Apex Electronics (surplus) in Sun Valley has at least one CDC
Plato terminal out in the junk/scrap area. It's a ruin, though
likely complete. CRT is pushed back in the case, you can see the
touch screen junk. Rain and sun soaked. It's out near all the
other historic terminals, all ruined (Beehives, DEC stuff, all the
old brand names) in a heap with scrap and dirt and rain.
Too bad!
Ok all you 'vark fans, you can't pass this one up!
http://www.simpits.org/~geneb/ef111/ef111.html
I don't own it (unfortunately), but if you'll email me off-list I'll put
you in contact with the owner. The cockpit has been ejected and as you
can see is in remarkably good shape.
The owner has also made a preliminary identification so whoever ends up
with it can get the history and redacted accident reports from the USAF.
(No he can't ship it to Australia. Sorry Rod! :) )

Maybe it's due to I have never attended a hamfest, but I agree with

A friend came across a DECMATE I and we have been playing with the
beast, but are unable to figure out how to get a system loaded
without the necessary floppies for the RX02. It talks nicely to my
VAXStation 3540 as a VT100 (DP278A option), but it looks only like a
terminal.
I've Googled DECMATE and am totally FAQed up with the history and
long lists of software with little in the way of description. Is
there any runes to cast or incantations to key in so that we might be
able to load in a system over the RS232?
Any help will be greatly appreciated.

Essentially the layout would be this. I have a computer with 4 internal
modems in it. Has to be internal, I can't do this with external
modems/serial ports. Somehow I get it configured so that I can telnet from
the internet to this "emulator" and it directs my telnet session to one of
the 4 free analog lines.
Now, there's some solutions like lantronix UDS devices, where the device has
an ethernet jack and a 25 pin serial port and it can be set to emulate an
external modem, so folks can telnet to this device and it then tricks the
computer into thinking a modem connection is made...
...but my scenario is different in that I want the connection going to the
PC to still be analog lines. So, this device would have to have some sort of
modem emulation of its own.
It sounds sort of off-the-wall, but I wanted to run it by the group to see
if it rang any bells. Maybe there's some situation where such a device
would have been developed, but I'm not seeing the connection yet. Perhaps
if you were putting a multiline BBS system (that didn't support external
modems) on a local LAN? Maybe that's stretching the boundaries of sensible
communications a bit :)

>>In telco parlance this is what's called a "hunt group"
Yes, thanks, I couldn't remember the right word for it.
One could use telnet from the outside to hit a specific port on the gateway
PC (105.27.33.33:2020 for example for the main line). Each port relates to a
specific path through the gateway to a classic machine or to a "random"
server. The routing software on the gateway wouldn't be trivial, but
wouldn't be too tough either.
I'm also thinking about dial-out from an exhibitor display to a BBS in
addition to a "dial-in" from the outside.
Time to hit eBay and search for a Panasonic 616 :-) Sold commercially, used
units go for $450. The 308 is about $300. I'm obviously looking to pay
less...

In telco parlance this is what's called a "hunt group", where you have
multiple destinations in a group that all have the same function where it
doesn't matter which one you reach (for instance a customer support line).
So you have one number assigned to the entire group, and the PBX will pick
the first available extension based on some simple algorithm (hunt from
top down, bottom up, least used, etc.)
In the VCF exhibit, my thinking is that each exhibitor is assigned an
extension, and so people on the outside (or inside) can call into a main
number and then from there transfer themselves to a particular exhibitor's
extension. If there's a TCP/IP to telco gateway (what we are discussing
here) then the gateway PC would have a bank of modems connected into the
PBX and anyone coming in on a TCP/IP "call" would be randomly assigned a
physical modem, and from there they could dial into any available
extension. If the extension is busy, they try another (or get routed to
e-mail to leave a message ;)

Just curious...has there ever been a device available to anyone's knowledge
that functions like an analog phone line and allows transmission via TCPIP?
For example, taking an older BBS system that has 5 internal modems in it,
and plugging the lines into this "mystery" device and then being able to
telnet to different ports and it makes the connection to one of the ports?
I've seen the UDS-10 device from Lantronix to emulate a serial modem, so
essentially you can telnet to it from another PC and it fakes the computer
into thinking someone's "ringing the phone, etc...but I want to take it one
step back...leave the modems in place but emulate the phone lines.
If it rings any bells, or if someone can think of a scenario this might be
needed in, please drop me a note and maybe it'll help me track down
something...
Thanks!

Thanks a lot for your offer, but I have three copies of DR DOS 6.0
(9/91 original English & Spanish and 4/92 "Bussiness Update" for
Windows 3.1)
and a set of patches (3/93 for WfW 3.1). Actually I'm interested in the
latest issue of DR DOS 5.0 (2/91 or later) only.
Diego.

You're description is based on a remote telnet inbound connection
where you're coming in over the internet and using the host PC and the PBX
to route the call to the right one of the four modems on the computer from
the original example. In this case I agree with you -- it's one inbound
connection reaching one destination.
I was talking about the VCF exhibit, where I believe you would still
need a modem bank. If I have two Apple II's each with a modem plugged into
the PBX and I "dial" extension 101 which is the host PC, won't I get a busy
when the second Apple dials "101"? I think you do need a modem bank on the
host PC with the fallover feature on the PBX programmed properly. The PBX is
simply acting as the "phone company" for purposes of connecting the two.

The modem bank off the host is not necessary. The PBX solves the
multiplexing problem. You have one modem on the gateway PC that is
connected to an extension on the PBX. It can then dial any one of the
other extensions which will then connect it to one of the modems on the
target PC.

That stuff is really common if you know where to look ;)

Next time you watch "Field Of Dreams" listen carefully to what's said
"If you build it, HE will come."
Very subtle, but significant difference in the meaning wrt the plot.
