TeleVideo's MmmOST

by pat＠vax11.net

I've been adding a few more blog posts, and put up the first one on what (to me) makes TeleVideo actually interesting - their MmmOST client/server operating system. I hope to get more up soon, but I have a (somewhat lengthy) introduction based on what I've been able to learn about MmmOST: https://worldofvax.blogspot.com/2019/04/televideo-systems-part-v-mmmost.html I'm still looking for TS-800A's and TS-806/816's if anyone has some laying around. It'd be informative to get a real MmmOST service processor up and running. Pat

I had one for some time, and it was very reliable and produced high quality output. Also much faster than the Teletype, and faster also than the TermiNet 300 I had at the same time.

Daisywhell typewriter emulating a TTY

by gerardcjat＠free.fr

I would like to emulate a TTY, using a daisywheel typewriter. One immediately think : " Find an IBM Selectric, a Friden flexowriter or a like " But NO, I want something less complex, mechanical wise. That's why I want to investigate on daisywheel typewriters. I am aware of IBM Actionwriter and Triumph/Adler/Royal Gabriele 9009 that can be used as a printer with a dedicated interface BUT that is one way only : Printer only ! >From my investigation, **** so far ***, KEYBOARD does not send ( upload ? ) any signals. ( or a special command code is required ?? ) Any suggestion for "others" daisywhell typewriters that could do OR someone already went this way ? OR any documentation ( even user's manual ) on the dedicated interface : ( IF 600 Computer Interface for Triumph/Adler/Royal Gabriele 9009 ) ( ???name??? for IBM Actionwriter )

I rescued a LaserJet 4+ printer that I have been trying to restore. Initially everything seemed ok and it seemed as if there may be just a bit of an issue with paper pickup which I attributed to old paper in the tray. However, soon I started getting the accordion paper jam which led me to replacing all the rollers including the transfer roller. Now the paper flows freely! However, I am having a new problem with printing. When I print, the first 5-10 pages initially come out blank. The printer does not produce any errors or error codes. The blank pages are warm (not hot though) as expected out of a LJ. After closer inspection it seems that the pages are printed SUPER light and gradually get darker the more I use the printer continuously. Eventually the printer starts printing continuous crisp black pages like new. This is a whole page phenomenon (i.e. not gaps, missing areas, etc.). A picture of the effect can be seen on VFC at: www.vcfed.org/forum/attachment.php?attachmentid=52120&d=1554074105 Sorry for the poor quality picture. Things I have checked/tried: 1. Using a brand new NOS toner (according to HP toner does not go bad as long as it was sealed - which this was) 2. Swapping the new transfer roller for the old one - same problem, I have to print out a bunch of pages until the printer starts acting normally. 3. I have checked the HV and an image is being transferred to the drum on the toner cartridge. 4. A visual inspection of the fuser shows it to be ok. Obviously this is happening printing demo pages so it has nothing to do with computer, OS, SW, drivers, etc. Anybody run into this before? Any ideas/suggestions. My Google fu turned up a bunch of discussions on the laser door not being aligned correctly but that would seem to be a more permanent issue i.e. unless you fixed the door no pages should print ever. Mine gets better on its own after a number of pages are printed. Plus the door and spring are fine - I checked them just in case. I tried posting on FixYourOwnPrinter.com but for whatever reason the site was not accepting the question. Any other forums you guys would recommend? TIA! -Ali

You mean the write rings?? They're fixed at the hub size.... As for write rings, most sites had more than they actually need, many times over.? You really only need as many as you have tape drives... I've always wanted to make an Olympics logo out of write wrings, but never could find all the right colors.

Tape Storage Rack WAS: RE: 1/2" tape storage

by jlw＠jlw.com

> While on the subject of tape storage anyone know if it is still possible to get desktop/table top wire bins to hold tapes in canisters and/or reels? Not that I have that many tapes or anything like that. This would be more for display purposes than anything else. > > Something akin to this: ibm51xx.classiccmp.org/CCTalkPics/taperack.png > > Do they still make things like this or do I have to find it at university junk sale? > > Those are exactly the "dish rack" things I have two of.? Of course, I can't remember where I got them. FWIW, I also have a small rack that holds, uh, 2x4x25 8mm data tapes in their cases.? Said "dish rack" won't fit on top, though. -- Jeff Woolsey {{woolsey,jlw}@jlw,first.last@{gmail,jlw}}.com Nature abhors straight antennas, clean lenses, and empty storage. "Delete! Delete!

Pleas ID this IBM system....

by jnc＠mercury.lcs.mit.edu

> From: Adrian Stoness > someones bid on them eh hopefully not a scraper Well, a scrapper would want to pay as little as possible, so anyone who wanted to actually save the system should be able to get it. There are a couple of bids on it, but the amounts are derisory. I hope Christian's museum can get it! Noel
