Don't ask any specifics, I don't know them, and I've not seen the system. The Hillsboro "Wacky Willies" currenty has a largish HP system in back (you'd have to ask about it, I was in there yesterday and didn't even see it as they've blocked of the entire back half of the store). From what I was told it's at least one 19" rack, and bunch of terminals, lots of documentation, and I think tapes. I gather it might be something like a 735? Again, I know nothing about this system, someone I know that messes with DEC and Sun stuff spotted it and thought I might know someone that's interested. He said it's *over* a pickup worth of stuff!

Convex Mini-SuperComputer

by mew_jac＠swbell.net

If any of the serious Big Iron collectors are interested in a Convex there is one being decommissioned in Houston. This will be a large hall. If no one picks this thing up it will sit in the Houston weather for a year or so and be melted down. This is the second Convex I've run across in the last few months, surely not many more left. If your serious about moving a few thousand pounds of supercomputer Email me for the details. --

AS400-C10

by thompson＠mail.athenet.net

The above item fell into my possession today. It appears to be circa 1990, contains three hard disks (or DASD, if you prefer), a 150mb QIC tape drive, and a twinax interface card. The IBM web site indicates this machine supports a whopping 20MB of RAM and 2GB of hard drive space. It still has an OS on the disks if I can remember which drive went in which bay in the machine (or if the id is in the drive rather than the backplane) The IBM site is not forthcoming on additional details on the machine.

[ClassicCMP] Does RSX-11M 4.0 support MSCP drives?

To > the best of my knowlege RQDXn are interchangeable Maybe it depends on the firmware then, but I can assure you that the bug certainly exists, and lots of people other than me found it and suffered >from it. The particular bug is that the RQDXn (and other MSCP controllers) return some flags in the top 4 bits of the SA register during initialisation. On the RQDX1 and RQDX2, the rest of the register contains zeros, and the driver code depends on that -- IIRC, there are three places where it does a BNE on the result. The RQDX3 of the same vintage as 5.01, however, returns the interrupt vector in the bottom bits of SA, so the BNE doesn't work as desired. Actually, there's slightly more to it than that, but that's the basics. -- Pete Peter Turnbull Dept. of Computer Science University of York

May even be good enough to discuss the collection, restoration, and sharing of knowledge about classic computers. I have been on this list since mid-97, and Zane & Chris probably just as long, if not longer. We all know that we don't need '[ClassicCMP]' in the subject line since we have done without for this long. I for one will not debate it beyond this one posting, because it being or not being there makes no difference to me. I might suggest that if there are those wanting to debate it further and if Jay is willing, then set up another list classicmp-admin and discuss away. Meanwhile back at the ranch, I took the trash from my wife's shop out back to the dumpster. I noticed a mouse (two-button, not four-legged) in the dumpster. That led to a keyboard and on to a 386 PC. I know, I know, whoopee! Hey another spare mouse, keyboard, floppy drive never hurts. And there is a small chance that I will soon be hauling home a stack of DECstation 5000's and associated goodies. And one last soapbox point. I do not recall any postings yet, thanking Jay for all the efforts with regards to the list. Given all the flak, I would probably have used the ON/OFF switch by now. Why don't we flood this list one last time with some words of appreciation, and then you can tell all of us about your latest finds, etc. Mike Thompson

[CC] Tags are great

by mac＠Wireless.Com

Actually, folks, the software is -not- so stupid. What happened was that I put on my -personal- subject: line the string [ClassicCmp]. Then Jay added first ClassicCMP then [ClassicCmp]; these are in fact different. Notice: Re: [ClassicCMP] Re: ClassicCMP Re: [ClassicCmp] Tag requested in Subject If people had chosen to be observant, they would have noticed -no- other subject had multiple tags inserted, even when following-up. This is the way it should be. The linux-usb, bsd-usb, and irda lists all use tags, and are very helpful. Again, I don't see what the issue is for inserting [C] or [CC] at the beginning. As for this robbing people of 4 characters on the subject: line - gimme a break! (Or should I pop into flippant mode: what, -you- don't use 132-column screens to read your email!

It took me ages to >trace the problem and fix it :-). MSCP support was added in V5.0 -- but there were some problems, not the least of which was the fact that it setup the interface such that if you didn't do any disk access for a minute, the disk would go off line. This was corrected in a patch for V5.0 and in the distributed V5.1, at which time it also worked with RQDX2... support for RQDX3 and other similar interfaces wasn't out until V5.2...

My request-for-enhancement is: "do something" about HTML, or better still, "do something" about any "multipart/alternative" posting (which would include M$ richtext, with those application/ms-tnef attachments). Options I can think of: a) silently discard any such postings (probably not a good idea) b) bounce them back to the author, with an explanation of why bounced c) remove the non-text part d) combination of (b) and (c) e) accept, but warn the author (who may not realise (s)he's sent HTML) All of these would involve scanning the content to a greater or lesser extent. I've no idea how doable that would be with majordomo, whether the extra processing is acceptable to the server, or whether Jay has the time to do that. Just for information, some of these policies are implemented on our helpdesk at work, which automatically tracks, redirects, and archives user support enquiries. We implement (e) on the first "offence", and (b) thereafter, but since every incoming email is read by a human, we do it by paw and memory, and occasionally discretion (ie we tend to discard fewer mails from professors than students :-)). We also have a policy of discarding attachments (or indeed any message) by simple automated truncation at the 10-kilobyte mark (mainly to prevent filling mailboxes and archives with "why doesn't this 4Mb PostScript/JPEG/Word document print?"). I think the record idiocy was a 63MB Word document ("I can't send this document to my friend. Why?") -- Pete Peter Turnbull Dept. of Computer Science University of York

Oh, I forgot to tell you, there is a disk in the software pile called EMULATE. It will allow you to read and write several other computer disk write schemes (Kaypro, Osborne, Cromemco, Tandy, Magnolia, CDR, Z-37, Z-47, Etc.). The disks need to be the same media (Hard Sector or Soft Sector) but it works pretty slick. Mike

FOr example 3100s(early) cant have a boot device more than 1.07gb but data devices can be much larger. The problem was a artifact of early SCSI implmentations and not VMS limits. Since VMS allowed (even before V5) things like bound and shadow volumes to create terabyte sized disk fields I can see a limit for practical systems. Allison

Disk size limits in VMS 5.4-1?

by cmcmanis＠mcmanis.com

I have a very perplexing problem. What I want to do is mount a Seagate ST410800N on a VMS 5.4-1 system. The hardware is a VAX 4000/300 with an Emulex UC-08-III controller half of which is in MSCP mode. (the other half is talking to the tape drive) There are two existing 1GB (Imprimis) drives on this system. First attempt: Put the drive into the SCSI chain, terminate it correctly, drives are targets 0, 1, and 2. The new drive is now target 0, the others are moved to 1 and 2. I reset the VAX and get into the Emulex firmware (rev 'M' (changed to 'R' later, see below)) and try to autoconfigure the drives. The two 1GB drives show up like they should, the 9GB drive shows up as a 500MB drive. Weird. Second attempt: Replace the firmware in the Emulex with version 'R'. Attempt to reconfigure, same problem as #1. Third attempt: Attempt to manually specify the geometry and notice that the Seagate is reporting it has 4925 cylinders but the prompt says the number has to be between 20 and 4095. I enter a number smaller than 4095 and say 'OK'. Now the drive shows up as having 14x10E6 blocks! Ok so now we're getting somewhere but I forgot to configure the other two. Fourth Attempt: Recompute "Fake" heads/sectors numbers so that by using 4094 cylinders I get close to the drives 17,845,431 blocks. Configure the two 1GB drives with all the defaults. Seagate drive shows up as a 1/2 G drive again. On a whim I subtract the number of blocks shown from what it should be, the result is in the 16x10E6 range, aha! I say. Fifth Attempt: Recompute cylinder/sector/head numbers so that the total will be less than 2^24-1 blocks. This works and I end up with a controller that thinks the drive is about 8GB in size (I could live with this for now...). So we go all the way up to VMS. In VMS I type 'INIT DUA0: TEST' and it fails with "%INIT-F-CLUSTER unsuitable cluster factor", I drill down through the help files but there doesn't seem to be a comment on this. It talks about VAX clusters and CLUSTER_SIZE which I tried setting to higher numbers (like 10 or 16). But nothing has worked so far. My questions then are: 1) Is there a way to get the Emulex controller to recognize more that 2^24 blocks on a SCSI drive? 2) Does VMS have a volume size limit in 5.4-1 that I need to know about? 3) If I "split" the volume on the Emulex into two logical drives, can the sum of the logical drive sizes be greater than 8GB? Curious minds want to know! --Chuck (Who is enjoying VMS for the time being ... ;-))

[ClassicCMP] Macintosh Portable questions.

by netsurfer_x1＠hotmail.com

Here are a few questions I have about the Macintosh Portable How much would a 3Mb (or larger) memory expander card cost? How much would a car power adapter cost? Were there ever any cards released that used the ROM slot? Were there ever any cards released that used the PDS slot? Where can I find a detailed pin-out diagram of the Portable's video out socket & a PC's VGA video socket? (The info in the manual is too vague, I require more info so I can at least try to rig-up a cable that can use a regular VGA monitor. That is all assuming that this is even possible in the first place) I know that Dynamic Engineering & Ebay have some of the things that I am looking for, but I am not paying *that* much for some of that stuff, they must think I'm an idiot or something. Also I really don't trust Ebay that much. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

[ClassicCMP] PDP8/S, then GRI99, and later a British machine??

by kevinm＠xpuppy.freeserve.co.uk

Many years ago I worked on a minicomputer range manufactured in the UK. The series was the Molecular 18 sold by BCL Ltd. Having an interest in this machine, and in PDP8 machines, I have been looking for links between the two. (The two machines have quite a few similarities) In an interview, Saul Dinman (who designed the PDP8/S) talks about a later design called the GRI-909. Saul had left DEC at this stage. The company that manufactured the early Molecular 18 machines in the UK was Allied Business Computers, who also produced a machine called the GRI-99. This all may be coincidence and fanciful, but does any one have any information of the GRI range of machines? Kevin Murrell UK

Info needed: Eagle AVL S-100 computer

by Innfogra＠aol.com

Joe; I would ignore the AVL. Does anyone know if Eagle made a S100 computer? My bet is the computer is a generic S100 used to run multiple serial ports. However they could be custom controllers. AVL makes slide projector controllers for large slide shows. This sounds like a very early controller. What are the outputs on the AV cards? Could they conceivably drive Kodak Ektamatic or Carousel slide projectors? Slide projectors use 2, 5 or 7 wire/pin connectors. Some AVLs will control up to 12 slide projectors, usually in multiple of 3s (i.e., 3, 6, 9 or 12 projectors). Two of the wires control the power up and down on the light bulbs. If they did this directly there would have to be some serious power dissipation. AVL was an early adopter of computers. If I remember right Eagle made S100 computers before their crossover clones. This is my guess. Paxton

[ClassicCMP] DIGEST USERS/WANNABES PLEASE READ

by west＠tseinc.com

The digests appear to be working, but likely need some "tuning". It appears the digests are being sent only when a certain number of messages have stacked up. I would like to change it so that the digest is sent out at a certain time each day, once a day, regardless of the number of messages waiting in the digest. Does anyone have any ideas regarding how it should be timed? Also, quite a few people have emailed me asking what happened to the digests. Apparently the old software handled the digests as part of the main list. With majordomo, digests are actually a totally separate list. If you want digests instead of regular traffic, unsubscribe to the classiccmp list and then subscribe to classiccmp-digest which is the name of the digest list. Send to majordomo(a)classiccmp.org with a key of 'unsubscribe classiccmp' Then send another message to majordomo(a)classiccmp.org with a key of 'subscribe classiccmp-digest' Of course, there's no reason you can't subscribe to both :) Pleast let me know if there's any problems.

HTML in Email

> method Allison is using now. <ducking and running> Well... the telnet link makes me think the SR on a pretty 11/70 as faster way to do it. The local at home stuff is rather odd but actually very efficient as it's edit/compose/reply is all done off line then you deliver (also fetches then). It has many things going for it, one it leaves nothing on the ISP, the connect time is minimal, all headers are visible, being slightly brain dead all worms/viri/trojans _can_ be sent through it safely and files TEXT or UUE greater than 50k are saved to disk and the first 1024 chars displayed. the interface is windows/3.1 so it isn't that bad. <> Sheesh. Plain text really sucks. Y'all prefer that someone type _like thi <> to indicate a piece of underlined text? or my habit *bolding* with <> asterisks? This message "encoded" with HTML is roughly 5% larger than it <> in plain text. Wow, now that's a waste of resources. < < I responded in kind (and also in Postscript, morse code, and uuencoded <DVI). ;) You forgot runoff and latex. Yes, html isn't that much larger but, then so is runoff(same thing really). I can read text from the Epson PX8 laptop... HTML is much to fractured looking for a 80x8 screen. Allison PS: orginal message as I initially see it in the view pane. the first 36 lines are just the header so those that never see it may have a clue. ----------------------------------------------------------------------------

PDP-11 sighting - "Sliders" pilot

by ethan_dicks＠yahoo.com

Hi, all, I happened to be watching the Sci Fi Channel tonight and caught the re- broadcast of the first "Sliders" episode. Quinn has a PDP-11 in his basement in San Francisco. It's blurry most of the time, but when he opens a worm hole for Wade and Prof. Arturo, the distortion effect brings the rack into visible clarity - it appears to be an RX01 or RX02 at the top of the rack, over a BA-11N box, CPU unknown. I'm not sure, but underneath the BA-11N, the narrow black vertical panels appear similar to the filler plates on a MINC-11 system, but that part of the rack wasn't shown as clearly. -ethan ===== Infinet has been sold.

WTB: Multibus Cisco Ethernet cards

by ethan_dicks＠yahoo.com

If they aren't classic, they soon will be. I've got this ancient Cisco AGS+ router (68040-based) with Multibus and some kind of Cisco-proprietary slots inside. I have a quad V.35 card (useless to me because of the 26-pin high- density D-shell connectors and no cables). What I need is at least a dual Ethernet card. Whenever I ask my friends in networking, they always tell me the same story, "Oh, yeah. We used to have some of those, but we threw all that stuff out X months ago." So if all these folks have been throwing this sort of stuff out, I figure that *someone* on this list has seen the occasional item float by. Any and all leads are appreciated. I'm willing to pay in excess of 1.2 * shipping, but the sky is not the limit. Thanks, -ethan ===== Infinet has been sold. The domain is going away in February.

Does anyone have any information on this item, a "Prometrix Omnimap 11" in what looks to be a VT-100 case? It's currently for sale on eBay, item 246642084. What was this used for? What OS or Application does it run? Is software available out there from anyone on this list? Was this equipment made entirely by DEC, or does it have modifications made by a reseller? What is this thing really worth? I know, lots of questions! Any answers? Bill whdawson(a)mlynk.com

What's a WD2793A chip?

by edick＠idcomm.com

Be careful what you assume about this chip. As I wrote before, the external lowpass filter is different for different data rates, so if you want to use both 5-1/4" and 8" drives, (and the 3-1/2" ones that look like 8") then you need two lowpass filters. These can be hooked up very simply today as there are analog multiplexors with on the order of 1 ohm of on-resistance, though back then it was necessary to use relatively costly low-on-resistance D-mos switches. I very much prefer the digital approach, which, then, was the only real alternative.
