lk401 keyboard protocol?

My fundamental points are: 1. Every person on Earth must be required to know the fundamental principles of Computer Science, including the principles of character coding. 2. People must realise (just like ancient pagans did) that codes are more primary and more fundamental than character shapes. To illustrate my point: most people believe that letter 'A' is fundamentally a tent with a bar between the slopes, and that 1000001 is one computer representation of it. This is what I am challenging, I argue that letter 'A' is fundamentally 1000001 and that the shape with two slopes and a bar between them is merely one possible representation of this fundamental 7-bit code, a representation that is a passing fad of a society that uses handwriting, printing, paper, and other barbaric antiques like this instead of directly transmitting binary codes from one computer or brain to another. 3. Keyboards, just like all other tools, need to be viewed in this light: it is not a device for entering a certain set of graphic characters, it is a device for entering a certain set of codes in some charset. This is what the IFCTF keyboard definition is all about. MS P.S. Oh, and the Latin alphabet needs to be renamed by law into ASCII International Reference Variant (IRV) alphabet.

TCA240 pinout and a little data

by ard＠p850ug1.demon.co.uk

Jules Richardson (IIRC) was asking about this chip to repair a classic computer peripheral (so it is on-topic)... I can't find it in a databook, but I've found a circuit that uses it -- the 'Head Amplifier Playback' module (board P50) in a Philips VR2020 VCR [1].It seems to contain 8 NPN transistors and nothing else (at least the schematic of that board shows the internals of the IC as 8 transistors only) and consists of 2 identical sections. Each is a long-tailed pair with a couple more transistors acting as a current sink for the 'tail'. Anyway, here's a pinout. There may be substrate connections, etc that I don't know about, and which might matter if you want to design something round the IC. But this should be enough to understand the circuit the chip is used in. I assume the chip Jules is looking at is a 16 pin DIL package. I'll draw the schematic of half the chip, giving the pin numbers for one section, with the corresponding pins for the other section in parentheses... 14 (11) 12 (13) o o | | | | / \ |/ \| 3 (6) o-----| |-----o 4 (5) |\> </| \ / | | +-----+-----+ | | / |/ 2 (7) o-----| |\> \ | +----------o 1 (8) | / |/ 15 (10) o-------| |\> \ | | o 16 (9) -tony

At the time, one of the places I looked was your site and I recall (I think) seeing your manual. I've since been given a PDF copy, though, so I don't need a "real" one. As to the models, as you probably know, the 277 and 299 are twin drives -- they take two disks -- the 277 being single-sided and the 299B being double-sided. I only have the full spec for the 277/299, so I'm not sure but I believe the 270/272 are single-mechanism versions (ie they take one disk, not two). -- Pete Peter Turnbull Network Manager University of York

Aargh...It never ends..

Hi Actually it won't make a particularly good Jacobs ladder. If it doesn't blow a breaker, the rods will most likely melt off. It is not like a neon sign transformer that is current limited, it is a transformer that is current rated. Let me see, 60Kv at 30ma is 1800W. How long so you think the rods will hold up to such power.

Sellam - TV star !

by brianmahoney＠look.ca

Just caught Sellam on Media Television here in Toronto. The show is produced by our independent station, CITY - TV. Is this old news? Anyway, my 14 year old son called me into the room and we both watched the fairly long (for TV) interview/tour. Besides being very interesting to me, I feel it gave my son some new-found pride in what I do as a hobby. Kind of gave it some legitamacy. If anyone wants more details, let me know. Brian M.

Heath EC-1 Analog on eBay

by dwight.elvey＠amd.com

Hi John You'll note that unlike most I've seen, this one has the original component holders. Other than some dust and rust, this looks like a good unit. The fact that all of the regulators light up is a good indication. Compared to other units, this one went for below its expected value. If the seller had taken about 20 mins to dust it off, he'd most likely got another $100 or so for it.

Though it will say "ASCII or ASCII extension", and I'm sorry that I didn't make the last bit clear in my message you are replying to. > (I suppose typewriters old enough > to not contain computers don't have keyboards?) Typewriters were a passing fad of the 19th century. Computers have been around for billions of years and will be around for billions of years to come. Every living cell has a microprocessor in its nucleus (too bad biologists are still refusing to use standard computer science terminology and therefore keep reinventing the wheels of computer science), and the pagan gods and goddesses who created us (wrote and compiled our DNA program) surely used computers. The spacecraft they used to get to this planet from theirs were also computer- controlled. Oh, and ASCII terminals are also as old as humanity: every ancient pagan temple had a terminal for the priests to communicate with the gods. And yes, they used a 7-bit code, 7 being the favourite number of Enki, the god who played the greatest role in the creation of human civilisation. The 7-bit codes didn't have the graphic renditions we use today, but then the code is primary, graphic rendition (if you use one at all) is secondary. Oh, and I often tend to decode ASCII as Anunnaki Standard Code for Information Interchange, Anunnaki being the ancient Shumerian term for "Those Who from Heaven to Earth Came" (i.e., ET visitors translated into modern English), which was also the proper name by which the pagan gods and goddesses called themselves. (Different human worshippers knew them by different names, but the only true name is the one by which the gods called *themselves*.) > For that matter, based on your comment header, your Compose key is as > evil as the alt keys you're railing against, since the "what ASCII code > is it supposed to generate?" question is just as forceful - and indeed, > since you're producing non-ASCII codes, I guess your LK201 will no > longer be a keyboard when you're done. See above, I should have said "ASCII or ASCII extension", the latter being things like Soviet KOI-8 and ISO 8859 series. But when it comes to Alt, you gotta admit that it originates in the PC (PeeCee, pee sea, etc) world. DEC's adding of it to LK401 was a consession to the PeeCee world. And I won't make any concessions to the enemy. > (I was afraid a bunch of other keycodes would change or > some such). That's unlikely because keeping everything else the same simplifies the firmware both in the LK401 and in the products designed to use it. (The former needs to work in LK201 compatibility mode, and most of the latter probably accept an LK201 unofficially.) > The keypad . key seems to be dead, though I suspect that may be broken > keyboard hardware rather than anything LK401-specific. It's dead in both LK201 and LK401 modes, right? MS

Trying to ID odd board

by vcf＠siconic.com

I've got a PC ISA board here that is interesting and I'm trying to identify it. The only markings of note on the board are Okidata 21025. There is a daughterboard fitted to some sockets on the main board and it has markings of "OKI KV96-X8D" and "PU1036-4924". The main board has an Intel i960, and two SIMM slots (populated). It's also got two OKI chips with the following markings: OKI ATC IPC Rev.2.0 MSMI0S0980-014 OKI ATC HCC Rev.2.0 MSMI0S0300-018 The backplate has 2 RJ14 jacks and a DA-15 (er, the connector is actually bigger than an A shell, like a Mac video connector). It also has an audio jack. It could be a modem. It could be a voice board. It might be both. What is it? Anyone?

der Mouse <mouse(a)rodents.montreal.qc.ca> wrote: > As may be. Do they not have keyboards? Well, OK, I would argue that the keyboard of a 19th century typewriter is still an ASCII entry device. Any time you produce letter 'A', even if you handwrite it or type it on a 19th century typewriter, you are actually producing the fundamental symbol ("symbol" defined as "signal element" in communication theory) 1000001 in a roundabout way, whether you realise this or not. Kids who handwrite letters and 19th century people who typed on typewriters certainly don't/didn't realise that they are actually generating ASCII letters, but that's what they are fundamentally (see my previous message in response to Kevin). > I do? I don't know where it originated. Well, it's certainly more than 10 years old and on-topic for this list, so if I'm wrong on this, ClassicCmpers please correct me, but I think the Alt key originates at the time when people began to stray from the sanctity of the Terminal and started entertaining the fad of "personal computer" / "workstation". That's when they moved Esc and Ctrl from where the Gods and Goddesses of ASCII placed them (immediately to the left of 1 and A, respectively), thinking that people don't need them anymore. This is the shift in mentality that I am revolting against: previously everyone was required to know the ASCII chart by heart and everybody used Ctrl and Esc to enter special codes. Anyone who typed on a keyboard knew that he (yes, HE!) was sending CODES to the computer. Then the mentality changed to the current fucking M$ Word mentality, where the luser (a chick) knows nothing about Computer Science and only know "to invoke this function in Word, I press Alt-this..." > What _I_ dislike about the LK401 (and LK201, for that matter) is that > the <X] key and the right Shift key are single keys; I want each of > those to be split into two keys. Let me guess... You want it like the VT100 keyboard (and all truly Classic ASCII keyboards of the Golden Age) where in that area you had 4 separate keys generating ASCII BS, Delete, CR, and LF, right? If so, I'm in perfect agreement! MS

"This old SGI" page - anyone have a copy?

by CordaAJ＠NSWC.NAVY.MIL

Out of curiosity, what were they complaining about? If it's just the use of the SGI logo, that's easily remedied (I'll replace it with something non-copyrighted... wasn't there a picture somewhere on the web of a Rack Onyx sitting next to a dumpster?). If, however, it concerns contents, (i.e. hardware hacks to the machine) that may be another matter... however, I don't see how they could pursue this, as long as you're not reverse-engineering a PROM. I still believe you're allowed to take things apart, fix 'em and put 'em back together again.

vax 730 console boot image file?

by brad＠heeltoe.com

In my quest to boot my vax 730 I ran into the gummer roller problem. I fixed that but my tu58 seems to be unhappy. As part of debugging it I made a little DB-9 adapter for the 10 pin header so I can run tu58sim and the tu58 emulator. The 730 appears to run the tu58 at 38400 baud and will talk to the tu58 simulator just fine. So now, naturally I'd like to try and give it some valid micro code :-) Does anyone have a file image of any sort of 730 console boot? I don't care if it's current, I just need something to test. I have a tape which claims to be current but I can't read it (yet). I'll debug the tu58 shortly but in the mean time I'd like to see if my R80 works :-) -brad

Equipment upgrade in process - anyone need this?

by rcini＠optonline.net

Hello, all: I'm considering upgrading the server equipment in my house and before I shift things around or consider selling stuff on eBay I wanted to see if anyone may be interested in the system I have. I keep this equipment in the shop, which in a ranch-style house, is below the bedrooms. The half-dozen fans are pretty noisy and my kids complain about the drone. So, I'm want to put together something a bit quiter :-) The server is a Compaq ProLiant 800R rack-mounted dual Pentium Pro server with 384mb of RAM, a 9gb boot drive and a Smart 2DH RAID controller. The RAID array is in a Compaq ProLiant U1 rack-mounted array which contains 5 9.1gb hot-swap ultra-wide 7200RPM SCSI drives. I also have some spare system components to go along with it. The stuff is heavy but shippable by UPS in two boxes (I have the original crate for the U1 enclosure). It's been in continuous service for two years now. The server came off-lease from Ernst & Young. The U1 crate was new as were the drives. It presently runs Windows NT4 Server. If anyone might be interested, please contact me off-list. Shipping would be from 11791 and figure that one box weighs 50 pounds and the other about 35. I'd be interested in swapping it for an IMSAI 8080...ha ha...just kidding. About $300 plus shipping would do it. Thanks.

lk401 keyboard protocol?

I have the LK201 spec, which appears in Appendix B of VCB02 Video Subsystem Technical Manual (EK-104AA-TM, a scan is online and listed in http://vt100.net/manx/), but nothing for LK401. But I like the LK201 better, though. LK201 is more classic, more real. LK401 is a more flimsy plastic thingy. I'm also quite pissed off by and won't tolerate the removal of the Compose and Wait LEDs, and the PeeCee-smelling Alt keys are disgusting. (What ASCII codes are they supposed to generate? A keyboard is by definition a device for transferring ASCII codes from a human to a computer.) > Specifically, both shift keys give me > the same code, and both "Alt Function" keys and the right-hand "Compose > Character" key are completely dead. Yup, the LK401 is in LK201 compatibility mode. It's there so that those who love LK201 but don't have one can use LK401 as a stopgap substitute until we can seize state power in a Revolution and order resumed production of LK201s. > While the shift keys could be > wired together, the presence of an LK_KEY_R_SHIFT define argues against > that, They are wired together on LK201.

It's probably the same LK201 spec that I have from Appendix B of VCB02 TM. (I can't look at it, though, as it's a PDF, and I don't look at PDFs. If you want me to look at something, make it ASCII.) MS P.S. I'm right in the process of writing some code for LK201. Here is the header comment describing what I'm doing: /* * This module turns the DEC LK201 keyboard into an IFCTF keyboard. All LK201 * keys are given their standard ASCII meaning, and Compose feature is supported * for entry of 8-bit characters (see below). Arrow keys generate ISO standard * control sequences. The keypad can operate in numeric or application mode * like on VT100, generating the same codes/sequences as on VT100. All function * keys generate control sequences like on VT220 with some extensions. In * general, the LK201 operates like the input half of VT220. * * ASCII input from the keyboard goes into a UNIX tty. This module can be * activated by any user on any given tty, in which case the tty line is to be * connected to the LK201, and input goes into the input queue of the same tty * via ttyinput. Workstation drivers in the kernel can also attach this module * in different ways so that the hardware which talks to the LK201 doesn't have * to presented as a tty, and the input can be routed to another tty that may * also handle workstation display output. * * Input in three charsets is supported: ASCII, ISO Latin-1 and KOI-8. The base * keyboard always inputs ASCII and supports all 128 possible 7-bit characters. * If the tty receiving the input allows 8-bit input, Compose key is enabled and * 8-bit ISO Latin-1 characters can be entered. Hex compose using the numeric * keypad is supported like on VT340 and VT420, which allows all 8-bit codes to * be entered, including C1. (While 7-bit characters can also be entered via * Compose, it is intended for entering 8-bit ISO Latin-1 characters, and is * enabled only when the receiving tty allows 8-bit input.) * * An additional feature not offered by DEC is provided to enter 8-bit input in * Russian KOI-8 instead of Latin-1. If the tty receiving the input is * configured for KOI-8, the Latin-1 Compose feature is not available (Latin-1 * characters are garbage in KOI-8 environment) and the Compose key is redefined * as the KOI-8 RUS/LAT switch. LAT mode is ASCII and in RUS mode Russian KOI-8 * characters are entered per yawerty map. Also in KOI-8 mode a Meta mode is * provided which temporarily supercedes the RUS/LAT mode, entered via * Shift-Compose. In this mode the keyboard uses the standard 7-bit ASCII map * (with Shift, Caps Lock, and Ctrl working normally), but bit 7 is set. Like * hexadecimal compose in Latin-1 mode, this feature allows all 8-bit codes to * be entered. * * The VT220-like operation of LK201 can be altered in two ways to make it more * UNIX-friendly. One modification, originating in VT320, puts ESC at E00 * (upper left corner of main keypad), moves the `~ key to B00 where DEC has put * <>, and puts '<>' over ',.'. This modification makes the keyboard more like * traditional ASCII keyboards UNIX was designed for. The other modification * makes the F11/12/13 keys generate ESC/BS/LF like in VT100 mode on VT2xx/3xx * terminals, while all other function keys generate their "canonical" VT2xx- * style control sequences. This modification allows people to start taking * advantage of new VT2xx generation features while keeping the ESC/BS/LF * function of F11/12/13 keys from VT100 mode. Finally, the character rubout * key generates the erase character set on the receiving tty. * * Autorepeat, bell and keyclick can be customised like on DEC products. A note * about keyclicks though. The LK201 is misdesigned in a way that makes very * clear why keyboards should be designed and built as IFCTF keyboards in * hardware. LK201 was designed so that the host needs to configure it and then * for the most part let it take care of itself. It implements both autorepeat * and keyclick internally so that in theory the host only needs to receive and * accept its transmissions without sending anything back on every key. * * The problem is that the keyboard doesn't know whether any given key has any * function or not in the application in use (in each combination of Ctrl and * Shift modifiers), and with the VT2xx/3xx terminals we've grown used to the * keyclick being generated only if the key is defined. The keyboard isn't * really designed for host control of the keyclick either: while there is a * command to generate a keyclick, the keyboard is clearly designed for * automatic keyclick generation. So how do the terminals do it? Magic? * Well, they do a real kludge. When the keyclicks are enabled in setup, the * LK201 is configured with keyclicks disabled. When the terminal receives a * code for a pressed key, it checks whether that key is defined and thus * should sound a keyclick. If a keyclick is needed, it sends a sequence to * the LK201 that enables the keyclicks (with the desired volume), sounds the * keyclick, and disables the keyclicks right away. Of course this is ugly and * basically defeats the LK201 design. (Actually this is so ugly that I just * couldn't believe that DEC terminals do it. I had to sniff the traffic * between VT340 and LK201 to convince myself that it really does this. It * really does unfortunately.) * * In this implementation I've decided not to bother with this and to let LK201 * click on every key. In this implementation almost all keys are always * defined and generate some code or sequence. The only exceptions are Compose * in 7-bit only mode and some main keypad keys that are not defined with Ctrl. * Since these are rare exceptions and they are the only ones, I have decided * not to bother. */

"This old SGI" page - anyone have a copy?

by CordaAJ＠NSWC.NAVY.MIL

Since this is actually my page, I should probably see what's going on... admittedly, I've kind of let it lapse for the past couple of years, (things got really busy for a while...). When I first put this together, it was the only reference out there of this type for SGI stuff (which is why I did it.) Now, there seem to be a whole host of SGI specific sites, so I never really saw the need to update it... the new sites seemed to be handling the newer systems quite adequately. The last time I logged into Geocities, it was an independent company... I just tried it a few minutes ago and I don't seem to have an account anymore... Also, it seems that Geocities is now owned by by Yahoo... Also, I haven't had anyone contact me about a problem with the hacked-up SGI logo I used, but it could be because the email link on that page seems to have gone the way of my geocities acount... vanished. In the past, I have received requests (freely granted) requests by people to mirror the site, so there should be some copies available... I need to see if I can dig up my original, or download one of the mirrors so that I can see about restoring and/or rehosting it somewhere. I'll see if I can figure out what is going on, and let everyone know... -al- -cordaaj(a)nswc.navy.mil -----Original Message----- From: ben franchuk [mailto:bfranchuk@jetnet.ab.ca] Sent: Friday, February 20, 2004 10:48 AM To: On-Topic and Off-Topic Posts Subject: Re: "This old SGI" page - anyone have a copy?

lk401 keyboard protocol?

by mouse＠Rodents.Montreal.QC.CA

Does anyone know of any doc on the protocol spoken by the LK401? I've got one, and while I can deduce some of the protocol from the NetBSD driver, there are some problems. Specifically, both shift keys give me the same code, and both "Alt Function" keys and the right-hand "Compose Character" key are completely dead. While the shift keys could be wired together, the presence of an LK_KEY_R_SHIFT define argues against that, and surely the other three keys are not supposed to be dead. I conjecture that at least some of this is because it's running in LK201 mode; on comparing it to an LK201 I note that the three dead keys have no obvious analogues on the LK201. Looking at the driver I'm using, this appears to be the keyboard's fault; I see very little translation going on between the keyboard and the events reaching userland. This leaves me looking for enough protocol docs to tell the keyboard to do these. There are defines which appear to imply that sending 0xe9 and expecting 0xba in return might put it in LK401 mode, but there's no indication of what changes (for example, how LK201-compatible it is). I can of course just try it and see, but I'd much rather have real doc if it's available. I did some looking around and found a number of archived messages talking about LK401s, but none that said anything about the protocol at this level. In case it matters, the keyboard I have is MODEL NO. LK401-AA REV. NO. A03 SERIAL NO. HJ203R6565 CAT. LIST. 108RX33S-1E FCC I.D. A09-LK401 and I'm using it with a DEC 3000/300X. I'm not sure whether this is strictly on-topic or not, but if not I think it's probably close. :) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Perq 2T1 display fault

It's also very non-rectangular in nature. Chatted with my good buddy who still makes a living repairing terminals. His guess is that the horizontal yoke isolation cap is leaking/bad. This will definitely make the horizontal squoosh. Many terminals derive the drive voltage for the vertical from the horizontal flyback - thereby causing the problem you are seeing. His recommendations: 1. look for an oversized cap (electrolytic - yup one of those beasties...) near the horizontal drive transistor (generally heatsinked) that has a rating between 35 and 60 volts and a value between 2.2 and 20 microfarads. This is the isolation cap. If it is in the 2.2 to 4.7 volt range replace it with a film cap - you will never have a problem again. You can't reform this one since they put AC (albeit mostly DC) through the cap and once it goes it's gone. 2. Replace any electrolytic near anything that looks hot. 3. Inspect, clean, lubricate, and replace, if necessary, the yoke connector socket. His experience is that when the cap goes, the current through the yoke goes up and fries the connector. The bad connection will cause early failures. If the vertical problem persists, you probably have a similar problem with a cap in the vertical drive or a power supply problem. Good luck Claude Ceccon

Sigma floppy controller ?

by uban＠ubanproductions.com

I have a Sigma floppy disk controller which I believe to be for Qbus. The assembly number is 400255 rev B and S/N is 4331. It is a dual board and has a pair of 2901 bit slices and an assortment of bipolar PROMs. From the field guide, I found this entry: SDC-RXV31 Q Sigma floppy disk controller. Emulates RXV21/RX02. (Supports Mitsubishi M2696-63) I assume this is the one. Does anyone have a manual for this controller (copy or scan)? --tnx --tom

Unknown QBUS board

by sebastian.brueckner＠epost.de

Hi! A few month ago I acquired a VAXstation 3200. It runs runs very nicely with a Emulex UC08 SCSI-Controller off a 1GB full-height SCSI-Disk. There is one QBUS card in the system that I can't identify. As far as I know the VAX has been used for measurement data aquisition in a physics laboratory. The only connector to the outside is for a 40-pin ribbon cable. I got a very long (10m I guess) cable with the box so I suppose it is using some kind of differential data transmission. Unfortunately I don't know what was connected to the other end of the cable. Probably the card is useless without that second part (maybe a A/D-Converter?). The board occupies all 4 slots and is populated mostly with small ICs of the 74xxx series and some PALs. The Label says: KINETICSYSTEMS MODEL D1571 MODEL 2922-Z1B I did not find any usable information on he net. Does anyone of you know what this board does? Thanks in advance, Sebastian

VAX console and crossover cable problem

by rdd＠rddavis.org

Trying to save space and not use a real terminal at this time, I decided to wire my VAX 4000-200's console to a serial port on my Sun Ultra-1... however, nothing seems to be working when I try connecting to it with tip (the port, set for 9600 BPS, appears to be ok, since I can get an OK response from a modem). However, there's no response at all on the Sun when I attempt connecting to the VAX using tip or cu. Kermit, even if run as root, is giving me a "Sorry, write access to UUCP lockfile directory denied." message; need to sort that out, but I think that's a separate issue. The LED indicator on the VAX counted dow to three, waiting to boot, so that seems to be ok. Here's how I wired the crossover cable (typical crossover cable wiring, should work, right?): MMJ DB25 DTR 1 ---- 6, 8 DSR, DCD TX+ 2 ---- 3 RD TX- 3 ---- 7 Sig Gnd RX- 4 ---- 7 RX+ 5 ---- 2 TD DSR 6 ---- 20 DTR ----------- MMJ pinout I'm using, 1 2 3 4 5 6 - viewed from -------+ + console +--+ Any ideas as to what I'm doing wrong? Didn't use my breakout box yet, since I need to get new batteries for it. -- Copyright (C) 2003 R. D.
