That's certainly possible, and sounds likely...just an older one. I wish I still had that tape, but sadly it was lost many years ago. Distribution tape for 4.1? I thought you had 4.3 anyway, so what would you use 4.1 for? I wouldn't...but it was a pristine, original DEC RSX-11M distribution tape, and those don't exactly grow on trees. Oh. Ok. There's also a sentimental attachment; it was mine when I was a teen, given to me with my first PDP-11. First question: I'd like to try to get DECnet running on this system, if possible, to get it on HECnet. I've never run DECnet under RSX before. I could put a DEUNA in the machine, but I am running short of slots. I have a DELUA, but I don't recall sysgen asking about DELUAs. Are they compatible at the driver level? Meaning, if I re-do my sysgen to include a DEUNA driver, will that work with a DELUA? DEUNA and DELUA are the same from a program point of view. They have different microcode, but that is detected at runtime, and the right microcode is loaded. The rest work the same. They use the same drivers, both in DECnet and in plain RSX.

VT320 issues

by b4＠gewt.net

Did this email send previously 4 times? I never got a response nor did I get my own email, so apologies if Exchange being the dumbest mailserver ever has caused you pain and suffering in the form of repeated emails. My VT320 decided to fail last night. It was running fine, I stepped away, returned to it off and repeatedly clicking/ticking. It sounded like either a stuck relay or the flyback arcing. The screen would occasionally flash and the current draw would fluctuate between 2W and 17-25W until it eventually turned on and ran fine. Any theories? Should I distrust the VT320 or was it just something like a stuck relay that's older than me? I grabbed pictures of the board but they never seemed to actually get anywhere. http://www.youtube.com/watch?v=aSCpQzoGHZc is a video of it powering up. Is that normal behaviour or is something wrong? -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

SAMPSACOM Wishes Fellow DECHEADS a Merry Xmas! Virtual machine giveaway..

by wonko＠4amlunch.net

I wouldn't mind one for the tunnel stuff and other projects. I think I'm going to let my OVH box go. The network performance they offer is terrible. -brian On Dec 24, 2013, at 3:41, Sampsa Laine <sampsa at mac.com> wrote: Guys, I'm about to migrate all my stuff into a data centre with a symmetric 1 Gbps pipe and the server I'm hosting on is pretty chunky, 16 Xeons at 3 GHz and 64 GB of RAM. Anyway, I'm happy to slice of off five or six VMs for people who need them with the following features: - Real static public IP address, with up to 12 port mappings (tcp/udp) from the outside - 100 GB disk - 1 Xeon CPU - 1.5 GB RAM - Full root access to your VM - SSH (pubkey auth only) account on the VM host - VNC access to the console via SSH So if you have a project in mind that could use something like this, feel free to fire me a personal email (to sampsa at mac.com) and I'll probably roll out a VM for you (the migration will only happen mid-late Jan, but I can arrange slower speed access and control for those who want to get started early). sampsa <sampsa at mac.com> mobile +20 11 2150 2266

If you have a brusys.tap file, would you please send me a copy? I can't seem to find that anywhere. Did you try booting the BRU64K tape? Sounds like that should be a BRUSYS system as well. Not sure what the correct name is. I know it by BRUSYS, but there might be some slight difference between the 11M and M+ standalone BRU, or it might just be different versions of the same.
