My Mac+ has a stable screen :-)... Yes, yes, that is the correct way to fix it (I have done many myself)... the "whack it" comment was a tongue in cheek remark, since at one point, that was actually an apple authorized temporary fix (until you got tired of it enough to bring it into a service shop and have the joint resoldered... since back in that day, you were supposed to open your own mac... although I ignored that starting with my 128k). At one point, I even found a tech note about doing it, although, they refered to it as "tapping forcefully". -chris <http://www.mythtech.net>

> It actually got all its data over SCSI. I suppose its main application was the > very oldest compact Macs which didn't even have any PDS slot. The very oldest Macs didn't have SCSI ports... However, a company called Dove had a board that plugged into the ROM slots, and into which you then placed the ROMs, that provided a SCSI interface for the Mac 512k/512ke. They also had a memory board that had the way of interfacing to the main board... it had funny-looking sockets that "clamped" down on top of the existing DRAMs and which provided enough to bring a 128k Mac up to 512k or a 512k Mac up to 1MB. I still have both boards... -dq

And they could (and indeed did) talk more or less directly to a lot of high-end lab equipment, especially HP's, although admittedly not quite at the 10Mbps rate of today... That is indeed what it is, Joe; if you actually want to use it, the DIP switch selects the unit address (usually 4 for a printer) and (if I remember correctly) the CR/LF and all-caps options. Still have a couple in fact, as well as a 1450 serial version; used one for many years to let my 8032 talk to my Centronics 101. mike

AlphaServer 1000A & EISA Config

by bdwheele＠indiana.edu

It is slightly off topic, though I hadn't seen an eisa card for what seems like a decade :) In any case, I recently got a 2nd hand AlphaServer 1000A with no disks. I put an EISA SCSI card I dug up in the machine, but its wanting me to run the eisa configuration utility. After scouring the net, I found one that would come up, but only if I burned it onto a CD. Now its complaining that It can't find a configuration file for my system board. Grrr. I suppose I'm glad EISA is dead, but...it would be nice if I could get this silly SCSI card to work. Any thoughts/hints/suggestions? Brian Wheeler bdwheele(a)indiana.edu

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.

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 think I might have a 5150, 5160, and a 5170 around as well (actually, I KNOW I have a few 5170's left... but only two or three, the rest were dumpstered, or stripped for parts). 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>

>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.
