I am clearing these out of my stock: 4 are beige, with no PN on the back. They have a small RJ9 type connector. 3 are missing one or more caps. 4 are dark on top, and beige on the back. There is no PN. These have the save telephone style connector. All are complete. These have not been tested or cleaned. I would love ro send all 8 of these to 1 person J Pics can be seen here: https://drive.google.com/drive/folders/1GvCajMJk1EeSLjpGnl4LsGbJPH6l-B2H?usp =sharing Cindy Croxton Electronics Plus 1613 Water Street Kerrville, TX 78028 830-370-3239 cell sales at elecplus.com --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Keyboard "enthusiasts"

by ggs＠shiresoft.com

?are the bane of my existence and should all rot in hell. Sorry, I just received an email from a ?keyboard enthusiast? who was looking for various IBM 327x keyboards and wanted to know if I could help him and I needed to vent a little. I sent him a polite ?no way in hell? response but I?m still angry about it. These terminals are hard enough to find. And more often than not, the keyboard is missing because some ?enthusiast? thought it would be cool to convert it to a PC keyboard. ARG! And of course the keyboards that they want are the ?typewriter? keyboards (all of my 3278 terminals have the ?data entry keyboard?). TTFN - Guy

Ethernet cable (Was: Sun3 valuations?)

> From: Grant Taylor > I can fairly clearly see the RG-8/U on the side of the cable that David > is holding ... Sure, there was probably a better alternative that came > along after, with better shielding and marking bands. You keep mixing up the 3 Mbit and 10 Mbit. _They were not the same_. (I _really_ need to retake those photos with a ruler in them...) The stuff with better shield, marking bands, etc is 10 Mb; it's about 1.05cm in diagmeter. The black stuff (the stuff Dave is holding in the video) is 3Mb; the piece I have is .95 cm. The video, perhaps confusingly, shows a mix of 3Mb and 10Mb gear. The small aluminium sheet transceiver (the one attached to the black cable when Dave is doing his spiel) is the 3Mb one; the others are 10Mb. Noel

IBM 3101 keyboard - was Re: Keyboard "enthusiasts"

by ian.primus.ccmp＠gmail.com

Well, let me know if you find another one. Or, if anyone else has one they'd be willing to part with for reasonable money. The regular 3278 type keyboards won't work on an IBM 3101 - and those are a lot more common. The one I need looks like this: https://i.imgur.com/1Cz8hMi.jpg It has the configuration switches to set the baud rate and such under that panel at the top. Without this particular keyboard, the terminal I have is useless - you can't even have it just receive/display data, since the configuration switches are in the keyboard.

Don't get me started. I collect terminals. Missing keyboards is a perennial problem, but it's gotten WAY worse in recent years.

Keyboard "enthusiasts"

> From: TeoZ > mouse (optical mice are better then the old ones with balls). I even > keep old ball mice around ... and those do wear out) Huh? I've got old ball mice I've been using for years; they don't wear out. The wires do get flaky after a long period of use (at which point I stop using them - easier to switch than to chop an inch off the wire - the issue is where it goes into the mouse), and you do have to clean them regularly, but other than that...

Ethernet cable (Was: Sun3 valuations?)

by jnc＠mercury.lcs.mit.edu

> From: Grant Taylor > According to the following page, it was not RG-8 cable ... As such it > was purpose built. The 10MBit cable, yes; it was custom (you can see 'Ethernet' printed on the chunk in the picture). (I'd forgotten about the black stripes! I'm not sure we really bothered to follow that.) The earlier 3Mbit I'm not so sure about - that has the air of standard commercial coax. I wish there was a picture of a 3Mbit transceiver, clamp-on holder, etc! Does the CHM or LCM have them with their Alto stuff? Noel

More Alto remarks

by mark.kahrs＠gmail.com

I had forgotten about OrBit. According to this very nice document: http://xeroxalto.computerhistory.org/Indigo/Spruce/documents/.orbitguide.pr… ... the Orbit hardware was 4 cards in the Alto II backplane. As I recall, the SLOT interface was only 1 card; it was connected to a slower speed printer. The only modification to the Alto: wire wrapping the task signals (don't ask me how I know...) And yes, I agree, only the high bandwidth I/O used tasks. The use of tasks and "time sharing" the Alto processor innards is one of the Alto's real treats.

Apollo Software

by bill.gunshannon＠hotmail.com

Is there any interest or value in copies of SR7.0 "Aegis" or should I just scratch them and add them to my other 8" disks? (Yes, I used to have an Apollo in my house!! Made a great heater during those long cold winters.) bill

eBay: PDP-11/34 chassis available

by jnc＠mercury.lcs.mit.edu

So this lot: https://www.ebay.com/itm//192436422371 claims to be an -11/04, but there are no boards in it. However... the first backplane (of two) is a DD11-P, which is the backplane for the /34 as well as the /04. And there are /34 CPU boards available on eBait at the moment. Pick up a pair (the seller will probably negotiate on price), add an M9301/M9312, and a DL11 or DL11-W (also available), and away you go. Noel
