Dying VaxStation 4000 VLC - help? - fixed!

by mtapley＠swri.edu

All, The result: Replacing the electrolytic capacitor on the lower leg of the voltage divider feeding the reset comparator did the trick. The system is now up and running normally (but I've forgotten the password! Hope I wrote it down, else I'll have to re-build the system...). Many thanks to Tony D. (who guessed right the first time), Toth, Peter, Antonio, and anyone else I've forgotten. Sorry it took so long to report - I just this morning got my friend at work to put the new capacitor in place. I still have the presumed leaky capacitor he took out, but have not tested it. Details of the problem are (presumably) in the archives; in brief, the primary symptom is that the system won't come out of reset (the code LED's on the back won't start flashing) on power-up, or falls back into reset peridically while running. Anyone with similar problems, I'll be happy to relate my full story and send pictures if desired. I *love* being on this list! Thanks again to all! - Mark

Help with my PDP 11/73

by chu＠verizon.net

Hi, Thanks. Big success and then a new problem. I took out the top three levels of my cards and reseated them. There's a lot of corrosion on the contacts so it inserts only with difficulty. Anyway it booted up ONCE and I saw lines indicating that RSX11-Mplus was starting up. It went through an initialization script and then I/O to the console terminal died. I have not been able to get any more output from the console. So my next problem is to figure out what happened. Progress is being made. One big good thing, at least my disk has to be working.

vi for the C64

by spectre＠stockholm.ptloma.edu

I've made good on one of my long-standing threats and created a small implementation of the vi editor for the C64. svicc features an extended subset of nex/nvi commands and is designed to integrate well with Commodore BASIC. It supports many basic motion, editing and positioning commands and includes a number of Commodore-specific features, including a built-in disk wedge. Almost all 38K of the BASIC text space is available for documents. The web page also details how to use svicc to build self-displaying documents. Basic documentation is built-in to svicc, and the web page has a complete reference intended for current vi addicts. svicc is freeware. Have fun. Comments appreciated, including its performance with accelerator cartridges and the SuperCPU. http://www.floodgap.com/retrotech/cbm/svicc/ -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- I do not know myself, and God forbid that I should. -- J.

looking to get a VAX 11/750

by pzachary＠sasquatch.com

It seemed to me before I called up someone out on the east coast and bought a VAX-11/750 for $150=/- then spent $250 or so shipping it that I should try the list. I want a VAX 11/750 for old times sake and as a peripheral for my pdp-11s... anyone have one for sale/trade/...? Thought I'd rather a local had the money to buy inflated pdp-8 spares or something than giving it all to a shipping company. I'm located in santa Cruz CA and am willing to pick up within a couple hundred miles. I would really like to get out of this for less than $400 (really $250 seems like a fair price(that's what they sold the one I ran out from under me when the funding ran out and I was on vacation for (rant ends)) but I'll take what I can get) further, I have much of a card set and a power supply or two, so if I get a incomplete one that's O.K. thanks, Pavl_ sorry about the joining in of the rant/flame thing RE:politics, I can usually restrain myself but sometimes when it goes on... and to respond to the digest-delayed list makes it worse I know(I've at least changed the last bit)

Harris 6100 CPUs

by classiccmp＠vintage-computer.com

I've got a line on some "early run" Harris 6100 CPUs (with data sheets) in "unmarked ceramic packages" for $10 per. I'm interested in one or two for some odd reason (I guess I want one or two of everything, when you come right down to it. . . :) but the seller has about 10-12 for sale. Is anyone else interested in these? Are they worth the $10? I'll be happy to be the clearinghouse on these for anyone who is interested (I'll buy them and forward them along for cost.) Erik S.

Wanted L5-30 Outlet Receptical

by truthanl＠oclc.org

Jeffery Please consider your mechanical connections and the duty cycle of this Adaptation. I have an air conditioned cruiser I keep on Lake Erie. It has two L5-30 125 V marine power feeds that come to a power distribution panel. Current ( and voltage) is constantly monitored on analog meters (two per feed, -one Volts - one Amps.) The one feed that runs only the Air Conditioner, averages 9 Amps and the other house circuit, which has a battery charger and refrigerater on it, average 5 AMPs so I thought One 30A Cable could supply the boat. ( got tired of the mess of two cables draped over the bow and decks - spider habitat! ) After a couple seasons, I made a splitter out of 10 Ga stranded copper wire using heavy set screw terminal lugs for the split connectors. I ran one 30 Amp cable 30 feet to the splitter. and then let the 20 inch splitter, split the feeds. I used all top quality 'Hubbell" marine connectors for the terminal receptical(s) & outlet(S) on the single feed cable and the splitter. Just this last season I left Air conditioner running for about two of the hottest weeks in September ( freakish -Indian summer). When I went to cast off the lines for a Fall trip to the Islands, the terminal connections on each end of the single feed cable failed due to heat. Un-twististing the twist lock at the remote receptical end was tough, then the Ground and Hot blades pulled out of the plug end at the dock outlet. I had to switch off the dock breaker and extract the blade components using needle nose pliers. My Point is the 30 Amp feed cable (the oldest component) perhaps had some vibration, or corrosion, compromised mechanical connections. Which over time (2 weeks) created enough heat to compromise ( melt) the quality parts. All my parts were rated at 30 amps, and I knew my usage was less than 19 Amps! ( If I was not in a hurry to take the splitter with me, the parts may have cooled and re-set (solidified) rather than than pulling apart. But it was truly an education in real world failure modes of decently rated parts. If you are adapting down to a 15- 20 amp plug, you will still need to be EVER mindful of the physical condition, and operating temperatures of any mechanical connections you make.

Gridcase 1530

by kandres＠epssecurity.com

Greetings all, I have a Gridcase 1520 286 with plasma display that I bought years ago to work in dark areas with. It has the same problem that was mentioned where the CMOS battery is low/dead, and does not maintain settings. I have mine on a bench currently running an exercise for a graphic driver board fed by serial numbers. I put together a "boot" floppy for it when it first started losing its settings in CMOS. As was previously stated, hitting "F" at boot up will cause the machine to load from floppy. I have done that for a lOOOOng time for lack of time to change the battery. Hitting "H" selected boot from hard drive as I recall, but I have had no problem accessing the hard drive once the floppy boot was accomplished. Of course the correct thing to do is replace the CMOS battery as one writer suggested. If you do not solder, find someone who can. Kev

If this does not work, I would look at the handshaking first. If that works, and you have a logic probe, you could change the A3 jumpers back to their original jumpers and using the logic probe, test for the pulses being received at pin 3 on the 8251 at B5. --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog =========================================

Help with my PDP 11/73

OK!!! The null modem that I just bought must have been bad. I got another one from a different vendor and I can talk to my processor. I am able to get into dialog mode, setup mode, and into ODT. I runs the self test loop correctly. However, when I try to boot either DU0 or MU0 the machine gets hung up. My assumption is that the disk may have been erased before sale and the tape cartridge I got is probably blank. Where can I get a copy of XXDP on a TK50 cartridge? Or is there another way I can determine if my two peripherals are working? TIA, DAve Chu

You need to put a dummy read first. This will cause the drop of alternate characters when working right but this is for debug. Try: CIN IN DATA CIN1 IN STAT OUT FFH ANI IBIT JZ CIN1 IN DATA ANI 7FH JMP CIN If you don't see any change, try some of the other ports, near by for STAT, like 0 , 1 or 2. If that fails, you could be having a problem with the serial lines someplace. You need to check the levels on the serial chip inputs.

"page left blank"

by Innfogra＠aol.com

Not that it matters much, but I think it's due to the way pages are printed and bundled together into sections (graphs?). "Signatures" is the correct term for the bundle of pages and "Imposition" is the way the pages are laid out on the sheet. I spent 10 years as a printer/typesetter. In imposition, if you wanted a page left blank, you just left it blank. I think labeling "page left blank" deals more with the expectations of the user or reader of the book than of the printing process involved. Paxton Astoria, OR

Why did they publish 'blank' pages

Berg Connectors

The main problem is that when using standard 40 pin connectors they are narrower so it is possible to misalign when plugging in the cable. I have put a blob of glue on the ends of the connector to take up some of the slop so I can't plug them in wrong. DEC used a 44 pin connector for the discrete wire which doesn't seem to be common.

"page left blank"

by grg2＠attbi.com

Not that it matters much, but I think it's due to the way pages are printed and bundled together into sections (graphs?). Many printing presses are large enough to print 4 or more pages at a time on one sheet. Then the sheets are cut and folded into sections. This means the number of pages printed and pages per sectio have to be a multiple of 4. So one often ends up with a few blank pages at the end of each section. Nothing that can be done about it without some heavy-duty computer page composition, easier now, but not even remotely possible before 1970 or so.

Converting simh .tap file to real tape

by cmcnabb＠4mcnabb.net

I've a .tap file with an image of the micro 83 maintenance tape. I tried writing the image to a real tape using vtserver, however, vtserver appears to want to put the entire .tap image into one tape file on the real tape. Is there a program out there that will do the correct thing (boot blocks in file 0, data in file 1, etc, etc)?

Apple IIe / Ddial update

by rick＠netadel.com

Some kind soul left a disk II controller card and a 80 col/64k card on the shelf where all the IIe's are at Weirdstuff. I picked up a platinum IIe, plain old second gen ][e, a pair of disk drives, the cards, and a mono monitor for 25.00. I believe that to be more than reasonable. Now.. I popped in the SS cards I got from Sellam (thanks!), and the disk with Ddial, and loaded it up. Bummer for me is the ddial was the first version that does not support the serial card linking .. Has anyone got a later version of Diversi-Dial? I'd even pay cash for it :) Not too much though, my wife is already irked at the Apple "monstrosity" that "seems to have grown by itself"

Emulated Peripherals

by brian＠quarterbyte.com

I was sort of shocked to see snide remarks directed at the guy who posted a (well, blatantly commercial -- but let's pass that by for now) message about his company's legacy emulation products. First, most people who are still using classic/legacy hardware in their business aren't doing it because they think it's fun, or cool -- they're trapped, and a bit foolish. Given the expense, limited support, and general unreliability of the stuff, it's hard enough to justify using even the CPUs for mission critical operations, but absolutely senseless to keep using classic storage devices when they can be using modern, available, interchangeable, reliable replacements. Their goals are different than ours. Our is to play with the stuff for the enjoymment of it, to preserve it, to teach people about it. Most businesses have no -- um, business -- letting these motives dominate their need for security and stability. Second, it's pretty damned presumptuous to assume that these folks have any less appreciation for the old technology than we do. They're keeping this stuff going, keeping it at work, and getting paid a fair price for it. Bully for them. Third, does it make sense to offend the people who are first in line to help find new homes for classic gear when it eventually gets completely decommissioned?

[possibly OT]: 80386 I/O card jumper settings

by philpem＠dsl.pipex.com

Hi all, Well, this is just about covered by the "10-year rule", so here goes: I've been given an old 40MHz 386DX motherboard with a separate I/O card. Ordinarily, this would not be a problem, except the previous owner has disabled the COM (RS232) ports on the card and has lost the jumper settings. Looking at the component side of the board with the mounting bracket to the right, the card has an IDE connector marked "JP1" on the left hand side, a floppy disk connector (JP9) on the top, a Game Port connector (JP10) and an RS232 connector near the bracket. There are four banks of jumpers - one consisting of JP2, JP3 and JP4; another labelled "JP6" (bank of 6 jumpers, three pins); another labelled "JP7" (bank of 6 jumpers, three pins) and finally one labelled JP8, a bank of 8 jumpers with only three jumper caps. The board has a holographic sticker (holographic text is "Polaproof", "Wugo" is printed on the label in blue ink) on the solder side. The controller chip is a Winbond W83757F, complete with a few MC1488/1489 linedrivers, some LS244s and LS245s and an NE556 Dual Timer. Has anyone come across one of these boards before or, better yet, has jumper settings for it? Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Recent Activities (11/34)

by jss＠subatomix.com

This weekend I decided to start the process of building and making work my PDP-11/34 (upgraded to 34a). Most of my CC activity will have to occur on the weekends, because my job is quickly ballooning to nearly fill up each day. Not that I mind; my job is fun. Now before you can get that "I told you so" off your lips, I will have you know that I *still* have more time than when in college for playing with my toys. Weekends are better than nothing. The first thing was to get access to the machine. Ouch, but success. Next, I made an inventory list of all the cards in the machine. I'll paste it at the bottom of this mail. Next, I downloaded and started reading some manuals, including 11/34 UG, BA11-K UG, BA11-K FMPS. There are a lot of pages there, and I want to read them before doing too much more, so I'll print them out and take them to work for some lunchtime entertainment. Another thing I decided was that I needed to mount this thing in a rack before I do too much more with it. Mainly, I need to get to the underside easily. I tried to harvest some rails from the rusty 11/70 carcass in the garage. After some work, I was able to get the BA11-K in the carcass to slide out, but it was too stuck to get off of its rails. I couldn't tilt it up, either, because one of the releases wouldn't budge. I decided to take the entire thing off, rails and all, and remove the rails later. I also decided to get a friend to help, just in case. Unfortunately, my friend is sick this weekend, so I couldn't do much more. I did fire up the compressor and blow air into the machine and into the LA120 I have nearby. I think I'll play with the LA120 a little and see what condition it is in. Next weekend, I hope to get the 11/34 mounted in the H960 rack, read the manuals, and document jumper settings on the various boards.

Wanted: KG11-A Manual

My PDP-11/20 includes a M7251 KG11-A board, which appears to be a CRC helper option for communications software. I've been able to find some diagnostic code listings for it, but no manuals.

What computer is this front panel for?

by n8uhn＠yahoo.com

Wow, thats a tough one. i agree with Sellam, it does look like a four phase panel. but - fps did not use a flat rack panel - they used a bezel and the board bolted to it. i wonder if it is fps and perhaps an iv/60,70 or 80 or an early prototype of one of them. if the seller looked at the pcb for a name - that may end our mystery - fps screened "fps","four phase systems inc" or "motorola information systems" or the pcb. motorola information systems bought out fps and made some boards for the fps systems.

i wonder if it is fps and perhaps an iv/60,70 or 80 I have a IV/70 reference manual, and the front panel is quite different. Four Phase also numbered their bits in big-endian order. I'm still guessing they're for Harris H-series.

IBM Displaywriter etc

by dancohoe＠oxford.net

I ran across a number of Displaywriter cpu's and keyboards on the weekend as well as a bunch of IBM 4972 terminals. I think I may find Series/1 parts in further searching through this interesting site. I didn't know what the floppy drives for the Displaywriters looked like until I checked with Google after coming home. I believe I saw some of them as well. I also picked up some manuals and diagnostic diskettes for the IBM Office System 6. Anybody need them? The actual System 6 is there but has been out in the rain too long to be of much interest unless someone needs something specific (and waterproof) from it. Quite a lot of other stuff as well, which I'll list as, if, and when I get to it. If anyone is interested in any of these things, I'll try to get them put away in safe storage. I'd be willing to hold on to them until Dayton. The owner is very reasonable with his selling prices. regards, Dan Cohoe

NeXTStation Color monitor cable pinout needed

by ian_primus＠yahoo.com

Thanks to your help, I now know what I need - I need the three headed cable with two 13W3 connectors and one DB-19. ( this thing - http://www.obsoletecomputermuseum.org/nextcolor/monitor_cable.jpg ) I have scoured the internet looking for the pinout of this cable, but to no avail. I did find some information about the monochrome slabs, but it doesn't help me very much. There doesn't seem to be much out there about the color NeXTStations at all. Anyway, if anyone has the pinout of that monitor cable, it would be much appreciated. It shouldn't be too hard to add the extra connector to the old Sun monitor cable I already have. All the pins on the Sun cable do go straight through, and there are wires for all of them, I checked with a multimeter. Thanks! Ian Primus ian_primus(a)yahoo.com

In the interests of keeping viable machines still functioning, and given that this is for a non-functional museum display, it might be worth looking into actually making something - painted wood, vacuum-formed plastic, whatever. Just a thought. I'm not a DEC person (don't have the space!) and these switches might be common as muck for all I know. But I'd hate to think parts were being used on a static display that could be used to keep hardware running elsewhere... cheers Jules Everything you'll ever need on one web page >from News and Sport to Email and Music Charts http://uk.my.yahoo.com

vaxstation 3000?

Berg Connectors

by chd_1＠nktelco.net

Is there a replacement for the Berg connectors? I am talking about the 100mil spacing, dual inline connectors that had individually insertable, crimp contacts. The AMP MT connectors look like a replacement. Does anybody have experience with this? I am working on an DEC RX01/RX02 emulator for my pdp-8/e and want to run a cable about 20ft. I was thinking about using 4 runs of cat5 twisted cable and the individually contacts would be quite convenient. -chuck

Getting Started with VAXen (was Re: vaxstation 3000)

by classiccmp＠crash.com

> To the classiccmp DEC-heads: is the 3000 a good starting point > for someone who's curious about VAXen? If not, why not, and > what would be a better place to begin? If you want to get started with VAXen, any flavor of VAXstation 3100 would be a great place to start. A basic VS3100 (aka model 30) would be an adequate, very cheap way to start. They'll do everything you'd need to begin learning about the VAX and VMS, Ultrix, or *BSD. These early models are limited in terms of expansion and speed by current standards, however, and if you have the money or opportunity you might want to look for something faster like a VS3100 m76, or any VS4000. To learn more about the different VAX models, I'd take a look at the NetBSD/VAX page http://www.netbsd.org/Ports/vax and look into the different model descriptions. To get licenses and media for running VMS, go to the DECUS/Encompass OpenVMS Hobbyist Pages at http://www.montagar.com/hobbyist/index.html You'll have to join Encompass, but that's free. And you'll need the serial number from your VAX/Alpha. If you check the archives for this mailing list, or hit Google Groups archives for comp.sys.dec and comp.os.vms, you'll find all kinds of info and links to web sites. Good luck, and have fun! --Steve.

Question on chip date code

by vcf＠siconic.com

I am looking at a chip that is causing me confusing with regards to its actual date code. The chip is labeled thusly: (logo) /718 DM74157N 9322 (logo) looks something like this: /\/ /\/ ...which probably makes it National Semiconductor. My first instinct is to guess that its date code is 9322. However, it does not fit within the context of the rest of the board, which is 1976. They are definitely not original, as the board calls for a 74257 but the 74157 has been put in its place with the addition of a capacitor across +5 and ground. Is it possible that the date code is actually "/718", and what I am seeing as a slash is actually what remains of a '7' that wasn't printed correctly? -- 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 *

Mac Printers (Cambridge, UK)

by julesrichardsonuk＠yahoo.co.uk

OK, I haven't decided what I'm doing yet with the various Apple machines I got the other week, but I know the printers are just getting in the way, so if anyone wants the following just give me a shout: Apple Stylewriter II + manual Apple Colour Stylewriter 2500 - no PSU, needs 13.5V HP Deskwriter 660C + PSU + driver disks (ok this one doesn't hit the ten year mark :) I had the same printer for the PC which failed a while back, and I kept the centronics interface board from it so you're welcome to that too. I may also have the manuals for the PC version still, which might be useful. I've only got the one data cable, currently plugged into the colour stylewriter; I expect it works with all three printers though. I have no idea what of the above works - all the systems that came in the same haul worked fine though so I expect they were just dumped as surplus. Free for collection from Cambridge, UK. cheers Jules Everything you'll ever need on one web page >from News and Sport to Email and Music Charts http://uk.my.yahoo.com

PDP-8 front panel switches needed

by vcf＠siconic.com

Does anyone know of a source for (or have) enough PDP-8 (the original "straight") front panel switches to fill in a front panel? I am working on a replica of the PDP-8 (non-functional) for a museum exhibit, and need to find either a source for switches or some that look close enough. If you have some you wouldn't mind parting with, please contact me with your asking price. If you know of a source, please pass it on. Thanks! -- 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 *

NeXTStation Color DSP cable pinout

by ian_primus＠yahoo.com

I recently accquired a NeXTStation Color, complete with color monitor and DSP box. Unfortunately, I don't have the cable to go from the NeXTStation to the DSP box, and therefore, I can't use the computer because the keyboard also connects to the DSP box. Does anyone have the pinout for this cable? Also, how does everything connect? I have seen various info on the internet that conflicts. I am assuming by looking at it that the monitor port is just a monitor port, and connects to the monitor through a standard 13W3 cable (came with the computer, but it Sun branded). Then the sound box would connect to the computer through the DB-15 on the back of the computer labelled "DSP" and to the DB-19 port on the sound box. Then the keyboard plugs into the sound box. But >from searching the internet, I have found things such as this http://www.obsoletecomputermuseum.org/nextcolor/monitor_cable.jpg that show a three headed cable that would connect the monitor to the computer, and to the back of the sound box. But then what would the DSP port be used for? And how would the computer get the signals from the keyboard? I'm new to NeXT hardware, so any help would be greatly appreciated. Thanks!

11/44 is alive :)

by jwest＠classiccmp.org

Thanks to all who helped! I checked out my backplane (NOW I see why the 44's always tilt up in the rack, so you can frequently get to the backplane wiring) and sure enough, missing NPR jumpers. I wire wrapped them back in (laughing at just how long ago it was since I had to use a wirewrap tool) and now - voila. The 44 comes up just fine, passing T, T/E, and T/A tests anyways. I can also deposit and examine a random memory location or two, probably a good sign. Now I just have to find out why it doesn't seem to think I have a TU58 attached...then get some RL02's up... Another question - I was perusing the net for what OS's I can run on the 44. I already have RT11 with TSX+ up on another machine, so on this one I was looking for something different. Being as my bent is multiuser basic machines (like HP2000 TSB), I was piqued by some references to EduSystem25 I think it's called. I got the impression it USED to be Poly BASIC, but that software was later acquired by DEC and turned into the EduSystem25. There was a link saying where EduSystem25 can be found, but alas, the link is dead. Does anyone know where manuals and media might be found for EduSystem25? Thanks! Jay West

I actually saw that guide today. The main difference is the amount of core memory the backplane will support, and, hence, the backplane slot layout for the system.

New find: pdp-11/05

by robinm＠rpi.edu

Hello, Today a friend of mine acquired a pdp-11/05 from our school's engineering department. Unfortunately, it isn't in too good shape. Fortunately for him, I've spent the last three years restoring (sucessfully!) a pdp-11/45. So I offered to help. However, this machine is somewhat of a different animal, so questions: Could someone scan the engineering drawings for an H217C stack? This is partly for my own edification (I have one such board in my machine), and partly because of the fact that this "new" pdp-11/05 has no core with it. Its engineering drawings seem to indicate that it wants 4 or 8kW of core (one or more of H213-H216), *not* the 16kW of a H217. (Granted, by placing two H214s into a chassis we get 16kW, but I digress.) That would have been enough to shut me up, but I looked a little further. It appears that the H213 (4kW) stack is a proper subset of the H214 (8kW) stack. The schematics appear to indicate that the H214 has all of the lines, bus connections, etc. as the H213, plus a few more. Indeed, it appears that if I were to place an H214 in the machine, but tell it that it was an H213, it would be fine (and see 4kW of course). Am I right? If so, the next question is, can I do this with an H217? (Drop in an H217C, and tell the machine that it's really an H214/H215.) This might sound like a gratuitous waste of core, which it is, but I happen to have another core board (not in my machine) that could be used... So anyway, the engineering drawings would answer this question really fast. If not, I guess we'll be looking for an H213-H216... :) Thanks, Michael Robinson RPI Electronics Club Vaxherd/PDP-11 Fixer robinm(a)rpi.edu

Thats a general problem on Ebay, seller tend to cover their listing-costs into the "shipping" or "handling" fees they charge. Your only chance to make this clear is a mail to the seller on this before you bid. Make clear that you will only bid if the seller follows the rates of e.g. USPS or some other shippingcompany.

Any old full height 360k drive perhaps? I have some half height 5.25 360K drives. They are working pulls from PC clones. I don't think I have any full height ones. Some (most?) are black, and many have that little imprinted asterick that designated the 360K "B" drive as opposed to the 1.2MB "A" drive. I don't know if these are IBM branded drives however, as many were probably NOT pulled from actual IBM PCs (some might have been). If you want one, just let me know. -chris <http://www.mythtech.net>

Kaypro II

by Robert_Feldman＠jdedwards.com

Because of a peculiarity in the Kaypro format (Fred Cisin has gone over this before, but I don't have the details at hand), you must format the Kaypro disk on your target PC for it to work. This formatting can be done on a PC with programs such as Xenocopy, MediaMaster, Convert. The disk formated on the PC can then be used in the Kaypro. You can copy files from native Kaypro disks to this disk, then read it in the PC with the software. -----Original Message----- From: Mike van Bokhoven [mailto:mike@ambientdesign.com] Sent: Wednesday, February 12, 2003 6:03 AM To: cctech(a)classiccmp.org Subject: Kaypro II <snip> - Does anyone know if it's possible to write Kaypro disks with a PC and 5 1/4 inch drive? If not - any hints on where to dig up software? <snip> Mike.

Differential SCSI vs. SE ?

by Fred.van.Kempen＠microwalt.nl

All, Doc writes: > I have a couple of DEC Wide-FWD conversion modules. P/N DWZZA-VA > Look 'em up, and if that fits your bill, I'll send you one for > shipping costs. I looked at the DEC StorageWorks documentation, and it seems that I will need the following: :: DWZZB is a Fast Wide Differential to Fast Wide Single-Ended SCSI :: bus extender and signal converter. It is 8 or 16 bit Fast Wide :: Differential SCSI on one side and an 8 or 16 bit single-ended :: SCSI on the other side. DWZZB is SCSI-3 (ANSI X3T9.2-10R3) :: compliant, can handle data rates up to 20 (16-bit) MB per second, :: and operates transparently to SCSI bus. The product fully supports :: all the latest SCSI-3 bus phases as well as all earlier standard :: SCSI compatible implementations, back to SASI. :: :: DWZZB is bi-directional in operation and can be cascaded. A :: maximum of two can be attached to a bus in a series. Termination :: on the single-ended side is user selectable. The 16-bit fast wide :: differential side features user removable resistors. DWZZB handles :: the more powerful 16-bit SCSI buses as well as 8-bit buses and :: handles data rates up to 20 MB per second on Fast SCSI. It is :: fully compatible with 2- to 5 MB per second data rates of earlier :: SCSI interconnects. It extends SCSI buses from 3 or 6 meters to 25 :: meters using synchronous transfers. :: :: DWZZB can be used to connect the widening range of available :: differential SCSI storage devices and subsystems to single-ended :: hosts. No changes are required to existing devices or software; :: the DWZZB does not occupy a SCSI bus node According to the document, I'd need the :: DWZZB-AA Standalone Product-includes built-in universal power :: supply for general purpose SCSI bus length and signal :: conversion needs, can be used with any SCSI-2 :: compatible device. or the :: DWZZB-MA Module for OEM use-includes basic module that operates :: at 20 MB per second and is fully ANSI compliant for :: embedded applications (power suppler and packaging to :: be ordered separately by OEM or system integrator). Does anyone have some of these available? Thanks bunches, Fred

cool find.

by cvisors＠carnagevisors.net

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Okay cool find for the day. I just got myself an Indigo2 R8000. and the cool thing is I actually got a copy of IRIX 6.5 with it, I now have IRIX media Yay! it also has another network card installed in the machine, plus some video capture board, but unfortunately with out the breakout box. at present just installing Irix on this machine, as the original install had /usr as a NFS share.. anyway a nice machine to add to my collection of way too much stuff. (already been told off from the significant other about it ;) ) - ----------------- I saw two shooting stars last night I wished on them but they were only satellites Is it wrong to wish on space hardware?

Sun tapes

by aw288＠osfn.org

I have a bunch of old Sun tapes I need to get rid of, as I no longer run any Sun-3 or Sun-4 machines. Most of these are real Sun distributions (although they look cheesy) of SunOS 4.1 and 4.1.1, plus SunLink and Openwindows. There also might be some third party stuff. I think all of these tapes actually have data on them, but I no longer have a suitable tape drive to verify them (so maybe expect a few to be flakey). Anyone need these tapes (about 13 1/4" QIC-24, I think) for cheap? For the lot - $8 plus shipping for 10512? I thik I also have quite a few unused 1/4" tape carts, also cheap. Real cheap. Contact me off list... William Donzelli aw288(a)osfn.org

Differential SCSI vs. SE ?

by Fred.van.Kempen＠microwalt.nl

All, Now that I inherited a nice set of StorageWorks enclusures with an HSZ40C controller, I might as well use it, no? I plan on connecting it to the primary file server of my "fun" network (also known as VAXlab, aka pdp11.nl) so I'll have more (and safer) storage there. Only prob is.. the HSZ40C has a diff-scsi port, whereas the machines have SE. Is this easily converted with a cable, or will I be doing resistor- balancing and/or use a signal converter box? Thx, Fred
