list changes & RFC on archives & rack chassis

by jwest＠classiccmp.org

1) Ok, here are the two things I was considering doing to change the mailing list settings.... A) Reject posts to the list which contain any kind of HTML content. I think this would be fairly unobtrusive - most people don't want HTML posts here anyways. And - I would bet that most all SPAM contains some form of HTML, so this might not get rid of all SPAM forever, but I think it would make the very few that come here dwindle to even less. Comments? B) I also like the 'self-policing' idea of making posts to the list from non-subscribers get a subject tag of [OL] or something like that. This one I am not sure how to do off the top of my head, but would think it pretty straightforward. Comments? 2) WRT the archives at www.classiccmp.org THAT is a project I have fallen far behind in. When I moved the list from the old ISP to the new ISP (me in both cases, long story)... something broke in getting emails from the list to the archive mechanism. I noticed this maybe a month ago, and when I started digging into it I realized it was time for a change - the archives there are not searchable and that just isn't acceptable. So - I have been looking for software to HTML'ize the mailing list that allows searching as well. I really need suggestions here as my initial searches came up less than satisfactory. The archives are currently using hypermail. My criteria is something that is FreeBSD and Sendmail friendly, and allows searching the archives OR viewing them by thread. I don't mind if the emails need to get stored in a database, but if they do, mysql must be the database used (picky aren't I). The only package I found had statements all over it to the effect that "this package will no longer be supported by the author". I did notice the list archives for netsaint that are stored at sourceforge look REALLY nice, and do allow searching, but didn't see a good way to follow threads. I would greatly appreciate it if anyone can point me to mail list archives that work well (for the user) and look nice (or to software for unix that does the same). Please send these suggestions to me off-list at jwest(a)classiccmp.org 3) This isn't really important - just random "what if" thinking out loud - I was considering moving the mailing list and mail list archives off to a separate machine that does nothing but classiccmp. This is being considered for logistics reasons, not for horsepower/load reasons. I have all the spare components (cpu, memory, drives, etc) but no spare rackmount chassis. I can just order a rackmount chassis under my company which I'm perfectly willing to do, but was wondering if anyone had a rackmount chassis just laying around that they didn't need and would donate to the cause. The key criteria - EIA units (space!). I would strongly prefer a 1U (1 EIA unit, or 1.75 inches) tall unit. We charge on rackspace by the inch, so I want the machine to take as little space as possible so I can obviously sell the rackspace to other paying customers. I would consider a 2U (2.5 inches) tall unit (which I already have spare) as a fall-back plan, but definitely nothing taller than that. Anyone have a spare laying around? If so, please contact me OFF LIST at jwest(a)classiccmp.org Regards, Jay West

Apple's A/UX

by mythtech＠mac.com

Does anyone know where there are some archives of Apple's A/UX OS and some of its software (like AppleShare Server Pro, and Retrospect 2.0Ci). I just acquired an Apple Workgroup Server 95 (which is actually 9 years old, so its ALMOST on topic), and since it originally was designed to use A/UX, I figured it would be a good system to play with it on. I'm just not sure where to get a copy, so I figured I would start by asking here, since I know A/UX has been brought up before (heck, maybe I will get lucky, and one of you has the original software that came with the WGS 95, and would be willing to send me a copy). TIA -chris <http://www.mythtech.net>

Basic GIGI usage

by tony.eros＠machm.org

I set up a DEC GIGI yesterday, but I'm not sure I did it right. I connected the RGB connectors to the monitor and connected the "MONO" connector to the "Video In" port on the monitor. When I turn everything on, the GIGI's "Local", "Basic" and "L1" lamps are on and the screen paints from a solid light blue to a solid brick red. Then the screen clears, leaving a block cursor flashing at the top left corner of the screen and the "Online" lamp lit on the GIGI. But I get no response on the keyboard. Are there any GIGI owners out there with a tip as to what I'm doing wrong? Does anyone have any scanned GIGI docs? Thanks! -- Tony

Recent Road Trip pics of stuff avalable PDX

by Innfogra＠aol.com

I was back in Portland for a few hours and visited a friend who is a secondary market dealer. He wanted to know what to do with a Sun 3/280 that I had mentioned to the list earlier and an Alpha 2100 Server he had gotten in. He also had found a couple of rare HP calculators that I had him searching for. Included are the Sun and Alpha, an Alpha 503e Personal Workstation, a HP9100B, a HP46 Desktop, The DEC InfoServer 150 I mentioned earlier and a sneak look at one of the "saved" piles The Alpha Server 2100 I am sure is working but the drives have been pulled, no sleds either. Came from the Government. I think the Alpha 503e PW is complete but I only took a picture of it as an after thought. The DEC InfoServer 150 looks complete and operational. I have the equipment to test there but not the time. I posted the pictures here: http://hometown.aol.com/innfogra/ The Alpha 503e he is planning on selling on eBay. He also wants top dollar for the HP Calculators. However I have got him to take offers from the list first. He has the ability to ship heavy items. He also does a good job shipping airport to airport on some heavy systems. I prefer to be contacted at whoagiii(a)aol.com. Things are getting busy and there are times I can't read the list for quite a while. Paxton Astoria, Oregon USA

Symbolics 3620 screen issues

by tony.eros＠machm.org

I've seeing some screen jitters on the screen of my Symbolics 3620. The characters are sort of doubled up and horizontally offset, as if you had two copies of the same text on a pair of overhead slides, lined them up one over the other and then moved the top one about a half-character to the right. Take the whole thing, make it kind of blurry and you have the effect I see. Is this a standard sort of monitor problem that is easily fixed by tweaking some internal pot (I hope!) or is it likely some bigger problem? Does anyone have any maintenance documentation on this beast or a spare monitor they don't need? Thanks! -- Tony

by Innfogra＠aol.com

Pardon my bad taste in replying to my own message, and the spelling error on the previous subject line. I am posting this on the list because of the broad interest and the fact that I haven't compiled a list of all interested. I will do that soon. I did not get to look at it. My meeting schedule got changed around and was not able to make connections. I did talk with people on the phone so they know there is interest. I spoke with the operator and he said that it is just "idle" at the moment. I have scheduled another appointment for April 1st or 2nd when I will be next down there. It sounds like nothing is happening immediately. Expect pictures like the ones I have posted of my recent Road trip. Paxton Astoria, OR

You have two small round connectors on the back of the drive. Those are the power sequence in and out. You usually hooked all (or groups) of RA81 together with the power sequence cables, and the drives started in sequence. About 10 seconds between each drive. The first drive have a special plug in the in-socket.

Tek 2230 @ 2232

by mdg＠idirect.com

Hi; Question to you Tek gurus; is the 2230 a true digital scope meaning that what you see is a digitized signal or is it an analog scope that has a digital storage function that you turn ON whenever you need to capture something ?. Is the 2232 the same in that respect ? . I remember using one of them years ago at work - I could see a nice trace of 67 MHz (analog) but I could also use a digital storage function to capture a 20 kHz event. Now I need one for myself; as for the digital scopes I've found that the ones I'd accept are those with 2 Gs/sec to be able to see a series of not very repeatable periods at 80 MHz but they are a bit too expensive... .So I need a 100 MHz analog with digital storage capability at lower freq. Please respond to my E-mail adress: mdg(a)idirect.com Thanks, Art

FS/Trade: StorageTek 2920 9track

by pat＠cart-server.purdueriots.com

I'm looking to get rid of my StorageTek 2920 9track tape drive, if anyone is interested. It *might* need a new head, but probably just needs a better I/O card than what I had. PERTEC interface, rack-mountable (actually needs to be racked for it to sit up correctly), about 150lbs, 120VAC in. It worked for a few tapes I tried - the problem might actually be in the tapes I was attempting to use with it. Would prefer local pickup, but could ship (assuming I can find somewhere that'll take something this heavy) if paid enough to do it. I'm not really looking for much money, just 'enuough' for a couple meals or so. Best offer within 24hrs gets it (or a flip of the coin if I get multiple offers). -- Pat West Lafaytte, IN.

IBM 3480 parts

by pat＠purdueriots.com

Well, I can't find any buyers for my IBM 3480 units, so I'm starting to disassemble one of them so I can re-gain some free space and probably sell off the large chunks of steel. I was wondering - does anyone (Sridhar?) have any technical docs for the 3480, like a service manual or something that would tell me the pinouts of things like the display? Thanks -- Pat

Brain rot kept me from remembering how I handled this... I didn't... well, I have a hardware debugger called DryIce-51 or something like that. You pull your 8051, plug this in, it has its own 8051, and IIRC it has an assembler built-in. Handy for debugging interrupt routines, althought it's not a true ICE, so you can't trace through machine states. Then again, more brain rot... I had *some* kind of monitor, because for the DS5000, I found it handier to use it than to pull the chip and stick in the DryIce. Found the SIMTEL 8051 stuff, at least what I downloaded. Wasn't much. But I have a WIC-80 tape labeled to indicate some more 8051 stuff is on it. The 486 with the Jumbo-250 seems to be dying... -dq

You could just re-install to get DECwindows. Without DECwindows you cannot do full-screen editing on the monitor - it's just a dumb glass tty.

IBM 3480 stuff

by pat＠cart-server.purdueriots.com

Well, as I've not found anyone willing to come and get a 3480 tape drive unit from me, I've taken one apart and am planning on selling the 'useful' bits from it. I still have two drive units completely un-touched, so if you're interested in them, drop me a line. I'm not looking to get much money, just enough to cover what I paid for it. So far, I have available: 2x 3480 Tape drives.. the actual 'drive' taken out of the unit. 1x 3480 drive unit power supply 1x 3480 drive 'air pump' motor + filter + air tubing.. a 1/3HP, 250VAC motor with an 'air pump' assembly on it, along with the IBM air filter assembly and whatever teflon (?) clear tubing that came out of the drive unit. 1x 3480 tape drive unit 'display' that has the main 'user-controls' for the drive on it. 1x 3480 A22 tape controller 'logic boards unit'.... the set of logic boards, backplane, and cable from the 3480's controller. Bunches of custom IBM chips and weird-ass cables (don't know the real name, look like a 16pin(?) DIP socket stuck on one of those plastic with metal traces ribbon-cables. 2x 3480 B22 tape drive units, complete. If I don't get any responses, I plan to (attempt) to get rid of the drives on eBay, disassemble the power supplies for parts, try and sell the motors to industrial suplus dealers, and save the displays for who-knows-what. Try and contact me ASAP, if there's interest I can hold onto something for a while if need-be. -- Pat West Lafayette, IN, USA

If you don't mind translating a not too-terribly-long program for another processor, then I believe MIKBUG for the 6800 may do ok. My first embedded systems project was a 6800, and I included MIKBUG in the ROM so that I could precisely what you want to do. The 8051 being a more generous chip register-wise, translating it shouldn't be difficult. You can find at least one version here: http://www.swtpc.com/mholley/MP_A/mikbug.txt Looks like a fun weekend project. Regards, -doug q

Hi Everyone, Now that I have switched to my "newer" system with the box that holds TEN 5 1/4" hard drives, I am thinking of some house keeping on the files I maintain. One very large mess is the set of classiccmp posts that I have some interest in. I would like to group them, but have not decided on sub-sets as yet. I am thinking of the following: Classiccmp General Classiccmp List (this post will go here) Classiccmp Technical Classiccmp Spam (including comments on spam) Has anyone else set up their own sub-sets? I guess I could try these out and see how they work, but I though I would ask for suggestions? Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

No, no, I meant a ZX81 doesn't have one built in. Of course we use the Z80A-SIO (and -PIO). Modems were also commercially produced in the mid-eighties which allowed a simple mod so they could also be used as serial ports. > I've not tried it, but I can see no good reason why you couldn't link up > just about any common serial chip/UART to the expansion connector, and > then buffer the outputs of that to/from RS232 levels.

FS: HP 7470A paper plotter...

by DAW＠yalepress3.unipress.yale.edu

I just rescued an HP 7470A plotter from hitting the round file. But realistically, I'll never use it. has an open foil package with the 5 colored pens in it. And a serial looking cable. Free for pickup in New Haven, CT, or pay (via money order or PayPal) for shipping, packing materials, and maybe something for the labor. :) Now, kinda OT, but here goes. Answers probably should be off-list... I have a Sun Ultra1 Creator. It doesn't want to boot to the hooked up Sun monitor, and yes, a type 5c keyboard and optical mouse are connected too. It boots to the serial terminal, and I get a message "Memory Address not Aligned", then the ok prompt. Haven't had a chance to search online yet. This is my fist foray into the world of Sun. Hopefully I can get Solaris 8 on this puppy, then move to NetBSD... --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1.2 - Darwin Kernel Version 5.2: Fri Dec 7 21:39:35 PST 2001 Running since 01/22/2002 without a crash

HELP! RA81 power sequencing jumper, where the heck is that?

by petersv＠psv.nu

On Fri, 22 Mar 2002, Gunther Schadow wrote: > Whatever. Who can tell me where this power sequencing jumper > is so that I can set it to being the first to spin up? The power sequencing jumper is a small round plug with four pins that are placed in a contact near the black data cables. I can't quite picture the RA81 now, but I think one of the connectors is to the left of the data cables and one on to the right of them. They should be labeled "in" and "out". The power sequencing forms a chain through the use of power sequencing cables such that the first drive in the chain (the one with the jumper instead of a cable on "in") starts first, then the next one and so on. The jumper is about 5cm long, 1cm in diamater I think, usually black with a silvery threaded ring that holds it in position. Peter -- Peter Svensson !

VT-320 Hack+Tip for Smokers

LK401 roolz! >The LK250 however is a TOTALLY different animal and uses >different keycoding to be compatable with PCs or VAXmate >(a sorta PC). There are several different cordsets for this one. Perhaps I can make up by offering a pointer to the VAXmate Tech Ref V1 at: http://208.190.133.201/decimages/moremanuals.htm This includes a description of the LK250 in Chapter 8. The LK201 is described in some detail in EK-104AA-TM-001 VCB02 Video Subsystem Technical Manual (see Appendix B for the LK201 and Appendix C for the Mouse) which is available at the same location. It is also described in the PC100 Technical Reference Manual, which I'll send over when I get a round tuit (same goes for the LK201 printset). Antonio

MSCP Initialization

by chd_1＠nktelco.net

I am trying to get a KFQSA to work with 2.11BSD on a pdp-11. It always fails with an error in the SA register during the transition between STEP 3 and STEP 4 of the initialization sequence. The SA register ends up with the value 101513. The error bit is set and I think that the rest is an error code. I can't find a reference to describe these error codes. An RQDX3 and a CQD-223 in the same machine initialize fine. The KFQSA initializes in an MVIII using NetBSD 1.5. I have looked over the initialization code from NetBSD, Ultrix-32, 4.4BSD, Ultrix-11, and 2.11BSD. The values being sent, are all very similar. One difference is that the VAXen OS use polling during the init, and the pdp-11 code uses interrupts. Any suggestions or comments about the MSCP 4 step init and how it works on the KFQSA? A pointer to error code reference would be great too. -chuck

Wright Punch up for auction

by brian＠quarterbyte.com

There's a Wright Punch up for auction at www.govliquidation.com. The Wright Punch is a cool little manual hollerith card keypunch machine. Someone ought to get it! It slipped by me -- auction closes at 8 PM eastern time, that's less than an hour from now. Sealed Bid sale, $35 min. The downside is you have to pick it up in Norfolk, VA next week, and take a big pile of other junk along with it. You'll need a pickup. If you're interested it's event 623, lot 46, item 37. http://www.govliquidation.com/auction/view?auctionId=25154 Brian =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- _| _| _| Brian Knittel / Quarterbyte Systems, Inc. _| _| _| Tel: 1-510-559-7930 Fax: 1-510-525-6889 _| _| _| Email: brian(a)quarterbyte.com _| _| _| http://www.quarterbyte.com

I don't have either the service manual or my ZX81 handy, so I can't check, but as far as I remember, just remove the 4118 and replace with a 6116. There might be a wire link to change (if so, it's obvious) but I don't remember having to do that. It is good practice to fit a socket, though. A few ZX81's had a pair of 2114's instead of the normal 4118, which were in short supply at one time, but the same principle applies (the PCB is the same). -- Pete Peter Turnbull Network Manager University of York

MiniMINC

From: Tony Duell <ard(a)p850ug1.demon.co.uk> >But the MiniMINC I came across looked just like a PDT11/150. >Approximately cubical, with 2 8" drives one on top of the other. I didn't >have a chance to dismantle it, so I have no idea what the internals were >like, but I'd be suprised if there were Qbus slots in it. It's a plain PDT11/150, as a MINC it's useless as there are none of the usual lab IO items that made the larger QBUS ones useful. One exception is if your systems talk via serial IO then it was a pretty useful box. Now the PDT11/130 (same thing with TU58 instead of RX01 similar) could be used the same way... I think not.

HP 3000 gear in Bristol, UK

by coredump＠gifford.co.uk

I've just been shown a load of HP 3000 and HP 1000 gear which is about to be thrown out, located in Bristol (UK). This list is approximately what's available: HP 3000 Series II 7970 B Digital Tape Unit 7970 E Digital Tape Unit Metier 50 Megabyte Data Storage Unit (disk) HP 3000 Series III 97935 top loading disk drive 7970 E Digital Tape Unit HP 1000 E-series computer "Artemis System" 12979 B I/O Extender 7906 Disk Drive 13037 Disk Controller 2648 A Graphics Terminal 2631 B Line Printer unknown modem 2392 Terminal (qty 3) Flexible disk drive for HP desktop calculator (qty 2) Falco Terminal 91148 Floppy Disk Drive Alignment packs for HP 7905/7906 disk drives They want to clear out the storage space quite soon, and if anybody wants any of it, we'll have to arrange something quite quickly. Most of the computers are in 19-inch racks of about 5-foot (1.8metre) height, but some of them are double-width racks. Basically, you'll need a van to move them!

HP-IB <something>

by doc＠mdrconsult.com

I grabbed this yesterday at goodwill. It looks like an HP-IB/floppy-IDE interface, but I can't find any references. HP model appears to be: 09L Rev C 09153-66511 or 2815 or 0TF0C07 or RSWKC3 The card has a bulkhead plate w/ HP-IB connector, address dial switch 0-9, and configuration dial switch 0-9. PCB itself is about 10" by 3" with a 1.5" by 3" cutout. There is a 34-pin male and a 40-pin male header and dip switches: TEST <--> NORM B <--> C 30/40 <--> 10/20 BOTH < 10/30 <--> 20/40 NO FLOPPY <--> FLOPPY What is it? Doc

Nope, It's an LSI-11/02 Qbus machine woith a small cage and rack and RX01(maybe an 02). You need Qbus for the varions analog IO and digitial IO cards. >I am not sure how the miniMINC differes from a PDT11/150. By rights, the >miniMINC should have some kind of 'lab' I/O (ADC, etc), but I have no >details of that. The PDT11/150 has no user bus and the oly IO is serial. It is however the same LSI-11 chip set but no provision for the EIS/FIS. Yes, I know you can piggy back one of the microms to do that but the board only has 4 40 pin sockets that are filled where the LSI-11/03 Qbus board has 5. Allison

After considering this, I think you've hit the nail on the head, Joe, except that the only thing we don't change is the engine! The Z80, ROM and ULA *have* to be present! Our goals seem to be: 1 -- Build an interface for every device under the sun, including the toilet seat. 2 -- Write software to perform every task ever performed by any computer anywhere. The software should be 100% Z80 machine code and should push the ZX81 as hard as possible. 3 -- Do all of the above for US $25 or less. I hope everyone has as much fun with their old computers as I have with mine! Glen 0/0

Destruction of DEC

DEC's destruction began when DEC was palmerized into a ghost of it's former self and sold into slavery to Microsoft. Then much damage to this once great computer company, DEC, was done by Compaq (a wannabe computer company that never made real computers, and destroyed an acquisition, DEC, that did), and, now, this appears to be little more than the nails being hammered into the coffin of what was once Digital Equipment Corporation.

SGI Dials & Buttons and no P/S

by hans＠Huebner.ORG

Hi there, I've recently acquired a set of SGI dials and buttons. These are two units: The dialbox has SGI P/N 9980992 and is manufactured by Danaher Controls with Model # DLS80-1022. The buttonbox has SGI P/N 9980991 and is manufactured by Advanced Input Devices with Model # CMN B018B. I have not received any cabling with the units and also I have no power supply. Using google, I could not find any useful information on how these units are expected to be supplied with power. There are some references to SGI boxes which provide for power supply on some serial ports, but these where pretty unspecific and did not reference these exact models. Does anyone reading this have a set of these and can help me with getting the pinout and the expected voltages for the power supply for these units? Thanks in advance, Hans -- finger hans(a)huebner.org for details

Ok, I'll agree that it can and does, since I am unfortunately forced to use it by corporate edict. :( I will argue that it's not "easy" to turn off. "Easy" would be a button that says "don't ever post a message with HTML." There is no such option. It must be turned off as a default, and then still on a per message basis every time you don't want to respond to somebody who's used HTML with another HTML message. So I will agree completely with you if you will replace "easy" with "cumbersome at best."

I picked up a copy of Central Point Software Copy II Plus ProDOS/DOS Utilities, Version 9 (1989) at my local thrift shop yesterday -- didn't realize it was for Apple at the time. I don't need it, so if anyone wants it, they can have it for $4.00 in the US (what I paid plus shipping); international shipping will be more. It will work on an enhanced IIe, a IIc, or IIGS, all with 128K and 80 column card. Includes 5.25" and 3.5" disks; looks unused. Bob robert_feldman(at)jdedwards(dot)com

Handyman specials

by Robert_Feldman＠jdedwards.com

I have the following junk^H^H^H^H R@RE computers for anyone who wants them. Pick up in Chicago or pay shipping costs. Most are untested and might not work, all are dumpster finds: (in order from largest/heaviest to smallest/lightest) HP Portable Vectra Toshiba 3100e/40 (power light comes on, but does not boot) NEC MultiSpeed EL TI TravelMate 4000M (color LCD, 486 DX4/75, but was found partially disassembled, so most likely does not work) AST PowerExec 3/25SL (no hard drive) Tandon NB386/SX (has loose/cracked hinge, but is the only one with its power brick) Kenitec (no model number; probably XT compatible) I also have an NEC MultiSpin SCSI CR-ROM reader, external. Again, I don't know if any of these work, but if you've ever wanted to tear apart a portable, or play with an LCD screen, they might fit the bill. Bob robert_feldman(at)jdedwards(dot)com

It's my opinion that Compaq will be pissed away by HP just as Compaq pissed away DEC. I never really did *love* Compaq, mainly because they are a PC company. They make good PC's, but I hate PC's.

VAX 6460 being slow, IO bottlenecks and SMP woes ...

by ajp166＠bellatlantic.net

From: Gunther Schadow <gunther(a)aurora.regenstrief.org> >Yes, so, let's suppose that ULTRIX didn't take full advantage >of the hardware, but nothing can get me back to using VMS. That's >for sure. Ultrix was not nearly as well developed as VMS for multiple CPU and cluster configs. Available user performance on a 6k system with decent disks was very high under VMS but under ultrix is was a less appealing system. I'd used an identical pair while at DEC with both ultrix and VMS and the ultrix system was a bit doggy even at lighter user loads (no one liked it). Comparing it to a 486... no contest with a pot load of users. the i486 does not have the system robustness and IO capability. Allison

Plexus minicomputer?

by vcf＠siconic.com

Anyone know about Plexus minicomputers? I am going to pick one up soon. I'm told it's about 3-4 feet high by 2 feet wide by 5-6 feet deep, and heavy. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

While we're on the subject, I do think the [OL] idea is a good one, but I just wanted to add my tuppence worth on the subject... The address I post from isn't always the same as the one I read it from; I tend to choose the address to post from (work or home) as appropriate to the content of the message... If we go with the tagging off-list posts, it would be nice if there was a way of registering additional 'posting addresses' as well as the subscription address. Not essential, of course, but would be handy (would be more essential if we got to the stage of actively blocking off-list posts.) Incidentally, I'm all in favour of the blocking HTML, by the way...

VAX 6460 being slow, IO bottlenecks and SMP woes ...

by gunther＠aurora.regenstrief.org

It is very contemplative to sit in the basement, room filled with big iron and lots of blower and disk noise, and watch the system creep ahead compiling stuff. I remember those old days back in, say, 1994 when I sat there on a i486/33 watching GCC compile (and those *endless* runs of all the fix-include stuff.) What surprizes me is that the feeling on a 1989 vintage 6-processor million-dollar VAX isn't very different! I expected it to be faster with that. So I looked at statistics. Nothing paged out (0.5 GB of RAM), but looks like the system is heavily I/O bound and I/O is quite slow. I even distributed disk load over 3 RA90, though all on the same controller, but at least that's a KDM70, directly on the XMI bus. Still, disk access seems just a bit on the slow side. Why? All terminal I/O went through the Ethernet, which I thought was a DEBNT but is reported to me as a DEBNA. Anyway, that's just the few lines of text that are being logged as make creeps forward with its job. Looked at cpustat (we're on Ultrix 4.5 BTW), where you can see the load on the CPUs. Sorry, no "screenshot" here, but in short it lists 6 CPU's and the load on each. 5 of them tend to be 97% idle and CPU#1 is 75% idle. CPU #1 gets bombarded with all interrupt requests while the others get none of that. Unfortunately I couldn't figure out how one can see process to CPU allocation. I suppose that each process runs in a single thread on one CPU every time it is active. Since the making and the cc-ing is a sequential thing writing temporary files to disk, I suppose that the 5 idle processors have nothing to do while CPU#1 takes all the burden of the compiling task plus all other system interrupts (essentiall all I/O.) So, that's kind of not optimal. I suppose, once I have my first GCC built I should use the -pipe option to avoid temporary files with the hope that the two ends of each pipe would then be allocated to two different CPUs. That should then speed up the process a lot, basically could stream cpp on CPU#1 to cc1 on CPU#2 to as on CPU#3 right through. I hope. That is, if UNIX domain sockets (i.e. pipes) are implemented so as to not require any hardware IO. I *hope* this is simply done by CPU#1 entering kernel with an mbuf and CPU#2 entering kernel shortly thereafter reading that mbuf, so only memory should be involved. It's interesting. At some time soon, may be early this summer, I'll give a VAX party where one of the highlights will be a race between my i486/33 and the 6460 in compiling something, there we can see if it's really just my perception that the 6460 is kind of slow for the price, even measured by past standards. Another thing that made me wonder is that writing to the TU81+ on KLESI-B showed its signs of I/O bottlenecks. When I just did # tar cvb 20 -f /dev/nrmt0h /usr5/gcc-2.7.2 the tape would write block by block in staccato and would not stream. The TU81 is still nice even in block mode, not that endless back and forth of the TK50 or any other cassette media that I have seen operating, it's a fast staccato tatatatatatata, you gotta see this! Only if I used my dd buffering trick with # tar cvb 20 -f - /usr5/gcc-2.7.2 |dd ibs=2048000 of=/dev/nrmt0h obs=10240 would it stream over larger sections. But the slightest disk read activity would cause a little pause to the tape transport. First I thought I should be rearranging my cards on the VAXBI busses, but then I remembered that the disks are on XMI directly. So, a simple RA90 read through KDM70 on XML is just not fast enough in order to keep the VAXBI - KLESIB - TU81+ streaming. Are the RA90 disks so slow? Or may be it is Ultrix' bad way of using the multipe CPUs again, i.e., they still handle all the work through one single CPU#1 while the others are chatting idly? Does NetBSD do a better job with SMP? Would it use one CPU for the disk IO and another CPU for the KLESI-B IO with shared memory buffers in the middle? May be not if I used just one process to both read from disk and write to tape (like tar only), but with the pipe, tar | dd it should do it and that should allow me to use a smaller ibs for dd, AND have real streaming write to the tape. Or is SMP on NetBSD/VAX still a sub-optimal hack? When I attended BSDcon 2002 in San Francisco few weeks ago, it seemed like all the BSDs would go different ways about SMP. I liked what Jason announced about NetBSD, like IO being handled without memory data copies, and the kernel actually shrinking in size. I would hope that all BSD/SMP efforts nowadays seek to allow true load sharing between the CPUs and not shedule IRQs to only one and not hog that one primary I/O CPU with *all* processes that have any I/O to do. And I sure hope that it will be natural for pipelined processes to operate on different CPUs.
