DEC-Digital-1972-GT40-vector-graphics-system-PDP11-PDP-11 http://www.ebay.com/itm/231477915161 If I could afford it I wouldn't sweat the shipping cost. I think someone had posted what board did the graphics. Has that ever been given consideration for being added to SIMH for the 11? I'd love to run Lander, which I think is running on the system as shown. To Al: There was also a system like this at USL, which I wish had been conveyed to you. I suspect it was not. There was a new in the box replacement CRT because someone had had the system halt and burned the phosphor. You had to watch the system and never let the dot stop. If it stopped at a spot on the phosphor in the on position, you'd etch the phosphor. Ours (USL) never ran anything but Lander, so until someone with a project came along, we were saving the tube. The burn didn't affect lander much at all. thanks Jim

Need help: Reading 800 bpi NRZI 9 track tapes

Might check with Al over at CHM - I have been told he has every format known to man covered. Ed# SMECC.org In a message dated 6/12/2015 4:02:26 P.M.

ISO: Sun lunchbox vertical stand

by dave＠661.org

Last year or so someone offered up one or two vertical stands for Sun lunchbox chassis. I put my hand up for one and never heard more about it. Might that original person still have the stands? Does anyone else have some stands available? -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

VAX-11/730 %BOOT-F-Unexpected Machine Check

by cctalk＠beyondthepale.ie

I don't know yet whether there's something not-right about the > contents of the hard drives, or I need to configure something (?) so VMB.EXE > knows what to look for. There can be more than one system root on a VMS system disk, typically one each for different nodes in a cluster, maybe under [SYS0], [SYS10], [SYS11] etc and standalone backup can sometimes be found under [SYSE], if installed. "Unable to locate BOOT file" may indicate that you are not reading the correct system root or it may indicate that the disk is not bootable or maybe something entirely different. I am not well up on the 11/730 and I hope someone more familiar with their system specific details will chime in. On some other VAX machines but probably not an 11/730, the [SYSE] root would be booted by entering something like: boot /R5:E0000000 <device> or maybe: boot /R5:E000000 <device> or maybe even: boot <device>/E0000000 or boot <device>/E000000 > The boot scripts on the console boot tape appear to set up VMB.EXE by shoving > numbers into some registers prior to loading it, and I have not yet located > any documentation about what the numbers mean. If it is like other VAX variants that I am familar with, the top eight bits (or maybe four bits - I forget which?) of the 32 bit number that ends up in register R5 is what selects the system root you end up attempting to boot. > > I wonder if I might be able to back up the hard drives to an absurd number > of emulated TU58 images, so that I could then examine those on my modern > machine? > That sounds plausable.

Wierd reply addresses

by fozztexx＠fozztexx.com

On Jun 12, 2015, at 5:04 AM, Vincent Slyngstad <v.slyngstad at frontier.com> wrote: > There seem to be a number of messages from various folks > where the reply address has been rewritten to General at classiccmp.org<General at classiccmp.org>;Discussion at classiccmp.org:On-Topic and Off-Topic Posts<cctalk at classiccmp.org>; > instead of > General Discussion at classiccmp.org:On-Topic and Off-Topic Posts<cctalk at classiccmp.org>; > > What is that about? Could it be related to me getting delayed second copies of stuff? It happens because there?s some older mail clients being used which incorrectly parse the email address and create the general at classiccmp.org address when replying. The problem with the duplicate messages is because messages from the cctalk list are also relayed to the moderated cctech mailing list, and vice-versa. What happens is the messages from cctalk go over to cctech, get approved, and then get sent back to the cctalk list. From my understanding of the mailing list software being used, it doesn?t have any built-in facility to prevent duplicates by checking for messages with the same Message-ID, and would require someone to spend a little time to cobble a helper script together, but no-one has yet, so the message duplication has continued for a year or so now. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

First VAX-11/730 VMS Boot! (was: Re: VAX-11/730 %BOOT-F-Unexpected Machine Check)

Going back to an earlier version of VMS should help too - V7.3 probably has all sorts of stuff that is more appropriate on a later, faster VAX. > > And at the moment, it's still booting, as I sip my morning coffee.

The filing system is already consistent (that's one of the reasons it's boots so slow...) If you look for a copy of the VMS FAQ on the net, there should be a section on how to reset passwords. Here's a quick summary of one method: Go back to your conversational boot but this time enter: SET VAXCLUSTER 0 SET /STARTUP OPA0: SET WRITESYSPARAMS 0 CONTINUE When you get a $ prompt, enter (carefully, without any typos or you get to start all over again): SET NOON SPAWN /NOWAIT SYS$SYSTEM:STARTUP.COM When the startup finishes, press enter again and you should get back to your $ prompt. SET DEFAULT SYS$SYSTEM RUN AUTHORIZE MODIFY SYSTEM /PASSWORD=<new password> /NOPWDEXP /NOPWDLIFE EXIT LOGOUT Then login in. When you want to shut down gracefully: @SYS$SYSTEM:SHUTDOWN Regards, Peter Coghlan.

Collectors pay big money for old tech

by trash80＠internode.on.net

May be of interest to some list members - appeared in the Sydney Morning Herald Digital Life section yesterday. Unfortunately I'm not one of the big spenders. I know the story about the $200,000 Apple has got a fair airing but some of the other numbers being quoted here frighten me. http://www.smh.com.au/digital-life/digital-life-news/discarded-apple-i-worth -us200000-collectors-pay-big-money-for-old-tech-20150610-ghfmlu.html ++++++++++ Kevin Parker ++++++++++

Need DZQ11 (M3106) Print Set

by jnc＠mercury.lcs.mit.edu

> From: Paul Anderson > OK, I have 10+ of the M3106 and M3107 boards The M3106 is the DZQ11; the M3107 is the DHQ11, a completely different beast (a sister to the DHV11, the quad version of the DHQ11, the dual version). We already have complete documents online for the DHQ11 (UG, TM and FMPS), so no great need for them. Just to recap, what is missing online from the complete set of 4 (DZV11, DZQ11, DHZ11, and DHQ11) is: - DZV11 Tech Man (EK-DZV11-TM) - you have this - DZQ11 FMPS (MP-01795) - still missing, and the thing I'm looking for - A DHV11 User Guide, _if such a thing exists_ (I have no definite proof that it does) > if the print sets are filed under M3106 and M3107 instead of the option > name they might take while to get to. > ... > I'm slowly getting everything, prints, manuals,boards,etc. in order but > it will take time. Understood. Don't push your recovery! :-) > Noel, you are more than welcome to use any documentation. Talk to Al > figure out who needs it first then ship it to the other and back to me. For the DZV11 Tech Manual, that might be best going to Al? I don't have a page-feed scanner, just the manual one (albeit it is large format, and can swallow prints at a gulp), and since TM's are usually lengthy, probably best if someone with a page-feed scanner tackles that one. (I assume Al has access to a page-feed scanner.. :-) Noel
