One frequently cited source is Sharon Industries of | San Jose, California. As of [1998-02-23], I have verified that Sharon is | still in business and can still repair several models of Televideo (TVI) | terminals. However, Sharon may not have every manual for every model of | terminal, so you should call by voice and ask what is available. | +1 408-436-0455 However, as of 2007-09-26, there is a corporate entity called "Televideo" which can be reached by calling +1 408-954-8333. ////////////////////////////////////////////////////////////////////////////// Path: utkcs2!gatech!asuvax!cs.utexas.edu!qt.cs.utexas.edu !zaphod.mps.ohio-state.edu!cis.ohio-state.edu !hydroplane.cis.ohio-state.edu!dmiller From: dmiller@cis.ohio-state.edu (david s miller) Newsgroups: comp.terminals Subject: Info about Televideo Message-ID: <1991Nov14.205301.16116@cis.ohio-state.edu> Date: 14 Nov 1991 20:53:01 GMT Sender: news@cis.ohio-state.edu (NETnews) Organization: The Ohio State University, Department of Computer and Information Science Lines: 86 Originator: dmiller@hydroplane.cis.ohio-state.edu I recently saw many postings concerning Televideo terminal switch settings so I thought I would post this for the general public. Televideo is still in business [as of 1991] somewhere just outside of San Fransico, California. They do have an 800 number which can be obtained through directory assistance. When I called them concerning a question for a Televideo 910 terminal, they said that they no longer service that line, but they could provide me with the switch settings if I needed them. They also gave me a number of the company which bought the rights to maintain the Televideo 9xx line, and I was told that I could order parts and manuals from that company. I don't have that number now or I would post it. The following is excerpted from a letter I received some time ago. I hope it is helpful. > A friend recently inherited a small family of homeless Televideo 920 > terminals, but without any docs.

I believe the design of the 925 is quite similar. The 950s had a nasty habit of blowing the video drive board. There is a big electrolytic capacitor that couples the horitonal drive to the yoke and flyback transformer. It has been a while, but my recollection is that it is about 47 uF, 25 V, non polarized. There is a current of something like 3.3 aRMS flowing in that capacitor and it tends to get rather warm and hence dry out and short. Sometimes, the horizontal output transistor and flyback are taken out when the capacitor shorts. We eventally dumped the 950s when it became difficult and expensive to get the video drive boards. I don't recommend that inexperienced technicians touch the high voltage wiring. On older terminals, the anode lead to the CRT often gets coated with greasy dust. After using appropriate discharge techniques (discharge twice, several minutes apart for safety's sake), the wiring may be cleaned with alcohol. There is probably anti-corona paint on the CRT where the anode lead connects, so clean carefully. Radio Shack used to (I haven't looked lately) sell corona dope, otherwise you can probably find corona dope at a local TV repair supply shop. If you don't know how to discharge the anode lead, don't mess with the high voltage wiring. On TVI 950s, a video board that was about to blow would sometimes overload the low voltage board and cause false symptoms to appear on the logic board. -- Bill Mayhew NEOUCOM Computer Services Department Rootstown, OH 44272-9995 USA phone: 216-325-2511 wtm@uhura.neoucom.edu (140.220.1.1) ////////////////////////////////////////////////////////////////////////////// Path: utkcs2!darwin.sura.net!mips!samsung!uunet!news-server.csri.toronto.edu !helios.physics.utoronto.ca!alchemy.chem.utoronto.ca!system Newsgroups: comp.terminals Message-ID: <1992May6.200115.15557@alchemy.chem.utoronto.ca> Sender: system@alchemy.chem.utoronto.ca (System Admin (Mike Peterson)) Organization: University of Toronto Chemistry Department Date: 6 May 1992 20:01:15 GMT From: system@aurum.chem.utoronto.ca (System Admin (Mike Peterson)) Subject: Re: Televideo 910 In article <92120.230211WAF102@psuvm.psu.edu> you write: > > I need help setting the DIP switches on my 910. > I need to set it to: Full Duplu, 9600 baud, even parity, > 7 data bits, and 1 stop bits.

If the the terminal does not boot into the diagnostic screen the switches have probably been toyed with. I wish i could tell you which switch did what, but i had to use a hit-or-moreoften-miss strategy myself, since sharon industries could offer no information about the 970. Once you can enter the setup screen, the cursor keys select the option, the t key changes them (toggle, i assume), ctrl-r resets to default, and ctrl-s saves thems to nvram. The terminal does ansi, vt52, and and tek (4014?) graphics. I owned one for years and my only complaints were the lack of docs and the weight of the keyboard.

This does mean creating or coming up with 4 terminal types instead of 1, but you're more likely to take advantage of each terminal if you use what each offers instead of using a common denominator. Further, if the glitch is defined in the termcap or terminfo entry for that terminal, and the program you use is still drawing things incorrectly, it is that _program_ that is broken not the terminal or the termcap/terminfo entry. Unfortunately, it's quite common for Unix programs to work only with terminals that have no magic cookies or (even worse) to work best only with something that is vt100-compatible. >I've tried setting xmc# to various values and it only seems to agrivate the >problem.

I doubt you'll ever find a complete termcap definition for any but the least capable terminal.

You should consult the terminal manual to see if a given terminal really has automargins and then verify that on the actual terminal. If something displays wrong, again, you might have broken Unix apps. For various tests and invaluable info regarding creating your own 100% complete entries, I urge you to buy "termcap & terminfo" from O'Reilly books.

Thanks. Unfortunately, I've got this problem because we've got hordes of old Televideos which are being used for public displays (because nobody would want to steal them). And so... I'm making progress: I've fixed the problem with the box characters by redefining the terminfo entry to use normal (+-|) characters, and I've managed to get the standout code working by descending to generating the character sequences from terminfo information, and not using curses at all for that bit.

However, its Televideo emulation mode has one deficiency of importance when it is asked to replace a Stratus terminal: it does not support the second page of screen memory. The Stratus V102 terminal, as we have discussed here before, is basically a Televideo 955, but all 955's in V102 livery are equipped with the second page of screen memory. (The 2nd page was an extra-cost option for the stock Televideo product.) The screen memory commands are documented on page 22 of the "Stratus V102 Terminal Programmer's Guide" (R103) where "Escape" is the single ASCII code 0x1B: Display page 0 Escape [ 1 ; 0 } Display page 1 Escape [ 1 ; 1 } Display other page Escape K (or Escape J) The standard VOS 'v102' terminal-type definition (.ttp) setup assumes that the second page is there. The explanation given in R103: Page 0 is generally used for the text that is displayed on the screen. Page 1 is used to store data that is being held for later and perhaps repetitive display on the screen. For exam- ple, the Word Processing Editor's menu is stored in the second page of memory (page 1). When [MENU] requests are issued, the Word Processing Editor simply causes the terminal to display the second page and thus does not have to retransmit the entire screen. So, if the second page is not there, some operations with some VOS applications produce strange or no output. One of my colleagues asked DataStorm Technologies (ProComm's vendor) about the possibility of a new version that would support the second screen page, and he received no encouragement. But if you want to use the tvi955.ttp from "unsupported_ttps", then maybe you'll be happy with ProComm. But if you are going to use a non-Stratus terminal type, then you could just as well use the ANSI-type DEC VT100 or VT220 flavor performed by many other terminal- emulator software products. ...Richard S.

Do a text search to the last month or two worth of mesages in this newsgroup for TeleVideo, or try calling TeleVideo themselves and they might be able to point you in the right direction. -Blair Groves (blair.groves@canrem.com) ------------------ ------------------ ------------------ ------------------ Newsgroups: comp.terminals Path: cs.utk.edu!cssun.mathcs.emory.edu!gatech!newsfeed.internetmci.com !in2.uu.net!istar.net!news1.toronto.fonorola.net!news1.toronto.istar.net !news.toronto.istar.net!news.crso.com!canrem.com!blair.groves Distribution: world Lines: 33 Organization: CRS Online (Toronto, Ontario) Message-ID: <60.5685.2013.0N20AE58@canrem.com> References: <311F4B27.52CF@aifh.ed.ac.uk> Date: Thu, 15 Feb 96 13:12:00 -0500 From: blair.groves@canrem.com (Blair Groves) Subject: Televideo "Network Station"?

This device is a diskless XT that connects over RS-422 to a TeleVideo Personal Mini, which runs either InfoShare or an early version of Novell's Netware. With that connected, it boots DOS from the server, and gains a session to the file server, and presents a login prompt. It's based on the same basic platform as TeleVideo's 905 and 955 terminals, so the monitor/power supply/case could probably be retrofitted with a 905/955 logic board and keyboard, which would give you a much better (and more configurable) terminal emulation. -Blair ////////////////////////////////////////////////////////////////////////////// In-Reply-To: <891527940.15662.0.nnrp-02.c2de32c9@news.demon.co.uk> Message-ID: Date: Thu, 2 Apr 1998 11:30:44 -0500 (EST) From: "Richard S.

Terminal >servers won't do. If such a thing doesn't exist then it should be invented! Televideo 950s are approximately 1979 technology, built to communicate over asynchronous serial lines. My [former] employer, Stratus Computer, used to sell them (as model V101). Stratus stopped selling them around 1990 and dropped support for them in 1995. And Stratus is better than most vendors about supporting such older products. In case you haven't been following the chronology, in 1979 TCP/IP was still merely a figment of some researchers' imaginations. By the time TCP/IP was in use anywhere, the ANSI standard for terminal controls was well established (by the success of the DEC VT100) and Televideo's proprietary control sequences were on the downslope of popularity. I'm sure if you threw enough money at somebody, then such a thing could be cobbled together. Maybe a remote applet that runs on either an X Terminal or a "Net Computer". In 1990, IXI had a product called "X.deskterm", a package for integrating character-based applications into an X Windows environment. It included a number of terminal-emulation modules. There's a good chance that TVI 955 was among them. The old phone number used to be +44 (0223) 462131. I think IXI was bought by Visionware, which was itself later gobbled up by SCO. The question is, how much money are you willing to throw? Or what level of support do you require? You are asking to have somebody cobble together a variation on some old proprietary technology, where newer, standards-based technology that does more-or-less the same job exists. There's not a big market for it. ...RSS ////////////////////////////////////////////////////////////////////////////// Newsgroups: comp.sys.stratus,comp.sys.sun.admin,comp.terminals References: <3CD2B289.5040207@fcc.net> Message-ID: Organization: Stratagy Users Group Date: Fri, 3 May 2002 15:31:31 -0400 From: "Richard S.

Nadda. | What am I missing? Or maybe I have a pin-out problem? Has the V102 been known to communicate normally through that serial port? It may need a null-modem cable or adapter, since both the video terminal and the computer have DTE-flavor serial ports. On a Sun SPARC machine, when used with a serial-terminal console instead of a graphics "head", a serial "break" condition is used to revert control from the operating system to the OpenBoot PROM monitor. (Don't do this unless you mean it!) If the machine is being operated with a graphics head and a local Type-5 keyboard, the keychord Stop-A has the same effect (L1-A on older machines). A real Stratus V102 terminal (a.k.a. Televideo 955) should be able to transmit a serial-line "break" condition. The V102's second keyboard-setup menu (accessed using Shift-SETUP) does have a modifier for the BREAK key. The two effects of that menu setting: "BRK EN" pressing just the BREAK key sends the break "BRK DIS" you have to type the keychord CTRL-BREAK On the other hand, you didn't describe the configuration of your "Sun box". Its default setting might have been changed to ignore the regular "break" signal. The "Alternate Break" sequence, possible in Solaris 2.6, 7, 8, and (soon) Solaris 9, is CR ~ CTRL-B That's Carriage Return, tilde, Control-B, with at least one-half second elapsing between characters, and with the sequence being completed within 5 seconds. You can read about this in the Solaris man-page help system with these commands: % man kbd % man zs See also: http://www.stokely.com/unix.sysadm.resources/faqs.sun.html [STALE: as of 2007, see: http://www.sunhelp.org/stokely/2xmodem.html] http://www.cisco.com/warp/public/770/fn-tsbreak.html and I might as well mention: http://www.cs.utk.edu/~shuford/terminal_index.html ...Richard S.

From the keyboard, I'd say it was a Televideo 912B, although my manuals don't show any model which only got two lighter keys on it. The Return key changed into the mirrored 'L' shape for later models. There is a posting on Shuford's site from Mark Aitchison which lists the different escape sequences for quite a few of the Televideo models. If you get really enthusiastic, you could try making your way down that list, trying the sequences in local mode. If it does turn out to be a TVI-912, you can grab the manual from http://vt100.net/televideo/912b-om/ - Paul ////////////////////////////////////////////////////////////////////////////// [ http://www.cs.bham.ac.uk/research/poplog/doc/pophelp/tvi ] HELP TVI Aaron Sloman June 1982 --- TEMPORARY DOCUMENTATION ON TELEVIDEO VERSION OF VED -------------- There are two library files for Televideo terminals (unsupported). LIB * TVI is for model TVI 920C, emulating a VT52 VDU. LIB * TVI925 is for the TVI 925 VDU. For details on the latter do SHOWLIB * TVI925 To load it do lib tvi925; The rest of this file is concerned with LIB TVI. To use the TVI 920C version of VED it is necessary to do lib tvi; before you run VED. This takes a few seconds, but you can, instead, create a saved image to avoid frequent re-compilation. Use down arrow key to read on. LIB TVI caused real problems because the terminals don't correspond to the manual. I assume this is because of VT52 emulation. Note: If you use the full power of the Televideo terminal, which includes the ability to insert and delete lines (used for scrolling this window) you will find a terrible screen flicker. It seems to have an inherent design fault. You can overcome this by the following: true -> vednolineinsert; (which can go into your vedinit.p file if you use the Televideo often). The result will be re-writing of the whole window every time you need to scroll it up or down. -- KEYS ON THE TELEVIDEO ----------------------------------------------- The following assumes twelve function keys, F1 to F12, which transmit ESC ? CHAR. Then there are 4 more keys marked Char Insert, Char delete, Line insert, Line Delete. Above the keypad are three more keys, one simulating GOLD (ESC P) and the other two duplicating Char Insert, and Line Delete. !!! The four Arrow function keys work as on the Visual 200, and are left for large moves up, down, left, right, as with the Visual 200 version. The general plan is as follows Keys F1 to F11 work exactly as on V200. F12 = VEDEXCHANGEPOSITION (ESC P on V200) So: F1 = Delete line to left of cursor F2 = Delete whole of cursor line F3 = delete line to right of cursor F4 = Delete word to left of cursor F5 = Delete word to right of cursor F6 = Move in or out of static mode F7 = Mark as beginning of range F8 = Mark as end of range F9 = Move marked range to after cursor line F10 = Push current position onto VEDPOSITIONSTACK F11 = POP top of VEDPOSITIONSTACK - i.e. go back to that position F12 = Exchange current position with top of position stack. CHAR INSERT key = insert line above CHAR DELETE key = delete char under cursor (like CTRL-P) LINE INSERT key = insert line below LINE DELETE key = line delete (as does F2) The key with blue dot, above keypad 7 does screen refresh The next two keys duplicate the CHAR INSERT and LINE DELETE KEYS. Holding the FUNCT button down changes all keys so that they transmit CTRL-A, then the normal character (controlled by shift) then CR This means that CTRL-A can no longer be used for VEDSCREENLEFT However, VEDREADFUNCTIONKEY has been defined so that three CTRL-A's in succession will do screen left! The FUNC key has been used to modify the keypad, so that the numbers 1 to 9 with FUNC key depressed work exactly as on V200. I.e. the move cursor in 8 directions. For bigger jumps do ESC then key. E.g. ESC 9 does VEDCHARUPLOTS, and ESC 3 does VEDCHARDOWNRIGHTLOTS. The Comma and Dot, with FUNC do word left or word right. Instead of ENTER it is necessary to press FUNC and RETURN, or FUNC and ENTER (The rather silly ENTER key on the Televideo just duplicates RETURN!) FUNC a = go to top of file FUNC z = go to end of file FUNC g = REDO last command. FUNC - = REDO last command. (I.e. use key next to ENTER key) FUNC 0 = put cursor back on command line without removing previous command To extend the range of function facilities, copy [pop.lbi.ved]tvi.p, and edit VEDREADFUNCTIONKEY to suit yourself. The system version may be extended if there are good suggestions.
