What about TSX+ ? was Re: Where can I get DECmail-11?

by GOOI＠oce.nl

I hate to do this, but this will be my first "me too", Lyle. I have the original TSX documentation binder and release notes of what is now available on bitsavers, but no software on whatever media. So, I am certainly interested! tnx, - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org]On Behalf Of Zane H.

Commodore 64-sx Keyboard getting stuck?

by dwight.elvey＠amd.com

Hi That sounds similar to the keyboard on my Sun at work ( the one I'm typing on now ). About 3 years ago, I spilt Dr. Pepper on it. It immediately stopped working. I took it apart and washed the layers one at a time and dried them. It is still working today. I can imagine that replacing missing traces would be a little more difficult. I'd think that the current through most of the wires is quite low and one might try using some of the repair stuff for windshield heaters. If that didn't work, a last resort might be to use some small wire wrap wire and melt a channel into the plastic layer to keep from deforming the stack of sheets to much. Just some thoughts.

Commodore 64-sx Keyboard getting stuck?

by florit＠gmail.com

Hi, I pulled out my 64-sx out of the box it's been stored with in anticipation of getting my JiffyDos upgrade installed into it. To my dismay, when I plugged it all in and powered it on, the keyboard wouldn't work properly. Any of the keys have to be pressed multiple times (3 to 10 times) in order to get the character to show up on screen. Any suggested remedies? I'm wondering if the keyboard contacts are just a little dirty and need a little cleaning, but I wanted to check with the gurus before prying it apart.

Getting loose and oxidizing make for a hot connection when current of any kind goes through it. Add some flammable material and you have a nice bond fire. What were they thinking? Dwight

DEC Microfiche question

by aek＠bitsavers.org

> Very Handy! I suppose you have to position it manually for each page. nope. it should be step and repeat for the entire sheet, once I understand how to set up all the parameters. the device is not a fiche reader with scanner bolted on. it is an x/y table with adjustable lens and imaging array. there's a pci motherboards buried inside running DOS, which we backed up a couple days ago. here's a picture of one (it's a LOT bigger and heavier than it looks...) http://www.cadcam.org/pscnmekel.php > How many sheets do you have waiting to be scanned? thousands..

DEC Microfiche question

by aek＠bitsavers.org

Pardon my ignorance - but some of the sheets in the manual are horizonal/large. Were the fiche images larger or did you have to enlarge them? (I have some fiche - but they are all the same size images). -- Computer Output to Microfilm (listings and such) will have the same size frames, but documents might not, since they have foldouts. This particular document was all post-processed by hand, scanning oversized frames and cropping to 8x11 or 11x17 effective size. It took about two hours to reformat all the scans.

wild and possibly idiotic idea- what do you think?

by compoobah＠valleyimplants.com

The recent discussions about unsupported software led me to think about old O/Ss in general. It seems that possibly one of the reasons that companies are not releasing them is due to the amount of work involved in contacting all the other groups who licensed bits to the software (e.g. AT&T for UNIX) (I have no idea how these agreements were set up, so it might not be an issue, but . . .) Anyway, to the point- perhaps if some group were able to decide on a list of systems they really want to see available, and secure the permission of other interested parties, then we could see some of these older software available for free to hobbyest users (stuff like DOMAIN/OS/Aegis, older MCA AIX, IRIX). I know that in some cases (PERQ et al.) it will be difficult to figure out who to contact, but some we could just read of the copyright screen. Enough drivel, dumb idea or not? -Scott Quinn

Another DEC KL8-AA Question

by rigdonj＠cfl.rr.com

FIRST. This is NOT the panel that I was describing in my earlier question about the KL8 stuff. This is an entirely different panel. Does anyone recognize this panel? It's marked KL8-AA M8319 on the back. But it's marked by hand so that may not be accurate. It has two ribbon cable connectors that I'm guessing connect to one or two M8319 cards. It also has eight Mate-N-Lock connectors marked J2 through J5 and J7 through J10. It also has eight DB-25M connectors marked P1 though P4 and P5 through P8. Just as a guess I'd say that it can use the cables with the Mate-N-Lock connectors or cables with DB-25F connectors and it looks like it can handle a total of eight serial data lines. Anybody know if that's correct or what machine it's for? Joe
