Quasijarus 4.3BSD on 1600bpi magtape

by kelly＠catcorner.org

And I'm not even using 2.11 or any type of BSD. Sun, Sco, Windows or Dos based is all I can read and write 9 track tapes with. Used sun (since compress essentially compiled out of the tarball). Used dd with the different bs settings. Don't blame Michael for his stance though. There are only so many things he can support. I hope these work for John Willis, but I'm not making any promises either. Just trying to help out when and where I can. I've got a 9-track drive and a bunch of tapes to recycle. If it doesn't work, John will have to see if someone else can create the tapes he needs. Either way, working or not, he's more than welcome to try. Keep the tapes and pass em around until you get a working copy if what I did doesn't work. For what it's worth, I read and convert different _DATA_ tapes almost daily. Labelled, unlabelled, ascii, ebcdic, variable length, fixed length, etc. I essentially treated these as unlabled data tapes. I did read the tar files back off onto sco and DOS and was able to "untar" them. diff showed the write files and read files to be the same on both platforms. Hope it all works. -----Original Message----- From: Fred N. van Kempen [mailto:Fred.van.Kempen@microwalt.nl] Sent: Friday, January 24, 2003 7:13 PM To: cctalk(a)classiccmp.org Subject: RE: Quasijarus 4.3BSD on 1600bpi magtape > > Yes.

Problem with 9836C floppy drive

by swperk＠earthlink.net

Hello, I just brought home a late serial numbered HP 9836C in mint condition. It looks fine, shows almost no signs of use (and absolutely no signs of abuse), but it seems to have a startup problem. When I power it up, it goes through its POST and in the list of found hardware are the lines: . . . Flexible Disc Flexible Disc Failed . . . After the POST, but before the 9836C looks for an OS to load, it emits a series of high and low pitched beeps (low, low, high, low, high, high, low). After that, it is able to load an OS (HP BASIC) and run fine, with the exception that the left-hand floppy drive is inaccessible. I've taken a known good floppy drive, floppy controller, and even the CPU card from a 9826A (I swapped the PROM on the CPU cards to convince the test CPU that it was a 9836C), but the error is identical in every case. It also makes no difference if there are cards in the card cage or not, if a hard drive is attached to the HP-IB interface or not, or if there are formatted floppy discs in the drives or not. I found a 9836C on eBay, and strangely enough it shows the same problem at startup as mine: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2303481339 What's going on here? What is the meaning of the beep pattern? Is there a fix? Thanks in advance, Stan

Replies go to the original author. ---------- Begin forwarded message ---------- From: Ron Amir <ronamir(a)pob.huji.ac.il> Date: Monday, January 13, 2003, 8:20:39 AM I work with a Newbrain computer model AD to command a stepper (micromanipulator). I have a mechanical problem with the stepper. There is no manufacturer name written on the stepper. The only thing written is "West Germany" with a logo I can't recognize. As Grundy Buisness Systems were the manufacturers of the Newbrain system I looked for their website but did not find much. I found your e-mail address when I searched the net for "newbrain".

Bulk erasing disk packs

by tim.myers＠sunplan.com

I've managed to get a haul of DEC disk packs, the condition on getting them out is that I erase them (no drive hardware available unfortunately). Some kind of bulk eraser required, I feel, but can I make one / get hold of one easily? The haul is this: 21 x DEC RL02K-DC 10 x DEC RL01K-DC 3 x DEC RM03-P - I believe these are new and unused. 30 x HP 13356 - These 'belong' to the HP 1000 systems that are being moved out this weekend.

Yes, for 1600 BPI. This is a new practice I have introduced with 4.3BSD- Quasijarus0a due to the growth of the source size. 4.3-QJ0a /usr/src tarball won't fit on a 2400 ft reel at 1600 BPI without compression. Since the uncompress utility comes standard with the system (in /usr/ucb) and the binaries are not compressed, I felt that it's OK to compress the sources. MS

Greetings to all. I hope no one will take offense to this request. Today in my mail, along with the usual numerous classiccmp posts, were three messages of a very large size. These three messages totalled 275 KB. AFAICT the original post quoted an entire digest, and the replies then quoted the original message in full. Will you please trim your posts? Many list-members pay by the minute for connection time. I myself use legacy micros to handle my mail; multiple large posts cause severe constipation in these boxes . . . TIA, Glen 0/0

A plea to classiccmpers

by Edward.Tillman＠valero.com

The going rates for businesses in our area (south Texas, using Southwestern Bell) is to bill by the minute, with start/stop time and ring-time measured and billed in 6-second increments. If your party answers before the 3rd ring, there's no ring charge. It they answer between the 2nd & 4th ring, there's a 6-second charge. If they answer after the 4th ring, there's a full minute charge. The main portion of the call is billed by the minute, with your final minute being charged in 6-second increments. Southwestern Bell has a near monopoly here, but the competition (after their lure-in, loss-leader specials) is worse, since the also have to pay Southwestern Bell to use the same trunk lines... -sigh- Ed Tillman edward.tillman(a)valero.com <mailto:edward.tillman@valero.com> > -----Original Message----- > From: cctalk-admin@classiccmp.org@PEUSA On Behalf Of chris > <cb(a)mythtech.net> > Sent: Wednesday, January 22, 2003 1:05 PM > To: Classic Computer > Subject: Re: A plea to classiccmpers > > >Pay by the minute for connection time?

Mr Tillmans - CD History Inquiry

by truthanl＠oclc.org

Regarding the History of data CDs... I did some research. OCLC Online Computer Library Center, Inc. was adapting this technology back in 1985-86. Specifically we were interested in multiple player stacks or jukeboxes for collections of database disks. Phillips, Hitachi, and Sony, were the first drives out. @ $900 - $1000 each Phillips had a proprietary interface card for the PC bus that could support two external drives. Hitachi had a card out that supported multiple configurable I/O Bus Addresses and a parallel bus structure that could support up to 4 external drives off a single interface card. (OCLC selected Hitachi) Each manufacturer also had SCSI cards that could support multiple drives. The big thing was the MSCDEX extensions supporting manufacturer dependent device drivers with their "switches" enabling multiple drives. Once the High Sierra Data format was adopted in 1985, and the MSCDEX extensions were widely distributed, CD Drives became more common. Price fell to $550-$600 ( Later MSCDEX distribution was tied to DOS Version / upgrade distribution ) After Windows 3.X software distribution consumed the worlds diskette production capacity, AT class machines began shipping with CD Drives installed.($110 price point) Here is a (google recovered) link that shows a partial reconstructed history of CD data adaptation: http://www.itc.nl/~bakker/info/rs-data/cd-family.html Sincerely Larry Truthan

Any Cromemco USERS?

The hard way (and the fun way)! I wrote my own CBIOS, bootstrap, and a program to format a diskette, cross-compiled on a modern intel box, wrote a program to massage the compiler output into a text stream that the ROM monitor on the 16FDC would like and then used the monitor to run the formatter. Finally, pumped over the bootstrap, CP/M and my CBIOS and used the sector write facility of the 16FDC ROM to write the whole thing to a diskette a sector at a time. It was very gratifying when the sucker booted up the first time. MS: !!!!!! Very gratifying indeed, I'll bet!!! Wow - that's REALLY doing it the hard way, but maybe it was the only way...! How long did that take? ----------------------------------------- > TM100 drive(s) I assume? Actually, a pair of SA-851s. MS: Ah yes, you did say Imsai chassis, not Cromemco... ------------------------------------------ Something about the 16FDC doesn't play nice with the IMSAI front panel. You can't deposit or examine memory with it on the bus. Even with the schematics, I don't see what the problem is. Do you know a solution by any chance? MS: Afraid not, the Cromemcos I worked with were all essentially stock. Someone else asked me about that a while back; apparently there is a document somewhere talking about using a 16FDC with a front panel. I assume you have the complete manual, esp. PP 64-65, and have set the switches to map out the RDOS ROM? I wouldn't think the interrupt chain or the serial port have anything to do with it, but if your front panel uses I/O ports, I don't think they can easily be disabled on the FDC. Sorry, wish I could help. mike

What's better than canned air?

by cb＠mythtech.net

>Discuss, please. What do *you* use instead of consumer canned air? I bought a small air storage tank at Sears. Its a 12 gallon tank or something like that. I think it was about $40. At first I filled my tank at my fire house off our breathing air compressor, but that got to be a pain, so I bought a small air compressor (also at Sears, also about $40) The tank is good to about 200 PSI, and comes with a regulator assembly and hose. The compressor is good to 250 PSI so it fills it nicely. I added a coiled hose and blow gun attachment, and the system works quite well. The compressor is a tad loud, so sometimes I walk away and close my office door when it is filling (the tank does NOT have a blow off valve, so I can't walk away for too long or I risk overfilling, so mostly I just go deaf when it fills). The only things I don't like are it doesn't last very long. So I find I have to refill more often than I would like. Part of the rapid loss of air is because one of my connections isn't air tight, so if I leave the tank turned on, it slowly bleeds itself (it will go empty over night), but in general, a 12 gallon tank just doesn't last long (way longer than canned air however). Eventually I will replace it with a regular tank/compressor unit, but I'm not in any rush. Also, make sure you use some kind of a regulator so you can adjust pressure as needed. The first time I used mine, I had the pressure up to about 80 PSI and I went to blow the dust out of a floppy drive... I watched the drive head rip clean off and shoot out the other side and across the room. But the drive was real clean! I generally keep mine at about 15 to 20 PSI for most work, going up to about 40 if I am going after really encrusted dirt and dust on things that are sturdy (like a power supply fan). And the other major downside to all this... that dust has to go somewhere... so my work bench now has to get regular scrubbing to remove the crap that has gone airborne and resettled (and I'm afraid of what all winds up in my lungs). Because of this, I have tried to move to a vaccum for much of the initial dirt pickup, and switch to the air for the final details. -chris <http://www.mythtech.net>

Do you know a solution by >any chance? Assuming that you have verified that the front panel works correctly by removing the 16FDC (and only the 16FDC), then the first thing that I would check is to see if the 16FDC is grounding pin 20 (UNPROT) of the s-100 bus. If it is, a quick glance at the Imsai panel schematic will show that all of the flip-flops and monostable multivibrators associated with the Examine and Deposit functions will be disabled. The 'J' input of the flip-flops need to be high, and the 'CLR' pin on the mono-multis need to be high in order for the these specific panel functions to work. Best regards, Scott

Dear Santa, I would like a VAX

by mtapley＠swri.edu

Ade et al, Gotta cast another vote for the 4000 VLC. If you have room for a laptop and an external CD, you probably have room for this VAX. And if you use it to learn VMS, you can (when you can get an 8800, or whatever) charge on ahead to a very asymmetric VAXCluster. Or use it to NetBoot the 8800, etc. I know a guy in Houston, TX who at last count had a "stack" of those with 24M (max) RAM and hard drives with OVMS installed, and for which he's trying to find good homes. I have not mentioned to him the possibility of transatlantic shipping, but let me know if you are interested. And, if you have a lot more money available: (just came up on comp.sys.dec.micro) http://www.aub.nl/vaxsales/ a 3100-85 for 600 (money units not specified) a 3100-80 for 500 both for 1000.

Ressurecting Mac Plus

>Go to Apple's website and dig down in the downloads section - they've got >(or did have last year) all versions of MacOS from v1 up to 7.5.

If they haven't got older versions any more I've got 'em all here :) Last I checked, they removed all except for System 6.0.8 and System 7.5.3. The do have updaters for most of the systems, but they are just updates that need the original system to run. Once upon a time their FTP site did have a number of the pre System 7 versions (not all, but a handful of assorted versions). But I don't think they have ever had full installs of anything but System 7.5.3 in the 7.x and up range (and 7.5.3 should REALLY be updated to 7.5.5 as soon as it is installed... .3 has a ton of bugs in it that are fixed in .5). System 7 is when they went to a paid OS model, so they didn't give the stuff away. 6 and under their policy was you should go to your local Apple dealer with blank disks and they will give you the latest OS version (at least that is what they told me when I asked once how to get an update to 6.x) -chris <http://www.mythtech.net>

As for relocation, that's why you use both P% (program counter) and O% (where the code will be assembled). -- Pete Peter Turnbull Network Manager University of York

Heathkit H-11A (LSI-11) on eBay

by classiccmp＠crash.com

Be interesting to see what happens with this: Heathkit H-11A (DEC LSI-11) with no peripherals but lots of manuals and some software on paper tape and 8" floppy. Hey, the Buy It Now price is a very reasonable US$6,900! ;^) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2302242389&category=4193 Do I need to point out that if I had it, I wouldn't sell it? No connection to the seller, et cetera... --Steve.

What's better than canned air?

I was wondering about excess pressure the other day. I thought about a pressure switch to shut off the motor, but they seem to be quite expensive. Or am I just looking in the wrong places?

Bulk erasing disk packs

by GOOI＠oce.nl

!! RED ALERT !! If you do not have the drive hardware (and computer), you *cannot* erase the disk packs without rendering them worthless! Bulk erase will destroy the data *AND* the servo tracks! If you do bulk erase the disk packs, you can safely throw them away because most of us (all?) do not have the equipment to rewrite the servo track information. BTW. I would like an other RM03 disk pack. I have got only a few of those. I hope to spin up my RM03 in a few months; spare fuses are standing by ... - Henk. > -----Original Message----- > From: Tim Myers [mailto:tim.myers@sunplan.com] > Sent: donderdag 23 januari 2003 12:17 > To: cctalk(a)classiccmp.org > Subject: Bulk erasing disk packs > > > I've managed to get a haul of DEC disk packs, the condition on getting > them out is that I erase them (no drive hardware available > unfortunately).

BBC Micro - assemblers - info needed

by philpem＠dsl.pipex.com

Hi all, I've just downloaded three assemblers from the ROM archive at http://bbc.nvg.org . Catch is, none of them include manuals. I've got copies of: VASM65 v2.0E by Vida Rebus ASM 1.10 by SYSTEM (claims to be the "ASM 6502 Macro assembler V1.10", "Copyright (C) 1984 SYSTEM"). Contains text strings like "Press play", so may be a tape->ROM conversion. ROMAS 3.02 by TBK Associates (full copyright string = "ROMAS 3.02 (C)1985 TBK Associates - S.C." Has anyone here got any documentation for these assemblers? I'd like to get at least one of them to assemble *something*. Perhaps a "Hello World" program? Also, Vasm outputs Intel Hex files from what I can gather - does anyone here have an Intel Hex -> Binary converter for the BBC Micro? Finally, does anyone know how some discs were formatted so they were compatible with 40-track and 80-track disc drives? Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

VAX VMS Question

by crl＠rti.org

Does anyone have a VAX running VMS connected via ethernet to a Cisco 2950 series switch? I have had the VAX connected to a 2900XL series switch for a year with no problem, but in doing upgrades, moving it to the 2950 has caused major character delays, and other problems between the VAX and clients connecting to it. Everything else connected to the switch is working fine. Thanks Carl Lindahl ITS NOC ============== RTI International Ragland Building P.O.

OT (plug) reply: RE: A plea to classiccmpers

by Edward.Tillman＠valero.com

If you want the flexibility of a "hotmail" ((I do, and I have it), but don't want all the animated ads, get a bundle pack like Norton Internet Security. I don't work for 'em, and I've only recently started using the package, but it has a WONDERFUL ad-ware blocker that leaves your viewed web page intact, while simply screening the ad location (turning it black or transparent). I paid $29.95 for my copy, including a 1-year subscription to NAV's virus updates, on the website: NextAisle. Also, there's a couple of freebie packages available on C|Net's Download.com: "Adware," whick you can use to clean your system and registry of cached ad files, and "Pop-up Stopper," which does exactly what it says it does. Both occationally leave you with WIndows Message Service error messages (Of course! Your Adware thinks its broken if it can't cover your screen with its ad!), but these are background, and much easier to dump than the ads themselves. Cheers!

A way to erase OTP components?

by Arno_1983＠gmx.de

Hello everybody, this is something I've been wondering about for some time now. Perhaps here is the place to ask, since it's about one of the "inner secrets of silicon": Tony Duell wrote: > The 8751 is the EPROM version of the 8051 microcontroller. It's otherwise > identical to it. > > If it's in a ceramic package with a quartz window, then you can erase it > like any other EPROM and reprogram it. If it's in the plastic package, > then it's the OTP version. If in fact the same die was used in both components, then it's only the plastic (which is impenetrable to the commonly-used ultra-violet light) that prevents the OTP variant from being erased and reprogrammed. However, there are kinds of radiation similar to light which *will* penetrate the plastic housing...you see where this goes? Will the memory be erased when you, say, X-ray the OTP component, will it stay unaffected, or is the thing just going to die?

cctalk digest, Vol 1 #405 - 38 msgs

Apple distributed the OS free to all up to 7.5x. Probably 7.55 is the highest you should go on a Plus anyway with its limited RAM capabilities, and if you don't really need OS 7.xx stick with 6.08 which is more spry on a machine as old and slow as a Plus. If anyone needs any of the older OS versions I'll be glad to provide you with disk images on CD if downloading is too much bother. Drop me a line. ..SML
