EISA - was VLB SCSI?

by technos＠nerdland.org

I did read what he said. Sometimes in the early Compaq 486's (and also late 486 Olivetti/NCR/AT&T) you get the error. Used to have a slew of the monsters at work we got cheap to replace dying IBM's. We replaced them with.. Wait for it.. I'll give you a hint, we were bought by AT&T.. NCR 3230's.. Ugh. At least at EOL we could re-chip them, crank the clocks and toss regulators in for employees that wanted one. Nothing like seeing the message "486DX4 running at OVER 100mhz" and chuckling. But you are right, it could be that too. Reset to defaults and reconfig can't hurt. Just I've seen far more (FAR MORE!) with a weak battery.

hard-sector 5 1/4 disk

by mhstein＠usa.net

Hmmm... you don't use Windows much, do you... ------------------Original Message---------------- Date: Wed, 31 Oct 2001 15:29:50 -0700 From: "Richard Erlacher" <edick(a)idcomm.com> Subject: Re: hard-sector 5 1/4 disk The way I seem to remember it is that, back then, we were amazed when things worked, rather than being irked when they didn't. Apple's attitude was clearl, though, and that was that if your data really mattered, you'd certainly use a computer and not an Apple. The Apple wasn't designed from the ground up as a computing machine, but rather as a video toy (not in the disparaging sense) on the order of the several other video games of the time, which, coincidentally could also do some computing. Apple's approach was that if people were willing to buy an Apple and then use it for useful work, they'd try to charge as much as they possibly could, since the overall cost ostensibly would be low initially, and then they'd make their money on the disk drives, (where they had some real margin) and other add-ons that it took to convert the Apple into a computer capable of doing useful work. What makes all this crystal clear is that if I fire up an Apple today, it still does all the stupid disk-subsystem-related crap it did back then, only, by now, nobody would even think of putting up with that. Back then, it was about par for the course, but it wouldn't last a week in today's environment.

classiccmp-digest V1 #761

by ajp166＠bellatlantic.net

Those parts were never cheap! You can also use 74289s for the '189s. The '382s are an improved version of the '182. A note, if you can tolerate a slower ALU you can omit the '382s and just use ripple carry. A sub for 74189s is some of the byte wide cache rams from an old 386/486 PC as the faster ones were faster than the TTL 74189! You dont have to use the full space of the cache ram though having it would make afor an interesting register array.

DEC 9642 enclosure?

by mrbill＠mrbill.net

Anybody know what a DEC H9642 enclosure looks like or how big? The NetBSD hardware reference says its two BA23s... but I need to know if I can fit it into the back of a Kia Sportage. Pictures, anyone? Given that, anybody want one (its a MicroVAX II) in the Austin area? Free, you just have to come pick it up. I'm being given this as a "gotta take this too" in addition to a PDP 11/53... and I dont have room for it in the garage, nor do I have time to mess with it right now...

Heh... depends on the mainframe. The CDC-6600, the world's first supercomputer, was for many years rated as having a mine-hour MTBF... turned out that was because a counter was oveflowing after 9 hours of ticking away, and only under one particular operating system (SCOPE). But even under the more-stable KRONOS operating system, the field engineers typically took it down for an hour each morning. Periodically, they would polish the platters on one of the disk drive units (in the early 90s, we used to kid about using Lemon Pledge to cure stiction, but they drives *really* did get polished), while smoking a cigarette. Ok, I'm drifting away from reliability, so I'd better cut & run. -dq

Pictures, anyone? I don't have the manual to hand right now but my recollection is that it is roughly chest high, about as wide and deep as a UK fridge and would be a pain to load into anything other than an estate car (station wagon to you IIRC). In fact, even in an estate you may find that the box is slightly too high to fit. I picked up a BA123 in my car a few years ago and, although it did fit, lifting it in (with help) and out (without help) was harder than I thought it would be. Antonio

Now that you jog the old grey cells, of course you're right; in fact, the manual states "You should make sure that you buy diskettes for SOFT SECTORED FORMAT (in caps!)...

I did think that the high-density drives used at least one index hole, but no, just looked inside the 8050 and no sensors; wrong again (and how many times have I ranted to myself that people who don't know what they're talking about should keep their mouth shut).

Emulex Qbus Disk controller? (Wiring diagram for connectors?)

by CordaAJ＠nswc.navy.mil

Thanks! I believe I have a couple of ESDI drives hanging around from one of my SGI 4D/70 behemoths.... I've done another quick deja search and, while it's confirmed the ESDIness of the controller, There doesn't seem to be any info out there as far as the DIP switch, and pinouts for the connectors. (I also checked a few other sites I know of that have scanned DEC manuals, but no luck... anyone know of a site with a scanned manual for this critter?) If I remember correctly, ESDI has a MFM-like interconnect with separate control and data cables. The control cable daisy-chains across the drives, while the data cables star out from the controller to each drive. Since my controller has 3 connectors, I would guess that it probably supports 2 drives (one connector driving the control cable, and one data connector for each of two drives) What I don't know is the pinouts for the connectors on the controller (since all 3 connectors appear to be identical in size and SCSI-2 form factor) does anyone have a clue as to the connector assignments and wiring pattern? I can possibly hack a couple of SCSI2 cables to make a viable adaptor... -thanks- -al- -acorda(a)1bigred.com > -----Original Message----- > From: Chuck McManis [mailto:cmcmanis@mcmanis.com] > Sent: Wednesday, October 31, 2001 4:00 PM > To: classiccmp(a)classiccmp.org > Subject: Re: Emulex Qbus Disk controller?

Hi, O.K. the good news is that I managed to boot VMS, read all 40 files from the Ultrix 4.1 boot tape without error (and with the right block size :-) and write those files back to a TK70 tape without major problems. I know that the tape is good and the drive is good. (At least good enough.) And still we won't boot. But that means that something is wrong with that Ultrix version 4.1. It doesn't work on the VAX 6400. Fortunately I am in the position of access to sources that would allow me to build an Ultrix 4.2 based loader. However, I'm even convinced that it isn't the loader's fault. The 4.2 sources of the loader show that it always prints an error before halting. And I never see an error. In fact the only way for the loader to exit without a message appears to be its non-returning call to the vmb.exe gizmo. And -- oh bummer -- I don't seem to have source code for that one. The interesting light pattern at the TBK70 board and the console fault light seems not to indicate a read error >from tape, but more likely a futile attempt of some boot stage of getting to talk to the TBK70 and carrying on the next boot stage. Too bad I can't find out when and where this happens. Anyway, quite likely its in the vmb.exe gizmo which is a black box. So, I might need some boot tape of a newer version (one that properly supports the VAX 6400 series) or I have to find an alternative booting strategy. I guess the MOP booting of ultrix might becoming a more feasible option. So, here is a call upon all of you who know something about MOP booting Ultrix. Please give me any info you might have. I have mopd and am on FreeBSD as the boot host. ... ... ... Another alternative is to set up an "InfoServer" VAX station with a CD ROM and an Ultrix CD of a post 4.1 version. Is this something someone has available? May be in the area or something one could set up accessible through the Internet (a 36 kbps modem line, ahem...) Once I have Ultrix up on one machine I can help others to do the same. If not by writing a boot tape by ... ... here is another option how a good soul could help me get going: If you have an Ultrix 4.2 or higher running on an RA disk, I would appreciate a disk image. That I should be able to raw write to another RA90 (or RA82) using VMS and then boot from that disk. Just make sure there is a GENERIC kernel on the disk image. I still don't have a KFMSA, so RF disk images would not help me. Except, perhaps, if someone has Ultrix 4.2 or higher running and some spare disks to tinker with, I might be able to fiddle a generic disk image that could be installed on any disk. BTW: after having fixed my TU81 unit number problem, I still can't boot from TU81. Seems like the VAX 6400 with my EEPROM revision doesn't know how to boot from TU81. If someone (Geoff?) knows he can boot that way, may be I could use an EEPROM update. Would appreciate your EEPROM dump then.

Emulex Qbus Disk controller? (Need help identifying this one)

by cmcmanis＠mcmanis.com

Search on Emulex QD24 and you'll be rewarded with the information that it is an Emulex MSCP ESDI disk controller. Which can be just as useful as a SCSI card since finding a couple of 300MB ESDI drives shouldn't be too hard. I think I've got a 170MB one laying about somewhere. Kirk Davis (kdb(a)ndx.net) mentioned he had some SCSI controllers he was thinking about trading for PDP-11 gear. Also I just missed a lot that had about 10 Dilog SCSI controllers on it at a local scrap/bid place (had I known I would have bid more than the $75 it went for :-() my interest was in the more mundane things like a couple of DSSI ID plugs and an external DSSI disk expansion box. --Chuck At 11:32 AM 10/31/01, you wrote: >I'm trying to bring up NetBSD on a Vax 4000/300, and so I'm >looking for a MSCP SCSI disk controller.

Emulex Qbus Disk controller? (Need help identifying this one)

by CordaAJ＠nswc.navy.mil

I'm trying to bring up NetBSD on a Vax 4000/300, and so I'm looking for a MSCP SCSI disk controller. After going through my stack of Qbus boards (collected from hamfests, etc.) I came across one that looks like it might be a SCSI controller... unfortunately, I haven't been able to confirm it, since a google search turns up very little on it (a bad sign...sigh) The board is labeled: "Emulex Corp QD2410401-02 rev F" It has 3 connectors and a DIP switch on the front plate. The connectors appear to be of the SCSI-2 form factor. Has anyone run across this critter before, or tried it with NetBSD? Come to think of it, Is this even SCSI, or something else entirely? Also, does anyone know where their might be some on-line docs for it, or at least a description of the DIP switch settings... -thanks- -al- -acorda(a)1bigred.com

HP 2000 notes

by sieler＠allegro.com

Hi, Seen on another newsgroup, I thought this might be of interest to HP 2000 collectors ... particularly the note about "dozens of paper tapes" :) ------- Forwarded message follows ------- Date sent: Wed, 31 Oct 2001 11:11:28 -0500 Subject: Re: [HP3000-L] OT: HP2000? From: John Korb <johnkorb(a)LASER.NET> To: HP3000-L(a)RAVEN.UTC.EDU Send reply to: John Korb <johnkorb(a)LASER.NET> The HP 2000 is a very old machine, the last of which rolled off the assembly line in 1978. George Mason University (the State University in Northern Virginia) had (it is long gone) the next-to-last HP 2000 produced. It ran a version of the operating system with date code 1812. The operating system on this system was "HP 2000 ACCESS BASIC". The system GMU had (which was fairly typical of the HP 2000's of the day) consisted of the following hardware: -- one 21MX-E processor with 64K bytes RAM, used as the "System Processor" -- one 21MX-E processor with 64K bytes RAM, used as the "I/O Processor" -- one 7970E nine track 1600 CPI tape drive -- one 7920 disc drive with 50 MB capacity, of which the Access operating system could only address the first approximately 33 MB -- one 2617 line printer -- one 2392A card reader -- one 2640b terminal as the system console The operating system supported 32 users. As the "HP 2000 ACCESS BASIC" name implies, the system supported a single language, BASIC, but it was a good one, and the old BASIC/V on the HP 3000 appears to be an expansion of the HP 2000 ACCESS BASIC. There were interfaces RJE, and many HP 2000's supported users who created/edited batch jobs on the HP 2000 which were then submitted through the RJE interface to an IBM, CDC, Univac, or other mainframe (as GMU did). There was no print spooler or spooler for the card reader, so people wrote their own, in BASIC, some supporting GE Terminets or DECwriters as remote spooled printers. The accounting structure was based upon account names consisting of four characters - a letter followed by a three digit number. The "A000" account was the equivalent of the HP 3000's "PUB.SYS". It was the system library account, and had special privileges. It was here that you placed the "HELLO" program that every user ran when they logged in, whether they knew it or not. Group library accounts on the HP 2000 were those accounts where the three digits in the account name were "000". For example, all users in the accounts D301 through D399 would be allowed special access to programs/files in the D300 account. The Z999 account was used by HP for special purposes. It has been so long now that I don't remember what the unique capabilities of Z999 were. The HP 2000 also had the capability of running other operating systems in stand-alone, single-user mode. One of these was Fortran, but I never used it so I can't comment on it. In my basement I still have dozens of paper tapes of HP 2000 BASIC programs. In 1999 and 2000 I converted some of those to run on the Classic (16 bit) HP 3000 in BASIC/V. The most difficult part of converting HP 2000 BASIC programs to run on the HP 3000 is that the disc files on the HP 2000 were based on 512 byte "blocks", which means that any HP 2000 application "smart" enough to know the algorithm used to calculate how many free bytes there are remaining in a block (there are overhead bytes for each string, etc.) has to be painfully rewritten to run on the HP 3000. That's about all I have time for. I hope that gives you some feel for the HP 2000. There were many of us who loved that little system. As to whether there are any still running, I don't know, but I doubt it. John At 2001-10-31 10:21, David T Darnell wrote: >Dear List, > >I've seen references to the HP2000 a few times on this list.

Apple II accelerator and Micromodem II questions

I have what looks like an accelerator board for an Apple II. Looks like a Saturn Systems Inc. Accelerator II. Has a 65c02c and 64 K of ram on board. Anyone have any info on this? Doc? What the jumper settings are (there is an 8 switch jumper block on it) or any software needed to use it? This system also has a Micromodem II in it but no doc or the interface from the board to the phone plug. Anyone have a spare plug or the pin outs to make one? Thanks. ----- "What is, is what?"

[Fwd: value of scrap]

by dec.parts＠verizon.net

That might not happen with circuit boards though. What's being recovered is Gold, Palladium, Tantalum, maybe some silver, among other materials. And the competition amongst recyclers to be the one to be able to service this ought to keep them willing to pay for the raw materials. But break your equipment down, so you're just turning in the circuit boards. And if you separate the low yield PC grade ones from the high yield commercial grade ones, you still might do all right with them. > > Here in the UK that might change soon.

A twist on blinkenlights

by dpeschel＠eskimo.com

While visiting the San Francisco area for the Computer Museum History Center's awards dinner, I swung by Stanford to see their exhibit of old (largely Stanford custom) computer hardware. Various groups at Stanford had computer systems (mostly PDP-6 and -10 I believe), but the exhibit highlights the Stanford Artificial Intelligence Lab, a.k.a. SAIL. SAIL had a multiprocessor system containing a KA10, a KL10, and a PDP-6, as well as two smaller computers dedicated to video control, two megawords of memory (eight times the address space of the -10), and disk storage, so they obviously had enough blinkenlights for anyone. But one of the programmers added a box (looking more or less like a tiny traffic light) to his office. Green meant "normal operation". Yellow meant "parity error". (Failures tended to happen in clumps, so after finding one error, the software would kill the affected job and then search for all other errors and kill all other affected jobs.) Red meant "The OS has halted an Exec-mode DDT is running". (Think "kernel debugger".) No lights meant "Things are really messed up". Not exactly high bandwidth, but still an elegant metaphor! -- Derek
