Hey folks. It is likely that I will be driving an empty 24' truck to the DC area from the Tampa, Florida area within the next week. It has a lift gate. I would like to defray the cost of the truck somewhat...If anyone needs anything hauled along the 75N->10E->95N route, please contact me off-list. -Dave -- Dave McGuire Laurel, MD

I haven't powered it up in years. The only reason I didn't pitch it is because it IS a genuine IBM monitor (the 5151), and I didn't want to seperate it from its PC... which I wanted to keep because it was the first "IBM PC". >Is the line vertical or horizontal.

I am fairly sure it is vertical. I remember when it started to die, I did the Mac Plus analog board fix for it (whack it on the side), and that would bring it back for a bit. Finally it just stopped coming back, and stayed as a bright line. Humm... maybe in November I will pull it out and see if I can get it running.

IDing WYSE terminal

>If the daughtercard is indeed an RS422 interface, as someone >suggested, an ordinary RS232 or RS423 terminal will probably not work. Thanks to a link I found pointing to a reference page on wyse's web site, I have found out MUCH more info on this. Yes, the card is a RS422 card. Wyse even specifies that the ONLY company that it was made for was Isoetec, and they give the part number on it (and specify that replacements have to be bought thru isoetec). They do imply that it can be fitted on a standard wyse 60, but don't come right out and say that. > RS232 and 423 are single-ended interfaces, which means that each signal >consists of one wire plus a common ground connection. RS422 is a >differential system, where each signal has a positive and negative >connection. If your system is intended to connect to an RS422 terminal, >you'd need to do some hardware hacking to make it work. This suddenly makes all the sense in the world as to why my laptop can't connect to it. My laptop just has a standard RS232. I will probably have to try my Mac as it has an RS422 port on it. Otherwise, I am fairly sure I have a 422 serial card for a PC, I can always lug a whole PC to the site (it is at a different office, so hands on tests are hard to do... I make a list of things to try, and do them all in one visit) >Do you have any >information on the pinout of the interface? the Wyse link I came across has some info on it. IF I can track down the tech manual for the phone system, and IF it is like the manual I have to my 96 phone system, then it will have lots of tech info on pinouts... but so far I have been unsuccessful in finding a 66 techmanual :-( -chris <http://www.mythtech.net>

I don't think my 5150 works, but it is an original "IBM PC" (I know the matching monochrome monitor for it is broken, just displays a bright white line down the middle). I would have to search and see if I have a 5160, or just XT clones (again, they might have all been dumpstered). Yup... sitting on the other side of my desk is a 5170, the case is open, and it is on its side, currently supporting the Wyse 60 terminal I was questioning (and making the 5170's video card bow pretty bad under the weight of the terminal). I know, some people might be cringing at my abuse of it... but the ATs are worthless to me (outside of the fact that you can stick a pentium baby AT logic board in it, and reuse the case and power supply... I think that is where most of my 5170's went) -chris <http://www.mythtech.net>

IDing WYSE terminal

by mythtech＠Mac.com

Thank you everyone for your help. It looks like from pictures I am able to find (or was sent links to) that it is indeed a Wyse 60. I think the tell tale part is the contrast slider on the front bottom right of the screen (and the matching ID plate on the left side). So now I am on the hunt for a cheap replacement (looks like ebay has them around $40), where I will open it, and see if the daughter card is installed, if not, I will transfer mine. I also have a lead on a wyse 60 emulator to keep on the back burner for when my replacement terminal dies too. Alas, I am still stuck on the Qume one, but at least I know what Qume it is, and that one isn't half as important to me, as I can interface with that phone system thru a programmers back door running an old copy of ProComm Plus, so if the terminal never gets replaced, the receptionist just has nothing cool to look at during the day. And the #1 thing I learned from all this... when taking digital pictures, don't put your $2000 DV Camcorder down on something without verifying that it is stable and won't tip over (I caught the camera mid fall thankfully... now I am out looking for the cheapest, crappy digital camera I can find, so I can return my good camcorder to its bag and use it only when shooting movies like it was intended) -chris <http://www.mythtech.net>

IDing WYSE terminal

by mythtech＠Mac.com

>Post a digital pic on your webpage so we can look 'n' see? Ok... pics are up (sorry, no risque terminal pics). Go to <http://www.mythtech.net/terminal> There are two terms there. One is a Wyse something (maybe a 60 based on pics I just saw on ebay). The other is a Qume, that I am fairly certain is a Qume QVT-108 (seeing as that is silk screened on the main board). Both have some kind of a daughter card. Are the cards normal or are they some custom programmable thing to give the terminal special abilities for its used application. The Wyse terminal is from an Isoetec EZ-1/66 phone system. The Qume is >from an Isoetec EZ-1/96 system. If people can ID these, are there any recommendations as to where to get these terminals CHEAP (I saw some Wyse 60's on ebay for about $40, but I can't find any Qume QVT-108s). If terminals aren't available, does anyone have a recommendation of emulation software I can run. Thanks muchly -chris <http://www.mythtech.net>

If the daughtercard is indeed an RS422 interface, as someone suggested, an ordinary RS232 or RS423 terminal will probably not work. RS232 and 423 are single-ended interfaces, which means that each signal consists of one wire plus a common ground connection. RS422 is a differential system, where each signal has a positive and negative connection. If your system is intended to connect to an RS422 terminal, you'd need to do some hardware hacking to make it work. Do you have any information on the pinout of the interface? -- Pete Peter Turnbull Network Manager University of York

Avoiding SCSI Problems

Jeff, I have a data file on SCSI that I'll try to access sometime soon that may help you avoid problems that can arise when integrating SCSI. I had a link to it, but so much time had passed, it didn't seem to be there anymore, but I had also downloaded and saved it, just not on this system and drive.

Hmm -- my personal experience is that, unless the machine is already junked-up with a random assortment of TV and radio tuner cards, video accelerators, SoundBlasters and DVD decoders, SCSI is easily added to a motherboard with onboard IDE ports. I've personally built a few dozen of them, using both IDE and PCI SCSI controllers. What sorts of problems are you encountering? Glen 0/0

I have seen this happen MANY MANY times with PC keyboards, so maybe my findings apply. In every instance that I have found it, it is beacuse someone spilled either soda or coffee into the keyboard, and the pads were sticking. The key would register when pressed, and then when released, the pad wouldn't pop up right away, instead it would "peel" up, and cause a 2nd (or sometimes a 3rd if it was sticky enough) registration. Opening the keyboard and washing with alcohol or contact cleaner has always fixed it for me. -chris <http://www.mythtech.net>

We have an IBM 5110 with a serial adapter and have recently verified that the tape drive is operational. We are, however, missing the software cartridge for the serial adapter. Does anyone have a copy who would be willing to make a copy? We can supply a blank cartridge and pay shipping costs. -- HBP

IDing WYSE terminal

by mythtech＠Mac.com

>It looks identical superficially to my WY60. Though yours is much whiter on >the picture. Mine is grey, much the same kind of grey as Atari STs. It is actually greyer than the picture makes it out to be. Not being familiar with the Atari you mention I can't say if it compares, but I would say it is a good shade darker than it looks. It is probably close to the "platinum" window background color of MacOS 8 and 9 (if that is something you are familiar with). It is also WELL used, and the receptionist is was in front of cleaned it daily with rubbing alcohol and lysol for about 10 years before I found out... I am sure that lightened the color quiet a bit (although, it could have been worse, it took me a while to track down why one booth's phone kept shorting out... till I caught one of the interviewers pouring water on top of it to clean it before they started their shift!). -chris <http://www.mythtech.net>

IDing WYSE terminal

We have an >Executone phone system at work and it uses what appear to be standard Wyse >terminals (just like the pic), however they are modified for 422 in order >to handle the distances from the terminal to the switch. Can I safely put the daughtercard into a stock Wyse 60 and get the same functionality? What is the max distance for RS232? Are there any other real differences? The Wyse was stationed only about 50 feet (cable wise, crow flies about 8 feet thru a wall) from the KSU. Is that close enough that a stock RS232 based Wyse can reach? My Qume system is a different story, that is about 300 feet cable wise >from the KSU. (Although, it might be possible that the one in the Qume is fried, that terminal "works" it just doesn't pick up anything over the serial port... it stopped working when the phone pole in front of my building was struck by lighting, and due to poor grounding on the part of the phone company, half my phone system was fried, including the terminal... BUT... that gives me the idea of pulling the daughtercard from a 2nd one of the Qume's I have that has a bad powersupply... or was that a screen... humm, if it is a screen, maybe I can just mix and match and get one working) I would think the Executone terminal you have is fairly similar to the Isoetec I have. Executone bought Isoetec many moons ago, because Isoetec had better designs and systems. Most of the executone systems released after the buyout have been based off Isoetec designs/ideas. -chris <http://www.mythtech.net>

ArcNet and the Pursuit of Multiple Topologies

> I think you'll have trouble if you use anything other than 63 ohm coax... The cable is designated RG-62, but it's 93 ohm cable. Cards could be connected to an active hub or a passive hub. Passive hubs required 93-ohm terminators on the unused ports. But with an active hub you're all set. I have a couple of cables with BNC connectors, and I think a few left-over crimp-on connectors that you're welcome to have for the cost of shipping (or pick up in Berkeley, CA). Write to me offline. I got rid of a heap of arcnet stuff last year, alas. I think it's all at the Alameda County Computer Resource Center :) By the way -- how about DVD's via pneumatic tube? Now THAT is a high-bandwidth medium. I can sell you some pneumatic tube equipment too :) Brian

by rigdonj＠intellistar.net

I recently picked up a box called a "ADA 1600 Pet Printer Interface". It's a box slightly larger than a pack of cigarettes with two cables attached to it. One cable has a Centronics type connector on it and the other has a small circuit board with both a male and female 24 position card edge connectors on it. Is anyone familar with it or does anyone know which model PET it's for? Joe

Research Machines Information

by Simon.Hardy＠hemel-hempstead.sema.slb.com

Hi, I am looking for any information or resources relating to the UK based Research Machines 380Z and 480Z products. These were Z80 based micros, mainly used in UK schools during the mid-eighties. I have a 480Z in my collection, but it isn't 100% operational and I really need service information to enable me to track the faulty component.....Can anybody help with any information about these machines, so far all I have are a few collector/museum web sites.. Now I've asked my question, a little about myself. I am based in the UK and am interested in collecting 8 and 16 bit microcomputers from the late 1970s through to late 1980s. I have managed a reasonable collection of hardware and software and am in the process of cleaning/restoring the hardware and then preserving the software.

IDing WYSE terminal

>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>

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>

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!

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
