[GreenKeys] Teletype Machine Availability (fwd)

by jpl15＠panix.com

List FYI: correspond w/George directly concerning this wonderful haul of TTY gear... ---------- Forwarded message ---------- Date: Fri, 21 Feb 2003 21:40:20 -0800 From: George B. Hutchison <w7ksj(a)attbi.com> To: greenkeys(a)mailman.qth.net Subject: [GreenKeys] Teletype Machine Availability GreenKeyers - - - This evening I received a telephone call from a gentleman advising me of the availability of the following teletype equipment. It is free for the taking. It is located in the Seattle area. He does not want the people at "The Source" to be rattled by a bunch of telephone calls, so please e-mail me should you have an interest. The list includes: 1 Ea Model 37 KSR 8 Ea Model 28 KSR 1 Ea Model 35 ASR 5 Ea Model 35 KSR 6 Ea Model 14 TD 1 Ea Model 14 RO Reperf 7 Ea Model 15 KSR 1 Ea Model 15 Perforator-Transmitter (Model 19 KBD) 1 Ea Model 43 RO 1 Ea Model 43 KSR Fair quantity multi-copy paper. The equipment must be removed fairly soon, as the space it is in has been designated by the building owner for another purpose. If it is not wanted by anyone, to the landfill it goes. I have no room for it. 73, George, W7KSJ _______________________________________________ GreenKeys mailing list GreenKeys(a)mailman.qth.net http://mailman.qth.net/mailman/listinfo/greenkeys

Century Data Systems (tape drive?) exerciser

by rigdonj＠cfl.rr.com

I picked up some of a exerciser box made by Century Data Systems of Anaheim, Ca. It's marked T2000B Exerciser. I THINK it might for the old Marksman T-series DC-300 tape drives. Is anyone here familar with this box or with the T-series tape drives? FWIW CDS was an early manufacturer of hard drives (1960s) and was later bought out by Calcomp. Joe

TI-99/A

by kittstr＠access-4-free.com

Hi, First off I want to thank all who contributed on using VHS tapes as storage, I really appreciate your input. Now my problem is with my TI-99\A home computer. I have noticed that the keyboard is dying. I have been having to hit the keys harder and harder and now some don't work at all. I took it apart and the keyboard seems to be one unit (not disassemble-able). The keycaps don't seem to want to come off either. I was hoping to take the keys apart and clean the contacts but I don't want to break them, if they aren't so posed to come off. Does anyone have any experience cleaning these keyboards? If they are a "toss and replace" component, does anyone know where I could get one? Thanks for any help you can provide. Andrew Strouse ( kittstr(a)access-4-free.com )

TELEX machine, modems

by gil＠vauxelectronics.com

Hi George: Most Model 32 machines seem to be Telex units; they have a rotary dialer and four buttons at the front -- but the dialer is not for telephone numbers (as it is on model 33 TWX machines which can have either a rotary-dialer or touch-tone-dialer). Telex machines do not communicate with modem frequencies, but use a speciallized DC signalling scheme, described below. However, you can drive the unit with a standard current loop interface. I can put you in touch with someone who has done this, if you'd like. If you do not have a dialer, but instead have a blank panel on the right side (CCU), you have a "private-wire" machine, which is for a simple 20- or 60-mA current loop. The M32 and M33 are based on the same crappy design, which was targeted for low-use/low-cost applications, (as opposed to almost every other teletype model, with bullet-proof parts for 24/7 operation). But I digress. M32: 5-bit baudot (1-start/2-stop?), 50-baud, ~ $0 to $50 M33: 8-bit ascii (1-start/2-stop/even-parity), 110-baud, ~ $100 to $1200 According to my manual the telex CCU is for what they called "Circuit-Switching-Service," and the buttons are labelled: START, DIAL, LOCAL, and CONN(STOP), or possibly labelled: REQUEST, CONN, LCL, and DISCONN. As I understand it, Telex is a dialup service that uses DC signaling (no modem) and is 50-baud baudot. Telex was a service Western Union brought to the US starting in 1958, after it had been used in Europe for a long time -- the 50-baud was a European standard. I belive that Telex machines had some sort of line-interface box (not a modem like an M33 twx) in the stand. Here's part of the manual description of the four-button "Circuit-Switching" (Telex) CCU: "The dialer is a conventional telephone type...contacts open and close to send dialing pulses...in the idle condition, there is a positive current of 0.005 ampere in the telegraph loop. When the calling station operator depresses the START button, it causes the shunting of a major portion of the loop resistance, and the loop current increases to 0.060 ampere. The START button must be held while switching apparatus in the telegraph exchange is made available. When the circuit is ready, the telegraph exchange interrupts the 0.060 ampere loop current for about 0.025 second. This "proceed-to-dial" signal causes the DIAL lamp to illuminate at the calling station, and it locks the shunt to the loop resistance so that the operator may release the START button and proceed to dial the number of the called station...When dialing is complete, the exchange furnishes the connection and signifies this by reversing the telegraph loop current from positive to negative, which causes the typing unit motor to start and the CONN light to illuminate. Message transmission can now be exchanged between the connected teletypewriters. The line signals are 0.060 ampere marking and zero current spacing." gil >From: "George R.

FYI: 25th Anniversary of Ward Christensen's BBS

by grg2＠attbi.com

Er, I don't think the modem was invented in late 50's. Modems have been used to send data over phone lines (and over radio) since at least 1940. They may have been called "Terminal units", but they did the basic modem things of mod/demodulating data onto an audio carrier.

Subject: Re:large disk platters?

by mmcfadden＠cmh.edu

I think there were larger platters. On Thu, 20 Feb 2003, Murray McCullough wrote: > Hi Jules, > To my knowledge the largest hard drive platter was 24". IBM the inventor may have produced > an experimental platter of ~1 m as a demonstration project to management and maybe these platters > were 'sold' or distributed to IBM employees? In about 1976 University of Missouri Bioengineering Program acquired an "IBM surplus image system" from somebody "unknown" out west. They sent a couple of graduate students to pick up the system in a U-Haul truck which was very overloaded. When we rolled the PSU down the hall on castors it left grooves in the floor tile because of the weight. There were 3 cabinet units each 6 feet high and 5 feet wide. One was the power supply, one was the disk controller and the other was the disk. It had a "very large" disk platter that ran vertically, if I remember correctly they were about 3-4 feet in diameter. Interesting noise when they spun up, kind of like turbine engine. There were two clamshell halves that were opened to access the platter, each track had a fixed head over it. Stored on each track was the image on a single display station. By switching between tracks you could access different images. There was a vacuum pump to remove the air if you opened the clamshells to adjust the heads. Each of the display stations had an integrated keyboard and a proximity or optical pen to select menu items. We wanted to investigate distributing medical images rapidly throughout a hospital. It was a one of the kind and after a few head crashes that was the end. We then bought a Ramtek display of 256 X 256 by 8 bits instead for $50K. It sat in a real compuer room with: an Interdata 8/32 a PDP 11/50 running MUMPS with 2 RK05's a PDP 11/20 running DOS-11 with 3 RK05's and a TU10. The SEL, PDP 8 with ASR-33, IBM 026 and IBM 029 were next door. Back in the punch card days of old. Mike

HELP! MFD Checker II

by rigdonj＠cfl.rr.com

I just bought this <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=25399&item=2507112537> off of E-bay. Obviously it's some kind of disk drive tester. I opened it up and the entire front panel is hand wired but I also found a commercail circuit board in it. On the board it says "MFD Checker II" "Sony" "Made in Japan". Does anyone know anything about a MFD checker? It looks as though the circuit board was once the major part of another machine and that they took the switches, displays and indicator lights off of it and rerouted them to the front panel. However there are a few things that they didn't put on the front panel; a 80 vs 70 track select (yeah 70 track), a drive select, a 300 vs 600 RPM select and a good number of test points such as the write gate. However on the front panel you can now select 2MHz, 1 MHz, 500kHz, 250kHz, 125kHz or 67.5kHz. Anybody know what that's about? I'm guessing that it controls the bit frequency that's written to the disk and that it's used to test the disk coercivity. On the original board you could only select 1F or 2F. I should add that a 2nd baord as also been added into the case. It's a handwrapped vector board with 20 SSI ICs. I'm sure that it's used to generate and select the extra frequencies and other as yet unknown functions. Anybody care to speculate? Joe

Using non-sun mice on a sparc?

by drido＠optushome.com.au

I'm trying to get Sparcstation 1 up and running with Redhat Linux, but I don't have any sun mice. I noticed as the install CD boots it looks for a mouse-systems mouse. I have some other workstation mice around here somewhere, and I think at least some of them were marked mouse-systems. Has anyone managed adapt any other mice for use on a Sparc? I know there are some commercial sun to ps/2 adapter, but $75 is a bit much to spend on an adapter for a $5 computer. I though about using a serial mouse, but porting the PC driver to Sparc is way beyond my current skill level. I could always just buy a sun mouse, but the shipping/currency conversion charges are likely to be more than the cost of the mouse itself. Any ideas appreciated...

TELEX machine, modems

by GOOI＠oce.nl

Hi George. Most likely this is a 45.45 Baud tty, often used by HAM radio amateurs. Nowadays most amateurs have turned to PC solutions for RTTY reception. We call that teletype a "carrot crusher" over here in Holland. The 5-bit code is called Baudot, and allows for uppercase characters, numbers and some punctuation. When you say "wait a minute, how is that possible with 32 combinations?" Simple, 2 characters are reserved to shift the whole mechanism from "LETTER" to "DIGIT", so depending on the previous reception of such a special character the characters that follow are readable or garbage. Radio amateurs include something called UOS (Unshift on Space). When the "LETTER" character is not properly received, the first space char makes everything "normal" again. So, to connect a 5-bit teletype to (any) computer you need a conversion program to convert ASCII to Baudot, and at the correct transmission speed. 73 - Henk, PE1CKF Ham Radio amateur and PDP-11 addict. > -----Original Message----- > From: George R.

>> To my knowledge the largest hard drive platter was 24". > > Platters of at least 36" diameter have been made; they were used > on ILLIAC IV. hmm, that's sounds about the right size. I remember the lecturer standing behind the platter and it came up to around waist height, which is where I got the 1m estimate from. thanks to all for the thoughts!

I picked up one of these today and it had multiple problems but I finally got it to boot but so far I can't get a display on the built in screen. I'm not sure but I'm wondering if the switch settings on it are correct. Does anyone have the switch settings for one of these? Joe

IIRC the early Sony drives were very nonstandard and there were several different kinds. I am sure the 70 track goes back to the very earliest Sony floppies there are others on the list that can address this better than I. I can't remember who made the Hard drive tester that I have. I got several >from Intel when they were getting rid of the 310 stuff. It covered most of the early MFM hard drives and was built in a small blue box about 12" square. A standalone process selected from a menu of drives, plug in the drive, after a while a report was printed out. The name started with an A and was three letters. IIRC.

I base that on the fact that in the fire service we DO have the right to evict people from an area in the name of safety. For instance, if we have a gas main break, we can go house to house and forcably remove people in the effected area if we feel that their life is in danger. They don't have to consent, and we don't need a court order (although I suspect if we did it without damn good reason, we could probably be sued later). We can also keep custody of the property until we are "finished" with the scene. Here in NJ that is defined as the reasonable amount of time to handle the event and any followup investigation OR until the last EMS person leaves the scene, whichever happens first. -chris <http://www.mythtech.net>

large disk platetrs?

by grg2＠attbi.com

The original IBM RAMAC disk platters were several feet across: "The 350 Disk File consisted of a stack of fifty 24" discs that can be seen to the left of the operator in the above picture. The capacity of the entire disk file was 5 million 7-bit characters, which works out to about 4.4 MB in modern parlance. This is about the same capacity as the first personal computer hard drives that appeared in the early 1980's, but was an enormous capacity for 1956. IBM leased the 350 Disk File for a $35,000 annual fee." The Control Data 808 disk drive also used platters that were at least thet large.

Victor Computer anyone?

by beegee＠eastlink.net

We had several Victor 9000's. They ran CP/M and a proprietary MS-DOS. They had built-in codec. They actually predated the IBM PC back in 1980. They were the best available computers at the time, when the TRS-80 was prevalent on the market. My dad still may have one on his closet shelf. I threw mine away when I bought my first PC clone, a 4mhz, 4 mb ram 386SX.

large disk platters?

by julesrichardsonuk＠yahoo.co.uk

I just randomly remembered the other day that when I was at uni one of the computing lecturers one day rolled out an enormous disk platter to demonstrate how hard disk technology has changed over the years. The platter was pretty huge - around 1m in diameter. Any ideas as to what system it may have come from? Im just curious really - I've not seen much really old hardware up close, but the impression I got from the pictures I've seen is that drive technology didn't typically use platters *that* large.

DEC RC25 Drives

Owen: the RC25 are DEC's attempt at creating funny things. They are MSCP disks (connect to UDA50 or KDA50) with an SDI bus.

But, I can recommend highly Multidos for the Model IV. I don't have the link handy, but if you search for it, you can find it. It's still availble for purchase in the $30.00 range last time I checked, and it is an Alternate OS for the TRS-80 that incorporates a lot of the strong points of DosPlus, including 80 Column support while in non CP/M mode. It's a nice OS, and the DISK BASIC is faster and smaller and more feature rich than most of the other ones available for the TRS-80. I remember porting my Copy of Connection-80 over to it (we renamed our custom version, Nybbles-80), and it was MUCH faster under Multidos than under Newdos/80, TRS-DOS or DosPlus, and I was able to take advantage of several MultiBASIC features to make it nicer... Boy, those were the days. I'm on the lookout for an LNW-80 Computer that works to set up a system again.

My 4.3BSD suffix is Quasijarus, not Tahoe or Reno. But my opinion on SHAC is radically different from yours. SHAC is a darling beauty. It is a problem only for cheap OSes like NutBSD and Linsux. Since SHAC is a true CI host adapter with the true Generic VAX Port (GVP) it is perfectly supported by the SCA CI port driver present in every proper VAX OS with SCA such as Ultrix. Although DEC killed VAX Ultrix before MicroVAXen with SHAC came about, source examination shows that the Ultrix V4.20 CI port driver supports SHAC (on XMI). Some day I will lift the SCA code wholesale from Ultrix and plop it into 4.3BSD-Quasijarus. MS

HP-IB Mass Storage Emulation (Help)

by jdnews＠ultrasw.com

Tony Duell beat me to this when he wrote: "There have been many devices which implemented the IEEE-488 bus (GPIB, HPIB) using a standard parallel interface chip like the 6821 or 6522 together with buffers." My Osborne 1 (Z80, 64K, CP/M, 5 1/4 floppies, tan case, '82) labeled their parallel port "IEEE-488" (aka HP-IB) and wrote low level routines for the eight basic HP-IB commands into the bios. They used a 6821 PIA to drive the port, an interesting mixing of chip families. My computer whiz high school son and I built some software around their stuff and I used the Osborne (personal) at work (DOD R&D) for several years to talk to, among other stuff, Nicolet digital scopes. I don't remember much about the details and don't know whether I can find anything useful, or readable, on the software, but the bios routines should be available in the Osborne tech literature. I still have the Oborne, but haven't tried to run it for several years, will have to see if it still lights. My next laptop was a Toshiba T1200 (80C86, 1MB, 3.5 floppies only, MSDOS, '89) which had a bidirectional parallel port implemented in a custom gate array with eight additional control signals. I remember that we tried to do a klunge to run '488 on that but can't for the life of me remember whether we were ever successful. I'll have to dig around some more in the old stuff and see what I can find. Good luck on the project Vassilis.

DEC Monitor

by survey-admin＠justASKthem.com

Frank - I found an old post at http://www.classiccmp.org/pipermail/cctech/2002-July/000309.html You list a VR201-C PRO monitor. My neighbor (& landlord) runs a tractor repair business. He's an old farmer who doesn't like to change much, and has been using the same DEC inventory system since 1986. For 16 years, he's maintained a service contract, but now that DEC was bought by Compaq, and Compaq has merged with HP, he's facing an $800 annual bill for a service contract which has only been used to replace burnt out monitors and printers (2 of each in 16 years) The monitor includes a 15-pin connector, which I'll gues is db-15, and an RJ-11 keyboard jack. Does your monitor include these connectors? Would it work on a DEC Unix system? If so, do you still have it and how much would it be to ship it to NJ - 08825?

Gateway 2000 Handbook 486 question

by Edward.Tillman＠valero.com

If your 486 is a DX, if you have 64Mb RAM, and if you had 20Mb of disk space to spare (minimum requirements for W98, excepting W98SE), you can load W98 in its "lite" or laptop version from bootable disks. W95's another matter though -- You'd need a copy of DOS 5.0 or better up and running to load it.

I wouldn't call you naive, simply misinformed and combative... You'll come around once you go out into the real world and get the data. This is the best country in the world to live in. Not perfect. Can't say we don't make mistakes, or haven't in the past... We are only human, after all... But, I think we are doing the Human thing, and the Nation thing better than any other country out there. The fact that you like to promulgate left wing lies and self abusive statements doesn't change the facts, or reality. You'd do better to keep your fantasys (disguised as politics) off this list.

RL02 docs in PDF (re:11/44)

by GOOI＠oce.nl

As I am the "scanner" of all the docs at mainecoon, I have the original CD's (and in the mean time some 3 more...) I could investigate the conversion to PDF, but it is quicker if Jay tells me what he did. I might (if sufficient interest from CC) create some webpages that helps to get to the PDF-part that contains the info you need. Saves on downloading other parts that are less interesting. Better filesnames (no spaces, e.g.) would also make life easier. Ed will have a real fast Internet connection soon, and he has many Gb's room. We meet several times a year, and Ed already suggested to host all the data.

TI-99/A

by kittstr＠access-4-free.com

Hi, First off I want to thank all who contributed on using VHS tapes as storage, I really appreciate your input. Now my problem is with my TI-99\A home computer. I have noticed that the keyboard is dying. I have been having to hit the keys harder and harder and now some don't work at all. I took it apart and the keyboard seems to be one unit (not disassemble-able). The keycaps don't seem to want to come off either. I was hoping to take the keys apart and clean the contacts but I don't want to break them, if they aren't so posed to come off. Does anyone have any experience cleaning these keyboards? If they are a "toss and replace" component, does anyone know where I could get one? Thanks for any help you can provide. Andrew Strouse ( kittstr(a)access-4-free.com )

Recent Find: Votrax PSS & VaxClusters

by pat＠purdueriots.com

I've managed to come across a 'Votrax Personal Speech System'. I've found some information from google, but haven't found out some important things like what the pinout is on the power connector (it's a DIN-5). While I can just trace the traces back to chips on the circuit board, it's proven hard to disassemble, so I'd rather not if I don't have to. Does anyone have enough information about this thing to tell me how it wants to be powered? Oh, and another thing. I've recently picked up a few 2-4VUPS VAXstations that I'm working on trying to turn into a VMS cluster. I'm hoping to create a public-access system - I remember seeing an article about another one on SlashDot a few months ago. Because of the terms of the hobbyist license, I'll need to make it a non-commercial-use-only cluster, but I'd like to make it available to list members or other people to mess around with.

HP-IB Mass Storage Emulation (Help)

by vp＠mcs.drexel.edu

I have been working for some time on a pet project to make a mass storage emulator for HP-IB systems. Given the massive improvement in capacity that has taken place the past 10 years, most mass storage devices from the 80s look pathetic. For example, take the HP 9133H which is a massive unit that can store about 5Mb. Even the compact flash cards that are bundled with popular digital cameras can do better than that. I started my project by trying to utilize the HP-IB drivers that are part of the NetBSD Open Source Unix clone (which runs on the HP 300 series), but I have come to realize that the HP-IB cards are the creating a new legacy issue. Open Source drivers for HP-IB cards are very hard to find and thus any solution that depends on them becomes de facto legacy (once the card itself is no longer sold, finding the card becomes almost as difficult as finding HP 9133H drives). So I looked hard at the HP-IB bus itself (using the schematics from the Series 80 adaptor) and it looks like a simple parallel bus. So why use a custom card, if the PC parallel port can be adapted to drive an HP-IB bus. If the PC parallel port can be used, then I can port the NetBSD drivers to use the parallel port, rather than the HP 300 HP-IB interface. The NetBSD drivers also support SS-80 compatible mass storage devices, which means that the implementation can be verified against a real HP-IB mass storage device. If this works than the drivers will have to be modified so that they become a mass storage "server" rather than a "client" (i.e. a device that responds to mass storage requests, instead of a computer that issues such requests). Small i386 compatible single board computers are easily procurable and embedded versions of *BSD and Linux systems run on these SBCs (they even accept compact flash cards or more traditional hard disks). This means that we can make a mass storage device that can physically fit inside the cabinet of the main unit (e.g. Integral PC, or HP-87). Anybody willing to provide assistance to this effort, is welcome to contact me. However, I think that going through this list may be more beneficial so that other people can contribute in the technical discussion. **vp

HP 9000 "Nova" I-class systems

The system came with no hard drives, no media, and the 4mm tape and CD-ROM were disconnected from the SCSI chain. I was able to get the thing put back together, and I finally got a copy of HP-UX 11.0, but when I try to boot off the CD (boot 52.2.0.0), it says "Bad LIF magic."

All those people who have doubts > are just stupid. I don't want to start a to-do on this list, but I couldn't let this pass.. Colin Powell showed real evidence that some people who happen to be from the Middle East (Not sure if Hussein and his people are Arabs) are doing some bad stuff. The discussion is about bad people who happen to be Arab. Not that all Arabs are bad people. And it so happens, that a lot of terrorists in the world today are from the Middle East. Used to be, terrorists were Northern Irish... The fact that some of the worst incidents have been perpetrated by people from the Middle East does not make Americans, British or others wrong for noticing it. If anything, it means that it calls for others in the Middle East to speak up and use the social pressures or peers to put a stop to their fellow citizens (all these bad people must be SOMEONE'S brothers, sisters, sons, daughters, cousins, neighbors...) doing all this bad stuff. The displeasure that is aimed towards Middle Eastern people from people in the West is because this isn't happening. People are being killed daily, and instead of having Millions of people stand up and protest that.... We have millions of people stand up and protest somebody trying to put a stop to it. Yes, I think that's stupid. And I think the people who condemn the police instead of the criminals, are stupid... > We all know a good A-rab is a dead A-rab. Fuck > them.

That'll end all > terrorism forever and ever and we can live happily > ever after guzzling all the free oil we want. Not all American's or Westerners believe this. While I would like that Terrorists get no money at all, from any source. And I'm pretty sure lots of Saudi money does indeed go to support terrorism. Drug money from Poppy sales also goes there, and other money goes there also. I would like to see the oil money stay in the Middle East, but used to feed and care for the people there. To provide water, sanitation, schooling, and good lives for the people in Middle Eastern countries. Rather than being spent on Terrorism, Weapons of Mass Destruction or persecution of Non Muslim peoples. That is VERY frustrating for Americans. I contribute money to charities all the time, and just get sick when I think of all the Billions of Dollars spent on weapons and death that instead should have been spent on life and making the lives of people better. People who are Anti-American, and Anti-Bush just don't know the truth about Americans or George Bush. They buy all sorts of stories that aren't true. Make up motivations that aren't real. We liberated Kuwait, but if you notice did not take the country over. We returned it to the rightful rulers. We've done the same throughout history. History shows that Americans aren't interested in ruling the world, only liberating other people to be free and happy. So, let's get back to discussing Classic Computers... Regards, Al

Designing around a 6502 (was Re: Assembly on a Apple IIc+)

by dwightk.elvey＠amd.com

Hi There was some software multitasking done on 6502's, as well as other machines. This was done in Forth ( both preemptive and various round robin taskers ). Forth has the advantage that a task state can be saved with just two pointers. You do need to swap task at word boundaries. This can cause a little latency if it is a interrupt driven tasker. ( "word" here refers to the minimum executable unit of the Forth engine and not the address size ).

11/44 basic newbie help request

by jwest＠classiccmp.org

I wasn't going to dig into my 11/44 system until I finished the 2000/Access system, but due to circumstances beyond my control I had to dig into it already. I have some really simple basic questions perhaps others can point me in the right direction. First: It would appear the first 8 or so cards are required to be in certain slots. Cpu set basically. If I don't have FPP or CIS stuff, those slots get left blank? Do any grant or jumper type cards need to be there if FPP and CIS cards aren't present? Do you need to change jumpers/switches on the other cards that make up the cpu if there is no FPP or CIS? After the cpu set comes memory. I know these need to be set for what area of memory the card is for. But according to the cover on the lid, there is about 4 slots for memory. Then there is a jumper card that joins the two backplans, 9300 or 9200 I think. I have an 8 port mux card. I assume it can't go in the memory slots. So do the empty memory slots (don't have enough memory cards to fill all 4 slots) neet any kind of grant card? If I recall correctly, after the memory is the jumper card that joins the two backplanes... the 8 port mux could go next? And then next I'll put in a RL01/02 controller. Then there is a buss termination card...I assume that goes right after the RL01/02, are there any other jumper/termination/grant cards that need to be in place? Also, from what I recall of the Qbus stuff I have, the various peripheral cards need to be set for where they appear in memory, the address of the card, correct? So.. need to find docs on the 8 port mux and the RL01/02 controller. Second: Looking at the TU-58 drive, the rubber rollers in each drive appear to be highly questionable - pretty gummy. What's the best way to fix those rubber rollers? I was thinking of cleaning off the rubber, and maybe getting a vacuum cleaner belt and building a new surface by cutting it to size and wrapping it around the metal cylinder. Just how touchy is the parameter for the diameter of that wheel if I'm off, making it slightly thinner or thicker? Is there a better way? Third: I'm looking for just the top cover of the lowboy rack the 11/44 is in, and another rack of the same exact style to put my two RL02's in. Don't know what the rack is called, but it's the standard cream colored lowboy rack that the 11/44 is typically seen in that has an opening in the front door for the dual TU-58 drive. Thanks in advance for any guidance! Jay West

Slide rule article in today's Wall Street Journal

by evan947＠yahoo.com

Hi listmates, some might be interested in this: - Evan K. ========================= Calculating Collector Scours Globe Hunting for Slide Rules By PUI-WING TAM Staff Reporter of THE WALL STREET JOURNAL KELOWNA, British Columbia -- Walter Shawlee opened a wooden case and lovingly pulled out a 12-inch piece of Lucite etched with numbers and symbols. "There are only so many of these remaining," he said. To virtually anyone old enough to remember the slide rule, it's an ancient relic that was deservedly consigned to the trash bin. Not so to Mr. Shawlee, 53, who has launched an international hunt for these mathematical instruments that use logarithmic scales to multiply, divide and make more complex calculations. Mr. Shawlee taps his network of contacts from Singapore to Venezuela to check out the back rooms of musty stationery stores and bookshops. He has recruited his wife, Susan, to track down old slide-rule inventories. And he spends up to eight hours a day restoring battered slide rules, and combing the Internet, estate sales and flea markets. He says he makes $125,000 a year reselling slide rules he acquires. "When we used slide rules every day back in the 1960s, we were able to send people to the moon," says Mr. Shawlee, who came of age when the device was still the rule in trigonometry class. Slide rules, which resemble either rulers or discs, were a boon to the mathematically minded and a bane to everyone else. To multiply two times two, for example, the user moves the "zero" of one scale to the number two on another scale. Then the user looks at the number two on the first scale, and above that is the number four. Confused? So were many other people, which is why the slide-rule industry took a big hit in 1972, when Hewlett-Packard Co. launched its first scientific hand-held calculator. Almost overnight, demand for slide rules dried up, wiping out venerable manufacturers such as Pickett Inc. and Keuffel & Esser Co. and leaving boxes of unopened slide rules in stores, warehouses and schools. In the ensuing decades, a flicker of interest in the instruments was kept alive by a small community of collectors. In Emeryville, Calif., enthusiasts formed a society to show off their collections. In Dallas, some collectors still hold an annual competition to see who can make the speediest calculations. But slide rules are more than quirky bric-a-brac to the true believers. Many engineers still swear by them. Some teachers today are reintroducing the devices into classrooms, arguing that they foster more-complex thought processes than electronic calculators do. At the University of California in San Diego, Prof. Joe Pasquale launched a freshman seminar on slide rules in January. "I always felt we lost something when we stopped using slide rules," says Mr. Pasquale. "They're so much more an extension of your mind than a replacement to it." A slide rule made by A.W. Faber Castell Vertrieb GmbH, now discontinued, is one of the most popular models among collectors. The problem is slide rules are getting harder to find. Of the few manufacturers that survived the calculator tsunami, most produce only a few types of slide rules and often in limited numbers. Concise Co. in Japan still makes circular slide rules, for example, but the quantity "has become much smaller," says spokeswoman Chiho Takayama. American Slide Chart Corp. in Carol Stream, Ill., annually makes 25 million cardboard slide-charts, which are similar to slide rules, but they are "largely promotional," says Julie Johnson, the company's president. Thus, many would-be buyers turn to Mr. Shawlee. "He's Mr. Slide Rule," says Ted Hume, a 64-year-old engineer in San Angelo, Texas, who sold off part of his slide-rule collection to Mr. Shawlee several years ago. "Walter knows everybody in the slide-rule racket. He does everyone lots of favors and he'll buy slide rules from you or barter them." Mr. Shawlee's impressive slide-rule stash was on display one recent morning at his crammed office in this Canadian resort and winery town, a 40-minute flight inland from Vancouver. Several hundred slide rules, most in mint condition and in their original boxes, were stacked floor- to-ceiling in a room where Mr. Shawlee also runs a business that repairs and designs engineering equipment. At home, he has another 1,000 or so slide rules scattered across the dining table, in his home office and in his sauna. At any one time, Mr. Shawlee, a transplanted Californian who emigrated to Canada three decades ago, has 1,500 to 3,000 slide rules in stock. He says he acquires about 10% of his inventory through eBay, while the rest comes from private sales and through his extensive network of slide-rule hunters. He resells many of the slide rules for as little as $10. Some models go for $600, depending on the rarity of the rule, and he can sell a truly uncommon one for as much as $3,000. Mr. Shawlee fell into the slide-rule trade shortly after he accidentally rediscovered his old high-school slide rule in a desk drawer in 1992. "My eyeballs snapped open," he says, recalling how he carried his slide rule on his belt as a kid. "There's just something magic about them." He started a collection, setting up an informational Web site on the devices in 1997. He received dozens of inquiries from people asking where they could buy the instruments. TELL ME A STORY Read selected excerpts from the anthology "Floating Off the Page: The Best of The Wall Street Journal's 'Middle Column.' " That was when Mr. Shawlee started amassing stockpiles of slide rules from other collectors. Over a few months, he bought more than 300. "Are you trying to corner the slide-rule market?" his wife nervously asked him as the hoard continued to grow. Mr. Shawlee always puts aside about $5,000 in cash to be ready to wire for a purchase. One of his largest hauls came several years ago from a contact in Singapore, attorney Foo Cheow Ming, whom he met via an e-mail correspondence. After one e-mail discussion with Mr. Shawlee, Mr. Foo went to an old bookstore in downtown Singapore and asked the owner whether he had any slide rules. "How many crates do you want?" the owner replied. In the back room, Mr. Foo discovered 40 unopened crates, containing more than 12,000 slide rules of all types. "I found the mother lode," says Mr. Foo, who had no interest in setting up his own slide-rule dealership and shipped most of the crates off to Mr. Shawlee, who paid a bit more than $8,000 for the lot. "Since then, I've never stopped hunting for Walter. I've gone to Kuala Lumpur to look and still plan to go to Penang, Bangkok and Shanghai to find some," Mr. Foo says. "It's all in the thrill of the hunt."

Transfer of Files From RSX-11 (fwd)

I wrote this gentleman off-list (as the S/N ratio is rather out of hand just now) and asked some basic questions... mainly trying to find if he had just a disk, or the who thing. Follows is my reply to his response; if anyone can jump in with more or better info for him, please respond directly and cc: the list. The meta question is: what's he gonna do with the system once the data is mined??

Hmmm... a lot of RSX systems had Kermit as part of the Distribution Kit.. you can try: MCR> DIR kerm*.*,* but if your disk is big and you CPU slow, this can take upto an hour to complete. OR, you can use a Terminal Emulating program on your Wintel machine (I use VanDyke's CRT on my IBM Thinkpad running Win2K). Then, find the file(s) you want, and use the RSK 'type' command to list them to the port you are attached (logically and physically) to. Use your terminal program's "logging" or "screen capture" function, and... there you are! The files are safe on your PC. (This assumes you have a multi-port set of serial terminal connectors attached to the computer. This procedure can also be done using the PC terminal emulator attached to the DEC system console port. The object is to list the files as an ASCII stream and capture that listing on the PC's HD. This will work with any storage media on your DEC computer, HDs or Floppies, by the way. Please write to the classiccmp list during this process, and we will all try to help out as much as possible. I will also forward this correspondence to the List. Cheers John

TLC Ideas for LA120 Keyboard?

by jss＠subatomix.com

Well, my DEC LA120 is almost perfectly operational. Its only problem is a set of keys that do not work when pressed. I'd like to fix that. What I see when I remove the keycap is a square plastic housing that slides vertically within a larger square plastic housing. The smaller housing slides down when one presses a key. A spring below the smaller square housing pushes the housing back up when the key is no longer pressed. Up through the smaller housing shoot two electrical contacts. The contacts are fixed and do not slide with the housing. When the key is up, a plastic bar across the middle of the smaller housing holds the two contacts apart. When the key moves down, the bar moves down and no longer holds the contacts apart. The contacts touch and complete a circuit, and the LA120 senses a keystroke. Top view (key not pressed): +-A------------------+ | +-B-----+-+------+ | | | | | | | | | | | | | | | | | D |C| E | | | | | | | | | | | | | | | | | +-------+-+------+ | +--------------------+ Side view (key pressed): | | /\ | | A B / \ | | | | D E | | | | / +--+ \ | | | | / |C | \ | | | | / +--+ \ | | | +----------------+ | | /\/\/\/\F/\/\/\/\/ | +--------------------+ A = Outer (fixed) housing B = Inner (sliding) housing C = Bar that holds contacts apart when not pressed D = Electrical contact E = Electrical contact F = Spring The problem is that the circuit isn't being closed when the key is pressed. If I stick a screwdriver in there, bridge the gap between the contact, and thus close it manually, a keypress is sensed. Actually, it senses several keypresses very quickly, probably because of the noise caused by the conductive screwdriver scraping across the contacts. When I press the housing down, the contacts *appear* to touch, but no keystroke is sensed. So I figure there are either or both of two possible things going on: (1) Tiny space between the contacts (2) Nonconductive material (corrosion? oxidation?) on the contacts Two keys were fixed by using the screwdriver to bend the contacts toward each other in the hopes of creating more force pushing them towards each other. The ENTER key does not seem to be responding well to that treatment. One thing is for sure. All this stuff is so tiny and hard to get to that it is difficult to work on. Any suggestions? -- Jeffrey Sharp
