Why the hate for the '52? ;)
What's the OS yours is running, that is with SIMH on it?
Non-up-to-date Raspbian. ;)
Hello!
The only one I saw was being used for something else?..
Was it being used as a place to sit coffee?
Ah crap, that was mine, sorry..
You need a VT05?if you don't already have one. ;)
I don't have one, and likely never will. One got exhibited (it belongs to
Mike Ross) along with my PDP-11/70 at VCF-East last year, though.
I have several VT52s, and a couple of VT50s.
(and I was actually talking about my coffee above..)

You need a VT55. Good luck finding thermal paper for it though. ;-)
We bought 2 new (old stock) VT55's in the early 80s. They were kind
of fun for graphs, but not worth what the school paid for them.

To me that's the pinnacle of emulation. Connecting REAL peripherals to an emulator to get close to the REAL experience. I did a bit of testing of Mark Pizz's serial port code for terminals against my VT510 just because I wanted to be able to do real, direct serial terminal work against an emulated VAX or PDP-11 and so I made sure it was tested some so it got into 4.0. There's something rewarding about rattling away on a VT510 talking to a tiny board that draws a lot less power than the VT. :)
It is indeed rewarding. :)
The RaspberryPi is great for lower-end VAX and PDP-11 emulation. It only musters about 1-2VUPs at best running the uVAX 3900 so isn't a huge deal faster than the early 11/7xx series machines. Still my Area router is a rev. 1 Raspberry Pi running raspbian and SimH. It's been running 24/7 for almost a year :)
It most definitely is. I chose VMS 5.2 for a reason. ;)
mark at raspi1:~$ uptime

We get occasional power outages (hence the short uptime) and I never got around to buying a UPS (if my computer stack goes off I just grab a torch and read a book and wait for the power to come back :P).
How long are the outages usually? (I have some UPSes and some generators. Basement floods if power is out too long)
I have 2 more RasPi's in the 5.25" bays of a 2U unit now too, one that will be running as a PDP-11/93 and one that will run as a VAX 11/780. They share the 2U with a Atom D410MO motherboard that will run my VAX work machine (it's about 20x faster than a RasPi). The thing is jury-rigged so the Pis run of the 5V line on the ATX PSU via a Molex. It has a GBit hub inside and 2 NICs on the Atom board (alas only 10/100) that are bridged so it only needs 1 ethernet port to attach the whole box. It's neat and save for some soldering, I built it myself. I originally built it for hosting a VAXcluster but I really have no use for one.
That is an awesome setup.

Oh, incidentally, Gregg, the Optiplex is probably round that way so it keeps him warm at his desk.
If that were a desk, that would be true. ;)
I have an ancient (well 2004-ish) P4 3.0 HT that I use for Windows XP 32-bit now I'm on Win 7 64-bit (I have legacy hardware devices that don't have any 64-bit drivers). It's a Dell Dimension 4600 motherboard that's been reboxed with a new case and PSU with a cute ducted cooling fan for the P4 made of plasti-card, duct tape tape and a 120mm fan. Which reminds me, I must put Pathworks32 on it this week :)
Personally, i'd run NT 4 on a P4 (shame it doesn't seem to like HT P4s ). I prefer it to XP. ;)

I don't. I generally don't work on gear THAT old. (not for any particular
reason other than lack of opportunity and focus on high-end test equipment)
The alpha isn't old enough to be interesting and the
VT420 is too recent to not be overshadowed by cooler terminals. My
"classic mac" gear is from the mid-'90s and isn't that exciting.
There isn't an Alpha in existence that's old enough to be VCF material.
Maybe if I get VMS 1.x working in SIMH...
That might be neat.

Hello!
I know. Going to do a repeat performance on your PDP-11 setup this
year? (And this presupposes we are good for the VCF.)
This year?? There's no VCF-East this year.
Next year...probably not, as I've already exhibited it. I'll pick
something else. Any suggestions?
Maybe one of the DEC-20s. Unfortunately that still leaves the issue of finding a MASSBUS drive. Perhaps we could do a low-speed WAN cluster of TOPS-20 if the older versions had those features and would run on your 202s. I'll need to go read the manual again I forget what it's called but I recall TOPS-20 having some cluster-like features...
That would be awesome, but finding a MASSBUS drive is proving difficult. :-(
Yeah. :( I'll let you know if I ever run across one. I've run across weirder.
That you have.

Hello!
There isn't? Oh <DELETED!>. Oh anything that can think for itself and

Hmm.
Maybe for next year I'll work out something. If I can manage to find
the room for my crazier then out beyond left field ideas.
That would be amusing. :)
