I have a really compact "PDP-11/23S" chassis that has an 18-bit Q-Bus backplane (4xQuad) in it. Although the circuitry for the Q-Bus is on traces of a PC card, there are also wirewrap pins extending out from the backplane. Am I naive to assume that I can convert this to a 22-bit Q-Bus by wirewrapping four or so lines? Any pointers on how to do this or on technique? Thanks, Dave

PDP-11/34a - RL02 Help

by jpl15＠netcom.com

Hello List: I have some interlinked questions for the Assembled Gurus: I am trying to understand device adressing in the system as a whole.. is there a good 'base/vector addr for dummies' document I could be pointed at? I have looked (sunsite, etc) and I'm still missing something. I *did* find out how to find the backplane jumper to be removed when installing the RL11... after I discovered it, I notice some kind soul put a red sleeve on the CA1 pin on each of the slots.... Am I correct to assume that RL02s and RK05s can coexist and co-operate in the same system? I am trying to construct a 'fully loaded' PDP11 system, and I want to have the entire range of peripherals available, so that I can perform media and format conversion, as well as have fun running the thing. Will one system support the RX02, 9trk, RL02, RK05, DECTAPE, Paper Tape, consoles and a few terminals, and maybe an Ethernet adapter? I realize this will take a one or two expansion chassis... but am I getting overly ambitious for one CPU? Should there be, maybe, two closely-coupled '11s sharing the load? Eventually I am aiming for a VAX 11/750. Would it be 'better' to wait and use it's resources, whatever they might be? I want to spend a little less time maintaining and a little more time computing... and I'm dying to run some of the DECUS stuff on my Machine. Thanks So Much (in advance) Cheers John

New toys :)

by pjoules＠joules.enterprise-plc.com

I have just colleected a PDP-11/40 which is said to be working apart from the fact that the PSU has been removed. If I can find a PSU in the future then this will be my first 'lights and switches' machine. I was also given 2 Apple ][ s - 1 ][e and 1 ][Eurostar There is a disk drive with them, but I see from the notice on the back of the drive that it is supposed to be connected to an interface card. As they have no cards in them I suppose I will have to wait until I can scrounge one. Regards Pete

11/04 free;

by jpl15＠netcom.com

Hiya List: In the process of consolidating/thinning down my out-of-control collection, I think I will place my 11/04 system up for adoption. It is: 11/04 w/operator's console 7266 CPU 8265 CPU MOSTEK memory bd, 8001-H-00, unk (8K?) Plessey mem bd marked 64K depop to 48K 7856 SLU/RTC 7846 RX11 Plessey DMA? (can't remove w/out getting behind rack.) ACT Quad serial I/O unit. Plessey disk controller set and backplane (in seperate BA11 which I'm keeping to use later..) RX01 dual 8" floppy (2 ea) CDC Cealus (Ceali?) top-loading drives, accept RL02 packs (and probably are the same as RL02s) Plessey badged. Battery back-up unit H775A A load of cables, mebbe spare boards, engineering printsets, etc. I am also retaining the DEC rack it's in. I have had this machine partially on the air... it boots into ODT at the console, but I've never tried to boot from the big drives or the floppy. (This machine was removed from service and stored until I bought it, so it *used* to all work... it's not a mongrel system.) THE DEAL: I'm in Southern California. (Malibu). I am looking for a formatter card to use a standard 9-trk drive in a PDP-11/34a system, as well as the inteface card(s) to hook up my big System Industries drive to the '34A. I will disassemble and deliver the above items within a reasonable weekend day's drive, in return for the two devices mentioned (or at LEAST the tape card.) [Other gear related to PDP storage or any MINC stuff will be considered, too..] If, in two or three weeks, there is no response, I will GIVE the 11/04 system to the person who, IMHO, wants it in the worst way, ie. whining, importuning, pleading, tantrums, etc. will be considered..... BUT! given that scenario, you must come and pick it up and cart it off. This is a good 'starter' machine for someone (hopefully) on the list who wants to get going in PDP-land. Note to the adventureous: the combined weight is about 500lb... shipping ain't an option....... Cheers John

Altair Attache??

Doug Yowza wrote: You lucky dog! You got this from the guy that was spamming usenet a while back about trading his Altair for an IMSAI, didn't you? He told me the Icom wasn't for sale when I asked him about it. Damn. Doug, First of all I apologize to everyone on the list for the wasted bandwidth caused by my screwed up posts. I use Hotmail to view the list because you guys are so prolific that it would load up my primary email folders. But Hotmail seems to have a problem with messing up my posts to the list as you can see. Oh well, since I only post to the list every three or four months maybe it will be tolerated. Anyway this was my reply to your message... My Attache is a different one from the one you made reference to. I too emailed that guy but he never replied to me. My guess is that he got a lot of response and got cold feet on the deal. He's most likely still sitting on it. A week ago I made contact with a former employee of an Altair dealer. When they closed the doors he put a bunch of the stuff in his attic. I struck up a deal and drove 1600 miles in three days to retrieve it all. The Attache was part of it. I worked for this one. The 800 mile straight through in one day trip just about did me in. I am getting too old for this.

Attache Altair 8800??

by altair8800＠hotmail.com

Several weeks ago I inquired about the existence of an "attache" version Altair. Several kind folks offered their input as to what this might be. I was asked to share any information about this unit if it became available to me. I have since acquired it and have uploaded some photos for anyone who might be interested. Here is the link... http://home.att.net/~rwood54741/50.jpg It was made by Pertec when they were still producing MITS branded systems. The case carries the name "Icom Attache". But the innards are all branded MITS. Even the keyboard. Electronically, it is an Altair 8800b with the addition of a MITS keyboard. It incorporates all the same MITS circuit cards and the same power supply board as the 8800b. For that reason it is essentially a keyboard Altair 8800. The serial number of this example is 153 which leads me to believe that a precious few were produced and it is probably extremely scarce. I obtained it from an individual who worked for an Altair dealership which was in busuness in 1977 and 78 and he verifies that only a few were sold. I have docs on it.

Weitek "Multibus Array Processor" board

by svs＠ropnet.ru

G'day, I've come across aforementioned ISA board and some accompanying software. This is really a two-board set, held together firmly with screws. It uses two adjacent 8-bit ISA slots. On the top board the biggest chip is Weitek WTL1066 - a "FP data path" (Floating Point? Field Programmable?). There are no external connectors. How I can test it? Will it work in Pentium-class motherboards? (It currently sits in a computer very much alike the original IBM AT). What can I use it for? Cracking RC5 would be cool :) -- Sergey Svishchev -- svs{at}ropnet{dot}ru

I got the SE to go. Now, I need to get the SCSI harddisk I have to work for it. It has a (limited) version of System 6.0.8, and I have a 200 meg SCSI external I plan on using. How do I get the Mac to initialize the SCSI disk? (I can worry about System 7 later...) Also, it has an 800k disk... Is there any way to cheat and make a PC produce these? Or will the Mac take 720k disks too? (I can make a Mac-formatted 720k disk with hfstools... But I can't format the SCSI disk with it - no SCSI controller in the PC.) -------

Apple III & Profile

by ds_spenc＠alcor.concordia.ca

Greetings, I finally got around to trying the Profile hard drive someone gave me, with my Apple III, but I can't get it to work. I haven't tried formatting, but I wan't to leave that as a 'last resort', in case there's something useful on the drive. I opened up the drive when I first got it, to see what's inside. The actual drive mechanism is a full-height 5.25" jobbie, and IIRC it's 5MB. I don't remember who the manufacturer was. I power up the drive first, and wait until the READY light stops blinking. I have no Apple III docs, I just 'guessed' that that was the proper procedure. I don't know if it is yet. I then boot up the III with the SOS 1.3 Utilities disk. I've used the configuration program to make .PROFILE active. The configuration file reports the following: item field value 1 - Device Name................ .PROFILE 2 - Device Type................ $D1 Block, Read, Write ( range 00..FF ) Formatter present; NonRemovable 3 - Device Subtype............. $02 ( range 00..FF ) 4 - Driver Status.............. ACTIVE 5 - Comment Apple /// SOS Profile Driver (C) Copyright 1981, Apple Computer Inc. 6 - Configuration Block data Slot Number................ 04 Unit Number................ $00 Manufacturer ID............ $0001 Apple Block Count................ $2600 (9728) Version ID................. 1.00 I can't edit the configuration block data, though. If I go down to item 6 and hit RETURN, I get to the "Edit Driver Configuration Block" screen, which looks like it should have at least 16 values on it. It only displays "[FF]" at location 00, though, and although it says I can use arrows to go to other values, the arrows don't do anything. If I go to the "Device handling commands" section from the main menu, and attempt to Verify .PROFILE, the READY light on the Profile blinks, there is a clicking noise, and the READY light goes out. The program reports ".profile - Volume not found". The READY light stays out for a while, blinks a few times, then comes back on and stays on. If I go to "List devices configured", it pauses when it gets to .PROFILE, and reports "(no directory)", and the drive behaves exactly as with Verify. It's possible the drive just needs to be formatted, but as I said, I don't want to do that until I'm sure there's nothing salvageable on it. I'm not even sure I've got the cabling right. I assumed it takes a straight-through 25-pin cable from the ProFile controller to the drive unit. No twists or turns along the way? Also, I've got two Profile controllers, one in slot 3 and one in slot 4. I coulfn't get it to work at all from the one in slot 3, simply because it seems to have been preconfigured to look at slot 4. Any helpful info will be appreciated. Hopefully I don't get frustrated and try formatting the unit before I get a reply. :) Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

RED ALERT! Mainframes Available - Vancouver BC!

Rails needed

Check your junk boxes! I am in need of a couple (up to 3 ) pairs of drive rails for a Dell server. The rails will be plastic and have the marking of "PN 25102" molded into them.

On the brink of bidding...IMSAI

by rcini＠email.msn.com

You know, I usually don't bid on anything on eBay unless: (1) it's a low-demand Commodore or Apple item that I want which is (2) less than $20. This time, it's different. I'm intrigued by the IMSAI 8080 listing. It hurts me to think about paying real $$$ for a 20-year-old machine. At $356 (the last bid that I saw today), it's only, what, $150 cheaper than it was when new? It reminds me of the $1500 Altair a few months ago. I don't have one...I want one...I'd give almost anything in my collection for a working one. I just don't want to get screwed by frenzied bidding. If I'm thinking about that kind of $$, I'd much rather see it go to someone that I know. So, if someone on this list would like to save me from myself, let me know.

Commodore Vic 20 power sup

I assumed this happened because the current was too low (high enough to drive the Vic, but not the Vic and the datasette). According to the 8-bit FAQ (in Mr. Dellett's post) this is probably correct -- the lowest-current one listed there uses 1.7 amps.

RED ALERT! Mainframes Available - Vancouver BC!

by mcquiggi＠sfu.ca

Hi All: I have just returned from the University of BC here in Vancouver. They called me to see if I was interested in purchasing two mainframes that went surplus as of June 30th, 1988. They are open to offers, and do not want much money for these. The machines can be described (basically) as follows: First, an IBM Mainframe, ES/3090 400-J, several hundred MB RAM, many GB of DASD (thats HD to us non-big iron folks), 1/4" tape drives, cartridge tape, consoles, 3270 and newer terminals, chiller (system is water cooled), power supply unit, media, etc. This system runs MVS, also MTS and was the main computer for a campus of 20-30,000 for a period of about ten years. The machine is circa 1986 and is available to anyone who wants it, and will take it away!! I'd suggest that two to four semi-trailers would do the job, depending upon how many peripherals one wishes to acquire. The current front runner on this machine is a local scrap dealer who is going to chop up and recycle the machine for its metal content. :-( I've contacted Paul Pierce, mainframe collector extraordinaire, but he is unable to take the machine due to space and time contraints. Any other takers? Also available: A Hitachi (apparently) mainframe system, model HS 7023, terminals, tape drives, racks, disk storage. This system was smaller (about the size of a large VAX 750/780 installation), was also in working order as of June 30th, and is available. It sort of looked like a mini to me but the computing centre staff refer to it as a mainframe. Offers, you pick up. If there's any interest then please email me and I will be able to provide you with further information, and put you in touch with the surplus folks that are handling the disposal.

Denver Finds -- still avail

by sinasohn＠crl.com

Hi guys! I'm telnetting into my old accound from a bookstore in Denver... Just wanted to let any locals know that there is an NEC APC (Advanced Personal Computer) available at the ARC thrift shop at 10000 E. Colfax in Aurora. It's an older machine, looks like a VT-100, with a monitor and 2 8" floppies in the main unit. Not sure how much (tag was torn.) Also there is a Franklin Ace 1000 and a Commodore PC-20 III. And an IBM DisplayWriter. So far, I haven't picked up much, but I did get a Mattel(?) Odyssey, to "TV (that is, two (2)) game consoles, and an Atari Pong game in the box. That's about it; I'm off for more sightseeing.

MAC ATTACK

--- Van Burnham wrote: One of my co-workers has given me a fantastic Mac Plus...I cleaned it up and she's looking just beautiful (even has a Gigamation Data Cell external hard drive...so sweet!), except that when I fired her up, I found out that the mouse (MO100) is totally dead...it only moves horizontally...I tried some minor surgery, but to no avail. Also the keyboard (MO110A) is in trouble as well, some keys are missing and some simply don't function. Would any of you happen to have any spare keyboards or mice that you would be able to sell/trade? I would be thrilled to get this system fully functional again... Any advice would be very much appreciated. --- end of quote --- I don't have any spares right now, but I was going to suggest checking Goodwill/Salvation Army stores -- I saw a Mac 128/512/Plus keyboard for sale at one of those not too long ago. Also, Sun Remarketing (www.sunrem.com, I think) sells all kinds of old Apple/Mac stuff, including small parts (like maybe key caps and keyswitches). I've replaced those keyswitches many times, and if you can solder two dots onto a flat circuitboard, it's not very difficult. Unlike today's single-piece membrane keyboards, all the keys on the older Mac keyboards are separate. Other companies to try: Preowned Electronics, Shreve Systems, and Nexcomp, all of which specialize in refurbished Mac systems and parts (www.preowned.com, www.shrevesystems.com, and www.nexcomp.com). Nexcomp lists a Mac Plus keyboard, no cable for $25 and a Mac Plus mouse for $19. The others may be cheaper. Hope that helps! -- MB

Monitors

by lwalker＠mail.interlog.com

Well this seems to be my time for monitors. I just picked up a Taxan Multi Vision 770 Plus for $1.00 and an Atari Hi-res SM124 for $5. Last week I got a NEC Multisync JC1401P3A and Compaq VGA mono curbside, and acquired a Mac+ adapter for an earlier find, a Radius 15RAM1 Full page Display. Both Multisyncs have analogue<> TTL and mono-color switches and the Taxan has an overscan switch as well as a bunch of other controls. My main monitors have been a Nec Multi 2A for most of my VGA machines and a Commodore 1802 for my 8bits, not to mention my trusty Atari monitors with the bloody 13 pin connectors. I feel innundated :^)) Unfortunately I know little about monitors. Is there a good source for info on older monitors on the net or a newsgroup FAQ ? Is there a definitive textbook ? I have one, "PC&PS/2 Video Systems" by Richard Wilton but it deals mainly with software programming issues. BTW there was also 6 DEC Rainbow A and A+ in the same thrift for $1 each. No K-B or Monitors. I debated it with myself but have a RB 100B and a spare 100A and I'm already at minimal space, so I passed. They also had 2 Epson Equity's which I know ziltch about. ciao larry lwalker(a)interlog.com

by roblwill＠usaor.net

I didn't think it was the first. I have a Tandy Model 600, from 1985, and I *had* a model 100. I think I also have the first (correct me if I'm wrong) laptop with a printer. The Wang LapTop Computer (WLTC). It weighs about 16-20 lb., not including the external SCSI 5.25" 360K floppy (there's no internal disk drive), which weighs at least an extra 15 lb.. These things were definitely NOT for the light traveler. I think the WLTC came out in '84 or '85 (not sure). Mine is date Dec. 24, '86. I think it runs on a PASCAL-based operating system, with an MS-DOS emulator. Mine is "fully loaded", with a 10 MB "Winchester Disk" (hard drive), 1 meg RAM (alot for then), a modem (not sure what speed. if any one knows, let me know), and an RS-232 serial port. The battery even holds a bit of a charge) I have another WLTC - w/ 10 MB Winchester Disk, 512k RAM, and the RS-232 serial port. If anyone is interested in it, make me an offer. All of the parts are good, but the power supply. There is a blown capacitor in it - easy fix. It also does not have an external AC-DC adapter. I'm currently using a Tyco racing pack on the one that works. I also don't have a battery, but can give plans to build one. Make me an offer + shipping. -- -Jason (roblwill(a)usaor.net) ICQ#-1730318 ---------- > From: Doug Yowza <yowza(a)yowza.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Vintage Computer Festival Announcement > Date: Tuesday, August 04, 1998 11:47 PM > > The T1100 was Toshiba's first laptop, not *the* first laptop.

Apple IIgs Rom 0 Available?

by SUPRDAVE＠aol.com

feeling mean, i decided to email the induhvidual with the $6500 gs system and feign interest. seems to be a nice setup, but not for the price. he can't prove ownership and doesnt even have the original boxes for the main items. maybe i'll think of a real valuable system that i could "trade" him for, or either just tell him he's dreaming. >8-) In a message dated 98-08-05 10:54:48 EDT, you write: << I seem to have attracted several similar offers of late. I don't know if something new has slipped into the water supply or they just don't really know. I try and tell them but most seem to think they can retire off their old computers. Maybe he'll come back around after he can't sell it. I wouldn't mind having a ROM 0 just to round out my IIgs collection but I don't want one THAT bad. >>

Shure it is a B500 - i could send Photos tomorrow (all at home) Different label and no joystick connectors at the backside.

My peronal guess is that on first sight Commo had planed a B500 and P500 series of computers, but later switched to the 500/600/700 scheme (and then again to B128/256 for the US and 6x0/7x0 for Germany) - and eventualy dropped the 500.

Hmm - The question is which Commodore unit sold their info.

Off-topic informational anti-spam anecdotal

by Philip.Belben＠powertech.co.uk

> '*' and '#' have no pulse analogues. However, in the states at least, the > equivalent to dialing a dial access code preceded by a star or pound is > generally achieved by rotary dialing '11' before the code (ie. *69 would > be 1169). Fortunately in the UK there are no requirements yet (afaik) for * and # on the public networks. On the private exchange at work, 11=*, 12=#, 13=** and 14=##, at the beginnings of numbers only, but I don't know whether it still works. BTW, in the UK # is _never_ called "pound". "Hash" is the most usual name, followed by "gate" and "hatch". "Pound" means a script L with a couple of horizontal bars through it :-) > As for trying to communicate with auto-attendants, you'll probably have to > add external buttons to your rotary phone to give you the capability of > dialing '*' and '#'. That's what I was afraid of. Although a neater hack still would be a modified dial that did 11 pulses for * and 12 for #. Mechanically possible, but I wouldn't want to try and modify the old dial. There is a blanked-off hole in most type 746 phones that can accommodate 1 or 2 buttons, and I was thinking of putting # and * there, but this is more usually used for a "recall" button. Incidentally, does anyone know why "timed break" recall buttons are replacing local earth ones? And how long is the break? > While a pulse-to-DTMF converter is a neat hack (and these sort of > converters were installed in some step-by-step exchanges in the US, at > least there were in my local exchange when we were step-by-step, but come > to think of it I don't know why, unless they were converting my pulse > dialed digits to DTMF so that some other adjunct piece of equipment such > as a Dialed Number Recorder could know what digits I was dialing, for > purposes of surveillance ;) it'd be easier to just buy a cheap DTMF phone. Sam, you should be ashamed of yourself. The object of the exercise was not to get a DTMF phone, but to get one with a _rotary dial_. I already have a DTMF phone, and I am interested in thes project _purely_ for hack value. Slightly less far off topic, does anyone know the reason for the divergence in layout between phone keypads and computer ones, i.e. 123 789 456 vs. 456 ? 789 123 0 0 Which came first? Philip.

Near disaster and questions on finds

by sinasohn＠ricochet.net

The other day I was mucking around in the room I store most (some, according to my girlfriend 8^) of my collection, and all of a sudden one of the shelves holding a bunch of Toshibas, collapsed. Luckily, I was there and was able to keep them from crashing to the floor, but still... Upon closer inspection, it looks like the shelf with (some of) the GRiD's is about ready to go as well. These are those metal shelves you get at Target for $8 on sale. So, I guess my question is, how to others store their collection? Keep in mind that I'm in San Francisco, and that Earthquakes are an issue. Thanks! Oh, and latest finds: another Panasonic Senior Partner (I really need the specs on these if ya got 'em!) and one of those HP ThinkJets which I'm actually gonna hook up to my Dad's computer (as soon as I figure out where all those printer cables I use to have are!) Most interesting was a Cable Demodulator. Yep, not a MOdulator/DEModulator (MODEM), but just a Demodulator. Apparently, TCI at one time sent out a free signal on the cable that could be read by anyone with a PC and one of these boxes. So, anyone know if they still do that, and what software one would need? I also picked up a Mobidem, sans cable, of course, which appears to be a radio modem made by Ericsson. If anyone has any info on this.... Last but not least, a Datasonix Pereos tape drive. It's a little unit not much bigger than a microcassette that is supposed to be able to back up a GB on a single cartridge. Unfortunately, I got no tapes with it, and the only source I've found so far (www.datasonix.com) is pretty pricey considering I don't know if it works. Anyone know of a cheaper source for these tapes? Thanks! --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Jerry Pournelle Parody

by jfoust＠threedee.com

At 06:19 PM 7/31/98 -0700, Kai wrote: >I just had to pass this on to the list. >http://shell.rmi.net/~bslatner/humor/pournell.html The parody mentions his kids - week before last, I bumped into Alex Pournelle walking around in one of the computer history exhibits (where one of my Teraks was on display) at the ACM SIGGRAPH computer graphics convention in Orlando. For many years while I was working as a freelance writer, I'd see Jerry in person at press events at computer shows, and I knew many of his assistants / toadies. Ugh. It was frightening what he was given, and how little time he spent with it, and how little he understood it. Alex has certainly inherited or adopted many of his father's traits, including the condescending dismissal and endless bumming of software and hardware. He and another writer are working on a WinNT "studio" book, and are gathering all the 3D and video stuff they can find - but of course, many writers do all that. Where does it all go? It depends. The more pricey the toy, the less likely someone gets to keep it forever. Software often has no value on this spectrum, and stays in the hands of the reviewer, who might keep it or even resell it. (I was once appalled by the brisk cash gathered by a "reviewer" of books for a newsletter for librarians, who'd turn a bagful of new books into cash each week at the nearest used book store, after dismissing each with barely a paragraph "review".) For someone of Poor-Nelly-ian magnitude, you've ultimately got to *hire* someone to be in charge of returning and donating all the stuff that arrives. Keep in mind, a great deal arrives unsolicited. I note that the parody was written by Ed DeJesus, an actual editor at Byte, who oversaw my first and last Byte article (see <http://www.byte.com/art/9507/sec8/art5.htm>. I recently saw a summary of the mindset of the Pournellian branch of science fiction as "Space is like Texas, only bigger." - John

Compaq

by bill.sheehan＠stoneweb.com

Reminds me of a trick Penn Jillette (of the magician duo Penn & Teller) thought somebody (somebody other than *him*) should try on their laptops next time they pass through an airport: AUTOEXEC.BAT echo ARMING.... echo ARMED echo 10 echo 9 echo 8... (Note: This may well be a federal crime, and I don't recommend it. It's also a bad idea to call and wave to friends in airports ("Hi, Jack!") and to disparage the in-flight movie ("'My Best Friend's Wedding?' What a bomb!"). -- Bill Sam Ismail <dastar(a)ncal.verio.com> on 07/22/98 08:20:58 PM Please respond to classiccmp(a)u.washington.edu To: "Discussion re-collecting of classic computers" <classiccmp(a)u.washington.edu> cc: (bcc: Bill Sheehan/Corporate/SWEC) Subject: Re: Compaq On Wed, 22 Jul 1998, Tony Duell wrote: > As I mentioned once before, I once carried a VR201, by its handle, on a > train.

Sun-2/100U The Next Chapter

by karlm＠blitzen.canberra.edu.au

Hi again, Thanks for all the help with getting the thing booted, I managed to get the miniroot installed on xy0 (an aging Fujitsu M2322K on a Xylogics 450(451?) controller), and it boots quite happily off the miniroot into single user mode, the SunOS install program is quite advanced for 1986, and very easy to use! Just select the packages and put the tapes in when asked. Along the way i've noticed that one of my memory cards seems to be faulty, it currently has 7mb of ram (4mb + 1mb + 1mb +1mb), after numerous "Protection Bus Faults" I removed all but the 4mb card, and all is fine, i was able to up it to 6 and isolate the faulty card. I'll probably end up replacing most of the 4164 chips on that board, i think I have a box full of them somewhere :) The only problem I seem to be having is that, the first time I installed SunOS, when it goes to boot multiuser, it stops at "Using 100 buffers containing xxxxx bytes of memory" then appears to write continously to the HDD, (I verified this by clicking the WP switch on, and it dumped errors everywhere). it's not the rc files, i'll have a go at reinstalling SunOS again and see. There appears to be another problem, I don't have the manufacturers bad block data for the drive, and as such when i reformatted the drive it has no bad block info.... Now I did try "scan" in the diags to rebuild the bad block table, at which point it filled the bad block table and declared the drive unusable. I am slightly dubious of this, as the format/verify then failed where it had worked previously. Resetting the drive returned things to a sane state, and the format/verify completed correctly... any ideas? On the up side, the Tapemaster 1/2" tape and the ethernet interface is working, when it does finally work it'll be plugged into the university LAN....should make an interesting curiosity :) Cheers Karl ------------------------------------------------------------------------------ Karl Maftoum Computer Engineering student at the University of Canberra, Australia Email: k.maftoum(a)student.canberra.edu.au

Hi, MS Softcard

by timhotze＠hotmail.com

Hi everyone. Just to let you know, I'm not dead. (Boos, hissing, please.) Anyway, I found a MS Softcard for an A2. Serial# (if it matters) 2-189 18227. Full docs, all disks, packaging, etc. Now, for someone who has 2 or more: What's a good garage-sale-old-used-hardware price???? (It's a frends, but I want to pay hm to remove the guilt.) Pleae reply to worldsfate(a)geocities.com (Yes, that's not this addresss, but I can't get my HPC to send from it.) Thanks for any info. Tim D.

However, the easiest and safest way to put a thermometer into a bung is to insert a borer first, slide the thermometer down the borer, and remove the borer leaving the thermometer in place. One of the first things I was taught on the lab techs course years ago (the second thing was how to deal with a kid who has a thermometer impaled in the hand). -- Pete Peter Turnbull Dept. of Computer Science University of York

Actually, you want exactly the opposite if you're cutting it -- a very acute angle, so the rubber is sliced thinly with minimal effort. You want to slice it rather in the manner you would do wood turning with a turning chisel. -- Pete Peter Turnbull Dept. of Computer Science University of York

old modems & a packet switcher

by allisonp＠world.std.com

< No, I was thinking about differences in ground potential between the < two buildings, static electricity, lightning strikes, that sort of < thing. All the canonical reasons why you wouldn't want to pull < Ethernet coax through that conduit. Use thick eithernet wire as its coax and uses ground and everything uses an isolated interface to it. AUI is imune to ground loops and can be burried. The other approach is RS422/485 type interconnect as it is differntial. Myself I'd sink several peices of weather proof coax and build on that using AUI (thick eithenet). If you have a choice go underground as air trips invice lightining. Allison

In the workshops I've seen where it's handled, it's usually done with a very sharp tool with a very acute cutting angle (I've seen razor blades mounted in a holder for this) and lubricated with glycerine. For some jobs, I've seen a tubular cutter (rather like a cork borer) mounted in the tailstock and pressed into the workpiece, similarly lubricated with glycerine. -- Pete Peter Turnbull Dept. of Computer Science University of York

Some thoughts: With many of these devices, it takes (at least) two to tango, and of course you never find both together. (What is the sound of one statmux clapping?) Synchronous modems often didn't just carry the data from one end to the other, they also provided clock signals to the DTEs. Many DTEs expect to see those clock signals and won't originate them, so getting two nearby ones to talk over direct cabling can be an interesting proposition. Some of us probably worked with this stuff back in the days when it was new (1983-1989 in my case). "Fun" is not the adjective that comes to my mind. > How about running a T1 line between the > house and garage? With appropriate routing, its performance can be quite > suprising. Can you do this over dry copper, for short runs? If so, would you want to? You mentioned in another post that you'd have to run conduit for FDDI, and that makes me think there might be some open space between hither and yon. Sure, you could run copper, but wouldn't electrical potential differences be a problem? I know that we used to have a fiber run under the parking lot at the office, and Ethernet-fiber bridge things at the ends (two buildings w/parking lot between). > Does anyone on this list have any classic networking stuff beyond > ethernet/token thing cards? Not a lot, and mostly not by intent. Recently I got an HP9000/220U with some extra boxes that I believe are a CSU and some flavor of mux. No, it's not at all clear to me why they were piled together into one lot; the 9000 didn't have the right sorts of I/O for this. -Frank McConnell

Thanks...

by Anthony.Dellett＠Staples.com

Thanks to everyone that was helping solve our PDP-11 boot problems but it seems that part of the problem was the fact that the backplane was giving out (it actually went up in smoke on friday night while we were playing with it, as did the front panel to my IMSAI, what a night that was). So again, thanks... Tony Dellett PS: If anyone in the Massachusetts/New Hampshire area has a spare RX01 that they wouldn't mind parting with, we have alot of Q-Bus cards that need a backplane :) Tony

old modems & a packet switcher

< Hmmm. Well, I wonder about this. I know such services exist in the US < well, but they still at least have battery on the line. I would wonder < what good a dry point-to-point connection through the telco would be ove < several miles, where the resistance in that length of wire would absorb < whatever voltage you put on it. The service exists, I used to use it 25 years ago for remote base stations (radio service). It was called a dry copper pair and went point to point with NOTHING else. It had to be that way as you would put audio on it and DC on it to either key the transmitter or disable to tone squelch. the average circuit resistance ws about 1kohm/mile. So the remote end didn't sense voltage but instead sensed current (~8-9ma) and polarity to do switching. Audio was put on the pair the normal way (differential via transformer). Allison

>> Okay, I've now given up hope that those old modems will ever be >> at all useful or interesting to me. So they're up for grabs, >> for the cost of postage. just a thought, but were these modems ever designed to connect to a public network? I've got a couple of old BT modems that seem to be designed to only work on a private, internal network (at least that's what the manuals imply), so maybe line voltages are different or whatever... cheers Jules

In the "I have my suspicions" dept.

by william＠ans.net

I finally took a good look at that new PDP-11/23 I purchased some time ago. It seems to have some normal looking DEC cards in it (LSI-11/2, others). It does, however, have an interesting looking card set from Associated Computer Consultants, called "MDMA" (as far as I can tell). It appears to be from the mid-1980s. One card contains some sort of engine, with ROMs and (4) 2901s. The other card contains a bunch of glue and interface stuff, and has a connection to a big round military type connector (the modern versions of the Cannon connector) on the back panel of the chassis marked "IMP". Being that this computer came from a certain spooky branch of the U.S., that "IMP" looks awfully suspicious. Could this little DEC box have been slated for the ARPAnet, but came just a little too late? All I have is the processor - no drives or OS, so I can not tell much if I power it up.

< I'm surprised by this. I'd thought about ways of linking any number < of old PCs at up to 2000 foot distances, and thought about recreating a 2000ft is within the capability of RS422 at data rates that are in the megabit range. There are other simple solutions like RS423 at low data rates. The DEC mill used to have many central systems that often were remote from the users by as many as 6 floors vertically and several hundred feet horizontally. (Royalt was ML11/M1 and our group was ML3-6/A1) we still ran 4800 or 9600 serial over the 500+ feet of wire of the standard dual twisted pairs of phone co wire. The biggest problem was the possibility of ground loops. With care that's can be avoided though RS422 (balanced differential) can deal with that as can RS485. Allison

You can if you have the right tools. Grinding is easier for most to do. I make TU58 drive wheels using thickwall rubber tube or tygon and mount the assembled result on an old tu58 motor and "grind" on a bench grinder. I get a good round smooth surface, minimal setup. The hub used is the one with the tire turned to goo, with the goo removed. < For some jobs, I've seen a tubular cutter (rather like a cork borer) < mounted in the tailstock and pressed into the workpiece, similarly < lubricated with glycerine. For general shapes its ok, the deformation affects accuracy. We used that to get the general shape (tubes or plugs) and then mounted them and did final grind. It was what the chief engineer wanted. Generally the size of the drive roller is allowed considerable latitude but roundness is desirable. Allison
