I have an entire case of adapters, made by Energy Transformation Systems, Inc. I called their tech support this morning, and was told that these were made for Token Ring connections, using IBM Type 1 or Type A cables? There are 2 different PN: EB-TRT-I has impedance matching, uses pins 3,6 and 5,4 EA-DATA-U does not have impedance matching, also uses pins 3,6 and 5,4 These have female RJ45 on one end. Apparently they are used to connect to a MAU? They look like these http://www.cuc.eu/en/li/conrj/rjembase/879700.html But use pins 3,6 and 5,4. Anybody trying to resurrect any old TR stuff? I confess, these are way beyond what I have any knowledge of!

AT&T 6300 mono monitor

by gerardcjat＠free.fr

The AT&T 6300 can be operated with a monochrome monitor like a 5151 or a Hercules monitor. You have to install an MDA-card on the system bus and connect it to the mono monitor. Maybe that is the way the 5151 of Chris Tofu works with the 6300. If you want

If you are prepared to pay for shipping from Europe, you could have a look on ebay.de (Germany) for example, or one of the other European national ebay sites. I got mine from Tradera which is owned by ebay (www.tradera.com), they turn up there every now and then, mostly 520s and 1040s. Shipping would probably be quite expensive though. Jonas

IBM Displaywriter software?

by colineby＠isallthat.com

Al, I'm away for the holidays, but could have a rummage at TNMoC when I return. My next day at Bletchley won't be until the 12th. But do nag me if you don't hear back. I know we have at least one system, but its in storage. It would likely have arrived with some media. The media would have been directed off into the archive section. That makes me think it likely we'll have something. --Colin Al Kossow <aek at bitsavers.org> wrote: >Is there an image archive of software for the Displaywriter somewhere? >Someone donated one to the Computer History Museum recently, and I went through our archives and have >only come up with a bunch of versions of the CE disk and a single TEXT PACK 1 diskette. > >I did image what we have, and put it up under http://bitsavers.org/bits/IBM/Displaywriter > >One thing I discovered was you HAVE to degauss the floppy before cloning the CE diskette.
