IIRC the Floppy on an Altos 580 is DSQD. I had one that had the CMI hard drive replaced with a Seagate ST225. So I know they will take similar configured Hard Drives. I think they will take 10, 15 and 20 Meg HDs. Paxton Astoria, Oregon

DSQD Drives (Was: RE: Diags/Boot image for Altos 580)

by ajp166＠bellatlantic.net

The best way to write QD media is to use a TEACFD55GFV or FD55F as both work. Then the actual media is the BROWN or 360k stuff that has been bulk erased. The resulting disks will be reliable aswsuming the drive hasn't been munged or the formating incorrect. A PC FDC can drive these drives and will/can format them. You will need a utility program that does disk reading and formatting with CP/M formats. FYI: the TEAC drives are my favorite for any 80track format either single or double sided. I use them as substition for RX50s as well. Allison

A lot of the later CPM and early MS-DOS (but not necessarily IBM compatible) machines used them. For example, they were popular additons to the Sanyo 55xs.

Yes, MS-DOS can handle them. There's a DOS device driver that I can't think of the name of but it will let you specify the number of sides, tracks and sectors.

IBM System/36 SSP on 5.25"

by ceby2＠csc.com

... back again with my periodic thread on System/36 IBM mini-computers... When I last left you... we were all bitching about SPAM. This week... we're bitching about SPAM?! The 5362 is in good health, and I've started to fool around with actually using it. As soon as I can find the LAN interface for it I'll integrate into the rest of my motteley managerie on line (the better to play with over VPN while travelling). To get to this point I hacked the security file, deliberately corrupted the VTOC and re-installed the SSP. I found scanning the disk sector by sector for appropriate files an... experience. Worked though. The 5360 was successfully moved from a printers workshop into it's temporary storage unit. My back is recovering. The U-Haul van started mysteriously burning oil. Co-incidence? You be the judge. Can't say as I've powered her up -- or even done a proper inventory of part numbers. I'm sure that's all something to look forward to, or at least it will be next time I can spare the day to drive down to Hartford. The 5363 arrived while I was away on client site. I get power and error messages on it right now. Still investigating.... Steve Robertson gets gold stars for his assist along the way. I've acquired his set of System/36 documentation. Slowly it makes it's way across my scanner. The prospect of buying a page feeder gets more appealing every page. Which leads me to the subject line of this e-mail: I have the SSP set on 8" disk, but that's not only a different format but a different version than what's supposed to be used on the late System/36 like a 5363. The 5363 continued to add version numbers to the SSP in a 5.25" version. The 8" stopped around V5. I'd like to bring the 5363 around, but I could use some additional tools to do it. Anyone out there holding onto a 5.25" SSP set? Warmest, SPAM-free regards, Colin Eby

Speaking as someone who did this many years ago (duplicated MV DIAG TK50) it is not a simple dd job. You have to copy the entire structure of the tape, which is something like <tape header> [<file header> <file contents> <file trailer>] <tape trailer> Repeat section between [ ] as many times as there are files on the tape. Each header and trailer block is (I think) 80 bytes, and there are FileMarks at the end of each and every header, trailer, and contents. carl

Dilog DQ-634?

by djenner＠earthlink.net

Anyone know what a Dilog DQ-634 does? I haven't found any information on the Net except for a couple of places that have them for sale. It obviously interfaces two MFM drives, due to the connectors on it. What DEC drives does it emulate? Is it a never version of the DQ-614, which emulates RL01/RL02s? Thanks, Dave -- David C.

Switching PSU Theory of Operation / Repair Tips

by reversebias＠talk21.com

Re Where does the 600v come from? The SMPSU in question is probably of the 'Flyback' or of the 'Forward Converter' type. In either case the converter O/P Tx primary winding is connected between the +300vdc rail and the collector of the switching transistor. The emitter of the switching transistor is connected by a small resistor to the 0v (-tve) rail. During the conducting period of the switching transistor (lets call it TR4 - it often is) the potential across TR4 is very low, a few volts. Hence virtually all of the 300vdc appears across the primary winding of the O/P converter Tx (lets call it Tx1). The collector of TR4 is therefore at -300vdc. When TR4 is driven into its 'off' period Lenz's Law causes the primary inductance of Tx1 to try to maintain the primary current. The resultant induced emf (due to collapse of primary flux) now produces a +tve potential at the Tr4 collector and a -tve potential at the +dc rail end of Tx1 primary. Hence the Tr4 collector is now 300vdc positive to the +300vdc rail. Therefore the collector of Tr4 is now 600v +tve to the 0v (-tve) rail ofv the PSU. Don't touch its Heatsink while the PSU is switched on. Also allow 4 or 5 mins for the voltages to bleed down after switching the PSU off before touching internal components. (It should give this warning on its nameplate) Hope this is clear and useful - it is 3.30am in the morning here in UK. Regards John Salmon Q&R Engineer

I don't think they are GCR but someone more knowledgeable than I will have to answer that. My understanding is that they are the same as a 360 drive with a head that is half the width so they can deal with 80 tracks instead of 40. > > What other machines might carry these drives, can I > hook one up to a standard PC controller in a box > running DOS, and then duplicate the disks? > > The answer to this is yes. For many years I kept an IBM PC (8088) clone with DSDD, DSQD drives and my EPROM programmer. IIRC I used the 3 1/2 inch 720K disk driver for the DSQD and it worked for my purposes of making disks for various systems. I used Media Master (sorry Fred) and PCDOS 3.3. Many systems of the MPM era used DSQDs, some single user computers like the Kaypro 4, too. The Intel 310s used DSQDs also. This is where most of mine came from. I still have a few 310s and DSQDs.

Diags/Boot image for Altos 580

by drdidlittl＠yahoo.com

Bleh. MDR's mailserver is down, and I can't get in to fix it till Monday. Well, the Altos 580 ended up costing me $5 and "a future favor". Tyler couldn't find any of the floppy disks for it. It looks fine inside, except that the case fan was unplugged from the PSU. After finding the power header & plugging it in, I understand that. It does speak VT100, on RS232 port "JC" (Thanks, Andreas!) and boots to "Boot Monitor v7.03". Passes system tests, and attempts to boot from the hard drive. The activity light on the floppy drive comes on and stays on. I don't think the hard drive, a CMI CM-5619, is powering up at all. If it is it's incredibly quiet.... Anyway, I don't have any way to test the system. I did find an archive of MP/M II for it, but the zip file isn't in any image format. Does anyone have the install disks, and the Diagnostics/utilities disk, or disk images? And a way to create the disks on a Linux box? They are DD/DS floppies, right? Does this thing care what MFM disk it has? More junkyard fun.... Doc __________________________________________________ Do You Yahoo!? Yahoo!

HP 2100/21MX emulator

by jwest＠classiccmp.org

My work on the emulator for the HP2100 and 21MX computer systems (and all applicable peripherals and interface cards) is reaching a point soon where I would like to solicit someone to help me with compilation testing on various unix platforms. I am doing the development and testing on FreeBSD, so of course I know it will work there. I am hoping that some list members can provide me with remote access to different unix platforms so I can make sure that it will compile correctly. I would like to make sure it will work on Sun, Linux, and HP-UX as well. I have access to quite a few HP-UX machines, but not Linux or Sun. Being a staunch FreeBSD bigot, I have no desire to install Linux myself. The emulator depends heavily on the implementation of fork(), execl(), and SYSV IPC mechanisms such as message queues. I have heard that there are some differences in the implementation of fork() on Linux for example. At the outset I wanted very badly to allow it to work on DOS/Windows platforms, but later in the design phase it became apparent for a variety of reasons that this simply isn't feasible, unless someone knows of a way to use SYSV IPC stuff there. If anyone can allow me remote access to these type of machines, please contact me offlist. Regards, Jay West

HP 715 and IBM 6091 monitor

Hello, I have recently got an IBM 6091-19 monitor and figured I could use it with my HP 715/80 workstation but it doesn't work. Setting different video modes in the HP's boot monitor does not do very much either. The best I get is a partly readable but vertically diverted (sorry, I don't know how to describe this properly) picture. Looks like it cannot sync. Do you have any suggestions?

list problem fixed

by jwest＠classiccmp.org

The problem with the mail servers has been found and fixed. Turns out it wasn't due to the changes I had made. One of the open relay databases that we use for checking smtp servers that we will converse with is currently out of service it seems (mail-abuse.org). As a result, all the "dns"-style lookups our mail server would do to them to check for open relays would timeout. I removed the check for that service temporarily until it's disposition is known. Fear not - we have other services we check for open relay as well and they are still in effect. If there are any further problems with the list, please email me directly. And now, finally, perhaps sleeeeep Regards, Jay West

list problems

by jwest＠classiccmp.org

What timing *sigh* I just noticed this morning that there is a rather severe problem with both our primary and secondary mail servers for the classiccmp.org domain. I must admit with much chagrin that it appears to be one of a set of changes that I made a week or two ago, but only manifested itself this morning. I am not sure of exactly which change caused the problem, but I have been working on it all day and will continue to do so till the problem is fixed. Symptoms - inbound connections from remote mail servers experience a long delay after the connection is made before sendmail acknowledges the connection. Most of the time the mail goes through, but the long pause bothers me. Other times the remote mail server times out, and retries later, but gets through. As a result, it appears that mail is going through but is significantly delayed. The error message is the typical "timeout waiting for..... during client greeting". No, the problem is definitely not reverse DNS (ident) or low level network related - the typical causes for that problem. I will post to the list once the problem is resolved, unless I choose to finally get some sleep. Jay

Diags/Boot image for Altos 580

by dhquebbeman＠theestopinalgroup.com

> Does anyone have the install disks, and the Diagnostics/utilities > disk, or disk images? And a way to create the disks on a Linux box? > They are DD/DS floppies, right? My former employer ended up giving his to a local guy who fixes radios, PCs, controllers, hell anything (he and I did an embedded systems project once); I just got off the phone, he remebers the system, knows its "there somewhere", as I also recall seeing it there as well as the disks in a dark maroon Dysan disk box. He's a bit busy at the moment, but promised to start a search for the disks when he can. > Does this thing care what MFM disk it has? The CMI hard drive was a total POS. I've got one >from a Zenith Z-150 that works until these *huge* power resistors on the interface board heat up too hot, then it stops working. I'm not sure whether they're part of the drive motor circuitry or the head motor assembly, but ISTR suspecting the latter. The drive is available free, for cost of shipping... if you're even vaguely interested in a failing hard drive. However, you might be able to combine parts from them long enough to use one while you transition to a more reliable old drive (assuming of course Chris finds the software). -dq

What Computer is This and Who is This Guy?

by d_l_mcd＠hotmail.com

Here's a picture from 1966 of an IBM computer at the IBM computing center on Manhattan (New York City, New York USA). The text for the photo says that the computer is being used to make a payroll calculation. Visible are 4 big-fridge-sized reel-reel tape devices, the console with operator seated at it, and some other things in the background. What's the computer model? Does anybody know who this guy (operator) is/was? Just a neat photo.

I have a PDP-11/34 programmer's console, what should I do with it?

by gunther＠aurora.regenstrief.org

Hi, I have a PDP-11/34 programmer's console but no PDP-11/34, what should I do with it? My options are: 1) get a PDP-11/34 2) trade it with something I need more, like a PDP-8/A power regulator(G8018) and limited function panel so that I can build my third PDP-8/A :-) PDP-11s were never really my plan to collect, but I wouldn't mind having one specimen of 2.9 BSD running. So, may be I should get an 11/34? cheers, -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

eBay Purchase

by jhfine＠idirect.com

Help - What am I doing wrong? I sent the following response (SEE AFTER DOUBLE LINES of ======) to a previous e-mail in respect of auction: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=2006598832 This time he did not even reply. Am I being overly cautious is making sure that the correct customs documents are used? Previously, we have agreed on the Shipping, Handling and insurance to be $ 24.45 and that he would ship to Canada, but for some reason which I can't understand, he seems to think that using the GREEN CN-22 or a COMMERCIAL INVOICE is not a reasonable requirement. While the shipping seems a bit high, I did not quibble and agreed to pay what was asked. His Positive feedback seems satisfactory, so what could the problem be? His name and address are: Bobert1959(a)aol.com Bob Bruns 6334 Alta Oaks Dr Garland, TX 75043 However, this information seems to not be traceable. Is there anyone at eBay whom I can contact? Any other suggestions? Sincerely yours, Jerome Fine MY RESPONSE TO HIS E-MAIL FOLLOWS: Bob Burns does not reply. ================================================ ================================================ >Bobert1959(a)aol.com wrote: > the terms of the auction are decided prior to the end. No other terms will be > accpeted. The shipping amount has agreed on. If for some reason the auction > terms are unacceptable. I will sell the item to the next highest bidder. Jerome Fine replies: If everything in this e-mail is satisfactory, please respond with "Confirmed" as the first word in the body of your reply. Also, please add if you wish me to prepare the COMMERCIAL INVOICE for you. Your reply seems to suggest that by requesting that you comply with shipping requirements at port of entry into Canada (and probably any country - although I am not familiar with regulations elsewhere), I am changing the terms of the auction. I hope that this reply will help you to understand that the terms of the auction are not part of the requirements for shipping the drive and that I have nothing to do with these requirements. In addition, if you read my last e-mail carefully, all that you have been asked to do is to correctly provide the value of the item to the customs officials in Canada. When a package is sent via USPS, then I understand that a GREEN CN-22 form is used. However, since I am not aware of exactly how USPS handles air shipments, I may be incorrect. In that case, customs officials in Canada may require a "Commercial Invoice" which is filled out (based on my limited understanding) as a simple paper with: =================================== COMMERCIAL INVOICE Your Name, Address and phone contact number My Name, Address and phone contact number Value of the Drive: $ US 11.50 =================================== It is that simple. I don't set the requirements. Here is my part if you need to send a Commercial Invoice: Fine Services & Co. Ltd. PST Exempt - 1531 2240 2 Inglis Gate Willowdale, Ontario, Canada M2R 3G3 Attention: Jerome Fine (416) 667-8233 Please note that ALL FIVE lines are essential for the complete address and contact phone number. In addition, ALL FIVE lines are essential on the outside of the box and on any shipping document. I will include this information on a sheet of paper which I will include with the money order and the auction Item Number 2006598832. All you will need to do if a Commercial Invoice is required is to add your contact phone number to your name and address plus the actual value of the eBay auction. Again, I don't set the shipping arrangements - they are imposed by Canadian Customs at the port of entry. I you wish, I can prepare the COMMERCIAL INVOICE for you - all you will need to do is add your contact phone number to the paper. I anticipate that you don't wish to violate the requirements that Customs Canada imposes. I certainly don't think that a COMMERCIAL INVOICE is a difficult requirement since it takes less than a minute to fill out. All of our e-mails have certainly taken much longer. Certainly I have never encountered anyone who has ever refused to provide a COMMERCIAL INVOICE to Canadian Customs since all of the information is normally available in any case, just not consolidated onto the form which they insist on - although I agree it is a pain in the posterior if you ask my opinion. Sincerely yours, Jerome Fine

List Management - RESPONSE and how to question

by Innfogra＠aol.com

I, too, appreciate the work Jay has done on the list. I use this list as an example of a large well managed community. Even though there has been a slight increase of Spam recently it is way, way, way below any other list. We generate more Spam about the Spam than the originators. I am not in favor of closing the list just like I am not in favor of closing the community. Some times moderation is necessary but in IMHO less is best. I believe in self moderation, something we seem to be falling down on lately. If we do not reply to or about the Spam it will be hardly noticeable. And here I am adding to it. I would rather learn about how to attack Spam at it's source. I am learning how to decipher the mail headers. I need to figure out how to automate complaint letters. From what I have seen the direct complaint to the service provider works best. Links to any tutorials would be appreciated, as would recommendations on SW. Paxton Astoria, OR PS From what I have seen most of the Spam the list has gotten is very international in it's source and not traceable back to a single source. The FBI would like copies of the Nigerian Scam emails. They are starting to take it more seriously.

List Management - RESPONSE

by mcguire＠neurotica.com

I feel the need to chime in with some support for Jay. This is a high-traffic list with a lot of recipients, which surely takes a nontrivial amount of bandwidth and system resources to host...people shouldn't lose sight of that fact. I run a couple of fairly large mailing lists myself; something like this isn't a "set it and forget it" thing...Spam is the least of the problems, most of the time. People with crappy network connections whose mail gets backed up and queued, Windows programs that screw up everything in sight when moving mail around, twenty-line messages turning into 50Kbytes due to rampant Microsoft HTMLization bogging down the mail server, etc etc etc. It's a pain in the ass, and it takes a certain amount of babysitting to keep things running smoothly. Jay does a fine job. He may not have started this list, but he runs it now...and that counts for a lot. I hate spam as much as anyone. Actually, I hate spam a lot MORE than most for various reasons. But guess what...My mailer has a "delete" function, and I actually know how to use it! Wow, what a concept. I know, I know..."but spam slows down my net connection!" If your net connection sucks so badly that a little (or a lot) of spam bogs it down, then get something faster. There's no real excuse in this day and age. Spam blows dog, there's no question about it...but it's a fact of life on the internet today. Everyone should fight it whenever and wherever they can, but you WILL get spam if you have an email address. The sooner people learn to deal with that, the happier everyone will be. Further...there are lots of off-topic conversations on this mailing list. I take part in many of them, so I'm as guilty as anyone. But you know what? Humans are social animals, and this list is a social thing. Many of you are my friends. If there's an off-topic discussion here that you don't want to take part in, well, use that magical "delete" key...Every mailer has one. In other words...if anyone here has a life that's so utterly perfect that spam and off-topic discussions can offset the friendship, comeradery, education, and other classiccmp benefits, I'll swap lives with you any day of the week. Sheesh. -Dave -- Dave McGuire "Watch those lateral G's man, St. Petersburg, FL I've got sandwiches in my lap!" -Sridhar

OT: Memory issues

by Mzthompson＠aol.com

I say OT because some of this applies to newer machines, but I thought it might me worth sharing. I was in a tinkering mood yesterday. I had recently pulled the 256 mb (three dinky DIMMS) from a Pentium II and put in two 256 mb sticks. My motherboard docs state a max of 512 mb, but now I got a spare memory socket and could not resist. I stuck another 32 mb in and fired it up. The BIOS self test ran OK, and it booted to DOS find. But when I brought Microslop Windoze 95, I learned the true meaning of Windoze. You could click on the start button, take a drink of coffee, light up a smoke, and maybe, just maybe, the start menu would appear by the time you did that. A whole new meaning to the word slow. Needless to say, I pulled the 32 mb. Windoze returned to its 'normal' speed. Not content to stop there, I decided to up the size of the ramdisk from 16 mb to 32 mb. Since I boot to the DOS prompt, it was easy to catch the error stating invalid ramdisk parameter. So I took it back to 16 mb and starting incrementing it. I got all the way to 30 mb with no problems, or so I thought. I had only booted to DOS, and not brought up Win95 during the time. With a 30 mb ramdisk I brought it up. My display settings were changed and the display adapter was complaining. I returned the ramdisk to 16 mb and all returned to normal. I found nothing on a specific limit on a ramdisk in any docs I looked at. I have used a ramdisk since my XT days. Now it is almost like they don't want us to know about it. Any thoughts? ---------------------------------------- I also have been trying to add some memory to an old Gateway 486/33 machine I use for utility things. It already has 16 mb. I've tried several combinations of SIMMS all meeting GW requirements (36 bit parity 70 ns). It comes down to no matter what combination I put in, nor how I set the memory dip switches, it won't recognize anything beyond 16 mb. I have the manual of this beast, and it clearly states it is expandable to 64 mb. ---------------------------------------- And finally, I was confused by the recent posting on the DEC 3000/300. The reason was that someone handed me a bag of DEC SIMMS some time back and I thought they were for a 3000 but the descriptions in the recent posting dod not jive with what I had. The ones I have are 100 pin, 10 chip, 70ns and are a 4 mb module with room for another 4 mb on the back. It would seem that mine are for the 3000/400 and maybe higher. Mike
