ISO Integrated Solutions 4.3bsd binary distrib 4.0 or later

by aek＠spies.com

I've slowly been working through the box of carts that came with the ISI system that I just picked up from Erik Klein, but there doesn't appear to be a complete binary distribution tape set in the pile. An image or physical cart of a version from '88 or later (4.x or 5.x) would be helpful in trying to get the system going again. Just to get it saved on line somewhere, the format of the cartridges is a little tricky in that ISI tape controllers simulate variable blocking on QIC cartridges by appending 512 bytes of data in front of the actual data blocks. The first few bytes are all that matter for example: A1FE 0001 0002 2800 0014 is a magic number, file number, block number, and block length (10240 bytes)

Web forums are not friendly to some browsers. They're also slow. Mail delivery is indeed push, not pull; by the time it gets to local delivery reading is just opening a local file, which is rather different than downloading a page on a server at the same time as umpteen other people. And it's a damned sight easier to search, sort and filter a mailbox (local, or IMAP) than a web page. I'm with Cameron, Sellam, and Jules. And probably a few other people who wouldn't want to use web technology because they have to be online at the time they are reading, all the time they're reading.

RT11 sysgen and disk partitions

by gordonjcp＠gjcp.net

OK, next load of questions. I've been trying to create a "virgin" system from the install media I have. I have so far successfully sysgenned and built RT11 v5.0, and installed it on an RL02. Great. However, the version that boots off one of the hard disks built into the PDP allows me to access four partitions in total - DU0: to DU3: - but my own version only has DU0: (same as normal) and DU1: (same as DU3: in the version of RT11 installed on the hard disk). If I say "SET DU2: disk=0, part=1" then I can see my "old" DU1: as DU2:, and so on. What do I need to change to get it to come up like this? It doesn't appear to be a load of "SET" commands in the STARTS.COM file. Gordon.

Big list of floppy disk formats?

by dm561＠torfree.net

From: Jules Richardson <julesrichardsonuk at yahoo.co.uk> Subject: Big list of floppy disk formats? Does such a thing exist? It'd be nice to have an online resource of all the different floppy disk formats used by different machines. Yes, that's one huge list, and would likely never be complete - but as I haven't come across an attempt at all so far, it'd be better than hunting around for the data when needed. I'd be happy to collate stuff if it's thought to be a good idea - I could make it available online too (although maybe one of the recognised repositories such as bitsavers would bea better place) Data can be fed into the futurekeep project as and when necessary, as it's something that'll be needed there too one day. thoughts? J. ---------------------------------------- You probably already know this, but 22disk's cpmdisks.def has a lengthy list of at least CP/M format details; good starting point.

Amiga Mouse & list datapoint for Jay...

by zmerch＠30below.com

Anyone have an Amiga Mouse (for use on a 4000T) for sale? It doesn't need to be pretty, but it does need to work. I checked ePay, but most are in Brittania where shipping would be a bear, and the few that remains are "parts" or bundles... Unforch, I'm in a bit of a hurry for this - it rides on getting the rest of the 4000T (which the owners have ever-so-quickly gotten in a big hurry to get rid of, but need to remove personal data first, and don't have the keyboard or mouse! :-/ ) I just got an Amiga keyboard on ePay, but alas, no easy mice... (not even the Atari/Amiga switchable ones... :-( ) Anyone have a working spare they're willing to sell? "Have Paypal, Will Travel"... Also... Jay: If it'll help you track down the Reply-To: address munging "weirdness" Evan's email address *always* comes up with the list address's's's; I always have to manually remove his address from the To: field when replying to a post of his.

That ensuing discussion lacks any useful detail. For people who haven't read it, here's what it said: "IIRC, Killdall stood up in court and entered a keystrokes at a PC running MSDOS and brought up an easter egg he had programmed into CP/M years earlier, proving they had used his code." What we're trying to figure out is the keystrokes and the MSDOS version. Here's another account: http://dfarq.homeip.net/article.php?story=935 "Back in the mid-1990s, PC Magazine columnist John C. Dvorak wrote something curious about this operating system. He said he knew of an easter egg present in CP/M in the late 1970s that caused Kildall's name and a copyright notice to be printed. Very early versions (presumably before the 1.0 release) of DOS had this same easter egg." John A.

Free SS1000 for Boston-area pickup, needs new fan/sensor

by classiccmp＠crash.com

Free to a good home: Sun SPARCserver 1000 (not E) with one disk tray and one processor board. Includes two SM51 50MHz SuperSPARC CPUs I believe, 96MB of RAM (one bad DIMM in last bank), and 4 x 500MB SCA drives in "spud" brackets in the disk tray. PROM monitor reports a fan failure, though there are several working - might just be the sensor or cable, but Solaris 7 wouldn't load as long as this failure is being sensed. Chassis/case itself is in decent shape, some sticker residue, and it's heavy. I'll consider delivering it if you're 15 minutes away from Arlington, MA, but otherwise you'll need to pick this thing up or pay for the UPS Store to pack it - I'm not packing it for shipping. And of course you'd then have to pay shipping... First come, first serve... Thanks for the bandwidth, --Steve. smj (a) crash (d) com

Because they can be used to break car windows quickly, cleanly, and quietly. They are popular with car thieves. (much as dent pullers can be used to yank out the ignition switch). If you have just a center punch on you (or one with a bunch of other tools), you likely won't have an issue... on the other hand, if you are walking around the streets at night, have a center punch, dent puller, screw driver, and pliers... you best be on your way to hot wire your OWN car, of you will probably find yourself with a bunch of explaining to do. >Centre punch, cordless drill, >Citroen Special tool BFH-14 (Big, um, *Friendly* Hammer, 14lb), >boltcutters, hacksaws, sockets, spanners, screwdrivers, that kind of >stuff.

MS Network Client under DOS 3.3 working

by vcf＠siconic.com

For what it's worth: I got Microsoft Network Client working under DOS 3.3 on a 386/33. It works very well. I was able to connect to my WinXP system and copy over just under 500 files. I also got it to work reliably with a 3Com Etherlink III. Before, I whined that it kept crashing. Well, this time when I was setting up, I realized that the MSNC setup program advises that it will use more memory to optimize network performance but gives you the option to forgo optimization. I had it forgo optimization, and I think that made all the difference. At some point, if it becomes necessary, I'll also test on an 80286 and even an old XT system. Once again, if you want to download MSNC, I have it all bundled up in a zip file here: http://www.siconic.com/download/network/ (Note: I changed the location from where it was before.) This directory also contains the 3Com 3C5x9 configuration utility, but it's also included in the ZIP file, so no need to download it separately. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Web forums vs mailing list (was Re: minor list changes)

by dave04a＠dunfield.com

>Given the task at hand, given the needs of the users, given the >recently described hassles, is mailing-list technology the best >design and solution for this task? I prefer the mailing list for several reasons: 1- I am on dial-up. I can just "let it download", and then come back to read the messages as quickly as I like - web based clients are SLOW on dial-up, and you have to be there to click on every item you want to read, so you have to wait for it. This by itself would probably be a show stopper for me. 2- The list comes as nice plain text. If I want to save something, I simply save it - Saving text from the web is usually (not always, but usually) much more a pain in the butt. 3- Many sites nowadays use "extensions" and other goodies (and I use the term loosly) which make them unreadable on my anicent browser... It's fine to say "you just have to upgrade your browser", however there ARE no newer browsers for the particular platform that I use - If staying connected to this list means that I have to change to a "modern" OS, then I would simply wave goodbye and bow out. I expect there are a few others who would do the same... 4- Another point relating to #3 - this system I am using does not EVER download a "plug in" or applet and run it - attachments that I do accept NEVER automatically launch themselves (and if they did, they wouldn't know how to run here) ... so this machine has no "anti virus" software, doesn't need it, and never gets "infected" (because it never auto-runs anything). I have no doubt that a web based interface would have all kinds of neat-cool java applets, plug-ins and other things which compromise security - Even though the "list" site might be safe, forcing people to turn these things on will cause trouble for those of us who choose to avoid them. 5- The mailing list has an element of privacy - Since you have to both know about it and manually subscribe to it, there's a good chance that by the time someone shows up here they really are more than casually interested in classic computers. Once we get links from non-classic sites (hey, here's a place where I've seen XP installs discussed), and indexed by the search engines, you can bet that non-topic material will rise.

picking locks

by Saquinn624＠aol.com

I haven't had very good luck with paper clips. A better tool is a used dental pick, because this is tempered and holds up when you put stress on the lock with a tool (screwdrivers are not the best tools to use, as they can dent/flatten the lock noticeably, but in absence of a better tool they work.) Put the screwdriver in, apply pressure, stroke the lock pins with the pick. If you're really into it, you grind and temper a thin tool with a bump at the end. The computer locks I've seen (excl. IBM Medeco) don't need this, though.' -Scott Quinn

8-bit low profile ethernet card?

by nemesis-lists＠icequake.net

I'm looking for a 1/2 to 2/3 height 8-bit ISA Ethernet card. It's for an embedded type application. I can find "short" cards in terms of length, but not in terms of height. Anyone have any leads for me here? :) -- Ryan Underwood, <nemesis at icequake.net>

Big list of floppy disk formats?

by julesrichardsonuk＠yahoo.co.uk

Does such a thing exist? It'd be nice to have an online resource of all the different floppy disk formats used by different machines. Yes, that's one huge list, and would likely never be complete - but as I haven't come across an attempt at all so far, it'd be better than hunting around for the data when needed. I'd be happy to collate stuff if it's thought to be a good idea - I could make it available online too (although maybe one of the recognised repositories such as bitsavers would bea better place) Data can be fed into the futurekeep project as and when necessary, as it's something that'll be needed there too one day. thoughts?

Chorus Systemes?

Anyone know anything about Chorus Systemes and what they were up to circa 1990? I'm just unravelling a lot of old internal Acorn code/documentation and the name's cropping up quite a bit...

It is a little hard to describe from this sense. You could pick stuff with the select and then you execute it. It would be hard to create a software only emulator. The physical keyboard was as important as the software on this machine. Talking with Jeff, he said that several efforts have been made to get the keyboards on PC to work but there are just too many variations on how the keyboards are handled. It was left too much up to the builder of the machines. You really need low level access to key strokes and the layout is wrong as well. Dwight

minor list changes

by jwest＠classiccmp.org

I changed two things on the list setup tonight. 1) To subscribe to the list (new subscribers, not you guys), requires not only a confirmation email, but also list owner approval. I'm having way to much trouble with "people?" joining the list and all their email immediately bouncing. It gums up the speedy delivery for everyone else. 2) I changed the max time in queue for any message (outbound) to 35 minutes. This means the server will try to send email to you once, then again 30 minutes later, and then it will just give up on you. It won't unsubscribe you at that point, it takes like 7 days of bounces to get you unsubbed. But it won't try to send you any given list post more than twice now. Same reason as above. For those sendmail inclined.... I considered setting up a secondary queue for slow delivery where any emails that take longer than X time get moved to a low priority queue. Quite frankly, I don't want to deal with it. I'd just get more complaints about posts being out of order ;) Jay

8' drive on PC troubleshooting

by dave04a＠dunfield.com

All the discussion on stacking two PC supplies and cutting grounds to try and keep them isolated seems like asking for trouble.... I've had good results using a PC-AT supply, and a little homebuilt linear (and nicely transformer isolated) 12v supply stacked on it's output to power an 8" drive. (The 12v supply is actually built on the outside of the cover of the AT supply).

FS: ThinkPad 700C (SF Bay Area, free to good home)

by patrick＠vintagecomputermarketplace.com

I have an IBM ThinkPad 700C that boots Windows 95 (it actually runs nicely, I dare say better than Win2K3 on my current 1Ghz desktop). The display hinge is broken, so its aesthetics are lacking a bit, but if you've got another 700C that isn't working, this is a good machine for parts. Comes with power adapter, original docs, and battery (unknown condition). I'll ship to you for cost (US only, sorry), or if you're local you can pick up. If there are no takers, I'll be tossing it. Hopefully it finds a good home. It's a nice little machine, just outside my collecting scope. http://www.vintagecomputermarketplace.com/view.cfm?ad=1610 Thanks! Patrick

Catweasel opinions, sources of info etc.

by curt＠atarimuseum.com

Jim, I understand where you're coming from, however the way the product was presented, it stated it could read various formats, what wasn't mentioned on the site for the product or during the purchase process is that the "product is capable of reading such formats - if someone actually writes the code" My Atari 800 could run linux - if someone ports it, could run CP/M too if someone wants to write the needed code, could read IBM disks on its disk drives - if someone writes it... All of our equipment can do a lot more then it is normally capable of --- if someone takes the time to write it. So what I'm saying is I bought the product because it stated it could do certain things which I was expecting out of the box when I bought it, just there was no fineprint saying that there were no actual s/w or drives to actually make the card work that way yet.

I think I looked there a while ago and gave up > when I saw how many PC posts there were. Actually it's alt.comp.hardware.homebuilt, and it started as a group for people interested in building or modifying hardware in the sense of using a soldering iron or perhaps VHDL, but gradually newbies started appearing and asking about PCs they had "built" in the sense of sticking their ISA cards on a new motherboard. At first they got politely asked to try elsewhere, but quite quickly, first one or two, then more, other newbies started saying "well, it was a polite question, with a simple answer, so why not just answer it?" and in quite a short space of time the please-help-me-fix-my-PC brigade outnumbered the on-topic posters by 100:1. Various solutions were tried but too late and all failed; eventually all the regulars moved elsewhere. Some started a new group called comp.arch.hobbyist; maybe not the best choice of name. It gets about one post a week. On a good week. -- Pete Peter Turnbull Network Manager University of York

Age

by alhartman＠yahoo.com

Well, I'm about to be 43, born June 21 1962 (exactly a year older than one of the other posters recently...). I first encountered Personal Computers in 1978 at a Star Trek Convention where I poured $20.00 into a .50 a game Star Trek Game hosted on a TRS-80 Model I. I asked the author for his address so I could buy a copy, but I guess he thought that a 17yo kid would never buy a $1000 computer. By January 1979, I was the proud owner of a TRS-80 Model I, Level I, 16k computer. The Manager of the store said I didn't need Level II. Turns out he was having problems moving Level I machines, and was stuck with this one.. LOL! Shortly thereafter, I upgraded to Level II and went to work for Radio Shack. I bought an expansion interface in 1980 and I think I have the singular honor of being the only person I know whose warranty was voided BEFORE I took the E/I home. Being that I worked in the store, I took it home BEFORE I had finished paying the layaway, installed the 32k of RAM I had bought mail-order, tested it... And brought the unit BACK to the store. I bought my first Floppy drive for $321.00 which was an MPI drive that ejected floppies like a toaster. We never got that drive to run... I then got a Wangtek Flippy Drive (Two sided by turning the floppy over, it had two sets of sector hole and write protect sensors) and a Percom Doubler. I worked for an LNW Dealer in NYC (Stoney Clove Computers) and coveted an LNW Model I for some time. I also worked for Lawrence S. Epstein Assoc. and sold Corvus Hard Drives for the Model I/II/III, etc... I almost bought a ZX-80 instead of the Flippy Drive at the Trenton Computer Festival in 1980... Over the years I've owned just about every American Micro Computer: Atari 400/800, Atari ST, Amiga 1000/500, Apple IIe, IIgs, IIc, Laser 128/128ex, MacPlus, Duo 230, PB 1400, Wallstreet G3, PowerComputing Power Center 132, Power 100, ZX-81 (built in an hour from the kit), TS1000, TS 1500, TS2068, ZX-Spectrum (American Prototype), Coco I, II & III, All sorts of PC Clones starting with an American XT (8mhz Turbo V20) and currently with a self-built P4 3.2ghz. I worked for Zebra Systems and Spectrum Projects and developed a lot of products for the Timex/Sinclair and Color Computer Community... At Zebra, I used and fell in love with an Imsai 8080 upgraded with a Z-80 board. I did a lot of "typesetting" with a program called "FancyFont" on CP/M using an FX-80 printer and eventually a Laserjet 500. I also co-authored the Coco Greeting Card Designer while at Zebra and worked on the SC-01 Votrax Speech Synthesiser implementation on the ZX-81/TS1000 and the TS-2068. Two of the dream computers I'd like to own is an Imsai and an LNW-80 Model II. I ran several BBS's in the mid 80's: Rainbow Magazine BBS (5 lines), Omni*Net BBS, Outpost-80 BBS, Computer Concepts BBS, Zebra Systems BBS using mostly TBBS on TRS-80's. I helped develop a fork of Connection-80 BBS in NYC called "Nybbles 80" BBS with Paul Oves and Stoney Clove Computers. I added threaded messaging, passwords, and color... I was a Novell CNE from 1989 - 1996 (I never upgraded to 4.0 and above). Today, I am a network engineer supporting MacOS X Servers... I can't imaging my life before I had computers in it... I still have my TRS-80 Model I which has been heavily modified using the TRS-80 and Other Mysteries Book by Dennis Kitsz. It has Lowercase, High Speed Mod, Alpha Joystick built in, Reset Switch, Internal speaker and Amp, Composite Video Out, better keyboard with keypad... It's not working right now, it won't recognize either of my E/I's. It was stolen twice and recovered due to all the mods. It was easily identifiable, and I got lucky to get it back twice when stolen. I just bought a Mac Mini to add to my collection, and am selling my G4 500 on eBay to fund it... I put $50 into the coupon for an AmigaONE, and may be getting one of those this year too. That's it!

Windows LFN's (HP NewWave)

by julesrichardsonuk＠yahoo.co.uk

Just found the following snippet in a 1990 document (someone's review of a GUI show which they'd attended). Just struck me as interesting in that I never knew there was an alternative to 8.3 filenames in the DOS/Windows world prior to Win95, nor have I ever heard of HP NewWave before... Apparently also included macros/activity recording, associations between data and application (e.g. double-click on a spreadsheet file and it opens in the spreadsheet app etc.), and context-sensitive help. Sounds like a winner, only I've never even heard of it... Apologies to the original author (who almost certainly isn't on this list!) for the cut & paste! (I do like that first line :-) ------- NewWave is a 'front end' to MSWindows to make them useable. It provides a Filer facility which tarts up the MS-DOS filing system to enable 30 character filenames with no obvious character set limitations (ie it'll accept a space in the filename) and a framework to interchange and combine multiple data types into one document. This framework manages dynamic links between the document and the original object which is contained in the document such that when the document is reconstructed any changes to, say the spreadsheet data, get reflected in, say, the report. Parts of foreign objects can also be imported with the same results, eg a few rows and columns of a spreadsheet can be imported to a word processed document.

> Now that is weird. I read somewhere (or saw a survival show) that EVERYONE >should carry a center punch in their cars just in case you car gets >submerged in water. Use the center punch on you side windows to get out, >otherwise it would be impossible to open the door.... Although I can't dispute this idea, I've been curious exactly how hard it really would be to open a car door under water. You have air pressure inside the car trying to escape, and although the door would be slow, it shouldn't cease to open. But I admit, that is one of the few car accident scenarios in which I have not trained. (We don't really have deep enough water in my covered towns to be an issue... although we did have a car in a swimming pool not too long ago, but that was a first for us... a drunk guy drove down someone's driveway instead of the on ramp to the highway... when we got there, he still couldn't figure out where the highway was... and what a swimming pool was doing blocking the road.) I do laugh at those emergency tools that are now being sold for car owners (that thing that looks like a mutant hammer, it has a center punch, a seat belt cutter, and I'm not sure what else on it). With all the accidents I've seen, any that a person would have a need to use such a tool, they are either not in a position to use the tool, or not in a condition to use the tool (kind of hard to cut your seat belt if you are unconscious with the dashboard in your lap) Personally, I see those as just another sucker product. My same feeling would apply to anyone carrying a center punch specifically to break the window if you drive into water. How many times in the past HAVE you driven into water, and when you did, what was your condition at the time, and where was the location of the punch relative to you, and how long would it take you to get to it vs how much time do you have to escape. All in all, its kind of silly, because the only time you will need it, you likely won't be able to use it. (I carry one not for my benefit, but for that of others... mine is in my med kit in my trunk, so I couldn't access it for myself even if I wanted to) -chris <http://www.mythtech.net>

2.5V Lithium "AA" sized batteries: Where to find?

Yeah - I thought about that. Don't want to go there if I don't have to, though. (I did fail to mention in my original post that it requires 2 of these little beasts, thus making a 5V supply necessary.) > Also check out the oddball batteries available for > photo equipment. There's a lot of odd voltages in > that category, though you might have to slightly > modify the cell holder (widen it a bit). Yeah - thought about that, too. It is a fairly tight fit already, so widening the battery compartment doesn't look feasible. At this point, I'm thinking that if there isn't a direct replacement for this cell, I'll just pay the bucks to get it refurbished so it can use something more conveniently available. Appreciate the suggestions though!

11/45 progress

by jwest＠classiccmp.org

Based on the docs I got from Ashley I was able to re-arrange the memory section to be sane, cards were in the wrong slots. I was also able to get the jumpers set right on the G110 card. Now when I power up I can definitely read core correctly. There's a random assortment of data in sequential locations and returning to those same locations I always get the same value. That's a plus. However, I can't store anything. Anytime I store a new value in a location, that location gets all zeros. Moving to another location I get data, and moving back - zeros. So it appears to be challenged in writing, but not reading, memory. The plot thickens :) One thing I can't be sure of that the docs from Ashley don't say for sure is how to configure a less than full section of memory. I ASSumed you start >from right to left, but in the HP core section that would be a bad assumption. Humm... But if I had that wrong, I'm suprised I'd be able to consistently read memory locations. A different G231 and G110 and H214 didn't change the problem. Jay

PDP-11/23 ODT question

by wacarder＠usit.net

Yesterday I picked up a 6 ft rack loaded with a PDP-11/23, two RL02 drives, an RX02 drive, an RL02 pack, 3 boxes of RX02 floppies, and a bunch of cables. The rack was complete with side panels and top pink/purple panel. Today I figured how to get all 400+ pounds of it out of the back of my pickup truck and into my shop with just me and my wife. I then hooked it up to a VT100 and powered it on. It comes up with an octal address (177something) followed by the @ prompt. I'm used to unibus M9312 console emulator prompts and the 11/03 prompt where you can type in a two character code for a supported device and it will attempt to boot that device (ie DL, DX, etc). I'm going to search for the 11/23 ODT info, but in the meantime if someone can give me a quickie command set so I can try to boot off the RL02 or RX02 drives, I would greatly appreciate it. Is there a command to tell it to boot from the RL02 or RX02? Thanks in advance for any help that anyone can provide! Off to Google for 11/23 and ODT commands and to check Al's bitsavers. Ashley

Hmm, I have sent this to the list earlier. Perhaps it did not make it ... The M7800-YA is the current-loop only version. > Jay wrote about a DL11: > If I exam 776500, I get a 200, > but anytime I store a value and read it back, there's all > zero's in the data register. I will dig up my notes getting characters in and out a M7800 in my 11/35 resurrection using the front panel several years ago. This is also an advice: make notes of *everything* you do on a system, no matter how trivial at this time. Changing a wire, trying some toggle in tests on the console, behaviour, measured voltages on pins, etc. If problems occur later you can go back and do all tests from your notes. That's why I can write my tests with the M7800 when I get home (in a few hours from now). - Henk, PA8PDP. These are a few of my notes. Console board: 2 versions. M7800 and M7800-YA M7800: Xtal = 4608 kHz, has 1448/1449 jumpers: A3,A4,A5,A7,A9 open: A6,A8,A10 base address = 776500 baudrate = 1200 Bd. M7800-YA: Xtal = 1152 kHz, no 1448/1449 (20mA current loop only) jumpers: A0,A7 open: A4,A5,A6,A8,A9,A10 base address = 777560 (console) baudrate = 1200 Bd. console registers: RCSR 777560 RBUF 777562 XCSR 777564 XBUF 777566 Hit the key "1" of the keyboard If RCSR contains 0200 it means that a character is received. To check this: 1) set the SR to 777560. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777560 3) press EXAM 4) the DATA LEDs show 000200 RBUF should contain 061 (ASCII "1"). To check this: 1) set the SR to 777562. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777562 3) press EXAM 4) the DATA LEDs show 000061 Load 065 in XBUF --> the screen should show a "5". Operation: 1) set the SR to 777566. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777566 3) set the SR to 000065 4) press DEP Simple test of the CPU. 1) set the SR to 777570 (the switch register address). 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777570 3) set the SR to 000777 (this is BRA . branch to myself) 4) press START The ADDRESS LEDs show 777572. CONSOLE LED is off, RUN, BUS, PROC LEDs are on. When you press HALT, CONSOLE LED goes on. - Henk, PA8PDP.

It's easy to add the parts; I've done it a couple of times. AFAIR, to get the full version, it's three RS232 chips, half a dozen resistors, and a capacitor. Maybe a diode. In case it helps, here's the pinout of the Berg connector, and the connections to make an RS232 cable and a 20mA loop cable. The "interlock" may require some explanation... The seril out from the UART is connected to both the RS232 and 20mA buffers, so when it transmits, it does so on both. However, you don't want both to be connected to the UART receiver at the same time, so you have to jumper *either* the 20mA receiver *or* the RS232 receiver to the UART, and this is what the "interlock" does: Numbers are DB25 pin numbers (for the BC05C) or Mate-N-Lok pin numbers (for 7008360): Berg pin Signal BC05C 7008360 A Ground 1 Prot.Ground (blue/wht) - ground B Ground 7 Signal Ground (brwn/wht) C 25 Force Busy (red/org) D 13 Secondary CTS (org/red) E TTL serial in - interlock in - interlock in F EIA serial out 2 Transmit Data (wht/blue) H 20mA interlock - interlock out J EIA serial in 3 Receive Data (org/wht) K +20mA serial in 7 + Rec.Data (green) L 24 External clk (brwn/red) M EIA interlock - interlock out N 15 serial clk xmit (grey/grn) P 19 Secondary RTS (lbue/blk) R 17 serial clk recv (grey) S -20mA serial in 3 - Rec.Data (red) T 5 Clear To Send (grn/wht) U V EIA RTS 4 Request To Send (wht/org) W 10 -ve power (wht/grey) X 22 Ring (blk/org) Y 9 +ve power (grey/wht) Z 6 Data Set Ready (wht/grn) AA +20mA serial out 5 + Trans.Data (white) BB 8 Data Carrier Detect (wht/brwn) CC DD EIA DTR 20 Data Terminal Ready (blk/blu) EE -20mA RDR Run 3 - Reader Run (black) FF 11 202 Secondary TD (blu/red) HH JJ 12 202 Secondary RD (red/blu) KK -20mA serial out 2 - Trans.Data (black) LL 14 EIA Secondary TD (grey/red) MM 21 Signal Quality (org/blk) NN 16 EIA Secondary RD (red/brwn) PP +20mA RDR Run 6 + Reader Run (black) RR 23 Signal Rate (grn/blk) SS TT +5V DC UU ground VV ground -- Pete Peter Turnbull Network Manager University of York

Amateur electronics questions, but almost on-topic

by Saquinn624＠aol.com

I have a couple of questions that I haven't been able to find in my books. (1) there has been much discussion in this list about capacitors failing. I recently had a cap on a QIC-24 drive fail with a bit of sound and fury (axial tantalum). Is there any way to test for this other than desoldering every cap (at least every electrolytic) and testing it on a cap meter? I don't want to fry my IMSAI, but there are a lot of caps in there and it would take forever... (2) (flame risk) My Tek 555 popped and blew a fuse when I had it plugged in last. I disassembled the PS and cleaned off the dust, and I want to test it by itself, but the power-on relay won't close. Any hints, or is this like amplifiers where the tubes need a load? - Scott Quinn

An old portable radio with a 90V battery comes to mind. My solution to the problem has been to use a regular battery that will fit in the space along with a buck or boost converter to generate the total voltage required. In your case I would use a regular alkaline AA in one compartment and a boost circuit in the other. Your use might not be quite as long as that of a Lithium, but alkalines are cheap.

9000 VAX wrote: > I guess the lab computer uses 5v CMOS devices and the > 2x2.5V battery let them skip the voltage regulator. That does have rhyme & reason to it -- yes. (And you are correct in that it takes 2 of these 2.5V lithium cells -- I failed to mention that in my original post.) I suppose it just couldn't have been foreseen by them that SAFT would discontinue manufacturing this particular battery at some point down the road. Still, though, wouldn't manufacturing a device which relies on a sole provider for its power cells raise a flag or two during the design process? It is not like these batteries are as common as dirt -- like your typical Duracell "AA". (Then again, I'm no hardware engineer, so I'm not familiar with how these decisions are made.)

Yup, that is exactly the kind of law it is. It really isn't enforced by itself (they don't round people up for owning lock picks), it is just used as an aid to arrest/detain someone that you have a really strong hunch is up to no good (and as a way to confiscate the tools from someone that you are sure plans to use them to commit a crime... this is done in inner city schools when kids pass thru metal detectors and are found to have various items that have perfectly legit uses... but you know the kid doesn't have it for one of those reasons... box cutters are the most common item) -chris <http://www.mythtech.net>

Where are the young people on the list ? ;-) I'll turn 23 in a month and have been working on oldish and "cool" computers for approx. 7 years now. Started with a Philips P3200 (286, heavy stuff) which infected me with the bug... I can't talk of nostalgia as my machines are mostly from the time, I couldn't walk yet... DEC and CDC stuff, but also some SUNs from the time I started going to college. There's also stuff before I was born, like my PDP-8/a. It's funny to think about that. As adrian said, nostalgia from my time would be 386 and 486 and so on, which obviously aren't very interesting to investigate time on. Moreover, there's nothing you can repair on these things by yourself...

2.5V Lithium "AA" sized batteries: Where to find?

by elf＠ucsd.edu

[This post involves a hand held lab computer, of which this particular model was made/purchased about 15 years ago. Similar models have since been made, but without the problem I describe below.] I have a hand held lab computer (manufactured & purchased in 1990) which takes quite an unusual battery. The battery is the size of a regular "AA", but is 2.5V Lithium. The company who used to manufacture them (SAFT) no longer does so. The SAFT battery model # is "LCP 6". Picture of battery (and a regular "AA" for comparison): http://home.san.rr.com/instep/saft-lcp6.jpg (~42KB) Picture of lab computer: http://home.san.rr.com/instep/labpartner-front.jpg (~58KB) http://home.san.rr.com/instep/labpartner-back.jpg (~44KB) The company who made the lab computer still offers to refurbish the unit for a new (more readily available) lithium battery pack, but I want to avoid doing that if at all possible. They also don't have any suggestions as to where to find a 2.5V Lithium "AA" sized battery. AND -- I've Google'd high & low for an equivalent, but nothing pops up. So I've come here to ask: does anyone know if an equivalent battery exists? (And what's with the designer(s) decision to use such an obscure battery type?)

2.5V Lithium "AA" sized batteries: Where to find?

Also check out the oddball batteries available for photo equipment. There's a lot of odd voltages in that category, though you might have to slightly modify the cell holder (widen it a bit).

Yes, as the sole owner of Harhan Engineering Company I of course have total control of the Harhan.ORG and Harhan.COM domains, but why in the hell should I spend money on a backup server just because YOU decree so? Many many many original ARPANET sites did just fine with one single mail server for the organisation. It was a Classic computer, like a VAX-11/780 running 4.2 BSD UNIX, or a FOONLY running TENEX, or whatever. They were kept up diligently with tender loving care, just like I maintain my VAXen, but boards DO go bad sometimes, and PROPER hardware troubleshooting (the kind that Tony Duell practices) takes more than 35 min.

MS Network Client under DOS 3.3 working

picking locks

>> I haven't had very good luck with paper clips. A better tool is a used >> dental pick, because this is tempered and holds up when you put stress on > >Or just buy a set of lock picks. They're not expensive. I think I >paid under $15 for a reasonably nice set. Depending on where you are, owning a lock pick set may be illegal if you do not have a reason to own one. Last I knew, lock pick sets were illegal to own in NJ unless you are someone that has a "legal" use for one. Of course, since legal use isn't really defined, it leaves it pretty wide open. (It is also illegal to have a police scanner in your car, as well as carry a center punch... again, unless you have "legal" reasons for the above... of course, being a volunteer firefighter seems to get me past the legal requirements for all of the above... so naturally I own all the above... and carry a center punch in my car most all the time, as well as a lock pick set in my tool bag) Of course, IANAL, and I could be mistaken on the laws, or the exact forms of them... but it is a heads up for those that may be planning to purchase a lock pick set and run around with it in their back pocket... they should just verify that they are allowed to do such before they find themselves being accused of being a terrorist ;-) -chris <http://www.mythtech.net>

I have it too working under VMWARE for running programs that no-longer work under Windows XP DOS windows (e.g. Turbo-C). However, I do not have the library that allows programs to use the IP facilities. If anybody has this library, please let me know. Microsoft used to have it on their web site, but I can't find it.

Color ASCII terminals

by rcini＠optonline.net

Hello, all: Looking for recommedations for a color ASCII terminal for my computer lab. I know about the B&W/green vintage ones (ADM, Hazeltine, etc.) but I'm not too familiar with color terminals. Are there any that look reasonably "vintage" or is that a pipe dream?

Calling PDP8 / OS8 /basic gurus!

by ron.hudson＠sbcglobal.net

I am running OS8 on a pdp8 simulator in my iBook. I get the . prompt, I run BASIC, type in the single line 10 PRINT "HELLO WORLD" RUN it prints out the header, then prints ME 10 Well, it's a very simple BASIC statement, did I get it wrong? (or is the simulate broken?) It's a nice simulator with a front panel-blinkenlights Anyone know how to boot the PASCAL-S Disk? The simulator has a menu selection that fat fingers in the RK8-E boot loader (strictly cheating I know.) but once that is set in motion nothing seems to happen.

Cromemco Software - what to do with it?

by mhscc＠canada.com

--------------Original message: Date: Tue, 1 Mar 2005 07:08:16 -0800 (PST) From: Vintage Computer Festival <vcf at siconic.com> Subject: Re: Cromemco Software - what to do with it? On Sun, 27 Feb 2005 mhstein at canada.com wrote: >> There are numerous systems out there, and Herb and Howard et al are >> doing a great job of archiving the documentation, but what about the >> software?

Randy has suggested that Gaby might put it on her site, so that might be the answer. Maybe those of us who have some Cromemco S/W could get together here or off-list and compare who's got what. How about it Randy, you're doing such a fine job with the 8"/3.5" issue, feel like organizing something else? It's even relevant... ============== >> For that matter, is there any point?

And it only takes the space of a floppy disk (or no space at >all once it's been converted over to a modern hard disk). -------------------------- Well, that brings up the second point: if it's going to be archived on the 'net, in what format? As discussed elsewhere, PC images of Cromemco disks can be a problem because of their SD/DD mixed format. Ordinary CDOS files are less of a problem since they're 8.3 file names with no subdirectories; they can fairly easily be copied to a PC & ZIPped, and copied back to a CDOS disk. CROMIX & UNIX files are a little more problematic, because of the long file names & subdirectories. They can be TAR'd, but again, Cromemco being Cromemco, they used several incompatible TAR/TARZ80/FTAR formats. BTW, Cromix V31.58, for example, consists of 10 FTAR disks, although the Z80 versions are much smaller (2 disks) And of course there's still the problem of the mixed format boot disks. Any thoughts/a consensus? =============== >> So, any ideas what to do with it? (no obscene suggestions, please!) >Stick it up your hard drive? ------------------------------ Well, that's what I've been doing, but a good dump would be welcome :) Just need an appropriate site. =============== >> BTW, any news about what happened with Don Maslin's collection? >I'm wondering the same thing. ------------------------------ And what about Al Kossov's site? mike

It is interesting to note that when I read this mail on gmail that one of the adds posted was for lockpicks. They are not illegal in Oregon nor are Scanners. The only scanners illegal here are ones that scan the cellular band and that is a federal rule. Paxton Astoria, OR

picking locks (OT)

by cb＠mythtech.net

>Guess I'll be hunting for a centre punch too ... You can get one of them at any decent tool dealer (or any non decent dealer that sells more then 4 plastic handled screwdrivers). A center punch's "true" purpose is to mark or ding items. ie: before drilling a hole in a metal sheet, you can use the center punch to ding the metal so the drill bit won't slide around as it gets started. They are really handy for breaking tempered glass cleanly. (just never use one on your leg, as I found out the hard way... it hurt so much I thought I exploded my femur). -chris <http://www.mythtech.net>

However, I didn't really try searching too hard... so they may still be worth looking into (mine came with a book on how to use it as well... I've never gotten very good at it however). I think I may have also seen them at one point in an MCM Electronics catalog (same set I have with the book). -chris <http://www.mythtech.net>

Altair32 Emulator "Easter Egg" idea

by rcini＠optonline.net

All: I had an idea for an Easter Egg within the Altair32 Emulator. I remember a story that you could run a certain program on the Altair and hold an AM radio next to the Altair and you would hear music. IIRC, the song was "Daisy" as was played in 2001: A Space Odyssey. Does anyone (1) have this program in source and/or binary and (2) can someone make a high-quality WAV file of it for me (since I don't have an Altair)? I figure I could take some liberties within the emulator code to checksum/MD5 hash code loaded into the emulation space and if the music binary is loaded, it'll set a flag which when RUN is toggled, the WAV would play. Wadda 'ya think?

>I own more than one hundred locks, and sometimes I can't find the key to >open one. In some cases, I purchase equipment with locks but no keys. >So I think I have an entirely legitimate use for lock picks. Whether a >court would agree is an open question. Well, like I said, legal use is not defined, so you likely would be ok (it boils down to, does the cop think you have it for reasons of B&E, if so, you are in violation of the law, if not, you are good to go... NJ also has a similar law on knives... there is actually no definition of how long of a blade is illegal to carry, it all has to do with intended use... technically, if I had a valid reason, I could strap a 3 foot long sword to my side and walk around with it... on the other hand, if I have a box cutter in my pocket for no valid reason, I can be arrested... mind you I've carried a pocket knife every day for most of my life, and I've never been so much as questioned about it... that includes the two times I was removed from my car at gun point and then searched) >> (It is also illegal to have a police scanner in your car, > >Contradicted by the Communications Act of 1934, which being Federal >law should override it. I know if a few people that have gotten in hot water for having police scanners in their car. Mind you, it is ONLY in their car (although portable may be covered as well). Having them in your house is just fine. >Now I'm baffled. I can see reasons for banning lock picks and police >scanners, even though I vehemently disagree with those reasons. But >why on earth should center punches be illegal? I don't carry one >routinely, but if I'm going somewhere that I expect to need one, >I carry it. The idea is, a center punch is a rapid access tool for quietly and cleaning taking out a car window. So it becomes a B&E tool... much like your bolt cutters. (I actually carry a center punch in my car specificially TO break car windows... it is in my med kit that I carry in my trunk, and I've had to use it a few times when I've come across car accidents). But again, these things really boil down to can you convince the cop you have a valid reason for having them. If not, can you convince a judge. Anyone that has anything but an invalid reason, really shouldn't be worried. Those that plan to use them for illegal purposes tend to be pretty obvious (I don't know of anyone that has been harrassed over having the items EXCEPT for people that really were using them for nefarious reasons... I know of a few people that were questioned on them, and I know of a bunch of people that the items are ignored, because they have obvous legit reasons... just about all my friends have police scanners in their cars... but just about all my friends are in emergency services or law enforcement). -chris <http://www.mythtech.net>
