Back up 9 Track to CD

by compoobah＠valleyimplants.com

Depending on what you're doing, it might be good to do two copies: an image and a set of extracted or semi-extracted files. On the QIC front, Apollo wbak tapes and SGI "inst" tapes come to mind: if you copy off files using e.g. dd, you must write them back to a tape before you can use them (format is proprietary and uses head and tail files). If you distcp or rbak them off as files also, you have more options (you can either write a tape or set up some sort of network install system). Std tar and cpio files don't have this issue, I'm not sure about 1/2" systems. Scott Quinn

Free heavy duty web/ftp hosting for classiccmp'ers

by jwest＠classiccmp.org

As the old timers will no doubt recall, this is old news and they've heard it before. Newer list members may benefit and I haven't posted this for a while, so here goes. I try to post this about once a year. Among other things, I still own an ISP based in St. Louis, MO. We are a webhosting/colocation firm primarily but we also provide a lot of local access (dialup, T1, T3, xDSL, etc). This is not an operation run out of my basement, we have a real datacenter, FM220 suppression, biometric access controls, 30min online room ups as well as 7.5gw of diesel power backup, and some fairly serious bandwidth. What does this mean for classicmp'ers... well, basically - if you need or want, I will host any classicc computer related website or ftp site, free of charge. I'll also provide DNS services, email, mailing lists, etc. free of charge. Unlimited bandwidth (well, ok, there are some sanity checks if you pull half the sonet connection bandwidth and start to interfere with my paying customers). Why? Because it's something I can give back to the community since I don't have the electronics advice to give the list of the caliber of say.. Tony Duel :) You'd still maintain your site, it'd just be on one of our servers. Is there a catch? Yes. I will only provide free services for clearly classic computer related material. Do NOT ask me to host a website for pictures of your house, your dog, your company, etc... well.. unless you are prepared to pay going market rates - then I'd be all ears. But for any classiccmp related website, there is no charge, ever. It's (I think) a sweet deal, because you'd get your site in a world class datacenter with some stellar reliability - at no cost to you. Because I own the company, you don't have to worry about some friend hosting your site and then suddenly saying 6 months later "dude, I got a new job, can't host that site). If anyone has a need for this, just drop me a note off-list. Jay West

TSX sources, distribution, etc.

How > about sending or putting online for download exactly what you received? > Isn't that what you told the author at S&H what you were going to do? The source listings are already up on bitsavers - and one of my DCL (DEC Computer Lunch) buddies here in SV has written a special OCR program that is scanning the listings to re-create the original MACRO sources of TSX. So there's plenty going on (no commitments on that totally happening, timing, etc.). > This is ridiculous. Should I approach S&H myself, on behalf of all of the > other interested parties? "Ridiculous" is in the mind of the beholder. Yes, I could have taken the time to put up the TSX website as opposed to obtaining every RL02 pack and SMD drive I could from S&H, preserving the contents, etc. But I figured that "exercise", which took weeks of my time was more important than "releasing" TSX code. I'm required under my agreement with S&H to have a website where I can "log" and "verify" to a reasonable extent that only hobbiests will be downloading the system, etc. I am committed to getting TSX into the hands of the "folks" - but I estimate that it will take a week or so of my time - contiguous - to do it. That hasn't happened yet - but I promise it will. Regards, Lyle -- Lyle Bickley Bickley Consulting West Inc. Mountain View, CA http://bickleywest.com "Black holes are where God is dividing by zero"

Back up 9 Track to CD

by steerex＠mindspring.com

Hey guys, I've got a bunch of old 9 track tapes, including bootable tapes for a variety of systems, that I'd like to "backup". The tapes vary from MPE install, HPUX install, and misc DATA tapes (multiple formats). Some of the tapes are pretty old and I really need to archive them. I think CD's are gonna be around for a while so, that seems to be the most reasonable medium. I know, I know... CD's don't last forever. That's a different topic and not something I can worry about right now. I've also got a pile of spare 9GB HD's. I suppose I could dump the images there as well. With multiple copy's on CD and on HD's. The data should be safe. There is a 9 track attached to my HPUX 10.20 box so, reading and writing the tapes is no problem. The HPUX box does not have a CD burner directly attached although, I can FTP files to a WINDOWS box and burn CD's there. So the question is: Can I just DD the tapes to a file and stick the file on CD/HD then recreate the tape from the CD when needed? NOTE: Some of the tapes span multiple volumes. Is this gonna be a problem. TIA, SteveRob

Help ID oddball SCSI controller

Has three AIC-7880's on it connected to >External connector appears to be LVD or SE (bummer, I >was hoping to find a HVD in this box of goodies...) > >I'll assume it's a RAID controller. I don't know anything about any RAID features, but the AIC-7880 supports Ultra-Wide SCSI, but not LVD. So assuming the firmware also supports it, you should have UW and earlier support on that card. The 7880 is the chip used on the Adaptec 2940UW and the 3940UW, but the 3940UW is just a DEC PCI-PCI bridge with two 7880 chips hanging off of it--basically two 2940UWs on the same card with a PPB to make it fit in one PCI slot. Some of the very late model Adaptec 2940UWs used a later chip (such as the Dual and the Pro models) but the vast bulk of the 2940UWs used the 7880. Jeff Walther

I too just got a "new" DECmate/VT278. I?m a half-step ahead of Richard in that I have a set of RX02's to go with it but the donor hasn't yet been able to locate the software that he's sure he still has "somewhere". I've downloaded some telnet images of OS/278 but I don't have a PC running 8" drives to use to create the disks. Can anyone help by providing a physical copy of an RX02 OS/278 boot floppy? Please contact me directly if you can send a disk. In the meantime, if the docs remain elusive, I'll be glad to ring out my VT278 - RX78 cable. best, Jack -- No virus found in this outgoing message.

The official VCF East 3.0 press release...

by evan＠snarc.net

Please spread this far and wide! -------------------------------------------- *** Vintage Computer Festival East 3.0 -- Saturday, May 13 -- Wall Township, N.J. *** April 17, 2005 -- Wall Township, N.J. -- The Vintage Computer Festival is coming! For those who fondly remember the charisma of computers from the 1960s, 1970s, and 1980s, this is a must-attend event!! "VCF" as it's known in computer circles is an annual public convention devoted to the enjoyment and restoration of antique computers. The show began in Silicon Valley in 1997 and the current edition is VCF East 3.0. At this year's VCF you will find 17 exhibits of functioning antique computers, six high-profile guest speakers, exciting prizes, and kinship with hundreds of fellow early adopters. Spend a few hours at this event and you'll be in nerd heaven! There will be dozens of antique computers on display from the glory days of blinkenlights, tape drives, greenbar paper, punched cards, homebrew kits, text-adventure games, and much, much more -- and no Windows in sight. Like we said, it's nerd heaven! Use the day to learn, play, or just reminisce with us. So mark Saturday, May 13 on your calendar. VCF East 3.0 will be held at the (new!) Information Age Science and History Education Center, a.k.a. "InfoAge," which was formerly the Camp Evans U.S. Army base and was originally built for the Marconi corporation in the early 1900s. The show's hours are 9:30AM - 6:30PM. Tickets are $10 per person ($7 for children 13 and younger) and parking is free. The address is 2201 Marconi Rd., Wall (Belmar), N.J. and driving directions are posted at http://www.vintage.org/2006/east/directions.php VCF East 3.0's sponsor is the Mid-Atlantic Retro Computing Hobbyists Inc., which is a non-profit user group devoted to antique computing. MARCH is also building a computer museum at the InfoAge facility, where there are also museums dedicated to antique radio, model trains, historic shipwrecks, antique military vehicles, and much more. The museums opened this month in a preview facility and the full museums will debut gradually throughout 2006-2007. *** The exhibits *** There are 17 registered exhibits for VCF East 3.0. The exhibitors are: -- Vince Briel, North Ridgeville, Ohio. Vince will show his newest replica kit, called the AltairPC, based on the famous MITS Altair computers of the mid-1970s. This kit follows his hugely successful Apple 1 replica. -- Rich Cini, Syosset, New York. Rich will show his own Altair replica, called the Altair32, which blends an emulator project and front panel kit. -- Bill Degnan, Landenberg, Pennsylvani. Bill will highlight his exclusive collection of Commodore B Series computer which were never produced. -- Mark Dodel, Stroudsberg, Pennsylvania: Mark will bring his thorough collection of IBM OS/2 computers including some very rare models. -- David Gesswein, Bethesda, Maryland.

Beeps on power-up. Shows a cursor in the upper LH corner and status line bar across the bottom. No screen burn. It has the key for the base keyboard lock. 3. 3192 base less monitor and keyboard. Powers up the same as #2 above using that monitor. No key. 4. 3191 logic board, IBM part number 6456289. Appears to work the same as #3 above. If you are interested in any or all of this let me know and I'll box it up and ascertain the shipping cost(s). I'll need your shipping address also. Regards, Bill

Useddec@aol.com

by Useddec＠aol.com

Hi John, Well, I try to be useful. I have replied to both technical and historical inquiries both on and off list. I worked in field service for DEC for several years and had to leave because of health reasons. I've dealt with used DEC parts for a number of years, but am again having health problems. I would much rather give phone support (which I often offer on my dime) than on line support because of neurological problems that make it slow and difficult to type. I am interested in this field, and enjoy sharing my somewhat limited knowledge with people weather they are customers or not. I do not have a web site, but have recently started an E-bay store, and am located in Illinois. I have mostly DEC and DEC compatible parts and lots of them. If I can answer any other questions, feel free to ask. Thanks, Paul Anderson

Altair Floppy Questions

by eric＠rothfus.com

A couple Altair questions: Question 1 - has anyone seen/created an adapter for the 37-pin d-sub connector for the Altair floppy drive to the later standard 5.25" floppy interface. I use the term "standard" rather loosely, but am refering to the 34-pin connector used by the TRS-80, Heathkit, and numerous other machines of the late 70's. This "standard" with a couple changes became the PC's 5.25" interface. It doesn't look too tough, and I have a basic design in mind, by why re-invent the wheel if I don't have to? Question 2 - where can I find some blank hard-sectored 32-sector 8" floppies? Eric

IBM hercules setup pics

by jwest＠classiccmp.org

I thought I'd post a few pictures of my IBM emulation setup. While it's not complete, it is functioning. There is a PC box running unix with the hercules emulator on it. This box has RJ45 ethernet to wireless for the home network. Also a temporary PC monitor & keyboard (to be replaced with a rackmount 1U lcd/kbd unit soon as I can find one cheap). Of course, it's just not the same unless you're running a real IBM 3270 style terminal... so... the PC also has a token ring card that is connected to a 8223 MAU via type 1 cables. Also connected to the 8223 is an IBM 3174 establishment controller (dual floppies, 9mb ram, token ring - config C). Then connected to the 3174 is an IBM 3197 color display station. Yup, I know it's been done before, but I wanted to do it too :) I'm still working on the code that lets my real HP2000/Access TimeShared BASIC submit COBOL, FTN, BAL, PL/1, etc. jobs to the emulated IBM 370 setup and get it's output and/or datasets back to the HP. Fun stuff. I'm also going to try and set up a printer on the 3174 at some point as well. I had a nice rack picked out for this hercules setup, but decided on a different rack. Next step is to get all the stuff you see in the pics rackmounted along with 1/2 tape drive & add SCSI controller to the herc PC. Anyways, pictures can be seen at : http://www.ezwind.net/jwest/ibm/ MOST of the pics are clear this time :) Jay

Awesome ARPAnet documentary

by toresbe＠ifi.uio.no

Was surfing the web when I came across this documentary on ARPAnet - features some of the founders, including Davies, Licklider, Heart, and Khan. http://xrl.us/kg7y is a redirect to the download - it's on Google Video - this is an AVI file. Cute sightings include a PDP-10, and several seconds of a PDP-10 doing what appears to be a host list dump, with machines like MIT-AI and MIT-MULTICS appearing. If it was alphabetical, and all-inclusive, this documentary was made before 1973, as the NORSAR TIP wasn't on the list. -toresbe :)

ADDS Mentor 2000 - Big success!

by dave06a＠dunfield.com

Ok - so this particular system wasn't all that secure! Armed with the info that Jim told me regarding 'END' being "return to the command prompt" (I had previously thought it ment "end debugger and continue where you left off") ... I did this: - Logged into the BACKUP account - got to the menu of backup commands. - Hit BREAK - Got me to the '!' debugger prompt. - Entered 'END' - Got me to the '>' TCL prompt - Tried LISTVERBS ... This list was much larger than the one I got from GAMES ... Nearly 300 commands. Many of them look "systemish" - I'm guessing at this point that BACKUP may be a privileged account - makes sense since it would need to access "everything" in order to back it up) - Noticed that one of the commands listed is: PASSWORD - Typed: PASSWORD System responded with 'Account name?' - Typed: SYSPROG System responded with 'New password?' :-) - Typed 'DAVE' And returned to the TCL prompt. .. Sure enough, I can now logon to SYSPROG with the password 'DAVE'. Yee - Haw! Next step is to see if I can backup the system... Some Q's: (Keep in mind that I have very little actual info on Pick system administration and commands - please be verbose): - What is the best way to backup the entire system so that it can be restored? - From what I have determined, this system can boot from tape ... Is there a way to make a backup that is "bootable" (ie: I can boot from the tape and restore the system). If not, how can I make a bootable tape that can be used to restore another backup. [As you might guess, what I am trying to accomplish is to insure that the system can restored in the event of a catastrophic failure (either hard-drive or me screwing something up beyond a functional state). - Do I need to "format" tapes before using them? - Is there a way to write to and verify (ie: test) the tape system? - Other suggestions/advice welcomed.

Programming 2708 (1k x 8)

by eric＠rothfus.com

I was somewhat shocked to find out that my TopMax EPROM programmer doesn't handle the vintage 2708 1k x 8 EPROM. A very interesting little EPROM the 2708. It requires +5, -5, and 12v. Anyway, any advice out there for working with these old little beasties? I'd like to first read one, but eventually program them. Or maybe I should program the 2716 and substitute them (with appropriate bent-up pins)? Maybe, too, I could read them after telling my TopMax it is a 2716 and (again) bending up a few pins, or maybe using a pulled-pin socket. The 2708's are found in an S100 EPROM card in my newly acquired Altair. Eric

Ancient led message display with R6502

by roosmcd＠dds.nl

Anybody ever seen one of these before? http://img148.imageshack.us/img148/1102/041500219xn.jpg http://img221.imageshack.us/img221/2051/041500256wc.jpg http://img523.imageshack.us/img523/6451/041500242dq.jpg This is a LED message display controlled by a R6502-11 microcontroller board. The keyboard is from a Cosmac ELF, modified to run on power supplied from the uC board. Connectors are a bit flakey, seems to work but for the input. Unfortunately it's an ASCII keyboard connection, while I was hoping for it to be just rs232. Unfortunately this makes it a bit difficult to use for my application, unless I replace the board with a more modern microcontroller. Still doubting what to do about that a bit. greetings, Michiel

Dayton Hamvention, May 19 - May 21

by marvin＠rain.org

At this point, I don't know what the space numbers are, but I'll post them as soon as I know. If we have enough interest, maybe we can set up a dinner either Friday or Saturday night. I have some classic computer related (heavier) stuff here that some people on the list were (are?) interested in, and I can bring that stuff and meet at the Hamvention. I *really* dislike packing up heavier things, and some of it is almost not worth the price of shipping. I can post some of the stuff to VCM (http://www.vintagecomputermarketplace.com/) and just bring it with me to save on shipping (AND my great dislike of packing larger, heavier things.) OT - If anyone is into ARDF, there may be an event at Dayton again. The first time I was there (1999), I (along with several others) gave a talk at the foxhunting forum on ARDF and what it was like to "compete" at the world championships. And after the talk, most of my time was spent checking out the fabulous parking lot vendors ... I was in heaven :). > > Just curious, is anyone on the list going to the Dayton Hamvention?

PDP 11/34 available in UK (Essex)

by andyh＠andyh-rayleigh.freeserve.co.uk

I'm having reluctantly to admit to myself that I am not going to find the time to do something with the PDP 11/34 and pair of RL01 drives that have been sitting in my garage for far too long (18 months). There are also about a dozen disk packs that supposedly have various versions of RT, RSX, and Coherent on them and some manuals. If you are interested in making a reasonable+ offer for part or all of this please email me. In theory this is a collection only* offer but I may be able to deliver within, say 50, miles for the cost of the petrol at about 25 mpg. Longer deliveries may be possible depending on location. * Location is within 8 miles of Southend-on-Sea in Essex. + On eBay I believe I could get well over ?100, but probably not as much as ?200. Possibly even better if I split the manuals off and sold them separately. I have never powered any part of this on - the disk packs and drives should certainly be properly cleaned before use and the precautions repeatedly emphasised on this list should be taken before powering-on. The arm of the breaker switch on the back of the processor has broken so this will probably need replacing. I have some other items of DEC and SUN (Sparc 5/10/20, Ultra 30) equipment and a desktop HP Unix workstation that may be of interest. Andy

Old IBM PC/XT stuff available (free)

by bobalan＠sbcglobal.net

I thought I'd make this stuff available before I send it off the the recyclers. I really don't want to ship it, it's just not worth the time, but I can deliver to the Silicon Valley area or it can be picked up at my home in Santa Cruz. Three IBM 5154 EGA type color monitors. Three IBM 5151 Monochrome monitors. PS2-30 with keyboard. Three XT chassis missing the hard and floppy drives but complete otherwise (motherboard, power supply, some I/O cards etc.) Packard Bell XT type system with color monitor and keyboard. This boots up and I can do a directory on the hard disk. I did not try out the other stuff but it all came from the Dovebid Telogy auction and so far everything I did test worked. There may be more monitors and another system or two after I get them all sorted out. If anyone wants any of it, please let me know soon, I really need the space! Bob

ADDS Mentor 2000 - A little more success/info

by dave06a＠dunfield.com

Hi Guys, Found a couple of docs on the net which proved useful. One "A guide to the pick operating system" - a very brief summary of the system, and gives a few commands... 2nd was a "hackers guide", which gave a list of common accounts ... So I tried them on my system, and here is what I found: COLDSTART SUPPORT - These exist, but have unknown passwords ACC BLOCK-CONVERT SYSTEM-ERRORS - These exist, have no passwords, and drop you into a '>' prompt, however it appears to have NO commands. No matter what I try, I get: ERRMSG [ERRMSG] 3 ERRMSG - As above, except that the message I get is: [3] What was that? -- Now to the more interesting ones -- BACKUP - Exists, no password, launches a tape backup menu. It appears that I can do a backup of the system to tape from here. GAMES - Exists, no password, launches a menu of games you can play (there's quite a few).With the option "Press NL to exit" Hitting return (blank line) drops you to the '>' prompt, however this appears to be a fully functional TCL shell. You can do WHO, WHAT, WHERE etc. I found LISTVERBS and it shows 147 commands. Haven't tried, but looks like I can format and manipulate tapes from here. Also looks like I've got BASIC, and EDITor - there's a COMPILE command, but I have no idea what for... Lots of others. Btw - Hitting BREAK in any of the above accounts once logged in does get you to the '!' debugger - END resumes.

What kind of computer was it? Do you have any pictures or online references to one? Technically, Tandy/radio Shack did not swich to the "Tandy" name on the II/12/16/16b/6000 line until the 6000. I currently have at least 6 16b computers, and they are all labeled "TRS-80". I have 4 6000 computers and they are all labled "Tandy" However, they are essentially identical machines with a slightly faster clock speed in the 6000, and two PAL upgrades. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org]On Behalf Of > Alwrcker82 at wmconnect.com > Sent: Saturday, April 15, 2006 1:15 PM > To: cctalk at classiccmp.org > Subject: Re: Tandy Model 16b computers availabe > > > Hi there is a Tandy 16b, not a TRS-80 16b. and I would like > the one you have > with the 8" drive, when is a good time for me to come, > weekends are best for > me but I will work with you.

Thanks to all: 8820 now working

by kyrrin＠bluefeathertech.com

My thanks to all who offered assistance on my issues with the 'tech special' Trak Systems 8820 GPS station clock. The unit was successfully repaired, and has been working for nearly a full week without any further signs of problems. For the curious: The problem turned out to be that one of the firmware EPROMs developed a broken internal bond wire on the output-enable lead. This caused the chip to appear completely blank to both the Unisite programmer and the Trak device. My contact at Trak was kind enough to send over image files to do a fresh set of EPROMs. The only other adjustment I found myself making was a fine-tune alignment on the 10MHz ovenized oscillator, to bring its center frequency back to a point where the reference circuitry could discipline it down to full accuracy. That was also accomplished without incident, and I now have a second Stratum-1 level clock and frequency standard for my lab. The moral of the story: EPROMs can fail too! Just not in the way we might expect. ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

someone else with an adds mentor 2000

by aek＠bitsavers.org

at least as of 2003.. maybe he turned up some docs http://www.digibarn.com/weblog/blogger1.html From Eddie Thomas (pasnocone at earthlink.net) Gentlemen: I?ve been a hobbyist/engineer of PC systems since I can remember. I was introduced to computers in 1974. I?ve designed one 8086 system for the S-100 during the winter of 81/82 of which never made production. At that time I also laid out the concept of CABLE MODEMS for mass bi-directional public communications. The idea was too far fetched to be seriously taken into production back then. It?s amazing how things change ? 20 years later! I enjoyed your documentation on the ALTAIR 8800. I stumbled upon your site as I searched for S-100 prototyping boards. Although I currently live in PA, I believe I have the original schematics published in Popular Electronics (Jan ?75) for the ALTAIR stashed in the attic in NJ. I also believe I have most of the Popular Electronics issues which addressed the S-100 based systems. I have not found any other rags that have this information available. I?d be happy to forward the articles if you?d like. I will contact P.E. in regards to duplicating this info as to not violate copyright laws. S-100 was onto something before Big Blue stomped S-100 like a New York City roach. Here's a question. I am currently searching for information for the ADDS Mentor 2000. It uses the Zilog 8001 segmented processor under the PICK OS. I have no background in PICK OS. So far the only confirmed operation is the POST. MENTOR 2000 specific manuals would be greatly appreciated. PICK OS manuals or souces to gain some tech knowledge into the workings would also be appreciated. Trying some DOS and CP-M style commands yielded this: The machine attempts and fails to find a TAPE DRIVE and HARD DRIVE. The tape drive interface card is inoperative [installing it stops the POST]. The original 68 Meg H/D (Hitachi 511-8, ST-502 MFM) was reused years ago in a Netware Server. I am looking for hardware manuals specifically detailing hardware interface characteristics and/or this system's bus. I can engineer a compatible ISA interface for bi- directional communications to my Intel 302-25 PC if I can find the BUS pinouts. The Zilog 8000 series is similar to the Z80 in timing characteristics for BUS I/O operations. In the event I can finally gain external I/O to this system I've located several OS's for the Zilog 8000 family, of which some re- writes will be required to gain full system functionality. It's apparent the OS is in two EPROMs, of which will be preserved. It is my intention to engineer an updated I/O card to support Floppy disks, IDE hard drives, newer memory products and Ethernet. AT&T originally supported the ADDS systems. NCR (AT&T?s sellout company) would supply information as would some scarce sources for an exuberant price. ALSO I would like to find information on the WD-1002 HDO hard drive controller card (used in the TANDY PC, I believe) Specifically, I need cable signaling information so possibly to use an IDE translator adaptor. I've found one source but have not heard back from them in about 6 weeks. Here?s a list of what hardware is installed (original): 1: CPU Card Zilog Z8001 w/socket for 2nd processor (4 layer) a) ADMIN Serial Port header b) TWO WD-1002 interface port headers c) Front Panel Control header 2: 16 RS-232 serial / 1 parallel port (4 layer) a) Two 50 pin headers (to 2 banks of 8 9-pin serial ports on rear) b) One parallel port header 3: 256K memory card Parity Checked (4 layer) a) 4 banks of 9 4164?s 4: 3 port QIC-02 tape interface (defective) (2 layer, EZ 2 trace/repair) 5: Hitachi 511-8 68 MB H/D w/WD-1002-1 HDO daughter card 6: Archive 60 MB Tape Drive, Full height (defective) Although the ADDS Mentor BUS is 100 pin, it is quite obvious it is NOT S-100 just by examining the power assignments. I am currently diagnosing the TAPE DRIVE interface card hopefully have it back in operation soon. I have a newer Archive QIC-02 drive that should work. It can read/write 60, 120 and 250 MB tapes. Any information, sites and/or folks wishing to get involved w/my resurrection of the ADDS Mentor 2000 are welcome to contact me at: pasnocone at earthlink.net Please put ?Mentor 2000? in the subject line Best of luck and congratulations on a great start with the Museum!

From what I can find out it is a R 6000-39H or such vintage multi processor machine. Sale is May 6th, 10:00 AM, Preview at 8 am and also the day before on Friday May 5 from noon till 7 pm. I guess there will be online bidding via Proxibid (I just found this out myself). I used to travel to the Uof W auction regularly for the wide varietry of stuff. There is a regular Surplus property sale at the same time with a black box that could be a NEXT Cube. www.uwsurplus.com Click on Auction or Public Store. I can't make it so if anyone gets it let the list know -- Paxton Hoag Astoria, OR USA

Dayton Hamvention, May 19 - May 21

by marvin＠rain.org

Just curious, is anyone on the list going to the Dayton Hamvention? I bought two selling spots, one to park, the other for "stuff" :). My expectation is that I'll arrive sometime on Thursday, and of course make sure I am there *early* on Friday morning. Since I expect to be driving straight through (about 42 hours >from Santa Barbara, about 22 hours from Denver including gas and short rest breaks), if anyone is interested in sharing the driving and gas, let me know. My interest there is twofold, 1) find classic computer related stuff, and 2) sell ARDF (Amateur Radio Direction Finding) related stuff along with other "stuff" hams might be interested in. I also expect to take a pop-up canapy for *when* it rains. And if anyone going is not aware; the scroungers are out in full force on Sunday since many of the parking lot vendors just leave behind what they don't want. A friend of mine told me the story that he was out scrounging and another person came to the same spot to scrounge. A third person arrived, and looking through the stuff, asked how much a certain item was. The second person immediately started hawking the stuff :). Another story (I believe is true) is that first, parking is hard to find near Hara Arena. One ingenious soul took their car to the gas station across the street and dropped it off for an oil change. After a day at Hamvention, he then picked it up from the gas station for the price of an oil change :). You might have to have been there to realize that parking could be as far as 1/2 mile from the arena, farther if you park someplace where a shuttle would pick you up. Marvin, KE6HTS

IRIX 5.3 system: any access?

by compoobah＠valleyimplants.com

Linux EFS works fine on SGI disks, as long as you have SGI disklabel support compiled in, but it is read-only. XFS is read-write. The mount device is, as was said, dks[scsi disk](x)d(y)s(z) with x the SCSI bus number, d the SCSI id number, and z the slice number. The PROM is different, with SCSI drives represented as dksc(x,y,z). Other interfaces use diferent identifiers, like dkip. common slices are 0 (root), 7 (option disk, non-bootable second drive, also used for CD-ROMs), 10 (the volume partition), 1 (swap), 8 (volume header) and 4 (usr, not present on modern default disklabels). SASH (the Stand Alone SHell) is in the volume header and is instrumental in booting. The volume header is a small section of the disk that has a filesystem that can be understood by the PROM monitor. It contains the disklabel, symbolic monitor, IDE (interactive diagnostic environment) and SASH. The firmware bootstrap machines load SASH from the volheader (which the ROM understands) and then SASH loads IRIX from the main filesystem (which it understands) Really a cool system, you don't need anything to write a bootblock, and it is possible to load SASH from a CD-ROM and start the disk-resident copy of IRIX if your SASH is corrupted. dvhtool is the IRIX utility provided for writing/reading the volheader. SASH, however, needs to be the correct version to understand the filesystem (a 5.3 EFS SASH can't boot a 6.2 XFS partition) Since SASH understands the filesystem, you can use basic commands (cp, cat, ls, setenv), but no UNIX utilities like vi. If you could create an accessible replacement passwd, it could be copied over on top of the original passwd file [dksc(0,1,0)/etc/passwd]. You need to be very careful, especially with IRIX 5.3, to get a version that runs on your hardware. A big gotcha is with later machines that come with 2MB of cache (IRIX 5.3 base won't run on them) 6.2 is easier, there are only two versions, one for R10k Indigo2s and one for everyone else (the R10k I2 also supports all other I2s). It would be much easier if SGI had made later releases support all earlier machines, but they didn't. The 2MB cache issue can, in rumor, be sidestepped by installing base IRIX 5.3 using a 1MB cache CPU(PM1-PM5), applying all patches, and then plugging in the 2MB PM(6 or 7)

GE Terminet 200 - original Operators Manual available

by dave06a＠dunfield.com

Btw - when I picked up the TRS-80 and ADDS on the weekend, I was asked to browse a box of "stuff" in case I wanted any of it - most of it was older PeeCee stuff not interesting enough to reserve space for (or risk getting stuck with), however one of the items I did grab was an original General Electric TermiNet 200 PRINTER OPERATOR'S MANUAL GEK-49326B In very good shape - I don't have a TermiNet, however I recall that a few people on the list have them ... if you have one and want the original manual to go with it, let me know...

LSI-11/2 CPU with tracks cut?

by sb＠thebackend.de

Hi! I got a M7270 CPU module here from my PDP-11/03. It has the tracks to the QBus contacs BC1-BF1 (BDAL18, BDAL19, BDAL20, BDAL21) cut. I of course wondered why one would do that. In [2] I found the following hint: --- II. Restricted Compatibility Options Options in this category do not meet one or both of the requirements for use in a 22-bit system. These options are incompatible with some or all 22-bit systems. ... KD11-HA M7270 LSI-11/2 CPU (16-bit addressing only, and use of BC1,BD1, BE1,BF1 for purposes other than BDAL18-21) --- So I guess someone tried to make the CPU compatible with 18/22-bit modules? What did the M7270 use these pins for? I didn't find any manuals or schematics for the this CPU yet, only for the LSI-11. Could someone point me into the right direction?

Programmer's conundrums

by sdc695＠yahoo.com

Tony Duell says: > Yes, back when engineers actually thought about things and didn't attempt > to 'solve' problems by throwing computing power at them. > -tony I believe that one of the first lessons that should be taught is to program something (of a size greater than a "hello world" program) on an ASR33 or equivalent device. It is a VERY humbling experience. One actually learns to look at programs before executing a compile/run step and takes some thought before doing a "let's try this". I was also told about the firm that went to an automated payroll system. The first candidates (beta testers) were the programmers themselves. Having a built in incentive to "get it right" is VERY motivating. Everyone should keep an ASR33 floating around just to show others. An LA30 is an (almost) acceptable substitute. -- Tom Watson tsw at johana.com __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

ISA bus throughput

by mbbrutman-cctalk＠brutman.com

I revived an old 6Mhz PC AT today by removing the original Western Digital based hard disk controller and replacing it with a newer, generic IDE controller. The large boat-anchor class 5.25" full height hard disk had died, and without a suitable replacement a small IDE drive was chosen. The rest of the machine is original, including the EGA card with the extra memory daughterboard and the full slot monochrome card. While discussing this beast, the topic of putting a CD-ROM on it came up. (I would never do such a thing except for giggles.) The topic of the CD-ROM led to a throughput question - could this old monster even do it? As in, is the ISA bus up to reading from the CD-ROM at a reasonable speed? Well, let's go throught some quick math. 6 million clock cycles per second is a lot, but when you consider that each transation on the bus takes 4 to 5 cycles, and instructions take 4 to 5 cycles (average) on a 80285, the throughput might not be so hot. Forget the CD-ROM and let's just pretend it's an I/O device on the bus, like a fast hard disk. Given a PC AT running at 6Mhz, what can reasonably be expected for bus throughput? (Obviously this depends on the loop and the instructions used.) I would have guess 500K or so per second, but now I'm second guessing myself and I'll actually have to write a small benchmark to try it. When writing to a hard disk, would this machine have used a tight processor loop, or would it have used DMA? Under what circumstances would it use DMA to transfer data to a hard disk? And one last question .. Unlike the PC and XT, the AT BIOS handles hard drives. It didn't blink when I removed the crusty WD based controller and replaced it with a no-name WinBond based controller. Does the new IDE controller really look that much like the old controller that the BIOS can't tell? -Mike

Neat score today...

by kyrrin＠bluefeathertech.com

While poking around for some batteries and a coax adapter at one of the local electronics supply places, I came across (much to my utter surprise) a fairly clean Fluke 9010A micro-system troubleshooter plus two pods: One for the original Motorola 68000, the other for the 6809/6809E. I asked about it, and was told that it was open for offers. Taking a long shot, I said "would $50 be OK?" Less than a minute later, the answer was "You got it!" I've seen the pods alone go for over three times that on Greed-bay. However, I have no intention of putting this unit up for grabs. They're way too useful for working on older embedded-CPU gear. What really amazes me is that finding something like this was the farthest thing from my mind. I was going to go to the local Radio Shack instead of all the way across town, but a tiny mental nudge said "No, go to Tukwila instead." Once again, I've found that listening to one's "inner voice" can be greatly rewarding to one's test gear collection (if a bit hazardous to one's checkbook). ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

RL drive lubrication

Buroughs L5000 available

by dm561＠torfree.net

A fine machine; spent many happy hours programming these in my distant youth. Not much use without software however; alas, I threw out several boxes of manuals and PPT utilities & games years ago. I do still have a programming manual for it somewhere but, again, not much use without the assembler or at least the M/L monitor. I believe Bletchley has one of these; they might have some software for it. If you're talking about the built-in PPT reader beside the keyboard, that's only used for loading firmware and installing software; basic data I/O uses mag stripe ledger cards, and a small internal HD for RAM. They could have optional PPT I/O however; if you actually mean an external PPT reader (unlikely, since then it would presumably also have a perforator), that might be useful for someone to convert to a standard interface. I still have one or two in case anyone's interested, BTW. If you remove the innards and replace the top they do make sturdy desks or workbenches; at least two of my clients upgraded them that way. Some genealogy: Series F was the original ledger card posting machine; mechanical marvels of springs and levers, rotary accumulators & registers, full numeric keyboard, and a type bar printer, as seen in many banks & offices in the 50's. It was programmed via a removable rack of varying length metal pins; you picked your "op codes" out of a compartmented tray or box (or made your own with a sharp file) and "assembled" them into a program. Carriage movement literally "stepped" through the "program", and the location & length of the pins were the machine language (in the truest sense:) instructions. Parallel processing of a sort, since each program step had multiple instructions; i.e. you would read the keyboard, add & subtract the accumulator and up to 18 registers, and print, all in one operation. Series E added switches and solenoids and connected it to an external fridge-sized cabinet for calculations and core-based RAM; also added PPT and mag stripe card I/O. Except for carriage movement, the programming pins were replaced with "soft" code. L2000-L5000 consolidated it into a desk-sized unit with a PC style A/N keyboard, replaced the moving carriage printer with a dual tractor Selectric type ball, and core with a hard disk. L6000-L8000 replaced the mechanical keyboard & PPT loader with electronic ones, the hard disk with solid state RAM, and added optional cassette I/O & datacomm. L9000 replaced the Selectric ball with a dot matrix printer. B80 & B90 replaced the mag stripe cards with floppies and 5/10Mb fixed & removable HD cartridges and added a display. Since the ledger cards were gone, they then merged into the rest of the B series (B800 etc.) with separate terminals/keyboards and printers. mike -------------Original message: Date: Wed, 12 Apr 2006 18:13:13 -0500 From: "Dave Dunfield" <dave06a at dunfield.com> Subject: Buroughs L5000 available >I was in Montreal today picking up some goodies*, and the guy showed me >a Buroughs L5000 accounting machine - too big for me, but he would love >it to find a good home. >It's BIG - the size of a good sized desk.

HP TSB cards?

by Tim＠Rikers.org

Does anyone have cards that were used for HP TSB? I found an old printout of my text based 3D D&D program (circa 1980) that I'll be re-entering, but I've not found any of my old cards. The HP card reader (HP 2761A) would read both punched cards and penciled cards. We did not have a punch, so everything was done with a number 2 pencil. Our High School also used the HP-2114B system to grade tests taken on these cards. I seem to recall that they were printed in pink with black alignment marks, but I've used so many scantron cards since then, my memory may be cloudy. -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!

RL drive lubrication

by oldcpu＠rogerwilco.org

In a recent acquisition of several 11/23 systems I was fortunate to receive four RL01 drives, being two sets of Unit 0 and Unit 1. One set of these drives were very dirty/dusty, and by the looks of the course filters (which were deteriorating badly in all drives) and the accumulations in the power supply and plenum areas, I have to say this set was used in at least an ISO Class 10 Million level (not so) clean room environment! The other drive set was in pretty good condition, cleanliness wise. I replaced all four course filters, and checked the absolute filters, which were actually okay even in the dirty drives. Because all of these have been powered off for many years, I opened them up and pulled the power supply for a session with my capacitor reformation rig after cleanup. With that successfully accomplished, and finding that all voltages were in line, everything was reassembled. During the wait for the capacitors, I cleaned the interior pretty well with a vacuum and Windex. As a side note, three of the drives still had the platter brushes installed, and since I already had each drive opened for power supply checkout, I went ahead and removed the brush assemblies. Fortunately, the 'clean' set of drives are now fully functional, having been tested with one of the 11/23s. Unfortunately, after mounting and LOADing a known good disk cartridge, neither drive >from the 'dirty' set will show READY after spinup. Though the details are a bit different, each drive emits a very noticeable sound, kind of a whining/rumbling sound (not squealing), that I think is indicative of dry bearings in the spindle, the spindle motor, or both. I wonder if dragging bearings are preventing the drive from becoming READY due to uneven RPM? I've scoured the online documents for possible information regarding RL drive lubrication, but I can't come up with anything that suggests 'in the field' lubrication options. The RL01/RL02 Maintenance Guide talks about disassembly and Field Replaceable Units, but nothing about lubrication. So a few questions for those in the know: Could dragging bearings be the cause of no READY indication? Has anyone had any experience lubricating the appropriate assemblies in an RL drive? If so, what lubricant is recommended, where is it applied, and how? Removing the motor for lubrication is no problem, but I wonder if removing the spindle assembly would then necessitate a head alignment once it's back in place? I'm not sure I'm ready to go through that process just yet! Still, if I need to do it, I need to do it. Any advice is welcome. Assuming I can get this resolved, I'm in the market for a set of (2) RL connecting cables and a terminator. Anyone with some spares that they'd like an offer on, please contact me off-list. Thanks.

QIC drive bands

by compoobah＠valleyimplants.com

More in the interminable drive band discussion: Further investigation on a statistically insignificant sample shows a wide range of drive band lengths, and the band pulled from a newish tape annd used (successfully) in the old tapes was the longest. I am now wondering if the problem may have more to do with surface degradation and "glazing" lowering the friction between the drive belt and the tape. A possible test of this hypothesis would be to use "Rubber Renu" on an old tape band and see if the issue is resolved. Before I do that, I wanted to get some more input. I'm not sure of the composition of the drive bands, or whether "Rubber Renu" (main ingredient: Methyl Salicylate) would be injurous to the tapes in the small quantities that would remain on the band.

IBM 3380 and 3880 manuals

by brian＠quarterbyte.com

Hi Folks, Do any of you have any manuals, particularly maintenance manuals, for the IBM 3380 DASD and 3880 controller in your collection, that I would be able to borrow (or read on PDF) at point in the future? Norm Aleks and I have a few of these that we would like to spin up one of these days, but no docs for them. (I don't have the specific sub-model numbers at hand right now, unfortunately). There are a few docs up on ebay now, in Chile, un-bid upon, but the shipping will be way pricey. So, I figured we'd best ask around before paying 30 bucks per lot to ship these up from Santiago. Thanks Brian

Paper tape, again

by aw288＠osfn.org

I still have quite a few new rolls of 1 inch teletype paper tape. It would be neat to trade for new 80 column cards, but no takers! Anyway, I suppose I could sell rolls direct. These are the standard teletype rolls, about 9 inches in diameter, and fit very nicely in a 33. Ask off list, please... William Donzelli aw288 at osfn.org

Update At Computer History Museum

by Billy.Pettit＠wdc.com

I just noticed a lot of new photos and brochures posted at the computer history museum site. Look in both the text and still picture area. Some nice stuff, especially on the early (pre-1960) computers. Billy http://archive.computerhistory.org/resources/

Sun Type 4 keyboard problem, help needed

by fernande＠internet1.net

Hey All, I've got a Sun type 4 keyboard that I disassembled, cleaned and put back together. It doesn't work. I've cleaned plenty of computer parts before, so I doubt my washing/cleaning methods are at fault. Do any common mistakes exist for re-assembly of these keyboards? I suppose it could have been bad beforehand...... I've bought it as surplus, and have no history with it. Furthermore, the IPX I'm working with recognized it with only the small board connected, but with the small board unplugged >from the board with the key contacts. What do these keyboards use for a cable? I picked up what I think it the right cable from the same surplus shop I bought the keyboard. Thanks, Chad Fernandez Michigan, USA

DecWRL OM tool? binary recompilation?

by brad＠heeltoe.com

Just curious if anyone here knows anything about the "OM" tool which the folks at DECWRL produced. The web pages are gone now but they're still in google's cache. It's a tool which will analyze binary files and produce an intermediate RTL description which will allow you to retarget the code. (shew - that has to be at least slightly on topic :-) I'm fooling around with some old Alpha code and eyeing EM64T. Hand translation is tedious and error prone. I've been doing automatic translations from Alpha asm to C as a test, but I'm sure an RTL approach would be much better. -brad

IRIX 6.2 question

by compoobah＠valleyimplants.com

Bear with me here - I'm within 1 month of being on-topic. I have a odd swmgr/inst problem on my 6.2 machine. I've installed 6.2 base, the latest recommended/required tardist (Sept. '99), POSIX and Y2k. Now wenever I launch SWMGR, it complains "Syntax error in mach expression TARGOS >= 1274627340" I've figured out roughly what's going on (something doesn't like a certain software level identifier) but I'm not sure really what's going on or what to do about it. Does anyone else have this problem? USENET is silent - unusual on a SGI question. trailer question - has anyone tried extracting the dev_IRIX4 files from IDO5.3 and using them on IRIX 4.0.5? Haven't tried moving them over to DouglasIRIS yet (4.0.5/3.3.2 dualie), but I'm rolling the idea around. file indicates that they are the ecoff binaries . . . back and forth, I know - don't have much of an attention span, I guess. The CADDStation is still progressing, though.

xa 2.3.0 6502/C02/816 crossassembler

by spectre＠floodgap.com

After a very long time, xa 2.3.0 is released, the latest version of Andre Fachat's 6502 cross-assembler package for 6502, R65C02 and 65816. This version includes multiple bug fixes (particularly for @ casting to 24-bit in 65816 mode, proper warnings and management of forward-defined labels, last line w/o a new line now gets assembled correctly), some cleanup, and new man-based documentation. There are also various other custodial fixes documented in the unified ChangeLog. This should now be considered the sole supported version. In addition, xa will in the future be accompanied by dxa, its companion disassembler. This is a rudely hacked version of Marko Makela's d65 0.2.1 with some extra output features added, altered defaults, some repaired bugs and the ability to parse and understand xa-format label files. It does not yet support 65816 opcodes and probably has some other bugs, so it is a separate download so far. This will be (slowly) worked on and then eventually merged into the formal xa distribution. Both packages are in ANSI C and are available under GPL from http://www.floodgap.com/retrotech/xa/ Please report any bugs and my apologies for the long delay in getting this out. -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- /etc/motd: /earth is 98% full. please delete anyone you can. ---------------

Harris Micro-12

by bkotaska＠charter.net

I have here a Harris Micro-12 (HB-61000). This is a single board computer with keypad and display using the Harris version of the 6100 PDP-8 CPU. Unfortunately, it is non-functional (dead) at the present time. Scoping the CPU after reset leads me to believe the ROM might be bad. Anyone have any info on this system? I have a data sheet which indicates that it orignally shipped with very thorough documentation. Thanks, Bill

Black Box KVM

In a message dated 4/11/2006 7:41:14 P.M. Eastern Standard Time, teoz at neo.rr.com writes: I recently won a BlackBox KVM Model SW939a and was wondering if anybody had one of BlackBoxs old catalogs with information on this unit.

Thanks TZ ------------------ I've got the perfect answer for you. Call black box at ANY time and they'll help you. I have a 4port KVM from them and had some questions about it, but it was Saturday night. Anyway I called their support line, and shortly thereafter that night, a support guy called me! He was helpful and got all my questions answered. I was simply amazed at the topnotch support. If only every company could be like this.

Sun Graphics tower

by rborsuk＠colourfull.com

Hi All, Anyone have any interest in a Sun Graphics Tower 4/75GT. I guess this was the 3D Unit for a Sun Workstation (correct me if I'm wrong). This unit is free for the taking. Pickup welcomed (North of Detroit). The unit is kind of large and weighs over 50 lbs, shipping could be arranged but would be expensive. My zip is 48047 if you want to check rates. If I don't get any interest, it's going out in the trash. The unit has been in my garage for several, several, years. I'm not a Sun guy so I don't know much about it. Rob

Teletype ASR 33

by aw288＠osfn.org

A number of folks have requested images and details about the 33 I want to sell. Here it is: www.bestweb.net/~toober/images/TT33.jpg www.bestweb.net/~toober/images/TT33.1.jpg www.bestweb.net/~toober/images/TT33.2.jpg www.bestweb.net/~toober/images/TT33.3.jpg It needs a little attention, but not bad. It will probably want a lube job, but the motor and mechanism does turn freely by hands - no rough spots. I can drag this to Boulder, CO, Carlsbad, CA, and up to the Bay Area. If interested, please ask off list. Offers would be nice, as well. William Donzelli aw288 at osfn.org
