Some people need help!

by MTPro＠aol.com

Hello, I received both of these message yesterday and I cannot help the people. Anyone have an answer for them? Please respond driectly to them and not me, thanks: ----------------------------------------------- I am looking for a converter to convert some old Wordstar documents. I'm wondering if you might have one handy and could email it here (Sydney, Australia). Or else, do you have any idea where I could get one on the web. I have had a search but with little precise luck. It looks like Microsoft offers a massive 12+ Mb solution to everything which likely would contain it. I will come at that if needs be but thought I'd first try to just get a simple worstar-only translator if I can. Years ago I used to have such things myself but I no longer could locate it now. Kind Regards John Byrnes, Geologist byrnesj(a)minerals.nsw.gov.au ----------------------------------------------- Ref: xerox computer/ser.#m92-013062/1983/bios ver. 5.00 Would you have any info on this machine? I am not certain if it works so I need to obtain it's original operating system or at least a start-up disk. I would like to try and move it for a friend. He has a pawn shop, and this is a case where he got the shaft. A little joke. He is a fair person as far as I can see, and I just want to help him if I can. Any help you might send my way about this machine would be helpful. All it has as far as a model is xerox both on the monitor, and the cpu. I needed to type aa: to get it to recognize the floppy drive of which it has two 51/4" drives. The monitor is connected to the cpu with two wide insulated ribbon cables. the serial, parallel, and keyboard ports are at the back of the monitor at the bottom. It is a different configuration than I am used to, but it seems to work. I don't believe it has a hard drive, but I haven't taken the hood off to check. The drives search the disks I have put in, but to no avail. I think it might be that cm/p operating system, like the old kpro I have, but there again I am not certain. I hope that what info I have given is sufficient to identify this machine. Thanks , Jimmy Dean Fisher ,phydauex56(a)yahoo.com

Mac Portable problems

by RCini＠congressfinancial.com

Hello, all: I decided to pull-out my Mac Portable to charge it after it being on the shelf for about 1 year. I put the battery in and plugged in the power adapter. As soon as I insert the battery, the unit immediately starts up but doesn't boot and I get lots of vertical lines on the screen (in no discernable pattern). I know that the screen has a few defective rows near the bottom but had no other issues the last time I used it. It wasn't stored in extreme temperatures (either cold or warm). I hope that some of the screen drivers didn't go flaky on me. Since I haven't used it in a while, I've forgotten a lot about it. Does this have a reset button on it? Any thoughts on what else to look for? Rich ========================== Richard A. Cini, Jr. Congress Financial Corporation 1133 Avenue of the Americas 30th Floor New York, NY 10036 (212) 545-4402 (212) 840-6259 (facsimile)

How to Print CD Label

by jhfinepw4z＠compsys.to

I need some help with a ".tif" file. A scan was made of a CD label. The label can be printed on a laser printer and the result is great, but in the wrong position. I am a dummy using Windows 98 SE. When I use Windows Explorer and click on the file name, up comes the image of the label. It can be rotated, but there does not seem to be anything that will allow me to move the image sideways nor down so that the image is printed on top of the label. Can anyone suggest what I need to do? 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.

Classic Assumption

by doc＠mdrconsult.com

Hey. This is sort of long, but relates a major wake-up call for me. I have a J-Series RS/6000 7013-560 that I rescued from Goodwill awhile back. It's an awesome machine, and one of my favorites. My company works occasionally with/for a firm who produces traveling AIX classes. They move machines from city to city, doing one-week IBM curricula. About 15-18 months ago, their shippers lost 8 of 12 machines on the way to San Antonio. My boss & I rented them all our equipment - 6 RS6ks and a couple of terminals - for a week to keep the class from folding. The 560 went, against my better judgment. When the computers came home, the first thing I did was reinstall a clean OS on each one. It's amazing how many ways students can hose an install. The 560 stays on 4.3.2, for sentimental reasons. It wouldn't load properly. The BOS would install with no errors, and come up on reboot to a 554 error code. Unable to find bootable device. I swapped drives, I reset jumpers, I verified termination, I unplugged everything that spins. I even found a replacement IBM CD-ROM. I eventually narrowed it down to the SCSI cable. (A J-box internal SCSI cable is a nightmare to behold, and hell to replace. Let alone _find_ one) Last week I picked up a 520 and swapped the cable, then the SCSI adapter. Same problem. The 520 also came with full hardware docs and diagnostic floppy set, so I ran a full suite. Everything checked out, except for that 554 error. I finally decided to load v3.2.5, which also came with the 520, just because. When I pulled the 4.3.2 CD out of the caddy, where it's lived for 2 years, I found an ugly little dob of some pink gel on the data side. I cleaned the disk, put it back, installed AIX v4.3.2 on my 560, and it's running happily right now. I get so accustomed to old hardware having issues, and especially after it had been transported, and unsupervised lusers had their hands on it, that I completely bypassed some elementary checkpoints and lost the use of my machine for a year. Bah. I'd feel like an idiot if it wasn't so, ummm, "classic". Doc

ST-225 help needed

by acme_ent＠bellsouth.net

Hope someone can help . . . I have two Seagate ST-225 drives and a WD1002SWX2A controller. Both drives have previously lived in XT-class DOS-based PCs. One of the drives is bootable, the other is not. What I need to do is set both drives up in the same PC, booting from the bootable drive (duh) so that I can extract the data from the non-bootable drive. The object of the game is to move the data to a modern (Duron-based) system. I can't boot from a floppy disk drive due to a fault in the motherboard, but I do have a SCSI controller and hard drive in the XT system. I can move the SCSI drive to the newer system once I can get to the data on the non-bootable ST-225. What is the proper configuration for the ST-225 drives and the WD controller? Any help is greatly appreciated. Glen 0/0 If I am not for myself, then who will be for me? And if not now, when? -- Pirkei Avot

Almost certainly, the expected drive geometry is embedded in the partitioning software which may or may not be tightly coupled with the low-level formatting software you reference above. With source code, you could turn off any features you don't want, and change the tables as needed (although you *could* just ignore the rest of the drive and only use the first few megs; unlike an ST506/ST412/ESDI/SMD drive, modern SCSI and IDE drives present a virtual model of tracks and sectors because they have a variable number of sectors per track and you can't easily *know* what physical cylinder you are on). In a similar vein, between myself and some folks in Michigan, Finland and Germany, we've managed to tweak the partition tables for a Commodore D9090 disk drive which happens to have an OMTI SASI<->ST506 bridge controller so that it can use other drives like the ST225. One project that I have on my long-term plate is to tweak the ROMs to handle embedded SCSI drives (the formatting and partitioning software is *in* the drive and run by one of its two microprocessors; the PET is completely out of the loop - it just sends a "N0:diskname,nn" command to the drive and the drive does all the hard work). It's not exactly the same situation, but there are similarities - you have to understand the formatter to know what changes are needed. > >> >Additionally, whatever (low level) formatting software comes with the > >> >host might or not might not work with an embedded drive... > Since whatever replacement drive that I get will most likely come from > a MS-DOS machine I'll almost certainly have to LL format it.

Again I don't know if I actually have the files. I got a large > box of SW with the system but loaned it to someone and now he can't find > it. Generally speaking, you only have to LL format an embedded SCSI disk if you are trying to whack and refresh the bad block table because the disk is aging or you need a different sector size. LL formatting has to be done *before* partitioning; it's not the _same_ as partitioning. Think of it this way - in the PC/XT DOS world, you LL format an ST225 drive with debug the command "G=C800:5" that jumps into the controller's BIOS You partition with fdisk, and you high-level format with "FORMAT". Three seperate steps. If your embedded drive works on some other system, you can probably jump right to "partition" under CP/M, unless for some strange reason, you can't use 512 byte sectors (almost certainly what your SCSI drive has on it now, but I _have_ seen other sizes in non-Intel systems) > What do you think of trying to use some kind of removeable media > drive such as an IOMEGA ZIP drive or an old Syquest drive? Should be no different to your host than any other embedded drive. I don't know about LUN issues, but I wouldn't expect them. I have both a SCSI ZIP and a 44MB SQ555 (just got a stack of cartridges from the Micro Center for $3 each, new off the bargain table!) and have had no compatibility problems on Suns or Amigas or Macs or PeeCees (would love to try them out on a PDP-8 but I'm still searching for an OMNIBUS SCSI controller). > Thanks for your advice.

Good luck. -ethan P.S. - found an interesting historical document on Segate controllers and drives at http://www.mm.mtu.edu/drives/seagate/misc/pc_hints.txt If you didn't used to have to mess with PeeCee drives 10-15 years ago, there's some good information in there. __________________________________________________ Do You Yahoo!?

HP-HIL update

by roosmcd＠dds.nl

You've just got to love Google: "You can! The 715/80 has both HIL and PS/2 signals in this 10 pin connector. Here's the pinout of the adapter box (no guarantee, of course): | Pin Signal | Workstation HIL PS2 Mouse PS2 Kbd ----------------+---------------------------------------- HIL +12V | 1 1 HIL SI | 2 2 HIL SO | 3 3 GND | 4 4 3 3 PS2 Mouse Clock | 5 5 PS2 Mouse Data | 6 1 GND | 7 3 3 PS2 Kbd Data | 8 1 PS2 Kbd Clock | 9 5 PS2 +5V | 10 4 4 " So that's what inside the UKP 19.50 cable.. Can anyone please confirm if this really works? Or if it just blows up your workstation (pictures!). It looks like my C110 doesn't have all the pins in the HP-HIL socket. greetings, Michiel

new retro computing

by bfranchuk＠jetnet.ab.ca

Still plugging away of a TTL style cpu in a FPGA I have found some terminals localy. How ever I am still looking for a serial RS232 mass storage device in Canada that is not tacky looking like a old Pee-Cee. For now I am using a old 486 with a serial program to download bootstrap programs but looking around since summer is a good time to collect stuff. Baud rate of 300 or better would be nice. -- Ben Franchuk - Dawn * 12/24 bit cpu * www.jetnet.ab.ca/users/bfranchuk/index.html

FSOT: Lotus 123 v 1A for the Wang Proessional PC

by rigdonj＠cfl.rr.com

I picked up a load of old software the other day and found a copy of Lotus 123 v 1A for the Wang Proessional PC. It's in the original boxed set and is like new but it's missing a couple of the disks. The Tutorial disk and Utility disk are there but the others are missing. If anyone wants it I'd like to swap it for MS-DOS version or a CPM version (if there is such a thing) as long as they're in the same condition. Again this one is in perfect condition and is as good as new with no marks, tears, wear, etc. If interested, contact me directly. Joe

Part of the problem is that the HP controller in the drive expects to see a high-level format on the drive. Back around HP-UX 7.0 I found some arguments to mediainit (-GD I think; the finding was done by running "strings" on the mediainit executable and looking for a getopt(3)-style option parsing string) that got it to tell the drive to do a low-level format and write a new high-level format as well. Made the disk portion of a 7946 usable again after going "bad" and being formatted in a PC for testing. -Frank McConnell

NES Special Cartridge Finds

by jrkeys＠concentric.net

Well I now have two of the special Gyromite cartridges with the Famicom board and Famicom-to-NES converter inside. After reading about these and the 4 other cartridges that have these special boards I started looking for them at my normal stops. Of the 4 cartridges I purchased 2 had the boards inside. With these I can run Famicom games cartridges on the NES box.

If you try to call SGI nowadays, you won't get far without a support contract and a serial number to match. Otherwise, you tend to just get referred to sales, who will try to sell you support (or an OS upgrade or whatever) if the machine is recent enough to be supportable. You might have some luck if you can find someone with a support contract who regularly sees the engineer. The older ones tend to be quite knowledgable and may even have worked on such a system or know someone who has -- and might put you in touch. Otherwise, the best resources are the comp.sys.sgi.* newsgroups, which are fairly active and populated by a number of SGI employees as well as enthusiasts. -- Pete Peter Turnbull Network Manager University of York

PDP 11/44 startup: ?CP didn't start

by felten＠vaxnet.de

Hi, I just repaired the powersupply of my pdp 11/44 and cleaned the box. When powering up, the console terminal only shows: (Console V3.40C) (Program) (Console) ?CP didn't start >>> I guess this is bad news.... Does it mean Central Processor didn't start? (just guessing, but the RUN- light stays dark, DC-LED is on and the key works) Since i don't have a manual for the 11/44 i really don't know where to start. I searched the web for a scanned KD-11-Z manual, but found nothing. The actual configuraton is minimal, I insterted the processor, cache, ram, CIM and bus terminator like this: A - B - C - D - E - F M7090 X X X X CIM / CIS (option) X X X X X X CIS (option) --------M7093-------- FP11-F FPU --------M7094-------- KD11-Z data path --------M7095-------- KD11-Z control module --------M7096-------- KD11-Z multifuncion module --------M7097-------- KK11-B cache --------M7098-------- KD11-Z UNIBUS interface --------M8743-------- MS11-PB 1 Meg Ram X X X X X X MEM (option) X X X X X X MEM (option) X X X X X X MEM (option) X X X G X X UNIBUS M9302 X G X X UNIBUS G=Grant card. I do have the "processor handbook pdp11/04/24/34a/44/70" (printed in 1981, EB-19402-20) and tried some of the console commands. HELP works fine and gives a lot of HELP-text, but doesn't help much: all other commands tell me ?CP didn't start. I tried using the processor without FPU and disabled cache, but nothing changes. All DIP switches and 'Jumpers' (soldered) are still in default position. What can i do now ? Any idea is very welcome.... Regards, Lothar PS: Would it be usefull to anybody to scan the (entire?) processor handbook? I don't know how usefull this book can be to someone else...

What's the value of an rtVAX 4000-300 with no drives?

by glenslick＠hotmail.com

At a surplus store today I saw a couple of rtVAX 4000-300 boxes. I don't know anything about these types of systems. Are they interesting to people on the list? What is their value without any disk drives? They were marked $75 each. They had KA670-BA cpus, which I guess is standard for that box according to some info I just found googling around. They both had TK70 drives and at least one had a TQK70 board installed, which I guess is the controller for the drive. I'm not sure how much memory they had. -Glen _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com

I once attempted to repair one of HP's HP-IB hard drives used a Vertex drive internally. I THINK it was a V160 but I'm not sure now. I never did find a replacement that would work. IIRC I tried other brand drives but I couldn't LL format the new drive with the normal user stuff from HP so I don't know if the replacement drives were incompatible or ?? or if the replacements failed due to my inability to LL format them. I suspect you'll run into a similar problem. In addition, you'll lose all your SW if you replace the drive. If I were you I'd do my best to get that drive working again. The fact that it spins up initailly is a promising sign. I did look through my HP disk drive notes but I couldn't find anything that told what model HP used the Vertex drive. If you find a useable replacement or manage to resurrect that drive I'd be interested in hearing what you learn. Joe

List Change Updates

by lists＠subatomix.com

The first pages of the new ClassicCmp web site are up. It isn't much, but at least the correct instructions/forms for subscribing are there. Expect more in time. The site will be kept simple and (mostly) text-only, just like its predecessor. Comments/criticism are welcome. A few issues have popped up for people who are subscribed to both cctalk and cctech. To solve these, the following changes will be made shortly. These changes will _only_ affect people who are subscribed to _both_ cctalk and cctech. - People who haven't disabled mail delivery for either list will be unsubscribed from cctech. This stops duplicate mail. - People who have disabled mail delivery for cctech only will be unsubscribed from cctech. This stops off-topic messages sent to cctalk from forwarding to cctech without moderation. - People who have disabled mail delivery for cctalk only will be unsubscribed from cctalk. Other methods are in place to make their cctech posts forward to cctalk. - People who have disbled mail delivery for both cctalk and cctech will be unsubscribed from cctech. This prevents any issues if/when they decide to get ClassicCmp mail again. With the recent list changes, subscription to both cctalk and cctech is unnecessary and can create problems. -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic.

Instead you have to use an XYZ display or couple it to a 1600. Give me a shout if you need the part numbers for the probes or other info.

Old Macs - ROM p/n's, etc...

by kd7bcy＠teleport.com

It's been a long time since I've done anything with my really old Macs(128k, 512k, SE), so my memory is really straining here. Can anyone point me towards some web sites or maybe post info on which ROMs are which, various P/N's, and other useful info. I'm trying to build a system for a friend that wants to play with an old Mac. I have an old Mac case with an unknown system board or ROMs, but it doesn't have a floppy drive in it right now. I have a nice little pile of 800k drives, so I need to know which chips to look for when I go searching for my Mac Plus ROMs(I think I still have at least two lose sets around). Links to places with software would also be useful. Hmm. I'll probably have to setup my LC to make the disks for the system. Used to be that I could identify almost any Mac part from 50 feet... OK, maybe closer for the IC's ;-) I haven't touched them in so long I can't remember anything. I guess I can blame it on my iMac(I named it Thumper because it has an iSub behind it - the whole thing would bounce around the table back when I was using MacOS 9 with the iSub controls. Still nice sound with X, but not quite as much. Gotta love that green jellyfish look at night...). -- /------------------------------------\ | http://jrollins.tripod.com/ | | KD7BCY kd7bcy(a)teleport.com | \------------------------------------/

New (but selling used) computer shop, and hauls

by Mzthompson＠aol.com

There seems to be a number of shops springing up around here selling used Wintel. I try to visit each new one just to see what is what. Most times, one visit is enough. The latest one was an experience. The owner knows absolutely nothing beyond Intel. On the first visit, he took me to one back room. It is full of of Apple stuff and more. He mentioned some keyboards in another back room and said they use a modular phone plug. We went for a look and he held one up with the keys facing me. I told him to look at the tag, it should say LK401. His mouth dropped open. Also had a couple IBM model M keyboards. I was then out of time and had to leave. On my next visit I made a couple of offers and picked up some stuff. The first was the box full of LK201/401/402 keyboards. Just over a dozen for $5 for the box. Also got three Apple IIc's with power supplies, but no monitors nor mice. I suspect they are there if I were to dig deep enough. A friend wanted these and was content to get just the machines for $5 each. A rough list of known Apple stuff remaining is 6 SE's, 6 ImageWriters, 5 or 6 external drives, 3 GS's, and a scanner. There was three LaserWriter II's the first time and he seemed willing to sell them for around $10 each. However, I goofed by not taking them then and there. Someone offered him $50 each before I got back. My friend and I are trying to decide what to offer for the remaining Apple pile. After having sold some stuff (i.e. cash in his pocket), he was eager to show me some more old stuff in the basement. He mentioned having a lot of terminals down there and I assumed might be DEC to go with the keyboards. Nope, most it was absolutely total junk. He is quite proud of his store and proud of the fact that he is doing a booming business selling internet ready 486 machines for $50. A lot of those sales are made because he is willing to extend financing to his customers. Yep, that's right, customers financing a $50 computer. He wasn't too happy when I told him I give them away because I got more of than I know what to do with from people bringing them by all the time and other sources. I have since been told by a more 'upscale' store that he is bugging them all the time, wanting technical advice and the like. Oh well, each to his own. Mike

Bootstrapping a CP/M system to usability

by jhking＠airmail.net

This one is simple. 1) Get a 5.25" drive for your pc. 2) Download a copy of 22 disk. 3) Download any cp/m stuff you want 4) Use 22 disk to format a floppy as Osborne DD or Kaypro DD 5) Copy the files to the floppy 6) Stick the floppy in your 1571 Keep the 22-disk handy as you can transfer the other way as well. This is how I moved boat-load of cp/m stuff to my pc about 15 years ago when I converted to the dark side.

SGI IRIS 1400 (longish)

by aek＠spies.com

Does anyone have any info on these systems? There doesn't seem to be much information left, and very little can be found on the web. -- There is a VERY detailed FAQ that I helped write about 10 years ago that gives all the service passwords, switch settings, board types, et. http://www.futuretech.vuurwerk.nl/iris-faq.html is one place to find it. You might also try emailing the guy that just sold the 3130 and all those 24xx series boards on eBay and try to get copies of what he has before he ships it, or email the guys that bought the stuff.

CRT problem

I remember when I was a teenager and started fixing old tellys, that many of them had a flat laminated glass sheet, about 1/4" thick, in front of a plain CRT. The laminated glass was mounted in the cabnet, not bonded to, or even touching, the CRT. So that might be a reasonable thing to do in this case. Polycarbonate might be even better (and easier to handle). -- Pete Peter Turnbull Network Manager University of York

Latest Haul^H^H^H^H Delivery

by Mzthompson＠aol.com

It's nice once you finally get 'em trained. My daughter's friend knows I am a computer packrat. She had a couple things left behind by an old boyfriend. She took them over to my daughter who in turn gave them to my wife who brought them home and delivered them right to me. I now have two Cisco Catalyst 2900 series XL switches. One is a 2912 (12 holer) and the other is a 2924 (24 holer). Mike

Indianapolis Hamfest Haul

by Mzthompson＠aol.com

Many did not think it was a great hamfest this year, but if a whole carload of stuff hauled home is any indication then I say it wasn't bad. One good item was a Compaq Portable III, good clean condition, fully working, and had the internal modem installed. $5 This year I stuck around a little longer which means good deals on stuff they don't want to pack back up. One dealer had two eight foot tables full of customer returns and other 'as is'. I saw one item in particular and made an offer. He counter offered with a price for the entire contents of both tables for less than $10. I said what the heck. So far everything I have tested seems to work fine. I suspect a lot of customers try to install it themselves and just don't get it right and return it. Then there is the stuff that is pitched as it all winds down. A friend and I were standing next to a trash barrel when someone brought over some stuff. We grabbed some items. Among that was two full tower PC cases, and a old 486DX2/66 desktop. Turns out the 486 is a good machine for testing various components, so it has found a home on my test bench. Also a couple ATI video cards that are the same card as in the machine I am writing this on, the same right down to the firmware numbers on the EPROMS. It's nice to have some spares. Mike

Todays Find

by jrkeys＠concentric.net

At a auction today I purchased a lot to get a Mac Performa that was in one of the 3 boxes that made up the lot. Later I was loading stuff on dolly to haul out to the van and found a HP 97 calculator in a leather carrying case. In the case was the calculator and two little notebooks marked HP-67/HP-97 Games Pac 1 (with 23 games) and the other was HP-67/HP-97 Standard Pac (with 14 ). It's missing the charger (the batteries are dead) and there are no manuals. There was 6 19" Sun monitors left by another bidder and I picked up one of them, it's a model GDM-1962B.

[possibly OT]: Tektronix 466 - spares needed

by philpem＠dsl.pipex.com

Hi, A few days ago I picked up a very nice Tektronix 466 storage oscilloscope, complete with service manual. Catch is, I don't have the operator's manual. The service manual is thick with schematics and parts manifests, a fair bit of technical info ("this part does x function", etc). No real information on how to actually *use* this thing. I've worked out what 90% of the controls do by trial and error (that, plus the fact I used another scope before this one), but the storage section and some of the trigger section still eludes me... Scanned images or photocopy prefered, original manual would be even better. Also, it seems to be missing the blue cover that goes over the front panel and a set of Tek 1x/10x probes that were supposed to come with it. Anyone got a 466 as a junker they wouldn't mind parting out? I've been told Tek abandoned this scope a long time ago... Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Bootstrapping a CP/M system to usability :)

by archer＠topnow.com

I'm suffering from what one might call the "first program" problem. That is, I want to download CP/M programs (editor, assembler, and BASICK for starters) from the 'net and transfer them from my PC to my "CP/M" machine (A Commie 128 running CP/M+) to save on floppy for later use. I can boot CP/M+ on Commie, but the distribution is very minimal. It doesn't even include ED. It does have PIP, if this is useful, but no MAC, BASIC, or any other goodies that might be used to pull in xmodem or some other file transfer program into the machine and thus create a mechanism for transferring binary files into the machine from the PC. This must be a common problem, but surprisingly a web search yielded little insight on how to get the "first file" in. My extreme ignorance of CP/M at this point in time is not helpful either. With Apples, I know there was a trick to basically feed a BASIC program in from the serial port as if it were entered by the keyboard. With Commie-doors, there's the XE1541 cable and software to do the trick (but I don't think it can write MFM as needed by C128 CP/M mode.) Is there any similar "tricks" for CP/M? Without an assembler I would need to get a binary file into the CP/M floppy somehow. I don't have a 5 1/4" floppy drive in any PC but would consider scouring the Junque places for one if that could write files on my PC readable on CP/M. Or maybe I'm missing something and it's all so simple that nobody bothers to document it? Thanks for any clues. I want to be conversant with CP/M. Something to put on my resume. ;) -- Ross which is surely very common but oddly websearches have yielded no real insight as to how to fix it.

update: Commodore stuff for goodbye... (and one OT item...)

by zmerch＠30below.com

=-=-= Most of the commodore stuff has been claimed, but the claimant wasn't "as interested" in the following items; so they're still available (for a short time, this stuff's gotta go...) : =-=-= Shipping from 49783; have a "Pack -n- ship" place next door, so there is usually a surcharge to normal UPS/Fedex prices (being next door, we usually get a bit of a break, however). All of these items are "condition unknown" - they were given to me, and I've never had 'em hooked up. No warranties, and all that jazz. (1) MPS802 printer - in original box with original styrofoam; ready to ship (just needs to be taped up) - looks to be in really good shape, but that's just looks... (1) MPS802 printer - no box, no top cover. The stuff's gotta go ASAP, so unforch, it's first come, first served... =-=-=-=-=-=-=-=-=-=-=-=-=-= OT blurb: I have a PlayStation 1 available with some interesting goodies; $100 shipped; contact me off-list if interested. -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right???

One doesn't have to worry about handshake since the program can run at full speed.

I don't remember... help..

by rhudson＠cnonline.net

I am trying to remember the apollo systems I was administrating in about 1984 while I worked for CALMA. They were very large, slightly smaller than a 3 foot cube, They had very large monochrome displays (21") and ran an os known as appollo domian, which was very unix like. They keyboards all had touch pads. The systems were connected via the same type of coax used in cable tv. They were connected in a loop. One system had a open reel tape drive, one of the slide in reel types that threaded itself. There may have been a color version too.

Stuff available: PDP-8 desk, Masscomp

by e_cloud＠yahoo.com

I have to get rid of some of this bulky stuff that I'm not getting much use out of... I have a PDP8 desk (sunken area for console, rack under the left side) that I was using for my PC workstation but have since built another desk that holds more equipment, so this one is now surplus. The power controller that came with it is available depending on how much you want to offer. I never had the computer itself; I found this desk at ASU surplus several years ago. I found a picture of it on the 'net a while ago but have lost the link. I have a Masscomp of some kind. It's dusty now and I haven't tested it, but a friend unloaded it on me a couple years ago and told me it worked the last he knew; it has a hard drive and floppy, and a lot of serial ports. It is mounted in a rack about 4' high, which is half-empty. I have a lot of manuals and disks etc. for it. I was told this is an early real-time Unix system using the 68K processor. I live in Phoenix, AZ and you would need to pick these up. I'm open for offers of any kind on either of them. Please email e_cloud(a)yahoo.com; I will try to check the list but I'm subscribed in digest mode and will be more likely to notice if you email me directly. ===== . _______ Shawn T.

help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

The results of the last tests. I measured the contacts on the G7273: all ok. Next test. Conditions: console in slot 40, G7273 in slot 41, M9302 in last slot. slots 42 till last also have G7273's. Result: hung. I swapped (sorry Tony) the G7273 of slot 42 and slot 41. Again: hung. Last test. Moved G7273 from slot 41 back into slot 42 and put the RX211 in #41. The machine runs fine. PROMs on M9312, console, CPU regs, all are accessed without PAUSE going on. > OK, it appears there are 3 possibilities to check out : > > 1) The G7273 card is faulty and/or not making proper contact, > and is thus not actually completing the NPG chain. > > 2) The device _before_ this slot (possibly the arbiter > itself) can drive the input of the RX211 card, but can't drive the > terminator.

With the tests/swapping I established good starting points where to look. I agree it is time to pull out the "heavier" tools. This means more than just a quick glance at the schematics. I will post those results, but that might take a while ... tnx all, - Henk.

Motherlode or scrap ?

by lgwalker＠mts.net

Well I finally got back to the salvage/surplus place to get a list of the HP stuff they had and found they had another big room full of stuff they had removed from a large government installation. This was in the attic of a large building during one of the hottest days we've had up here and my sweat was dripping on my notepad so please excuse my attempts to decipher my notes. You must also realize that I'm a complete mini neophyte. The original HP stuff I saw : HP 12979A I/O expander HP 96MX System controller HP 7970B Tape Unit HP 1000 w/ cybernex 1100 term HP System 2748B There were also several HP 2624 A, B, and Standard K-Bs and some monitors or terminals on the skid. The big room was dominated by about 50-60 Sybernex workstations (which are similar to the Wyse ones so often tossed by thift stores), heavy duty monitor arm stands, and metal desks. But then the goodies. About 20 DEC VT420/320/220 terminals A box of LK402 keyboards (20-30 of them) An IBM 3278 terminal A DEC VAX SA482 rack w/4 populated banks About 10 Decwriter II's and III's A DEC VAX 6310 in rack 2 very impressive-looking 5' MagTape racks Honeywell CPUE 111 Morel DP S6/92 There were many other things. Honeywell equipment, large printers. etc. that I didn't write down. Do you think that the Gods are now demanding that I collect mini's, teasing me first with the Pro 350's I rescued from the town dump recently? And in the wilds of north central Manitoba.(Where in hell is that ?) "Winnipegosis sounds like a disease." Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

Tape Drive Questions

by palazzol＠comcast.net

Hello, I've spent some time over the past year or so reverse-engineering the Mattel Intellivision Keyboard Component. This was a prototype computer add-on for the Mattel Intellivision game system, which was test-marketed but never released. I'm basically done figuring almost everything out about it, and working on emulating it. You can read about it here: http://www.intellivisionlives.com/bluesky/hardware/keyboard_tech.ht ml The tape drives in these units were unusually sophisticated. They were essentially random-access 4-track cassette drives. Side A was read-only, and side B was read-write. Also, on each side, the left channel was audio and the right channel was digital data, directly recorded. This would allow for applications to Read/Write digital data and play/record audio simulataneously. They also has the ability to detect the tape leader via an optical sensor. The 2 questions I have are: 1) Does this drive sound like a drive from any other vintage computer system? 2) Anyone know who could tackle repairing such a thing? I've had no trouble fixing electrical problems, but tape drives are a whole different animal... I've basically examined 4 of these units and they all have mechanical problems. Emulating the system may prove to be the only way to ever see the software running. Thanks, Frank P.S. - If I make it to VCF 5.0, I'd like to do a talk about emulating old systems in general, and using this one as an example in particular. It's quite a beast.

A DPS-6/92 is a 32-bit member of the DPS-6 (formerly known as Level 6) family.. Ran GCOS mod 400 or mod 600, possibly the Ultimate OS as well (a Pick OS for DPS-6s).. Well I'm fairly sure its 32-bit, earlier DPS-6s were 16-bitters but I'm nearly certain that a 6/92 is a 32 bit.. I believe the maximum memory for it is 4 million words.. Fast fast machine, mid to late 1980's vintage.. What peripherals are wih it? Honeywell's line printers were mainly Dataproducts units, the terminals should be VIP7xxx family I believe, could possibly be branded as Bull, since Groupe Bull bought Honeywell's computer division after years of co-development.. Disk drives I believe are OEM'd CDC units, same with mag tape drives... I don't know if anyone else would, but I'd sure pay money for it and all the related bits.. Hope you've gained some info on it from my description..

IMPORTANT LIST CHANGES

by lists＠subatomix.com

This is your interim list admin speaking. Jay and I have been working together to bring about a major change for the better for the ClassicCmp mailing list system. It is important that you read this entire message. Ever since the two-list system was implemented earlier this year, cctalk and cctech have been somewhat separate communities. Posts from cctech were automagically forwarded to cctalk, but no posts from cctalk were forwarded to cctech. This could result in many on-topic conversations taking place in cctalk but never reaching cctech, which greatly detracted from cctech's value. This is no longer the case. As of a few minutes ago, all posts to cctalk will be forwarded to cctech. Each one will be subject to moderation, where I will weed out any off-topic posts. All posts to cctech are still forwarded to cctalk as they have been. In effect, the list has become a single unified ClassicCmp again, but now with two interfaces. All on-topic posts to either list will be sent to both lists. Off-topic posts will only be sent to cctalk. Subscribers to cctech won't be left out of the conversation. In a related change, posts to cctech will no longer have the "[CCTECH]" string prepended to their subject headers. This change may slightly adversely affect some subscribers. If you are subscribed to both cctalk and cctech, you will need to either unsubscribe >from one of them or set the "no-mail" option on one of them. If you do not do this, you will receive two copies of each on-topic message. If you do stay subscribed to both lists, please exercise extreme caution when posting. Your messages will forward between the two lists without generally being subjected to moderator approval. Do not post off-topic messages when your subscription is configured in this way. Thanks, and enjoy the new ClassicCmp! Look for a new web site and FAQ soon! -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic. Please send off-list mail to roach jay ess ess at wasp subatomix beetle dot com. You may need to remove some bugs first.

You haven't mentioned what kind of backplane it has (Q/Q vs. Q/CD), whether it has 22-bit (I suspect just 18-bit) and how many slots. These will all affect what the suggestions. Going with what you have, I might suggest upping the power from an 11/2 to an 11/73 (KDJ11-A), which takes up no more room in the backplane. >First, however, I'm sure I need DEC boot roms for it, or some other way >to get boot code into it. Does anyone happen to have some laying around >they could maybe send me an image of? Also, I'm on the lookout for a >RLV12 and berg cable to connect to the RL02 I have sitting around here.. I would suggest an MXV11-B, which gives you two serial lines, memory and boot code in one dual-high board. Beyond that, the DEC MSCP board is probably an RQDX(3?) and is not ESDI (I don't think there was an ESDI board made by DEC... all the ones I got while inside DEC were made by Andromeda -- the ESDC board).

Commodore stuff for goodbye... (and one OT item...)

by zmerch＠30below.com

Have some commodore stuff to get rid of; most needs to be boxed; will see what I can do to alleviate cost of boxing... Shipping from 49783; have a "Pack -n- ship" place next door, so there is usually a surcharge to normal UPS/Fedex prices (being next door, we usually get a bit of a break, however). All of these items are "condition unknown" - they were given to me, and I've never had 'em hooked up. No warranties, and all that jazz. (1) MPS802 printer - in original box with original styrofoam; ready to ship (just needs to be taped up) - looks to be in really good shape, but that's just looks... (1) MPS802 printer - no box, no top cover. (1) Model 1351 mouse (2) old-style C=64s; 1 looks complete, the 2nd missing keys from the keyboard. (1) new-style C=64 (similar case to the C=128) - looks complete, has a "document support stand" attached just above the function keys. (3) Model 1541 floppy drives - one is in the original box, and has a garage sale sticker that says "doesn't work, $1.00" - the other two are bare; obviously; condition unknown. (1) commie (clone) drive of unknown specific origin: sole marking on the front says "excelerator plus"; back says on small sticker: "Oceanic Electronics Corp. / FCC ID: GLB3390C-118 / Golden Image / Made in Taiwan / [FCC blurb]" - serial # 1149152. Your guess is better than mine... :-) (2) manuals - one listed as C64 user's manual, one listed as C64 user's guide; printed in prolly 1984 & 1983 respectively. All for cost of shipping, and boxing if I can't find the materials... If local pickup (Sault Ste. Marie, Michigan; take I-75 north until everyone says "eh?" ;-) it's free, but I'm not holding my breath... The stuff's gotta go ASAP, so unforch, it's first come, first served... =-=-=-=-=-=-=-=-=-=-=-=-=-= OT blurb: I have a PlayStation 1 available with some interesting goodies; $100 shipped; contact me off-list if interested. -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

This makes it fairly difficult to see them. On the 11/70 backplane I have, the NPR grant is also wired before all other wires. That is what makes me nervous when I start thinking about cutting a wire for a DMA device. A DD11-DK 9 slot gen purpose backplane is a lot easier when it comes to accessing the NPR wires. I agree that *looking* with a good light source is not too difficult. - Henk.

Quadram Quadboard

by pat＠purdueriots.com

Hi all, I'm trying to get two of these to work in a single PC XT so I can max out the memory. I have figure out the 'left' set of dip switches sets the memory starting address, but need to determine the functions on the right set of switches so I can modify the printer port I/O address, serial port address, and hopefully the size of memory that it thinks is on the board. Any help would be appreciated. Thanks. -- Pat

VAX11/780 memory / UNIBUS interaction???

But none of the M8375s changed the problem. When I replaced the M8376 it was even worse: ESKAR-V2.0 3D,3E, CPU TR = 00000010 DW780 AT TR 00000003 RH780 AT TR 00000008 RH780 AT TR 00000009 NO MEMORY CNTRLLRS DEP MS780EH ADDR IN RC0, TYPE LO ?ERROR: 11FA TEST: 0180 SUBTEST: 0001 TRACE: 00, FAILING MODULES: M8376, this time it didn't even go beyond test 3F. So, I put the old M8376 back. And tried to swap the lower and upper M8375s to see if I'd get the problem on the other end. After all, I assume that the message: 54, ?ERROR: 10B8 TEST: 01FF SUBTEST: 0001 DATA: 20002000 20002008 FFFFFFFF FFFFFF00 FFFFFFFF FFFFFFFF 00000000 00000000 TRACE: 00, FAILING MODULES: M8375-L, M8376, means that the M8375-L with "L" for LOWER is causeing the problem. So, I expected M8375-U to be blamed next. But not so. I always get M8375-L, M8376 error. However, what's really strange and the focus of my question is that the outcome depends on whether or not the UNIBUS cabinet is powered on or off. If I have the UNIBUS powered on I get that above error. However, when I have the UNIBUS off, I get this: 54, ?TIMEOUT IN TEST 01FF UPC= 1241 That is, TEST 01FF always fails, but when UNIBUS is off it just times out, when UNIBUS is on we get that failing modules error. Isn't there a way to decouple the UNIBUS issue from the memory subsystem diagnostics? I sort of hope that the boards really aren't broken but some other wires are crossed? I appreciate any advice of you VAX veterans out there! thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

cctalk digest, Vol 1 #83 - 27 msgs

by gstreet＠indy.net

Hello Dave and Tom, This is my first response to cctalk, so I don't know if it'll "take" or not. Just a couple of comments: I've also got a CRT with crack outer glass. I don't know what type of gel they used to bond the CRT to the outer protective glass, but Tom's suggestion seem plausible--depends on whether or not the "gel" is soluble by acetone and also whether or not the gel is destroyed in the process. Even with optic cement, would it be able to fill large voids left by dissolved gel? I don't have any idea--just asking. If any void remains, it's going to appear as a large "bubble" in your viewing area... Also, I tend to think that gel and protective glass may only be for extra protection. In the "old days" I used to see lots of CRT's that had no protective glass bonded to the front. If you broke the front, you broke the CRT itself. I seem to recall having broken a few of these things with pellet guns when I was much younger and never getting the hoped-for catastrophic implosion (my 6th grade science teacher warned us of when he shot an old TV CRT with a .22 and created a massive and dangerous implosion. Could it be that older and larger tubes were more dangerous for some reason??). I don't know. Maybe the glass is thicker these days. I still respect CRT's, not only for high voltage, but also for possible imposion dangers. Good luck on a solution. Regards, Robert Greenstreet gstreet(a)indy.net ----------------------------------------------------- Message: 20 Date: Mon, 15 Jul 2002 09:16:45 -0500 To: cctalk(a)classiccmp.org From: Tom Uban <uban(a)ubanproductions.com> Subject: Re: CRT problem Reply-To: cctalk(a)classiccmp.org Hi Dave, I have a similar problem with a couple of CRTs from my Imlac graphics machine. After doing some research, the I did locate a company which would rebuild the CRT for something like $700, with no guarantee that they would not destroy the tube. They also had expensive replacement tubes, which were not the correct phosphor. Another solution, which I haven't tried yet is to remove the CRT from it's electronics and soak the face in a bath of acetone for an extended period of time (or until the secondary lens is separated from the tube. Once separated, clean and reattach using optic cement. This was suggested by a friend who repairs large antique camera lenses. I'm not sure if acetone will dissolve the cement which holds the lens to the tube, so a pre-test may be a good idea. Some people have indicated a fear of removing the lens from the tube face thinking that the tube may well implode without it. I do not think that will be the case, but I suppose that it is possible. I believe that the lens is simply added protect from day to day use for the face of the tube and is not inherently required to maintain the strength of the tube against the vacuum inside. In any case, as always, great care should be taken to protect you, your eyes, etc. when handling CRTs, as they do carry the risk of implosion. --tom At 10:18 PM 7/15/2002 +1200, you wrote: >I have a 10 or12 inch green screen CRT off an HP 9845B I need to clean up. . >It has been stored in a damp environment and the silicon rubber 'bonding' >the protective glass screen to the front of the CRT proper has developed >large mould spots in side itself for an inch or two around the outside edge >of the screen.

help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

OK, the continuing story goes on to its conclusion. It looks I have been bit by the RX11 experiment. Some evenings ago I swapped the RX11 for an RX211 card, but I did not have the time to do some tests after the swap. Wish I did ... But first some replies to suggestions made. With the RX211 in slot 41, the DL11 in slot #40 and a M9302 + I can access the diags at 765000 on the M9312 successful + I can access the PROM at 773000 on the M9312 + access to CPU registers and MMR0-1-2 (777572 /4 /6) are all OK. + read/write the DL11 registers also OK! ??? I do not have a problem ??? Going back through my notes I see that the swap RX11 -> RX211 was the last action. So, back to the previous state: RX211 out, RX11 in. Guess what. The hung condition is back. The RX11 is a programmed I/O device. I knew that. But thanks to Tony's e-mail that older cards *do not* wire CA1 to CB1 if they do not use DMA, I checked the RX11. CA1 is not connected to CB1. That explains the hung. > It's OK to solder a wire (carefully) between the 'inside' > end of these fingers to make a DL11 (or whatever) that will > work in any slot. Some of my cards have been modified in > this way by the previous owner. I don't do that -- I fit the > wire-wrap jumper on the back of the backplane as DEC intended Again, Tony has the same thoughts I had yesterday. I did consider soldering a wire to the first 2 pins on the component side of the RX11 card. I did not. To make sure, I put the RX211 back in: all OK again. I made a note that slot 41 has the NPR wire on the backplane cut and that slot 40 has the NPR wired on the backplane. By experiment I will check the NPR wire of the other UNIBUS slots. You know why once you have seen the backplane of an 11/70. However ... (I will check this again) RX11 in slot 41 --> hung and we know why. RX211 in slot 41 --> all OK and we know why. G7273 double grant in slot 41 --> THE HUNG IS BACK! Huh?? Although the G7273 card puzzles me, I want to thank everybody for their contribution to solve this problem. I learned a lot from it. Also learned what that "SWR" column means in the M9312 manual. I had it right under my nose Johnny! It is even on my website in the tree "PDP-11/34A/CPU info/options/bootstrap". On that page all the ROM tables are listed including links. http://home.hetnet.nl/~tshaj kind regards, - Henk.
