Tektronix Smalltalk (was Re: Making perfect Keytronic replacement keypads)

by spacewar＠gmail.com

Though Tek had other workstations that might have run Smalltalk, such as the 4300 series. The 4404 family originally ran a Unix clone whose name escapes me, but switched to UTek, derived from BSD 4.2. My hazy memory suggests that UTek 1.x might have been the clone, and UTek 2.x and later BSD.

replacement Keytronics keypads

by sales＠elecplus.com

I called Keytronics, and they said they have not made these since 1992 or 1993. They gave the name and phone of Mil-Key in WA, 509-891-6425. They said they MIGHT still have some available there. They also said Cherry capacitive keyboards use the same technology, and are still in production. Last tidbit of info, she said these foil and foam pads are also known as "deccofelt pads".

Old FTGH post? NoVA Equipment?

by jon＠jonworld.com

All, I was talking with someone a month or two ago about picking up some old Sun gear. They were in NOVA and I was planning on swinging by, since I'm in DC for work (and I drove out fro IN.) .... who was I talking to? I can't find the person's contact info or even a list of what was available. I know they posted here about the stuff. My brain has turned to swiss cheese. I want to say it was like a SB2000 or 280R or V240 or something along those lines. Thank you! -- -Jon Jonathan Katz, Indianapolis, IN.

It was one of those situations where I had to have it, but had no use for it! Dug it out to play with, but it doesn't seem to power on. Anything special to get this thing to turn on? I'm assuming the PSU doesn't work, or has issues, but I've not tried to figure it out yet. Just wondering if it won't turn on because there is no tape loaded, etc. There is probably something wrong with it, but thought I'd ask. Whose drive is it? DEC didn't make any 9-track drives themselves. I looked it up, and it looks like a Cipher. We had one of those direct from Cipher, and it was a total piece of crap. You had to open up the top and manually help it to thread, and as the drive powered the NCR SCSI adapter hung on the back, you had to leave it powered on all the time to not hang the SCSI bus. About every month or two, a read channel chip would die. We got a bunch of the custom chips from Cipher, but it became too much hassle to replace these chips constantly. The Cipher would definitely turn on without a tape, but I guess there's just a power LED. The only way it knows there is a tape is to try to load it. Jon Jon

Making perfect Keytronic replacement keypads

by barythrin＠gmail.com

Right but naturally who would have thought that a bunch of fanatics would be trying to use the hardware after 30 years or that the foam would even do that. I would have never expected that black tar to show up if i hadnt had to clean it up or hear others experience it as well.

IBM 8" Floppy Cartridges?

by me＠GarrettMeiers.com

Does anyone know what systems these types of cartridges were used in? I have 10 of these, and they are all filled with IBM 8" Floppies as shown. I am curious, because they don't go to anything that came in the large lot of items I got last year, and have been a mystery since. I doubt they are useful for anything, but are pretty neat.

Unnoobing my noobness (TECO on RT-11)

by sander.reiche＠gmail.com

Hi all, I'm finally starting to learn using a PDP-11 OS and one thing I'd like to (continue to) do is working on some text. So I've starting to learn (or cope?) with TECO. Found a TECO.SAV on some RT-11 Sigtape to run on RT-11XM. But as the SimH console running the RT-11 is happy typing in lowercase letters, it all goes uppercase inside of TECO. Is there something I need to do to get lowercase working for TECO? .SET TT: LC doesn't seem to work and doesn't seem to be needed as the RT-11 prompt happily accepts (and shows) lowercase. It's just that TECO seems to be flipping the console or input to uppercase. Any ideas or standard tips&tricks/hacks on using TECO on RT-11? With kind regards, Reiche
