BC RSTS/E V10.0 INSTALL 16MT9
(Unfortunately, my tape has not yet responded to my attempts to read it
- I think the signal that ought to tell the drive it is 1600 BPI PE
isn't being recognized by my HP SCSI tape drive - it thinks the tape is
800BPI, but it works OK with other 1600BPI tapes.)

Hello,
I am a collector of old computers and a fellow owner of Datamaster
computers.
I have seen your CCMP post about wanting to have image output from your
5324.
I imagine this computer hasn't been serviced. If you want I could help you
to solve both issues.
If you still have the computer and want to do something with it, we would
first need to diagnose and repair it if necessary. I would guide through
the entire process of troubleshooting.
After the service, I would instruct you how to get video output through
HDMI.
Regards,
Jaume
Hi all,
I just spotted an auction on eBay for 40 IBM SMS cards.
It sold for over $2,000 (!)
Does anyone know if this reflects collector value or the value of the
gold content?
Also, what’s the current value of a set of SMS cold contacts?
Thanks,
Henk

Greetings,
Been a long while since i have posted in on here. I usually discuss my pdp 11 and vax systems. I have decided to pivot my career to scada syatems. The company i am with has some interesting stuff that goes pretty far back. Our custom in house tech is a plc pump controller with a radio connection for data logging and control. Pretty cool, 8051 based, with a version of basic in rom that has scada functions added. The backend servers are just linux systems, although in a modular backplane for easy replacement.
I have not read much about this tech outside of what we have in house. Are there other historic scada system computers or technologies that are similar, easily found on ebay for example?
Ive seen some mention of old allen bradley stuff, but not much notes on how it would be used remotely in the field, as a remote terminal unit.
Any suggestions are appriciated, trying to read more into scada tech outside of my company's tech.
Thanks,
Devin D.
Honeywell made a large number of these systems, which were in use in
many industries (oil refining, manufacturing of all types, water utility
distribution, etc.). They were quite expensive, and PLC manufacturers
have made great inroads into that market in the past couple of decades.
As a result, some of that equipment is showing up in the surplus market.
I found a Honeywell "Orion" console desk being disposed of that I would
have loved to take, except that it was truly massive (it must have
weighed nearly a thousand pounds!). It was electrically height
adjustable (with memory), had mounts for two very large monitors,
integrated lighting, cable management, and rack spaces for physical
buttons and lights. Actually, a lot of their equipment is pretty
massive, especially when compared to current-day PLCs.

There's been discussion of this on the VCFed forum, but it doesn't look
like anybody's brought it up here yet. Per Mike Brutman, list member
Chuck Guzis a.k.a. Chuck(G) passed away recently. He was highly
knowledgeable, a full-bore storage expert, and an all-around even-keeled
decent sort, and will be missed.
(forgive the dual post with Midatlantic Retro if you're in both groups....)
Hello
I have been in my spare time messing around with NeXT hardware and I have
built three extra working NeXT cube systems (mouse keyboard, computer,
display) that I would be willing to let go for less than Ebay prices (look
on Ebay for sold status complete systems). Two of them have SCSI2SD hard
drives and I have one that still has a working original drive. I don't
have any optical disks available, but the optical drives come with the
system, untested. There are always caveats to define "works", but
basically these are working computer systems that could be connected to a
network and they come with a basic Next OS installed.
I don't want to ship these if possible. So if you're willing to pick up
the system (Landenberg, PA), you can try before you buy and pick the one
you want at a discount to Ebay price. Contact me through
kennettclassic.com/contact.cfm with your offer/timeline. FIrst come first
served.
Shipping is available if you want to pay a shipping charge, plus postage.
I have shipping boxes. I am going to VCFMW this year, but I am flying
there and won't be able to bring them. If you want the cube system
delivered to VCFMW, you'd have to find someone to deliver it for you, or
have it shipped. I am willing to deliver a system a reasonable distance
from the Phila/Baltimore area.
Cash, CC, Paypal, check accepted.
