DEC stuff is so cool! They were sneaky and smart!

> Their Idea of a Self Shorting Card slot blew my mind! Never saw >anything like that in my 31 years of life! Remove the STP and what you >got? a standard WORKING Vt100? No soldering! No trace cutting? and I love >this! No DIP Switches to switch! Many years ago, I took one of the 20ma current loop options and added a DPDT switch to it, the four wires from the switch snaked to a piece of a two-sided card which slid into the stp slot of the VT100. With the 'card' (only two fingers wide) inserted in the stp slot, the switch allowed me to switch between the EIA connector on the back of the VT100 and the 20ma current loop connector... I still have the modified option...

When I got started the part number belonged to Sprague, now Allegro Micro sells them - see http://www.allegromicro.com/ If you fetch the 2803 data sheet, you'll see that it still proudly claims that the inputs are DTL compatible :-). -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Vt180, whats the story here?

Vt180, whats the story here?

by allisonp＠world.std.com

<One thing I didn't mention is that there's a pin on both the AVO and <STP(?) connectors that's grounded when the appropriate board is <installed. This tells the VT100 control software (there's an 8080 or some <such in there, BTW) that that board is present, so it can report it to <the host. It's actually a DIP setup on the AVO and main board of the VT100. Stp for the most part was null functionality save for the printerbuffer cards. <Oh, quite likely... People on this list have all sorts of things... I <have a real VT105 (for my MINC system, for which it is the 'official' <terminal), but I am _not_ pulling the waveform generator from it. You forgot the VT103 that was a VT100 with AVO using a cost reduced card. I ahve one or two of those loose. <> > Composite in is strange. You first have to extract the sync from the <> > composite out socket, and lock an external video source to that. You ca <> > then feed the output of that video source into the composite in socket, Older video sources like cameras were deigned to be genlocked off somthing else and had two cables (the one I'd seen) and the sync return was usually >from the output of the GENlock/timebase to the VT100 and a TEE connector seemed to work for that. Should work for color as well. Allison

Vt180, whats the story here?

by allisonp＠world.std.com

< First a short summary, Something I have been giving for <awhile, I got a free Vt180 terminal. AT least Thats what It says on <the front. but on the back on the nameplate it says its aa Vt100-AA! I <am wondering if the AVO and the Secondary Processor part (STP) was <added later on. It works GREAT as a vt100 but I have ran into a few Typically they were or could be and the VT180 was some complete or as a VT100 upgrade. <brick walls trying to find a EK-vt100-UG Vt100 Users Guide. I can order <it from Digital/Compaq for $25 but I rather not dip into my grocery <money for a technical manual. I have not found out anything on how <to set the printer up on it. or how to use the Vt180 part of it. or <for that matter, how do I RIP that OUT! if I cannot get a boot disk <for it... its worthless anyway. Here is my questions. Please help me <best you can here: < 1. what is Advanced Video Option (AVO) and how do I use it? AVO permits 132 character lines by 24 lines where without it you limited to 132 by 12. It also adds video attributs (things like bold(bright), blink, underline and more). < 2. If the STP is the VT180 part how do I REMOVE it! *if I want <plain Vt100, while maintaining AVO) The STP is a seperate card that plugs in. The AVO is larger and has several 24 pins sockets. < 3. How do I use a printer on a VT100 and how do I set printer <baud rates and parity, Stop bits Different for plain VT100 than VT180. Vt180 has a utilitiy on the CPM boot disks. < 3. What are the part numbers for the manuals I need for this <sucker? I know of the EK-VT100-UG and the EK-VT100-RC but what do I <need for the advanced video option? STP (VT180? part) If you have a VT180, you have AVO as it was a required option for VT180 installation. < 4. What is the Graphics option? can I still get one? is that <for bit mapped graphics? howis it used? can the graphics be used via <Linux with graphics display utility or a plotting program (gnupplot). The graphics option was/is the VT125 upgrade. That can be combined to make a VT185 but the STP card for that config is really rare (I have one of the few). Nominally VT180s were not used with graphics option. The VT125 does two modes of bit mapped graphics, REGIS and SIXEL. the latter being a raw bit transfer and regis being a higher level plotting like language. < 5. can any of this info be located on the internet? Do I need <to go hungry by ordering over $200 in US dollars worth of manuals (I <only get $686 each month due to my legal blindness, that goes for <rent, Electric, Gas, phone and food. My rent is $350.00 btw. I'm afraid due to copyright and shear volume it's not on the net. < 6. who has the sticker (in sticker form) that goes on the <bottom of the vt100 keyboard showing the setup B screen and I/O toggle <possitions. DEC! It would be easier to get a keyboard for vt100 that does have that. < 7. How do I make the Needed cable to connect to the external <floppy drive unit? Db37 to Db25? what is the pinouts or wiring to <make this cable. I can give you the pinouts, I also have the cable sitting here to send between emergencies and other firedrills. ( I keep win boxen going). < 8. Since it has Composite In and Composite out. Does it have a <built in genlock allowing me to at least use the Vt100 to do titling <and captions; then sending the output to a second Video Recording <unit. if titleing is not possible, what is Composite video IN for?? Yes. It's use for that was a not often used feature but for those that needed it there were few options. < I tried to find this info for over 2 weeks, on Webcrawler, <Infoseeek, Lycos, Altavista, Lycos (ftp search), Ask Jeeves, hotbot and <what I have gotten is very sketchy at best. All I really NEED at this <time is a a copy of the needed manuals in either Postscript or PDF <format. or good ole HTML.. Finding the pin outs of the Vt180 cable are <non-existant, as is sources of Vt180 boot disk images. The vt180 was early 80s. One thing about the great WWW, if it's old, it aint there! < While we are on the issue of DEC stuff. Who has the full list <of the Control Codes for the Rainbow 100's terminal mode? How come <when I fire up CP/M Modem7 or 8? I can use the Previous Screen/Next It's a long list. The VT100 was the ansi terminal standard! All others were copies. <Screen keys and yet in the ROM Vt100 emulation Neither key works? Is <there a good program for CPM 86/80 that allows the use or the extraa <keys to be sent to Linux? such as HELP, DO, HOME, Insert, Delete Next <Screen and Previous Screen? what is the Ansi codes sent by these <keys?? I need something that handles 9600 bps with proper flow <control. the "Modem" program for CP/M does NOT seem to work well at <9600 as it drops characters often. Common case. Vt100 and vt180 software wwill run fast (19.2) _IF_ the other side and the modem understand X-on/X-off flow control. Even the base VT100 will not run at 9600 without that. I'd bet the linux Driver supports that but, it's PC based/biased so it's concept of slow maybe 38.4 which is not the way it was in the 1980s. IF there is no flow control, 2400 maybe 4800 is the limit then. Allison

PCjr E-mail client

by austinh＠ibm.net

Greetings I have a PCjr which I would like to use as an E-mail client. Are you aware of any software which I could use via my ISP (formerly IBM and now ATT worldnet). I also have PCjr hardware for which I would like to find a good home. Thanks in advance for help you can provide. Hal Austin Staatsburg NY
