Got a box of SCSI drives a while back, and in there is one that's apparently 18G, but it's marked "LV-D" which from my understanding of things won't work with anything I have here. Can any of you guys use this?

Curiosity about power supplies (BA11)

by ISC277＠CLCILLINOIS.EDU

Okay, so I was thinking, would it be possible to replace the regulators and whatnot in a BA11 with several standard PC power supplies? Obviously there would be adjustments that need to be made, but considering the DEC units are now 20+ years old and the out-of-service modules may have dried up caps, would this not be a possible option? I'm just curious, I'm no electrician, nor have I looked over the leads yet. Secondly, if I have less than half the BA11 box full of cards, do I need both of the fans plugged in? Julian

how to connect a Kennedy 9100 ?

by aek＠bitsavers.org

> I downloaded the TC11 and TC-131 manuals. > TC11 has two 40-pin connectors As I said, different manufacturers sold slightly different cabling. The hex board is the basic controller for 800 bpi, you daisy chain the read/write cable to the quad board if you needed 800/1600 support.

how to connect a Kennedy 9100 ?

by henk.gooijen＠oce.com

I downloaded the TC11 and TC-131 manuals. TC11 has two 40-pin connectors, so you can not hook a Kennedy 9100 to the TC11. The TC-131 looks promising ... Question: who actually has a Kennedy 9100 connected to a UNIBUS machine, and (of course) which interface do you use ?

Mercury use (WAS RE: hospital surplus)

Not much use I can think of in computing, but in other things quite useful. Most obvious is gold prospecting, also used in other metalwork (tempering bath), and in a hobby that will not be named to remove lead that is stuck to steel. Also vacuum pumps for home particle accelerators.

ComputerVision Model 32 system

by compoobah＠valleyimplants.com

Gave it the dust-off and vis inspection - Base is a Sun 3/160 system, Sun backplane, 3004 processor and memory cards. it has a non-VLSI CV SCSI/2xTTY card. The VME terminator cards are CV-proprietary, and are switchable between "VME" and "CV" mode, not sure what the difference is yet. The case is CV-specific, all drives are front-mounted along with the power supply. Old-IBM type superstrong reinforced-plastic skins. The "heart" of the CADDS system is the CV-GPU, two cards connected by 3 ribbon cables. One is a Multibus "interface card", the other is the VME processing part, with 7x AMD 2901 bitslice processors. According to docs, the "GPU" system can be anywhere in the network displaying on a remote terminal if desired, which differs from SGI-type systems. Not sure exactly what is done in the GPU yet. The framebuffer is a seperate VME card, with a unusual DB-25 connector to the monitor that I haven't traced yet. There is also a bridged Multibus tablet interface card. I have docs, but they don't go very deep into hardware. Unfortunately, it looks like it uses a dongle for protection, which I don't have. Good news is that it shouldn't be too hard to workaround, given that it is a ca 1988 machine. It came with full ComputerVision "4.2 UNIX release 4" tapes, SunOS 3.2 and 3.4 upgrade, SunWrite/SunPaint, CADDS, and some other stuff. Gave me a smoke signal on the p/s test, from a cap on the VME terminator board. Everything else looks O.K., except for a broken termpwr wire in the SCSI card.

NetBSD and QIC02

by cclist＠sydex.com

Many thanks to whomever suggested NetBSD for my QIC02 support problem. I've been a long time user of Linux--my last contact with BSD was back in the 80's on a VAX--I think it was 4.2BSD. The last few years, the rot in Linux has been getting to me. It seems that every time I want to do something a little off the beaten path, it's a matter of Googling for "who else has this problem?" and finding patches and putting up with careless distros. And endless bloat implementing things that I didn't even dream that anyone could want. NetBSD (I installed 2.1 to be safe) is the way I remember Unix--no-nonsense and no-frills. The kernel compiled with what I wanted on the first try. I haven't installed KDE yet, but it looks to be pretty straightforward. The surprise is how well NetBSD functions on a lowly Pentium 166. Compiling the kernel is a matter of saying "make" just before you go to bed. Cheers, Chuck

who built the first 8086/88 based puter?

by r_a_feldman＠hotmail.com

OK. The models from the LX100 and up do have a cutom Intel "Hornet" chip, but it is an 80186 at its heart. There is a block diagram of the Hornet at http://www.daniel-hertrich.de/200lx/block.pdf.

pertec cables?

by aek＠bitsavers.org

The cables are straight through 50 pin ribbons. IDC edge connector on one end (same as 8" floppy connectors) and .1" socket on the other. I've seen normal flat used on short runs and "twist and flat" 25 pair used on longer runs. 6' or so should be fine with the standard flat grey stuff. The coupler manuals limit the length to 25'

Where have all the Selectrics gone?

by Watzman＠neo.rr.com

134.5 baud was the exact baud rate required to match the motor speed of the main shaft in the selectric mechanism. At that speed, the printer main shaft clutch would remain continuously engaged. At any other speed, the mechanical wear would destroy the mechanism VERY quickly. Obviously, with buffering and handshaking one could use a faster rate externally, but that speed was essential at the mechanism level. All selectric mechanisms, at the mechanism level, use tilt/rotate code. You tilt the ball to select a row, and then rotate it to select a column, then whack the paper through a ribbon (it's a mechanism that Tony Soprano would love). That is simply how a selectric works, and any other code will ultimately get converted into tilt/rotate before being applied to solenoids in the mechanism.

how to connect a Kennedy 9100 ?

by aek＠bitsavers.org

> What interface should I be looking for to hook it to the UNIBUS ? Some variation of an unformatted tape drive interface. They are slight variations between vendors, so you need the right edge connector to idc interface card at the drive. There should be some indication of who made the interface card on the PC board. The three connectors are read, write, and control. Unibus controllers often are either a system unit or a single quad board with a second board for 1600 BPI PE support. The Emulex TC11 and Western Peripherals TC-131 manuals are up on bitsavers Plessey and Dilog made similar controllers.

Mercury use

by Billy.Pettit＠wdc.com

Nobody's mentioned thyratrons (gas-filled triodes/tetrodes) either. I suspect the thyratrons used in ring counters, etc, were always inert gas (and not mercury vapour) ones, does anyone know for sure? -tony I know we used mercury vapor thyratrons in the Army (Signal Corps) on some of the triggering circuits on early radars. One of the NCOs made a beautiful chrome chassis and mounted 8 of them on it. Then used them to drive the spark plugs on an old straight 8 Buick. Was gorgeous to watch running at night. I still regret not getting some photographs of it. (This was in 1960 at Fort Monmouth, New Jersey.) Billy

So I hearby announce >my desire to network with other owners of the same. >And does anyone know if an 8088 add-on was ever >offered?? It seems like the most natural thing to me. > Hi Chris I have one of these. I've been exploring my machine. As far as I know, they never did a 8088 version. The 68K is really a nice machine though. Jeff Rasken's site has pdf's on the user manual's. There are also several pages describing how to get to the Forth underneath. There are all kinds of things you can do with the Forth, including writing your own special functions. You can even evaluate Forth expressions in your text. A handy place to put your source. One of the sites describes using " see " to decompile Forth words. So far, I've not found such a word in my machine. If you find it in yours, I'd really like to know. You could do a " see see " for me. The Forth is a tokenized Forth. The most common words are 1 byte tokens. There are a number of words called trier1, trier2 ... that are used to extend to 16 bit tokens. There is a way to find the token of any particular forth word. As an example, " ' find . " will display the token for the word find. If you do " ' find +table @ . " you'll get the pfa/cfa of the word find. I'm almost ready to write my own word see but I'm stuck at one point. I've found the dictionary and there is a 16 bit value attached to each entry. I suspect that this somehow is used to locate the token. I've not yet found out how this works. I've started a little by hand decompiling the word find. The word find must know how to use this value to get to the token. Words like ' use the word find inside. It is slow but not to bad. I used the word words in my text to dump the dictionary names and then wrote a keyboard macro to take each word and do a " ' SomeWord . ". It also cleans up the extra ' and . I use the word dump to look at the cfa/pfa and get the token there. I then search for that token in my text. I can only work on this during the weekend so I'd just started before I needed to go to sleep. My main reason for doing this is that I'd like to write a different printer driver to use my HP 3si. I don't have any Canon printers that it normally uses. I'd also like to here from other Canon Cat owners. Dwight

MicroCornucopia Magazine / Big Board

by gkaufman＠the-planet.org

I'm very willing to do the scanning and create indexed PDF files of the available MicroCornucopia editions. I already have 1-4, but would love to borrow 5-26 & 37-53. If Roy can locate the missing 27-36 it would be great. I'd be glad to pay round trip postage costs, and return a full set on CDR of the files to anyone willing to help out by loaning issues. I'd also eventually like to collect up the user group disks that were distributed. I found #13 on the web (which ironically starts out with 4 files I submitted back in the 1980's when I was living in Philadelphia!). I also have the PFM3.3 source code here and believe I have a bootable CPM disk that I can add to a CDR. Dave Dunfield's site also has .IMG files of disks for the Big Board I. I have the original documentation and schematics I can include. And I have a neat "CRTMON" that was a debugging monitor that doesn't use any dram to boot. It used the CRT static memory for the monitor, letting you debug problems with the DRAM section. Many thanks to anyone who can help.

Tektronix 4632 Video Hard Copy Unit -- Manual?

by legalize＠xmission.com

Does anyone have a manual for this? Its a video hardcopy unit.

pertec cables?

by brad＠heeltoe.com

Anyone have a set of pertec cables laying around they don't want? (or will sell/trade) I've decided to fire up my TS05 which has pcb edge connectors and I need two cables from the PCB edge connectors to the controller headers. I'm pretty sure these are standard pertec cables (comments welcome). I've got an TMSCP and TM11 controller, but no cables :-( -brad

First drive letters?

by Billy.Pettit＠wdc.com

As long as we're on the business of firsts, what was the first operating system to refer to mass storage devices by single letters, starting with "A"? Does CP/M have this distinction? ISIS, IIRC used F0: and F1: for the floppies. Think of all of the keystrokes saved! Cheers, Chuck The first one I encountered was the MSOS (Mass Storage Operating System) software on early Control Data 3200 systems. MSOS and MASTER were both in the field in the late 60's. I was trained on MSOS in 1966. A lot of ideas in CP/M and similar progenitors came from systems already in the field for years at the time of the early micros. Billy

Mac SE, SE/30, etc.

by marvin＠rain.org

A friend of mine passed away last month and he had a lot of Mac stuff in his garage. His widow asked me to take a look at it, and I didn't see anything worth much money. There are probably about two dozen machines; SE, SE/30, Classic?, Plus?, SI, LC, etc. and maybe a 512K along with a number of monitors. She doesn't want to throw them away, but does want them gone. If anyone is interested in these machines, let me know and I'll pass along the information. There were also some Imagewriters, and other stuff that I haven't had the time to check out yet. BTW, he did have a MAC 128K that I have now, but it was stuck in a non-128K case.

Big Board - MicroCornucopia

by gkaufman＠the-planet.org

I'm in the process of restoring a Digital Research / Ferguson "Big Board". I built a bunch of them back in the 80's, and it will be nice to have one up and running again. I was wondering if anyone had copies of the support magazine - Micro Cornucopia, or any of the Big Board User Group disks? I have the first four issues of MicroCornucopia here and will scan them to PDF's when I get a chance. I'd like to eventually scan the full set if possible. Many thanks! - Gary

DECnet for IRIX

by aijones2＠bsu.edu

So, I've been looking, fruitlessly, for a copy of SGI 4DDN or 4DLT for IRIX 5.3 or 6.2. 4DDN was SGI's DECnet Phase IV; 4DLT was their LAT implementation that required 4DDN. Resellers don't seem to feel it's a good idea to sell unsupported SGI software from fifteen years ago. Does anyone have a copy at hand? I did get ahold of a copy of 4DDN 3.0, but it turned out to be IRIX 4.x-only, and I lack any hardware that's IRIX 4-capable. (Nevermind that IRIX 4 is kind of scary) I know this is a bit of a weird request. For reasons I cannot explain, I've felt compelled to get my SGI onto the hobbyist DECnet ever since a filename with a typo in it led me to believe that I had 4DDN on-hand.

Mercury use (WAS RE: hospital surplus)

by lee＠geekdot.com

> I don't believe that anyone's mentioned mercury arc rectifiers yet as > one application of mercury (and of course fascinating to watch!). There was a 12 phase 800KVA MAR at Droitwich but that was just a big, black, steel tank with porcelain insulated terminals. The last 'visible' MARs I saw were at Daventry, 6 phase 500KVA with three rectifiers per phase. Daventry has closed and most of the original building at Droitwich has been demolished. I know of one site where the remaining mercury, some 10s of gallons all in glass demijohns, was 'lost' during building work. Of course the metal you can detect in the new building base is all steel reinforcement bars, honest. Lee.

Thunderscan

It powers up OK, but after a while goes blank, a tap to >the side restores the screen. One of the connectors for the cable which joins the logic board to the analog board has a bad solder joint on Pin 1. It's the connector on the analog board. This is an extremely common problem on the old 512 and similar Macs. There's an extra screw in the battery compartment for five total. Once you have the case open, just remove the cardboard cover from the analog board, identify the pin in question and rehabilitate the solder joint. Unfortunately, I don't know anything about the Thunderscan. I saw them back when, but never had one. Jeff Walther

who built the first 8086/88 based puter?

by r_a_feldman＠hotmail.com

The HP LX series (95/100/200/700) palmtops were probably the most successful 80186-based computers. Several million of them were sold. Relevant to the discussion of medical equipment, there was just a discussion on the HPLX mailing list suggesting that the HP LX200 (MS-DOS 5.0) is still being sold as part of some piece of medical equipment, although no one there could say for certain. It was discontinued as a separate product in 1998.

Personal Computer World magazine - Vol. 1, No. 1

Hi, I came across this link <http://classiccmp.org/pipermail/cctalk/2001-August/177990.html> via Google and wondered if you could help me with an article in Personal Computer World magazine Vol. 1, No. 1 ... I think it was the editorial at the beginning of the magazine. The editor was warning of the beginning of a new kind of "great divide" between those who have and know how to use the new technology and those who don't. I would really appreciate a scan of that article if you wouldn't mind doing that for me. Many thanks, Steve

Hi No, it is that they don't bounce and that they don't need a minimum current to clean the contacts. They are not any faster than others. Some are designed for high current operation. These look like tubes with a coil around them. No bounce means less arcing. Dwight

Computer Collector Newsletter is changing...

by evan＠snarc.net

Hello cctalkers, Some changes are in the air for the Computer Collector Newsletter. First, there is a new name. CCN is now (drum roll please) ............... Technology Rewind. Within the next day or two, our domain of http://news.computercollector.com will forward to http://www.technologyrewind.com and that will be our primary address. Also, for simplicity's sake, all of my posts to cctalk will just come from my personal email account (evan at snarc.net). Second, there will be some changes to the format. The changes are not final, but we're toying with a couple of ideas, such as dropping the subscription method and becoming a news web site rather than a newsletter per se, or perhaps following the route of a news-oriented blog. Of course, it will continue to be cost-free, with a news focus. (Anyone have ideas for additional resources we can provide? The only restriction is that we won't step on the toes of established resources such as cctalk, the VCM, etc. -- we're not going to compete against our friends.) We've given this a lot of thought already, so we hope the changes are well received, but we do look forward to all comments and questions. - Evan

Find in Seattle

by compoobah＠valleyimplants.com

Today I met up with a gentleman from Kirkland, WA (Ian Greenhoe, who knows at least one of the moderators on this list) who needed to pare down his collection due to domestic pressure. HE STILL HAS some stuff, complete HP/Apollo 9000/700 systems with monitors/keyboards if anyone is interested - give me an e-mail and I can pass it on Anyway, I got a bunch of Sun stuff, including a Sun 3/60 with mono monitor, keyboard, etc. just needs a monitor cable - contact me if you're interested I can't keep it. One of the machines happened to be a ComputerVision CADDstation (Sun 3/160 [looks like], with several customish looking cards and fancy graphics). I think this came up recently, so when I know a bit more I can post it. The BIG good news is a box of disttapes (~60, haven't been through them yet but it includes ComputerVision stuff, SunOS 3.2 & some Sun unbundled stuff) and 2 boxes of docs. I'm trying to figure out best way to get them scanned, need to inventory them, etc. I only have 2 boxes now, but will have the third. Anyway, I need homes for (1) almost complete Sun 3/60 with monitor and keyboard, nice condition but one of the VME ejectors is broken. and (1) Siilicon Graphics Indy R5000SC/150 XL-8 If anyone wants the HP 9000/700s I can forward an E-mail things that might be of interest, but might not: 1 PeeCee AT- class full tower case all in the Seatle area

This may or may not help, but I have used a 1542c with imagedisk to create mixed density floppies. Others have then used these to successfully create new images. I have at least 3 controllers that will work at SD with imagedisk. I have tried ID in single density with about 15 different floppy controllers, and have one more to test. Is there a FAQ about what controllers will write SD images? If not, I'd gladly maintain a list. Kelly

QIC02

by cclist＠sydex.com

My memory is failing again. It's been maybe 15 years since I last fooled with QIC02-interfaced drives and I'm trying to avoid doing homework that I've probably done years ago. I've got two QIC02 drive setups. One's a Tandberg TDC3650 drive connected to a Alliance Technology ISA half-card. The other's a Cipher CP125BA connected to a Wangtek 5150. I'm guessing that the Wangtek card supports hardware compression (it's got an 8085 on it), while the Alliance looks to be pretty minimalist. So here's what I'm wondering. Without preferring any particular data format (e.g. tar), what x86 platform has the best support for these things? Linux? Xenix? MS-DOS? OS/2? Windows? I've got the distinct feeling that I've been here before, but I can't recall what I discovered. Can anyone help me slice through the mental fog? Thanks, Chuck

A bunch have opening bids of $5, which is the lowest opening I've seen on dovebid (most stuff opens at $50).

POWERstation 370

by compoobah＠valleyimplants.com

The 7030/3CT (why do you suppose they recycled 7030? shouldn't it have been retired after Stretch?) is even ummm pokey with AIX 5.1 My 012/370 plods along fairly well with 4.3.3, though. I went into AIX with a bit of trepidation, having heard the BSDers whisper that it really stood for Aix Isn't uniX, and that it was mostly "UNIX compatible". 4.3 (and perhaps the rest of the 4.x series) is pretty close, except for some weirdness in the /etc files (for which smit is a godsend when you first start out). After banging my head against it a while, I have grown to admire it. I should get a faster machine, however. (interesting how RS6Ks and Alphas seem to hold their value much better than SGI/Sun/HPPAs)

Hospital surplus? (was: OT: Microsoft in the medical field was Re: OT: video signal question)

by Billy.Pettit＠wdc.com

Richard asks: So what do hospitals do with all that gear that they've had in pristine lab conditions for years when they upgrade and no longer need it? I've never seen any sort of surplus venue for this sort of thing. -- I can't speak for all of them, but I do have a cousin who has made a decent living for 30 years by refurbing this equipment and reselling to smaller hospitals or even off shore. He has built up a network of customers in the Pacific Northwest that contacts him any time something becomes surplus. His specialty is X-Ray and MRI, but any kind of medical electronics is fair game. The cost of medical equipment is such that even 20 year old electronics is state of the art to smaller, isolated hospitals. Billy

Writing Apple ][ disk images...

by paulrsm＠buckeye-express.com

For all Apple II questions, start with the FAQ: http://home.swbell.net/rubywand/A2FAQs1START.html > What are the various options available for > getting disk images onto media that an Apple ][ > can read? What disk images are you starting with? .SHK, .SDK, .DSK, .PO, .DO, .IMG, .HDV, .NIB, .2MG, or other disk image file? What hardware are you starting with? Apple II, II+, IIe, IIc, IIgs? PC? Macintosh? For 5.25" disks, the simplest and cheapest setup is a real Apple II to write the disk. You can get the data there via the game controller port, a serial port, or over a network. Hardware to write Apple II disks using a PC exists but is rare. The Mac hardware is an Apple IIe card. For 3.5" disks, the rules are different. Another way is a compact flash drive. You can remove the CF card and plug it into a PC to transfer files. -- Paul R. Santa-Maria Monroe, Michigan USA

PBXAG-AV (acceleragraphics)

by waisun.chia＠gmail.com

I have this LOOONG PCI graphics card circa 1996 (phew...just made it to be on-topic :-)) with DEC part number PCXAG-AV. It has a acceleragraphics sticker on its main GPU. Google says this was an option for the DEC Personal Workstations series... this means only on Windows NT (the 64bit version)!! *sigh* However, being an optimistic person, I'm gonna ask: Are there any other OSes out that can use this card (the ex-DECcie who gave me this told me that this was an incredibly expensive card when bought new)? Can it use in a Intel box or do I have to stick to an Alpha box? A search for manual turns up zilch.. I'd be happy to run in on any other OS than WNT; i.e. VMS, Tru64, DU, OSF, *BSD, even Linux.

Where have all the Selectrics gone?

by dm561＠torfree.net

Just happen to have a copy of "The Selectric Interface" in front of me; $5 &S in case anyone wants it. Note that it's _not_ about converting a normal Selectric to an I/O device, but about interfacing a 2740, 2980 & Dura models, which are already I/O devices (albeit with 24, 48, or 115V actuators) to an ASCII parallel port. Kilobaud had a pair of articles (Dec/79 & Jan/80), but that too was about converting an I/O unit (specifically, from a BCD (6 bit) code machine to Correspondence code). There were some other codes in use as well in other models; I had a couple and never could find a correct ball for them. And yes, there were certainly many Rube Goldberg approaches to interfacing a Selectric; I even recall seeing one of the solenoids-over-the-keyboard ones in action way back when... That was probably my post you referred to earlier about the Redactron mag card system; unfortunately the typewriter is long gone, and the mag card drives are spoken for. Redactron used a Selectric mechanism with a TTL level interface already built in, useful in case someone ever runs across one. While we're on the topic, a while back I sent a Selectric service manual to someone who sometimes lurks on this list and he'd promised to make it available on the Web (hint, hint... ;-) mike -----------Original message: Message: 30 Date: Tue, 21 Mar 2006 16:14:50 -0800 From: "Chuck Guzis" <cclist at sydex.com> Subject: RE: Where have all the Selectrics gone?

You need the quality print that a daisy wheel printer provides but the thought of buying one makes your wallet wilt. The Selectric(tm) Interface, a step-by-step guide to interfacing an IBM Selectric I/O writer to your microcomputer.will give you that quality for a fraction of the price. George Young, co-author of Microcomputing magazine's "Kilobaud Klassroom" series, offers a low-cost alternative to buying a daisy-wheel printer. <snip> ISBN 0-88006-051-4 $12.97 from Wayne Green, Inc. ------------------------------------------- So we know that I/O Selectrics were still plentiful enough in 1983 to warrant publishing a book on interfacing them.

Where have all the Selectrics gone?

by rickb＠bensene.com

Wang Laboratories had their own modifications that they did to standard Selectric Type I electric typewriters that allowed them to be automated. The automation was very complete, including the ability to set/clear tabs, and turn the unit on and off. The modifications involved making the cabinet "deeper", allowing room in the bottom of the machine for the solenoids and switches that provided the ability to actuate and report status. A "spacer" wraparound filled the gap between the upper cabinet and the base. The Model 601/701 was a standalone "deep" Selectric that would interface to Wang 600 or 700-series calculators. These were output-only devices. The Model 602/702 had further modifications which involved modifying the space mechanism so that spaces were "microspaces", and a stepper motor was connected to the platen to allow forward and reverse indexing in small steps, along with the same modifications made to the 601/701, which allowed the device to be used as a plotter, that could also do full formatted annotation and text output. Again, these were output-only devices. There was also the Model 611/711 I/O writer. This was a further modified Selectric Type I that had all of the modifications of the 601/701 Output Writers, but also allowed keypresses on the keyboard to be encoded into signals which could be communicated to the connected calculator, allowing fully interactive I/O for the calculator. Lastly, there was a "portable" version of the 601/701 and 602/702 Output Writers that provided a padded, shipping-proof carrying case that allowed the devices to be shipped around easily and safely. Some information on these can be found at the following links: http://pail.bensene.com/a-wang701.html http://pail.bensene.com/a-wang711.html http://pail.bensene.com/m-wang711.html http://pail.bensene.com/a-wang702.html I have an operational Wang 701 Output Writer, and a Wang 711 I/O Writer. Keeping these machines operational is a bit of a challenge, as they are quite temperamental keeping the linkages all in adjustment. My guess is that Wang service technicians spent a lot of time adjusting these instruments. They operate at a quoted maximum rate of 15 characters per second, but more practically, it's somewhere around 13 CPS driven by a Wang 720C calculator. I found a local guy who knows Selectrics inside and out, and had him do a complete service on the Selectric that makes up the 701 Output Writer, and he said that in "those days", he serviced a lot of the Wang-modified devices. He also said that Anderson-Jacobsen also had a similar (perhaps OEM'd from Wang) modified Selectric that could be used as a computer console or terminal.

grease advice needed

by fernande＠internet1.net

Hey Guys, This afternoon I'm cleaning up a Sony GDM-1602 monitor. I have the case disassembled, and have washed all but the largest pieces. The base is a very nice rotating and tilting design. The rotation taken place because the plastic tilting assembly rides on a flat sheet metal base. The contact area is a circular plastic ridge that was lubed with an clear-ish amber grease. What kind of grease should I use to re-lube this? I want to provide adequate lubrication between the plastic and steel, but I don't want something that will hurt the plastic. I was thinking about using dielectric grease, since it shouldn't harm plastic, won't melt out, and isn't too messy. However, it's designed as a moisture barrier, not really as a lubricant, I believe. Thoughts anyone? Thanks, Chad Fernandez Michigan, USA

OT: video signal question

I have a couple of Mitsubishi P60W Video printers (anybody want one?) and they have a remote jack (as well as a print button of course), so that'd be one way of printing from the Endoscope itself.

Where have all the Selectrics gone?

by swtpc6800＠comcast.net

My Trendata 1000 Selectric terminal went in a garage sale years ago. Here is a picture of me at the terminal. http://www.swtpc.com/mholley/MySystem/MySystemPhoto.htm A local computer store near Seattle sold these for about $900 in 1978. Several people in the Northwest Computer Society got them. We had low cost access to time-sharing on a PDP-11/70 at night that supported the terminal. I still have the documents and software if you want to hook one up to a SWTPC 6800 computer.

Where have all the Selectrics gone?

by kapteynr＠cboe.com

Kilobaud is probably a good guess. I do remember that the kit I saw had a table in PROM that looked up a "tilt" and "rotation" for the Selectric Ball.

I think that it may have been Kilobaud. There was an outfit in Walnut Creek that sold a conversion kit that mounted under the Selectric. Fairly complex, and required tinkering to keep it running. There were also a number of units that consisted of boxes full of solenoids that sat on top of the keyboard, such as KGS80 and Rochester Dynatyper. At the West Coast Computer Faire, around about the 5th or 6th one, there was an outfit demo'ing a unit with lots of pulleys and fishing line, that was printing on a MANUAL typewriter.

archival cd-r - really true?

by Watzman＠neo.rr.com

On recordable CDs, the data is on the label side and scratches can remove the data. On DVDs, the data is inside the media, between two layers of plastic. Scratches cannot permanently destroy the data proper as they can with CDs. The risk is that DVDs can delaminate, which will destroy them. Also, air getting in between the two plastic layers laminated together (with the data between them) can destroy the data by oxidizing the dye layer. This form of failure occurs from the outside in. A logical suggestion that is often made is to not use the last 10% to 20% of the media to increase it's resistance to this form of deterioration. Also, it is critical to avoid any storage or handling that flexes the media even slightly. I don't buy the "spiral track" argument that was made against optical media. These are "random access" media, not sequential access. If you don't believe it, put a full data CD or DVD into your drive and read any file from the CD. You can hear the "seeking", and the time required to get to a file is clearly nothing like the time that would be required to read from the start of the disc to the selected file. The condition of the middle of the disc has no bearing on the readability of data at the end of the disc unless, on a particular disc, a directory or some other critical data structure just happens to fall in a defective area. I think that most of the problems that we see are really with bad burners, and this can mean marginally bad burners (no indication of a problem, but the laser is weak and the media is not heated to the proper temperature, and may subsequently "fade" as a consequence). My own experience (I repair computers and see more drives than most people) have convinced me to stay with Samsung for CDs and Pioneer for DVDs (although Pioneer had one bad model, the "09's"). Other than that, I'm convinced that well burned optical media is the best storage media we have ever had, but I think that the media is the very least of the issues. Burning, storage and handling, I think, are every bit as important as the media itself. Two very important rules: NEVER use "RW" media of any kind, and never use "packet writing" to burn your media (e.g. stick with ISO-compatible formats).

old literature

by rtellason＠blazenet.net

Is there any interest in old literature? I went into a file cabinet last night looking for something else and ran across a bit. If it is of interest, I'll do some digging and see what all else I have that may be of interest, but here's one example: In a folder labeled "Digital Equipment Corporation" :-) A brochure labeled "PDP-11 Microcomputer Members of the PDP-11 Family" A smallish brochure "Introducing Fierce Competition for 8-Bit SBC's" with the inside saying"Digital's new 16-bit FALCON" and an actual-size picture of the card. A spec sheet "Falcon SBC=11/21 Single Board Computer" MRV11 Option Bulletin: "EPROM/PROM/ROM Module" PB11 Option Bulletin: "Universal PROM Programmer" Brochure: "Microcomputer Products Selection Guide" including a very nice table "Backplane Selector" Brochure: "Announcing a new dimension in microcomputers: LSI-11/2" Anybody want this stuff?
