>Post a digital pic on your webpage so we can look 'n' see? K.. but it will have to wait until tomorrow (I have to bring my camera in to work). Any particular shots you want? Front, Sides, Insides... posing in a nightie? I was able to find a "part number" on the main board. Claims to be a 980100-01 Rev D. I am about to hit WYSE's site to see if that gets me anywhere. While I am posting pics, I will post ones of my other terminal for another phone system, since ultimatly I want to get it replaced as well. The other one I am guessing to be a Qume of some kind (I have better docs for the 2nd phone system, and it hints at it being a Qume, but doesn't say a Qume what, or even if it IS one). The two terminals look TOTALLY different. (but the 2nd one isn't as big of a deal, since I am able to connect a laptop to it running a TVI-50(?) emulator). -chris <http://www.mythtech.net>

Sounds like the two PAL ic on the left side, under any zorro cards you may have installed, they have a nasty habit of running hot, and makingen the screen unreadable.

Possibly not. I have a DEC one that certainly does, but it's much larger than the TEAC ones, which fit under the drive in a small frame the same form factor as the drive. They're so small and thin that at first glance you might not notice there's an "extra bit". -- Pete Peter Turnbull Network Manager University of York

IDing WYSE terminal

by mythtech＠Mac.com

Is there a way to tell what type of WYSE terminal one is? I have a broken terminal that I need to figure out what kind it is, so I can connect a PC running emulation (or another terminal) to the system. The terminal itself carries only the name of my phone system (it is the operators terminal for it), but opening it shows a main board marked WYSE. But I can't find anything that says what KIND of wyse. Is there someplace is should be marked? It is possible to tell based on some of the chips? I also see some kind of a daughter card attached to the main board. Are these terminals custom programmable? Is it possible the phone system uses a stock terminal with some kind of custom additions (I sure hope not, but I have that fear, as the keyboard has some phone specific keys like Voice Mail on it... but I was really really hoping they were just regular keys and the system knows that things like "end" really mean enter the Voice Mail system). Anyone have any pointers for me about how to figure out what terminal type this is. Thanks (oh, and it should fit as on topic, since the only date I can find on the unit is a refurb'd sticker marked 1991, so it just had its 10 year B-day... at least since being refurbished, that and the phone system it belongs to was discontinued about 15 years ago) -chris <http://www.mythtech.net>

vintage schematic for academic use (fwd)

Can anyone help Jeremy? Please respond to him directly. ---------- Forwarded message ---------- Date: Wed, 10 Oct 2001 13:04:14 -0500 From: "Nolle, Jeremy" <JNolle(a)rgare.com> To: "'archive(a)vintage.org'" <archive(a)vintage.org> Subject: vintage schematic for academic use Hi! I am a student at Washington University in St Louis, and as a project in my EE class I would like to turn an old laptop into a standard VGA display. I have currently access to several Toshiba displays (4400c, 4700ct, etc) and can get Zenith displays also (433 vlps) from the mid 1990s. Do you have (know where to find) schematics for these displays? I also have the mainboards from these laptops, as well, although I dont think that will help. I will be building an A/D controller, and need to get the schematic before I start. Thanks!

ArcNet and the Pursuit of Multiple Topologies

On Oct 10, 15:45, Iggy Drougge wrote: > Was DIX really the original Ethernet? Wasn't that 10 Mbps and all? Depends on your definition, I suppose. I was being a bit lazy (ie inaccurate :-)) when I wrote "original DIX Ethernet". The first system called Ethernet was developed at Xerox PARC, and that was 3Mb/s. It was originally called "Alto Aloha Network" but the name was changed becasue it would work for any suitably-equipped machine, not just an Alto. The first proposed cross-platform *standard* was the DIX standard, which was 10Mb/s. -- Pete Peter Turnbull Network Manager University of York

All of ours used 50/125. It has better performance, and it was the standard when ours was installed. A lot of other UK installations were done later, and used 62.5/125 because that was more common in Europe at that time -- but they're now regretting it as 50/125 has become the standard for Gigabit. -- Pete Peter Turnbull Network Manager University of York

I have a CHANNEL-3Mbps card for an S/370 here. You're right, Dave & Sridhar... from: http://www.baylor.edu/~Sharon_P_Johnson/etg/ethernethistory.htm 1972-The first experimental Ethernet system, Alto Aloha Network, was developed by Metcalfe and his Xerox PARC colleagues. It was designed to interconnect the Xerox Alto, a personal workstation with a graphical user interface, and linked Altos to one another, and to servers and laser printers. The data transmission rate was 2.94 Mbps [Spurgeon]. Regards, -doug q

Slightly OT: What to do with a DEC 3000/300?

I *need* to > consolidate my collection & am downsizing machines which I will never have > time to tinker with...) If the DEC 3000/300 is anything like a DEC 3000/300LX then you should be able to get some 72-pin true parity SIMMs and upgrade your RAM. If you can get it up to a minimum of 112MB it should work great. If you can get it up to 96MB it will work OK. Less than 96MB, and it will work, but will probably do a fair amount of swaping. OpenVMS V7.2 won't even load if you've got less than 64MB RAM. It's definitly a good VMS box, so I say keep it, get some more RAM for it, and play with VMS on it. I used my DEC 3000/300LX as my OpenVMS server for a while with a BA350 chassis attached to it for disks. Zane

At a place I used to work we were setting up a new raised floor. The (licensed!) electrician that was setting up the new UPS was leaning with his hand against one end of the bank of batteries. He leaned down to tighten the nut on the other end of the bank of batteries with a metal socket wrench. The UPS was about the size of four large refrigerators side-by-side, 90% of which was filled with batteries. He nearly died and spent quite a long time in the hospital. The investigation kept the area closed for almost a week. -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

Is flow control enabled on the terminal? I assume you're using a DB25 adapter at the other end of an MMJ cable. Try turning off flow control in the communications setup menu and shorting pins 2-3 on the connector. At that point the terminal should echo what you type back to the display. If it doesn't, you might have a toasty RS232 line receiver in your terminal. -Dave -- Dave McGuire Laurel, MD

New toy, some questions..

by technos＠nerdland.org

For a birthday present, my girlfriend tracked down and bought me a Radio Shack PC-1 with cassette adapter (Both in orig boxes!). It compliments nicely the PC-2 and plotter I already have. After addition of four 1.35V zinc-air hearing aid batteries, it's humming along on my desk counting up by eights.. Does anyone still have software for this beastie? My other Q is converter programs. wav2bin (Sharp calc converter) supports it fine (its just a rebadged PC-1211) but the companion program bin2wav does not. Do other conversion programs exist? Are there any that run under *nixen? Any with source? I have tried contacting the fine folks at www.pocketmuseum.com, as they seem to be the author of the software mentioned already, to no avail (broken email addy). Jim
