>2) What are the differences between the 4000VLC and the 4000-500? Are there >likely to be some serious gotchas in there? The VLC (as you know) is small, uses one low profile SCSI disk internally, has an external SCSI connector, supports a max of 24MB or memory and weighs in at 6 VUPs or so. There is no real expansion available. A VAX 4000-500 is bigger (coffee table size), usually comes with DSSI drives (although it can use SCSI with the right additional h/w) can have many disks, supports more memory (512MB max - 32MB min!) and runs at 24VUPs on a bad day (more if it is really a -700A or 705A). DSSI is available for storage and the box has a Q-bus. Whether any of this matters or not depends on what the VAX is supposed to do. If they wanted an OpenVMS compute engine, almost any cheap Alpha would eat both of the above for breakfast, so I assume that there is either a software constraint (e.g. VAX-only 3rd party s/w) or a hardware one (must use this Q-bus interface card).

Brian Instruments BRIKON Mdl 723 Floppy Drive Tester / Analyzer

by rigdonj＠cfl.rr.com

Does anyone here have access to one the model 723 floppy drive testers with the analog/alignment attachment (option R)? If so can you send me the pin out of the I/O cable for analog attachment? I think there's only six or eight leads on it? Joe

Regulators rarely fail in storage. If it is blown, it most likely blew while the power was on and any damage has already long since been done. That being said, there is a failure that can happen in storage that is related to the regulation. Many regulators, especially the TO-3 types need the screw holding them to the board to have a vary good connection. If this is bad, the voltage will go unregulated and it will over voltage. You should remove and check under these screws to look for corrosion and clean the surfaces. I recommend a star washer between the PCB and nut/washer. This should be checked on any electronics that has been stored. Often this is a good point to restore some fresh heatsink compound as well. The old dry stuff is less effective. The most common failure is the old electrolytics and the tantalums. I've seen flames from a blown tantalum. If you connect a voltmeter to the output leads of any regulators and watch the voltage as you bring the line up with a variac ( adjustable auto-transformer ), you should be able to catch any over voltage before it does any harm. ( note: don't use a variac on a switcher supply! ) Later Dwight

RSTS/E Manuals???

Keyboard adapter for ??

by lgwalker＠mts.net

I picked up an ordinary Fujitso KB at a thrift shop that had an adapter on the end of the cable. It's a small plug and the only markings on it were the common I/O arrows on the business end. One side is the regular F 5-pin Din but the male side is about halfway between a regular din and a PS/2 sub. It is in a 6-pin configuration but the pins are much thinner than usual. It only has 4 pins which would square with the 5v, grnd, clock, data requirements but it could have a pin(s) broken off since they're fragile and protrude from the shell about 3/8". Clockwise the 1 and 3 are missing. There's no center lock. Anyone have any idea of what this might be for ? Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

CPM-8000 running

by dwightk.elvey＠amd.com

Hi Chris Groessler and I have been working with the CPM-8000 images that we found on the unofficial CPM page, along with manuals and such found elsewhere. Last night, I was able to get the CPM-8000 prompt and execute both commands that I tried ( DIR and USER ). There are still some minor issues but things should be moving right along ( why can't programmers realize that initializing variables is an important part of any program? ). I want to give thanks to Hans, without the hardware manual he scanned, I wouldn't have been able to figure out the address decoder PROM in my Olivetti M20 and find out how to bring my machine up to 256K of RAM ( needed by CPM-8000 ). We still have some work to do ( building up the disk with all of the files ) but it looks like a down hill trip from here. Later Dwight

Altair-what do I do first

by kapteynr＠cboe.com

All good advice so far -- but one caution I forgot. My experience is that the CMOS chips from this period are THE MOST STATIC SENSITIVE chips that there are. It is much easier to damage these whith inappropriate handling than any modern stuff. Use paranoid static handling precautions. Since I usually work on these machines on those cold (dry) winter days when static forms easily, I also use a humidifier in the room where I work. -Rob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of J.C. Wren Sent: Tuesday, September 24, 2002 8:08 PM To: cctalk(a)classiccmp.org Subject: RE: Altair-what do I do first A less painful way may be to lift the output pin of the regulator >from its via. Or (and this is evil, but works, and is can be better than losing all your unsocketted chips), cut the trace after output of the regulator. You can always use a piece of foil tape or wire to effect a repair.

The voltage regulators are on each card. And this means that a defective regulator _on a card_ will wipe out all the chips on that card, and may even put high voltages onto the bus lines and damage other cards. Therefore, do as suggested and get the unregulated PSU working first. Then take the cards (one at a time) and remove all socketed ICs. Make a diagram first, of course if you don't have the schematics/layout diagrams for that card. You'd better hope that the expensive/rare ICs (CPU, ROMs, RAM, LSI I/O chips) are socketed. Then put the (essentially bare) card in the backplane and check the outputs of the regulators on that card. Repeat for all the cards you have. Put the ICs back into a card before starting on the next one (unless you are a lot better organised than me!) Then, and only then do you put populated cards into the backplane and start testing logic functions. -tony

RSX-11 Kermit file transfer of binary files...

by bqt＠update.uu.se

Unfortunately I (somehow) missed the start of this thread, but I figured I might as well jump in. I don't even know for sure who asked the original question, but I hope this gets to whoever is interested. First of all, you need to set kermit to transfer binary files in order to transfer tasks (I figure it handles this if you allow it to automatically decide the mode as well). Second, kermit-11 can send attribute packets, which tranfers RMS information, along with the file. Third, KERMIT-11 is somewhat buggy. I wrote a patch or two to remedy the most obvious errors (which crashed KERMIT-11 if attribute packets were sent). However, I got tired of this whole thing, and wrote a program similar to uuencode/uudecode for RSX, which preserves everything, while converting to/from plain text files. I called it COD, and it's in MACRO-11. Not in all respects a beautiful program (the source, that is), but it works very nice, and it's free. Using this, you just throw your file at COD, transfer the text file, run it through COD, and you have your file back. It retains all attributes, contigous state, and some other meta information as well (such as file protection). If anyone need it, it is free, available in source at ftp://ftp.update.uu.se/pub/pdp11/rsx/tools/cod/ Johnny Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt(a)update.uu.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

2.4Mb 5 1/4" floppy drive?

by rigdonj＠cfl.rr.com

I was scrounging around last week and found a pair of HH 5 1/4" floppy drives that are marked "2.4" next to a disk symbol on the front. Just out of curiousity I picked them up and checked <http://marina.mfarris.com/floppy/Hitachi.html> and sure enough they're 2.4Mb floppy drives! I've never heard of these before. Does anyone know what the disk format is or where these are used? The drives are Hitachi model FD532EIU. The label on them says that they're made for IBM. They're in some sort of a plastic sled. Joe

Pixel Machines

by pat＠purdueriots.com

There's a AT&T/Pixel Machines model 964d 'video thing' down at university salvage, and I was wondering if anyone had any information on them. It appears to have been produced in 1989 by an offshoot of AT&T called "Pixel Machines". Using google, the only result I can get that matches "Pixel Machines" and 964 or 964d is a thesis of some sort, which doesn't have a whole lot of useful information on the beast. As far as I can tell, it's some sort of redering/raytracing 'thing', and from its outputs, it appears like it might output NTSC video. I'm not sure yet if I want to bother lugging it up here - it's about 2ft x 2ft x 1ft in size, and looks like it might weigh as much as a small car. Thanks for any information you guys can turn up, -- Pat

Consider your self lucky, my wife is understanding. As a result, I'm the one that thinks I've got too many old computers. I've said it before, and I'll say it again, collecting old computers is a disease! DECitis is one of the more extreme and dangerous varients of this disease. Developing DECitis can be especially dangerous if you already suffer from Bibliomania. If you think I'm joking, think again. Zane PS at least the disease isn't as distructive as some.

2.4Mb 5 1/4" floppy drive?

I did some searching on the 3174 and option 1048 for them is a 2.4Mb drive so that looks like that's where they came from. Later I checked the drives closer and I found a disk in the one that I hadn't looked at. It looks like a standard 5 1/4" floppy disk. It had a plain white label on it with no brand name.

I've searched Google and IBM's site for the number but didn't find anything. I found these drives in the same pile with some IBM RS/6000 cards. Does anyone know if the RS/6000 uses anything like this? I'd never heard of a 5.25" 2.4MB floppy before this, but I know that some models of the RS/6000 range and I believe also some PS/2 range had so-called "2.88MB" 3.5" floppies. I have one here (the drive,that is, not the RS/6000). They look just like ordinary 3.5" HD floppies except for the extra media sensor. They can use normal DD or HD disks, or special ED disks which have the media sensor hole in a different place to HD disks -- it's slightly further from the bottom edge, so if you put an ED disk in an HD drive, it would be seen as DD. However, the coating is a special barium ferrite rather than the normal cobalt ferrite, and for ED, the drive uses a vertical recording technique developed by Toshiba instead of normal longitudinal recording. If the disk in the drive you've found looks just like a normal HD floppy, that's what it is -- not an Extra Density one.

Xerox 820 lives!

by acme_ent＠bellsouth.net

Greetings to all -- About a year ago, Joe Rigdon very kindly gave me a number of old machines (thanks, Joe!), among them a Xerox 820. At the time he gave it to me, the unit didn't power up, but today I finally found the time to give it a second look. After I reconnected a loose lead inside the box it came to life! This is my only machine with 8" disk drives, so I'm interested in finding a good use for it. I could use some help from the list members, though. I found *no* technical data via Google, and have *no* real docs for this beast. After poking at the 820 for a bit, here's where I'm at: --> The "B" drive is faulty. Disk initialization fails, and it will not consistently read disks created on the "A" drive. Any pointers on replacement drives? Even if a thorough cleaning revives this drive, I'd like to obtain a spare. --> Assuming I can't revive the "B" drive or find a replacement, how can I duplicate diskettes? The CP/M utilities all seem to want two drives in order to do their job. --> Two of the boot diskettes which I have boot up a pretty normal looking version of CP/M 2.2, with a normal "A>" prompt, but another diskette displays the following upon boot: "Good Day! ZCPR 2.04 SYSTEM READY" and the prompt is "A0>" (obviously user group 0). What is this "ZCPR"? --> Some of the utilities on the boot diskettes (FMT, for example) refer to hard disk drives. What's involved in attaching a hard drive to this system? --> The flimsy "User Manual" which I have states that the RS232 port may be configured to attach to a terminal or to a modem. How? --> Lastly, does anyone have any documentation on this thing? If you can part with it, I'd be glad to pay a fair price. Thanks in advance for any help you can provide. Although this system doesn't appear to be special or unique, it does seem to be a sort of nice, friendly critter, and I'd like to put it into use. Later -- Glen 0/0 If I am not for myself, then who will be for me? And if not now, when? -- Pirkei Avot

AES CPM on E-Pay

by lgwalker＠mts.net

An interesting early CPM computer, complete with monitor and fdds. AES is Automatic Electronic Systems, a Montreal company that was founded by Stephen Dorsey who then sold the company and went on to found Micom. He put out a remarkable Word Processor/computer called the MICOM 2000 before the Apple got out of Woz's garage. AES must have mfrd. this after Dorsey sold it. No date given but likely pre 80. Wish I could afford it. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2056611909 Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

Slightly OT: HP 9000/C160

by pat＠purdueriots.com

I've managed to pick up a memory-less HP C110 that was upgraded to a C160. Looking at Kingston's site, they want way too much for new memory for it. Does anyone have extra memory, or a source for memory? I've also got an HP Apollo 715/50 - is that memory compatible? Thanks for the help! -- Pat

An S-100 Power Plug - Please?!

by dwightk.elvey＠amd.com

>From: MTPro(a)aol.com >One more time. Anyone?! Would anyone please have an extra power plug they could sell me for my generic S-100 computer? Somehow mine must have gotten given away with other misc. cords. It's the kind with two sort of oval female prong inputs on the computer end. Anyway, I'd be happy to furnish a picture to anyone who needs to verify. I haven't had it up and running for a couple of years now, and I would like to. Thank you, David > Hi I have an Allied catalog that is a couple of years old. They call these SVT cords. They have several listed: manuf Manuf# Allied# Length Price Alpha 543 663-7082 7'6" 4.62 Belden 17952 612-3569 8' 5.38 Belden 17280 612-3677 7'6" 4.84 Hope this helps Dwight

Don't remember what their sources were. You're not the only one who'd be interested, though. The figure I always heard for total sales of the 4A was 2-3, maybe 4 million. Not sure how accurate that is, as TI had to eat a bunch of returns when they pulled the plug, but it's probably in the ballpark. There are still piles of them around, anyway. jbdigriz

Televideo 912C and General DataComm Gen Net Terminal Server

by fastluck＠email.com

I have a Televideo 912C and a General DataComm Gen Net Terminal Server. I want to make these two machines talk to each other. I think it would be really cool to be able to display a Trek game or something. But I have a couple of problems. First of all, I'm mostly a PC guy. I don't know anything about these machines. Secondly, I don't even think the ports on the back of the Gen Net are RS-232C. If they are, there's a protocol problem or something, because what gets echoed back isn't what I type. (I type several characters before one is echoed, and the echoed character is usually an odd-looking non-character.) I don't know the password on the server, and I don't know how to operate its control keyboard. Here's something else weird--you have to actually remove the front cover to turn it on and off! Here are some pictures of these machines http://mywebpages.comcast net/fastluck1/Televideo.htm. Check out the terminal--it looks really cool. Can anyone give me information on operating these machines, or point me in the right direction? Thanks in advance, John

"Orders that total less than $25.00 may be subject to a handling fee. The amount of the handling fee will be the difference between $25.00 and the total amount of the order." "The shipping cost on any order will be determined at the time of shipment. All shipments are F.O.B Fort Worth, Texas. Shipping method, in most cases, is the customer?s choice."

what drive does an RV02K WORK disk go in?

by healyzh＠aracnet.com

Ouch! Good luck. I wonder how rare one of those are. I've heard of them (I think), but I'm pretty sure I've never seen one for sale. Depending on how badly you need the data, you might want to consider looking for a professional data recovery service that might have a drive (unless you're lucky and someone on the list can do it for you).

I would offer to repanel that wall for them (even the entire room to make sure it matched) if it meant laying my hands on one of those. Is the family selling the house? If so, stay in close contact, and even talk to the realitor and see if you can arrange something with the buyer to take custody of the machine. -chris <http://www.mythtech.net>

Any Sanyo/Everex/Zeos 386 LT owners ?

by lgwalker＠mts.net

I finally got serious about my Commodore LT and did some major Googling thru the NGs. Following some hints I found, I got what I think is the pinout for the 8pin mini-din power plug on the Zeos site. Sanyo appears to be the mfgr. Anyone on the list have one of these beasts ? 3 of the pins take 15v and I'd like to find the amperage requirements. Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com
