Closet cleaning - stuff available

by rcini＠optonline.net

All: I have a bunch of spare stuff laying around looking for a good home: * Compaq DLT-III 5/10gb drive in external case. Working. * Compaq DLT-IV 35/70gb drive in external case. Working. * Philips Velo 1 WinCE PC. Worked when last used several years ago. B&W. * Tandy 2000 case parts (top, bottom, front plastic case pieces). No drive or switch filler plates included. Kind of yellowed. * Tandy 2000 VM-1 monochrome monitor (works, spare). Kind of yellowed. * Tandy 2000 MS-DOS and BASIC document binders with manuals. Condition fair (intact but dirty). * Atari ST-1224 monitor. Bought to hack to use with the T2K until I found a real CM-1. I hope to get around $10 for each item except the Atari monitor which I hope to get $25 (same price I paid), plus shipping from 11791. Other reasonable offers/combinations considered. For those preferring to trade, I?m looking for early Compute! Magazines (issues prior to #22 but not 3, 8, or 9), a plastic case for my KIM-1, the software support disk for the Ampro LittleBoard/186, the Windows 1.03 driver disk for the Tandy 2000, or a working 5.25? floppy system with disk for my IMSAI. Please contact off-list if interested. Thanks.

Tube or not Tube

Hi Strangly enough I do have an EHT meter. It's a legacy of building my own colour TV when colour came to the UK in the 1970's.

DEC VT240 terminal

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Most of your deductions are correct. In 1983, the VT220 replaced the VT100 in text applications, with the VT240/VT241 used where remote graphics (ReGIS and Sixel) were required. So add a keyboard and monitor as per your deductions and an application generating ReGIS or Sixel output and there you have it. Rod Smallwood The DecCollector. -----Original Message----- From: cctech-bounces at classiccmp.org [mailto:cctech-bounces at classiccmp.org] On Behalf Of Tony Duell Sent: 22 August 2007 23:01 To: cctalk at classiccmp.org Subject: DEC VT240 terminal I've just bought the base unit (VS240) for a VT240 terminal on E-bay and know little about it (OK, I know it's a DEC graphics terminal). Perhaps somebody can enlightent me 1) One site i looked at said a VT240 is a monochrome unit, a VT241 is the colour version. Is the only difference the monitor? Can I use a colour monitor with my base unit? 2) On the back are obvious connectors for an RS232 port (DB25), current loop (8 pin mate-n-lock). There's a DE9 labelled 'PR', presumably a printer port, also RS232. A RJ11 keyboard socket, I assume an LK201 will work here (yes?). A BNC which seems ot be composite mono video. And a DA15 plug, also for a monitor. I assume a VR201 links here, or a V241 with the right cable. Also, can I connect the keybaord to, say, the back of the VR201, or do I have to use the RJ11 on the terminal itself? 3) How much is known about the insides? Of course I've taken it apart. It's really easy to get inside, just undo 2 screws on the bottom at the very front and remove the top cabinet shell (lift it up from the front). Then release 2 nylatch fasteners and lift up the metal screening cover. The PSU (a switch-mode unit) is inside the cover. Reach inside and unlug the PSU ribbon cable from the mainboard and remove the cover/PSU. The mainboard comes out by releasing 3 more nyl atch fasteners. On this board, there's an 8085, 2681 (dual serial chip), 8251 (USART, maybe used for the keybaord interface), 7220 (graphics chip) -- along with what seemms to be much the same circuitry as a Rainbow colour card, there are a couple of PALs, I've not checked to see if they're the same as the ones in the 'bow. Pletny of RAM and ROM, and some glue logic. And another 40 pin chip, DC310. For some reason this is saying 'processor' to me. Is it? -tony

Broken floppy disks

by javickers＠solutionengineers.com

Hi guys... I have a truly huge number of old 3.5" HD floppy disks which no longer work. Attempting to format them in DOS returns the largely unhelpful "Invalid media or Track 0 bad - disk unusable" error message. I'm guessing it's because these disks are old (pushing on for 20 years in some cases, and I'm fairly sure they're *all* over 10 years), and they've degraded over time, or the magnetic signals have become disorientated, or some such technical explanation.... However, the result is, they're so much plastic scrap at the moment. Is there any device/program/machine I can use to restore these floppys back to working order? I'm not overly bothered about keeping the data that's on many of them (although if there IS a way to preserve it, that'd be great), but they do still sometimes come in useful, and it'd be a shame to bin so many of them. Cheers! Ade. PS: Most of my old 5.25" disks, despite being up to 30 years old, are all working fine. Similarly, most of my old Sinclair microdrive cassettes, which are >20 years old, are also fine - at least, the ones where the little foam pad hasn't perished are. Similarly, many of the compact cassettes I have for various old 20+ year old home computers still work.... are 3.5" 1.44MB floppies just inherently useless? No virus found in this outgoing message.

Part of the reason for discharging the thing is to prevent lots of electrons moving anywhere too fast. Better they should go to ground too fast than through you too fast, but you'll bounce ground all over the machine that way, which could be tough on other parts of the electronics. The resistor makes it all happen slower. You probably miss out on hearing the "crack" that way, but it still is better.

Tektronix 4002 Terminal found

by Arno_1983＠gmx.de

Hello Listers, last week I acquired what seems to be a Tektronix 4002 terminal - at least that's what a sticker on the rear of the base says. The front bezel with the type designation was nowhere to be found - apart from that, the unit looks just like the one at http://www.science.uva.nl/museum/tek4002a.html The "screen" part was missing, but we located a display unit (obviously self-contained - this matches the description above) nearby which has aluminum mounting rails to fit the screw holes in the base of the terminal. It has a power inlet and a DB-25 connector carrying what I suppose to be "raw" deflection/control signals - this would match the connectors available at the back of the terminal base, apart from the fact that the power connector coming from the base is an IEC coupler and the inlet on the back of the display isn't (has a round PE pin - the P and N blades fit the IEC coupler). So far I have a few questions about this thing: -Is the display we found really the one that goes with the base? -What kind of cable do I need to connect the two? (http://www.science.uva.nl/museum/rampspoed.html shows how it looks, but what are the actual connections - 1:1 or something different? Perhaps even some coax or twisted pairs?) -Some of the slots in the backplane of the base unit are unpopulated. Is this normal? -and last but not least, are there any special pitfalls I should be on the lookout for when I finally go about powering the thing on? Will it probably need capacitor reforming beforehand? Thanks in advance, yours sincerely -- Arno Kletzander Hilfskraft Informatik Sammlung Erlangen www.iser.uni-erlangen.de Psssst!

Tube or not Tube

Thanks Ian All points noted. As somebody who worked for four years in a high voltage test lab I agree re precautions.

Typically, from something else. Like other terminals, 12" monochrome PC monitors, and portable black and white television sets. A lot of these tubes are interchangeable. I've run across some that aren't, but for the most part, with black and white tubes, if the base fits, the neck and deflection angle is the same, and the heater is the same voltage, it's a good chance it will work. > b) How do you fit it. #include <std_disclaimer.h> Carefully. :) You want to be sure to discharge the high voltage first (in both the terminal, and whatever you're stealing a tube from!). To do this, attach a length of wire to the metal shaft of a flat blade screwdriver, and ground the wire to the chassis of the terminal/whatever. Hold the insulated plastic handle of the screwdriver and slide it under the rubber suction cup of the picture tube, until you feel the metal clip inside. Typically, this will be accompanied by a *CRACK* as the high voltage discharges. (Although, it is possible that the HV dissapated earlier, depends on the terminal) Do this twice just to be sure. To remove the clip, peel up the rubber suction cup, and you'll see it's a hooked clip that fits into a hole in the tube. Squeeze the clip together and gently remove it. Obviously, you'll want to disconnect the other wires leading to the tube - the base socket, and the yoke connector. Disconnect the yoke at the board, and leave it on the tube as you remove it. Unbolt the tube from the frame, and pull it out, careful not to break the neck. Also watch out for ground leads. The new tube needs to physically fit and mount in the terminal. There are two basic types of picture tube - the tubes with ears that bolt to something, and the tubes without ears, that use a metal ring to hold them to whatever. (VT100's have ears, VT220's don't). Your replacement tube must be of the same type in order to fit. The yoke needs to stay with the terminal. This is the copper coil thing on the back of the tube. Loosen the screws that clamp it to the neck of the tube and carefully remove it. Remember what way is up. You'll need to move this to your new tube. Try to get it on straight - it controls deflection, and if it's on crooked, the picture will be crooked. It's easy to adjust later though. Reassemble terminal with new tube. Cross your fingers and hit the switch. If it works, adjust your yoke for a level picture (carefully, you don't want to zap yourself). Once the yoke is level, shut the terminal off and tighten the yoke so it won't move. > If anybody has tried it I would be pleased to hear how they got on. I have replaced the tubes in a couple things, and had pretty good luck. I replaced the tube in a VT100 with one from a PC monochrome monitor, and it works well. One time, I even swapped a worn out IBM monitor tube back into a television. It was the only TV ever with WordPerfect screen burn. And those long persistance phosphors make TV look really weird. I kept it around as a joke for a while - I said that it was a black and white TV I converted to color. (Green is a color). -Ian * Be careful messing with high voltage stuff! Keep one hand behind your back when discharging tubes, and be sure your discharge tool is properly grounded to the metal chassis of the device. There's several kV potentially stored in there. I don't believe there's enough in a terminal to kill you, but it'll hurt like hell. Best to be as careful as you can.

VAXstation 3100 FB problem

by toresbe＠ifi.uio.no

Hello, I've got a VAXstation 3100 (Thanks, Peter Coghlan!) that I recently acquired while on holiday in Ireland. There is a problem I'm having with it - the 8-plane colour display controller is giving me an error message on startup: ?? 4 00D0 0016.0052 When I run test 4 on the Chevron prompt I get: >>> test 4 4?.. 84 FAIL and when I try test 50 I get (...) ?? 8PLN 0016.0052 (...) Does anyone know what could be ailing my new toy? The machine will run perfectly using the mono adapter, though VMS 7.3 will crash hard when trying to access the device (starting the X server). Is there a list of these error messages, somewhere? Thanks, Tore

Possibly classic flight controller

by silent700＠gmail.com

I picked this up at a hamfest last week. It may be about 10 years old :) http://tinyurl.com/2vprxy I need to start the long search for info and to get it going. Anyone recognize it? It's made by NT Systems of Melbourne, FL, who appear to be gone. Ports of the back suggest it hooked to the PC keyboard port (AT-style DIN5,) but it could as easily have used a custom interface card. Other ports are: power, keyboard, RS232/Modem, DB25 for rudder pedals (marked "This is not a serial port,") There's no model number that I can find. The gauges are fake, but they are surrounded by membrane buttons. The yoke moves in and out on a hydraulic shaft. The only thing I've found so far via Google is a Flight Sim 98 DOS driver for some product of theirs, not necessarily that one. Next stop, the flight sim forums, but thought I'd start here. -- jht

I just happened to spot this on eBay while looking at something else. A VAX 4000-108, in other words a VAX that looks like a DEC Alpha PWS. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130141799752 ELI only wants $8.5k for it, while they will see you a nice DS20E dual 667Mhz system for $2.3k, even an ES45 with dual 1Ghz CPU's is cheaper. :^) At the same time this is the first photograph I've ever seen of one of these systems. Somewhere I have the golden egg describing it. Zane -- | Zane H.

Need a few TC511001C-12 RAM chips

by earl＠baugh.org

Anybody got a few TC511001C-12's laying around that I could trade/buy? I'm working on my Sun 3/110 and the drawer I thought would have some of these seems to be picked over... only found 256K RAM chips left... (not sure what the heck I'm saving those for, but at least they don't take up a lot of space 8-) ) Or if you know of a supplier... I don't need more than 36 (if I have to replace them all on the motherboard...) Thanks. Earl

NCR mini tower looking for info ???

by g-wright＠att.net

Hi, I have a couple of these and need some information. These are NCR mini tower servers with a 68000 cpu. Has a Qic type Cartridge tape and comm board with 8 TTY ports (all 15 pin) and 2 CPU ports (1 DB9 and 1 DB15). I believe that the system boots to the CPU port on the back and then goes to the tty00 port after it loads the OS. I can see what it is doing on the CPU port up to the drive test. It works the drive for a short time and then stops displaying anything. The manuals don't say anything about the console port or pin outs. I would guess they expect the system to be install by someone other than the end user. The system freezes on self test when it starts to read the hard drive Or it has switched over to the comm board and TTYxx ports. I would guess that the drive needs to be formatted and the OS reloaded. So does anyone have a boot tape and/or the serial pin outs both 9 and 15 pin for one of these. Thanks, Jerry g-wright at att.net

He looked startled and said what disk drive? He had used the system for 5 years, never turned it off. He didn't even know that there was a disk drive in it! Now there was a great disk drive.

Logic trainer finds

Vincent Slyngstad wrote: I have one of these, and the wires with the plugs are a problem. Mine came to me with only a few of these left, and I haven't been able to replace them.

I (and probably others who own one) would love to get some more of the wires, or at least a source for the tapered pins to make new wires. If the tapered pins were available, I suspect brass eyelets could be used for an inexpensive (and almost authentic) plug/connector scheme.

'nother odd drive

by rtellason＠verizon.net

We just got given a "Power Mac 7500 Series" system (is that topical in here?), my first mac. It has, among other things, an external box marked "Syquest" and one "disk" that apparently goes with that, marked 200MB. Anybody familiar with these? All of this stuff is new to me... Also got a couple of printers with this system, a LJ5 and some Epson inkjet, is there any reason I wouldn't be able to use these with any other hardware? I dunno if it coming with the mac makes a difference here or not. Wondering too if that system uses a standard VGA monitor, as that's one thing we _didn't_ get with it. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.

ESDI Magneto Optical Drive

by ian_primus＠yahoo.com

I was searching on eBay for ESDI stuff, and came across an ESDI MO drive. Now, this was listed by one of those listers with eight pages of terms and conditions, and one line of a really bad description. It is listed as ESDI in the title, and in the auction, but near the bottom, it's listed as SCSI. I really, really want this drive, and I want it ESDI. But I didn't want to buy this and have it be yet another old SCSI MO drive. So, I checked with the seller - they have a website complete with live chat. I won't post the chat transcript since it's pretty long, but basically the guy first tried to evade with "We don't offer technical help" and stuff to that effect. I was not aware that "Is it SCSI or ESDI" was such a complicated question. But, he eventually decided that it was SCSI - I believe he called the stock room. So, did they even make this drive in ESDI? -Ian

They all work well for me, I keep the drive clean and dust bunny free and problems are rare. I worked in a place that had a fair amount of dust and if I didn't clean out the 3.5" drives once every 4 months they would destroy media. It wasn't a media problem it was gritty dust getting in there. I must have over 400 3.5" floppies of both flavors (720/1.44) and all but 100 are recycled prior use media that never give trouble unless the drive was at fault (dust). One comment regarding PC fans. PCs suck air in and often that means through the floppy and other holes in the case and out through the fan. This tend to dirty up everything very badly. I have an older P166 (workhorse system) that I reversed the fan, added a second fan blowing in and put simple fine mesh screens on the outside of both. I get far better life out of CPU coolers, floppies and CDrom drives as a result. I've made this change on other machines with similar results. Allison

SOL Terminal Computer (Chassis)

by dave06a＠dunfield.com

Hi Guys, Had a partially built "SOL Terminal Computer" dropped off here yesterday, all the important stuff seems to be here except for some parts of the chassis. Fortunately I did get two very full binders of documentation which has all the parts and assemblies listed. According to the docs, the chassis consists of: 1. Main chassis 2. EXpansion Chassis 3. Power supply subchassis 4. Fan closure plate [X] 5. Power supply subchassis bracket [?] 6. Keyboard bracket [?] 7. Left side piece, Walnut [X] 8. Left side piece, Masonite [X] 9. Right side piece, Walnut [X] 10. Right side piece, Masonite [X] 11. Keyboard cover 12. Top cover 13. Finger wall label [X] 14. Printed trim plate, Paper [X] 15. Plexiglass strip [X] 16. Serial number label [X] 17. Connector identification label [X] [X] marks parts that I definately have [?] marks parts that I may have (There's a bag of assorted bits - I havn't gone through it yet). As you can see, the big things that I am missing are the Main, Expansion and Power supply chassis, and the covers. It'd be great if someone responded with "I've got an empty SOL chassis" ... (anyone got one?) - but I'm never that lucky, so I'm expecting that I'm going to have to fabricate the missing chassis parts. Is there anyone on the list with a SOL who would be willing to take some defailed photos and measurements to assist me ?

Sun 3/110 memory issue

by earl＠baugh.org

Howdy, I finally got down to FL for long planned rescue of some Sun VME stuff... (BTW, I'll be posting some VME boards available in the next day or so, FYI...) and in the rescue I got a Sun 3/110 CPU board (Hurrah!... what I've been looking for a long time ) and even a 4/110 CPU board which I think I'll build out too. However, I've got a memory issue with the 3/110... I get the following output on the console with diag enabled: PROM Checksum Test DVMA Reg Test Context Reg Test Segment Map Wr/Rd Test Segment Map Address Test Page Map Test Memory Path Data Test Err 2: Addr 0x00000400, Exp 0x00000001, Obs 0x00010001, Xor 0x00010000 Can anybody tell me how to determine what bank this is on the 3/110 board, so I can replace the chip? They all look socketed and I've got a drawer full of RAM that I can swap out, if I can figure out the chip... BTW, when I jumper J3100 it cycles in both diag and normal, even with another memory board in... does anybody know if the 3/110 would boot with it's on-board memory disabled? Thanks. (cross posted to rescue list as well) Earl

Odd QIC-like tape

by ard＠p850ug1.demon.co.uk

A few days ago somebody here was asking about a QIC-like drive that didn't have optioncal BOT/EOT sensors, and wondered what tapes it used. Yesterday I obtained a car-load of HP150-related stuff. And amongst it was a pair of HP tape drive,s the 9144 and 9145, which use special HP pre-formatted tapes. Those had come to mind when I read the first posting, but I thought the tape was an HP 'special' so not relevant to the OP's machine But while looking at theAustralian museum (http://www.hpmuseum.net/), I found a link to a site that impliex these tapes were standard 3M products of the time ,the format was not custom HP, etc. The OP might want to look at that site and follow the links for 'storage', 'magnetic tape' and 'HP9144' (or 'HP9145'). I think that will turn up a like or twon that will be helpful -tony

OT-ish : HPCC Conference in October

by ard＠p850ug1.demon.co.uk

This is somewhat off-topic as it's not a totally classic-computer event, but there should be at least one old-ish (1970's) piece of computing machinery there. There is an HPCC (Handheld and Portable Computer Club) Conference in London (Imperial College) on 13th/14th October this year. Details are on the HPCC website (http://www.hpcc.org), there's an obvious link from the homepage. Attendance is free, and you don't have to be a member of HPCC. But you do have to register befroehand, we need to know how many are coming, and indeed who. Detials of how to do that are on the website too, don't e-mail me, OK :-) -tony

PERQ T2 faults

by julesrichardsonuk＠yahoo.co.uk

Am I right in thinking that code 010 on the LED display is "hung at disk boot"? If so, is there any way of getting a bit more detail as to the actual error at this stage? This machine has a 5.25" ST-506/412 drive in it. I don't think it's the one with the dreaded sticking rubber problem; at any rate I've had it spinning up on the bench - there seems to be a healthy clunk as heads unpark, and it doesn't spin down, suggesting that side of things is healthy. Other question: at the point when it's doing whatever checks yield the 010 code, should the display have initialised and be displaying anything? I'm getting nothing out of this system - but it's entirely possible that the display init is further down the boot process, and so it's never getting that far... (Anyone know which manual contains the pinouts for the video output and landscape display?) ta Jules

Lots of government funding for the 12 month program, so the classes were usually full. I believe there a couple of list members who took that class. The 1604 and 3000 cards both use +/- 20 volts, though on different pins. 1604 has power on pins 13,14 15; 3000 has power on pins 6, 7 and 8. So the mod was moving power pins. The signal levels could be mixed without level converters, though you stressed the 3000 inputs doing it. I only know of piece of equipment that actually mixed the logic families on the same chassis: The Digigraphics system. The power wires are always solid red, blue with black for ground. I may still have some of the documentation for it, but very uncertain. It's been a few years. However, Al has posted some of the CDI training manuals used with it. One is at CDC/modules/60238500_3000pcbs_Dec68.pdf. Billy

Searching for Ampro LittleBoard 186 diskette

by rcini＠optonline.net

All: I just received an Ampro LittleBoard/186. The manual I received with it makes note of the importance of the LittleBoard/186 PC-DOS Support Software Diskette (#A74012), which I do not have. It seems that there are some important programs on that disk which enhance compatibility with PC software and DOS 2.1x and 3.x. Does anyone have a copy of this disk that they can image for me? I will create a resources page for the LB, too. Thanks!

Logic trainer finds

by wdonzelli＠gmail.com

A double-header hamfest weekend yielded a couple of vintage digital logic trainer items. The first is one of those little wood boxes DEC Logic labs, but who cares about that. The more interesting thing is a book for the CDC logic trainer. From the pictures and writeups in the manual, this box has no logic of its own, but is made to accept a small number (20) of logic cards from a 1604. It mentions that it can be lightly modified to take 3000 series cards as well. Can Billy or Chuck add any comments? I have never seen or even heard of this box before. -- Will

Enigma Simulator for the Macintosh...

by alhartman＠yahoo.com

I'm hoping that this is on-topic for the list... Enigma Simulator - 1.1 simulator of the Enigma cipher machine with Steckerbrett Enigma Simulator is a program that simulates the use of Enigma ciphering machines that were commonly used by Nazi Germany during World War II. It enciphers text exactly the same as would a real Enigma machine. Now Enigma Simulator also includes the much anticipated Steckerbrett (plugboard). What's new in this version: -Steckerbrett (plugboard) -Universal Binary -Minor Visual Enhancements -'Reset' option added under 'Edit' menu (or use Command-R) -File Size Decrease (0.25MB off download and 1.2MB off Application file) -Minor spelling corrections http://www.versiontracker.com/dyn/moreinfo/macosx/32862 This software is for the Mac only. I suppose there must be a PC version out there as well... Enjoy! Al Phila, PA

MicroVax II/VMS - why 70mb isn't enough.

by ian_primus＠yahoo.com

Well, Sridhar and I spent yesterday doing some tinkering - I brought over my MicroVax II and we attempted to load VMS onto it. Easier said than done. By shuffleing parts around (and some considerable work getting ribbon cables through the bulkhead of a BA23), I was able to get a Microvax II configured with: Ethernet, ESDI w/ 70mb hard disk, and a TK50. I brought this Vax to Sridhar's house. The general consensus both here and on the netbsd list seems to be that the only way to boot/install a Vax is through MOP, over Ethernet. Well, now that I found Ethernet, it should have been simple. Sridhar has a Dec InfoServer 1000. This is a really cool little device the size of a CDROM player that can connect to a SCSI CD drive, and Ethernet, and be bootable by networked Vaxen. So, we cabled everything up, and immediately hit a snag. The InfoServer won't see the CDROM. In fact, it won't even boot right if there's a CD drive connected. We tried other CD drives, other cables, played with termination, everything. I discovered that the machine wouldn't boot if you just had a terminated cable plugged into it. The connectors are clearly labeled and keyed - no chance of mixing that up. A last ditch effort was to take a non-keyed cable, and purposely insert it backwards on one end. And it worked. So, if anyone is trying to connect a drive to an InfoServer 1000 using the 50 pin SCSI header on the InfoServer's board - that connector is BACKWARD! You must use a non-keyed cable and plug it in BACKWARD in order to make it work. After getting that going, and getting all the commands correct to boot the Vax off the InfoServer - all seemed well. Do the base restore set from the InfoServer, boot from the hard disk, follow the prompts and install the rest of the distribution. This is a 70mb ESDI disk, so after the base load, I had about 65000 blocks free. According to the installer, the Library, Help and DecNet phase IV will fit, just barely, with 300 blocks to spare. It won't. The installer runs out of space and crashes horribly. Reboot, reinstall base, back into installer, select only Library and DecNet IV. This leaves nearly 11000 free blocks according to the installer. This does not fit either, running out of disk during installation. At this point, it was 3:30 AM. We decided to call it a day (night?). Maybe I'll try NetBSD again. There has to be a way to get an OS onto a Vax in 70 megabytes. -Ian

I've had problems with the /f switch as well. For work with my Olivetti M20, I need a couple disk formatted as 320K disk. I've found that none of my formatting tools will reformat a 360K disk as a 320K disk. That is, unless I destroy the 360K format some how. Luckily, I've found that formatting on the M20 ( that puts FM on the first track ), is enough that the format tools think it has random data and will reformat to 320K if I ask for /f:320. I have used a magnet as well but I prefer to not use that method. Dwight _________________________________________________________________ Messenger Caf? ? open for fun 24/7.

The storage question

by silent700＠gmail.com

On 8/16/07, Mark Tapley <mtapley at swri.edu> wrote: > ...lots of good stuff... > >Any advice is appreciated! > > Heh. Sure hope you meant that literally; apologies if not. Indeed! And thanks to everyone for piping in on this. It's great to hear from so many on the subject. So far, I've distilled this: - The consensus does seem to be "no tapes or disks," which won't be a big problem for me as they don't take up much space and can be kept at home. I do have some boxed original software (CBM, Apple, etc) I'd like to store because of its bulk. I suppose I can extract the disks in most cases and take my chances with the shrink-wrapped stuff. - Paper will be a problem, as I had hoped to move a magazine collection there at least through the winter. It was suggested that allowing it to "breathe" is better than keeping it (and an amount of moisture) trapped inside plastic would be the better choice. Perhaps leaving them boxed but without plastic, plus a desiccant of some kind (a bag of silica gel in each box?) might do the job. - Concrete floors = dust and moisture. The storage facility itself is basically a garage - 10x15ft, about 9-10ft high with a large sliding door. The floor is heavily painted concrete (apparently thanks to the previous tenant as no others were like this.) I'm thinking a false floor constructed of bricks and plywood plus a plastic tarp might help keep the bottom items dry. - Things are going to rust. See moisture problems above. I guess it isn't unreasonable to wrap a uVax II in plastic with a bag of silica inside. - I'm going to abuse the newfound space and just get more crap until I can't move around my house. Quite likely. That will be a matter of willpower on my part. Thanks to Mark Tapley for a great rundown of his method of self-control. :) Despite the storage, I'm still going to have a packed basement, garage, closets and office. But the stuff has started to occupy permanent positions in the kitchen, dining room, living room, etc. No comps, classic or otherwise, in the bathrooms as of yet. I'm hoping I can develop a "one (or two) projects at a time" mentality this way, keeping a lot of excess gear down the road a bit might help me focus and see things through to completion. Yeah, I know, good luck on that too :) This has also made me rethink my plans for moving to a new house (perhaps in a year or so.) Part of my criteria was enough outdoor space that I could build a large garage or barn to hold all my gear, but even if I managed that it would be unheated/cooled, much like a storage facility, and thus only fit for certain storage. Perhaps I should just settle for a large (dry) basement. OK, this is becoming too much like a 12-step support group. Back to our regularly scheduled collecting... -- jht

Burroughs parts?

by rtellason＠verizon.net

I have some of the following parts, maybe you guys can help me ID this stuff? -- Several tubes of what appear to be resistor packs, branded "Beckman" and bearing the part number 1899-258-0, not found under Beckman anywhere --3 tubes of white ceramic-cased w/gold chips marked 1449-1112, I *think* this is some kind of DRAM? Also probably _not_ Burroughs, a tube of 18-20 parts with the number 8041016A on each of them and what I *think* is a Tandy logo (T on the top, C on the bottom, sort of an hourglass shape?). Can you guys help me figure out what these are? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.

Need a CBM 8032 keyboard

I'm looking for a CBM 8032 keyboard, or possibly just a key/keycap. I've got an 8032 with a damaged numeric keypad that I'd like to bring back into full working order. A replacement keyboard would be a good place to start, so I thought I'd ask here. I'm in the US, 84106, so shipping from the EU is probably more trouble/cost than its worth.

The tool is too smart. In some case, I've taken a small maget and dragged it along the surface of the disk to remove all of the original format. It needs to make contact with the surface so you need a method of rotating the disk inside the case. Avoid scratching or denting the surface or it will be useless. The other possible problem is that there is something on your drives head that is scratching the magnetic material off. If you've not cleaned the heads in some time, don't blame the disk. There are some disk that others have reported to have failed but I've personally never seen one to fail without cause. The most common on 3.5's is contamination of dirt from carrying around in pockets. Next is dirty heads. I've even seen oily fingers from small children. If the surface is being removed, the heads will surely need cleaning. Dwight _________________________________________________________________ Learn. Laugh. Share.

Soem have had luck with adjusting the track zero sensor but what I've seem is related to the small plastic ball bearing used in the slides. For some reason these tend to get flat spots and don't roll well. Once this happens, all kinds of problems happen.

Looking for "VT100.TDV" for an Alpha Micro

by spectre＠floodgap.com

I've spent the weekend getting my new acquisition, an Alpha Micro Eagle 300 with AMOS 2.3a and AlphaTCP on an AM-65 console, up and running. After a few false starts, I now have the Ethernet configured, TELNED set up for remote login, FTPD, and HTTPD. Eventually I'll probably put it out there as a "fan server" running on real hardware, put up some FAQs, etc. However, I can't for the life of me find any VT100 or VT100-compatible TDVs in DVR:, so I've been logging in as a dummy terminal with TELTYP. This is pretty crufty. Anyone running an AM system with a VT100-compatible TDV I could "borrow"? VERIFY TCP checks out, so I don't think I'm missing any files. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- The world will end at 3 p.m. today, to be followed by a brief symposium. ---

(If that's not sync on green I don't know what is) So its cable time this weekend and see if we can't get some colour out of the Rainbow. (Cue Judy Garland .. Somewhere etc.....)

Value of a PDP-11/23 ?

by James＠jdfogg.com

It is hard for me to admit this, but I have a PDP-11/23 that I will never get around to doing anything with. I need to find a new home for it. It's complete, was running, needs RL02 disk packs. Comes with two VT100's and an LA36 Decwriter II. It is configured exactly as in this picture (I don't think it's a plus though). http://hampage.hu/pdp-11/kepek/1123PLUS.JPG I have cash into this project. I'm wondering if there is any value to this system. Have PDP's reached "collectable" status yet? James -

DEC hardware & software available (UK)

by james＠machineroom.info

Hi, I picked up a job lot and about half of this is DEC. I'm not a DEC collector (shock!!) but I know many of you are. I'm in Southampton, UK. I'm happy to post this stuff (UK only, sorry!) if you cover costs, but would of course prefer collection. I don't have any working DEC kit so this is all untested. If you get something that works and you feel is worth money then make a donation to Cray-Cyber (www.cray-cyber.org) or your favourite charity :-) Hardware: Approx 90 * TK50 "CompacTape" cartridges. These are all in cases, many have VMS 5.5 or system backups. Some look new. There's also about 10 of "CompacTape II" cartridges. I'd like to cover my costs and ask ?50 for the whole lot (DHL delivery would be about ?13). I may split if there's no interest in the lot. TZ30 drive. Powers up but flat cable on side has been broken so this is spares/repair LK401 keyboard 3 mice. 2 * 3W3 -> BNC cables keyb/mouse interface "box" (plugs into back of 3000) VSXXX-AA B03. Nice puck style mouse missing cable - suspect spares/repair PCPI H-DC external power supply H7819-AA internal PSU.

Has CD, 2 hard disks, 16 memory sticks & PMAGB-B GFX card. 8 * memory sticks. 80 pin. 514100-10 chips on both sides PMAZ-A SCSI card PV2 "lights and switches" card Motherboard. Can't see a part number! has 8 * 80 pin memory slots (unpopulated), dated 1992. Possible part numbers are 5421177 & 50-21176-01. Has 50-20429-01 card mounted. CPU card B3004-DA 466MHz 21164 4MB cache GS-2 GFX board set? (24 plane frame buffer & another card with i860 and a DEC VLSI - 5420450 or 07292-5562) About 10 assorted cables - mix of RS232/keyboard/AUI?

You could use other connectors, like RCA phono, but BNC are standard. RJ11 socket, chassis mounting (for LK201 keyboard). Chassis mounting sockets of this type are very hard to find. I ended up making a bracket to clamp a PCB-mounting one to the panel Metal box of a suitable size to hold the above connectors (apart from the DA15S). 1m cable. At least 4 75 Ohm screened cores and 6 single wires. I used a 'unversal SCART cable' which has 6 75 ohm screened cores (I simply ignored 2 of them), a 4 way screened cable (I used this for the 4 keyboard connections) and 4 other wires (2 in parallel for each of Power 12V and Power Gnd). Possible monitor combinations : ------------------------------- 1) VR201 only This is pretty useless, but you can connect a VR201 mono monitor using the DEC lead to the DA15P on the box. Connect the LK201 keyboard to either the VR201 or the RJ11 on the box. 2) Standard composite mono monitor Connect monitor input to 'mono' BNC on the box. Connect LK201 to the RJ11 on the box. This works just like a VR201, but you can use any monitor 3) VR201 and separate mono graphics monitor Connect VR201 to DA15P. Connect LK201to either RJ11 on the box or to VR201. Connect second (composite) monitor to the 'green' BNC. You can use the dual monitor driver for GSX and have text on the VR201 and graphics on the second monitor 4) Two composite mono monitors Connect one to 'mono' BNC, other to 'green' BNC. Connect LK201 to RJ11 on box. Using the dual monitor driver, you get text on the first monitor and graphics on the second monitor 5) RGB (sync-on-green) colour monitor (e.g. VR241) Connect monitor inputs to BNCs as follows : Red - Red Green - Mono Blue - Blue. Connect LK201 to RJ11 on box. This gives the standard DEC color monitor connections giving green text and colour graphics using the colour monitor driver 6) RGB monitor and VR201 Connect VR201 to DA15P on box. Connect LK201 to RJ11 on box. Connect color monitor as follows Red - Red Green - Green Blue - Blue This gives separate text and colour graphics displays when used with the dual monitor driver 7) RGB monitor and composite mono monitor Connect mono monitor input to 'mono' BNC.

rainbow color cable

by emu＠e-bbes.com

Hi all, saw the discussion about the rainbow, and decided to give my a try. But, I don't get any color output ? The color option is installed ;-) BTW, the cable I'm using is the BC06. Manual says, that it should be BC17. Anybody knows it is the problem ? What is the difference between them ? Thanks

PERQ T2 faults

by silvercreekvalley＠yahoo.com

Jules, My PERQ T2 does exactly the same thing. The dreaded 010. Eventually if left for a while (10mins+) it goes to 013 which I think is drive time out. Once I get chance I'm going to put a Logic analyser on the disk terminals to get a better idea what's happening. I also tried a ST-506/412 drive with the same result. Tony also mentioned that its possible to connect an analyser to the front of the CPU card to see where the CPU has stepped to. Cheers Ian > This machine has a 5.25" ST-506/412 drive in it.

Various items in Essex England

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

I'm in the process of preparing to move house and some stuff is just going to have to go! If I don't get serious expressions of interest* within a week they are going. (* A "hell no, that's too rare to throw away" might lead to a stay of execution ... but unless quickly followed-up won't do much good) Items will have to be collected - they are currently part of the contents of a 20' container in a small industrial estate near the A127/A130 junction (not far from Rayleigh). It is just possible that I can be persuaded to make one trip up to Bletchley if there is interest there. For the moment I have 3 classifications: SUN stuff Apple Mac stuff Other The SUN and "other" items that don't get interest here will find their way into a skip. The Mac stuff is to be considered one lot (take it all or nothing) and if no interest here will go to eBay (and then to a skip if no interest) Haven't yet inventoried the SUNs - there are several 10s, 20s, a couple of 5s and some Ultras - at least a 1, some 30s, possibly a 60, possibly a 10 loads of MBUS and SBUS modules including lots of ROSS processors also some memory and SCSI drives. (I'll be keeping a couple more SUNs) In the "other" category are, at least, the following personal DECstation 5000/25 DEC 3000 400 Silicon Grapics O2 (this has Irix 6.5 - but I don't have a known id password ... and it uses SGs own filesystem so I can't just put the disk on a SUN and hack it that way. a few other weird and wonderful boxes and other minor items (such as the board set for connecting two Novell servers together in a SFT III setup) An unusual PC - dual P90 with PCI and EISA slots (2 adaptec SCSI boards) an A3 plotter - cannot remember whether it is HP or Roland when I get round to finding it there'll also be a HP unix workstation various home computers of the BBC & ST/Amiga eras (not yet sorted) The Mac list is quite long a SE, a IICi, Quadra 650 Powermacs - 6100/60 (x2) 8600/230, 8500/180, G3 (x2) these have all worked, but testing last week only got fully positive results from the 8600 and one of the G3s also some keyboards, monitors, books, and software I'm still delving into my garage, loft, and spare bedroom ... more may yet be found :-) email me if you are seriously interested - reply to the list if you think someone else should be :-) Andy No virus found in this outgoing message.

Shifting meanings: "Spaghetti Code"?

by cclist＠sydex.com

In an EETimes online article today, I read the following paragraph: "Among its other features, Morrison said COSA allows more dynamic changes in software than traditional methods, enables fast pre- empting of threads and brings a new level of traceability to processes. It is also easier to debug because it does not use the structures of nested if-then-else statements known as spaghetti code popular in conventional programming languages." Nested "IF-THEN-ELSE" is now spaghetti code? I'd always understood the term to mean code with lots of conditional GOTO statements (In FORTRAN, sprinkle in a bunch of computed and assigned GOTOs and you're talking real pasta). When did the meaning change? Was it when the GOTO statement was pretty much deprecated in just about every modern programming language? I can recall when "structured programming" was popularly held to mean "no GOTOs". Cheers, Chuck

Comdyna GP-6, Minivac 601 documentation

If one jumpers the SW to the OP, the 4 push switches control the intgrator action. IC stands for Initial Condition ( you can put a specific start voltage on the caps ). HD stand for hold ( useful for taking reading of several outputs at the same point in the simulation ) OP This is the normal operation with the integrators working from model stimulous. RO it the same as above except that it does a IC after some time length ( specified by the rotory switch ). The SW pin could also be controlled by some opamp or external signal. There are three voltage levels that control initial condition, hold and operate. The web page also says how to connect the multipliers to opamps. There are a number of control courses, at various universities, that show how to configure the Comdyna. The value of the resistor shown as 1 is 50K and the .1 is 5K. Knowing this, one can use external resistors to extend the setting used. Of course, the two pots in the center could be used. The coef pots are useful for offsets, stimulous and initial conditions.

A calculator is a good example. It is too bad that not all software makes sense as a state table, just as an all OOP solution can be clumsy. Some of the best software I've seen was written by a friend. It was for a Reed-Solomon error correction. When he showed the code to his manager, the manager said he sent the wrong file. What the manager thought he saw was the specification for the code. What he really saw was the actual code. When code is written that well, anyone can maintain it. I've seen bad spaghetti code done in most any language. The worst was still in BASIC.

Unibus, qbus, Shortbus?

by silent700＠gmail.com

It appears I need to take the bus to DEC101: I have a MicroVax II in the BA23 case. I'd like it to have a SCSI card. This machine takes qbus cards, I believe. I recently acquired a CMD CDU-720 card, which appears to be a nice (and nicely documented) card that supports all kinds of devices, and speaks MSCP to the Vax. But, it is Unibus. Am I out of luck here? I gather there are bus converters. Are they rare? Are they reliable? Should I save this card for the day I happen upon bigger iron? Thanks! -- jht
