Actually, in the States a "phone plug" or "phone jack" is 1/4" -- the kind used in ancient telephone switchboards, hence the name. To make it more interesting we also have "phono" (aka RCA) jacks and plugs, used for connecting phonographs and their amplifiers. Do these connectors have different names on your side? Glen 0/0

IBM System/38 Info Needed

by mrdos＠swbell.net

I was just wondering if anyone knew anything about the IBM System/38, or had any software or books for it. Do y'all think it is collectable? Thanks, Owen

Unknown DEC stuff and a few unknown ICs

by xds_sigma7＠hotmail.com

Hi, I can't figure out what the heck these two Intersil chips are; one is a 6003 and the other is an 5110. Also, I have these qbus boards from Sky Computer that I have no clue what they are; they're all quad height (assuming that means they have four connectors). They are Skywar-Q-A-03, Skywar-Q-B-03, and Skydpmem-Q-02. Will J ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

I'm leaning towards RF11, as the data width on the panel appears to be 16 bits. (Maybe the same panel was used on both the RF11 and RF08... I dunno.) The RF11 runs the RS11 fixed-head disk, 128 cylinders * 8 blocks per cylinder for 1024 512-byte blocks in total. The capacity in 12-bit-word mode is likely different. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

some DEC finds

by lemay＠cs.umn.edu

I just picked up a DEC PDP-8/L cpu unit, someone had already taken it out of the rack for me. How can i determine if I have a complete cpu? most of the cards are present, and there are 3 cables coming from the unit, each with a centronics connector at the end. There is a rack of mystery DEC equipment, lots of green G series boards, etc. At the top of the rack is an array of lights, and I found a plastic panel that obviously was supposed to be over those lights. I've taken a photo of the panel, hopefully someone can identify it for me. Other stuff in the rack is on wirewrap backplanes, and the flip chips are plugged in from the bottom, i'm guessing this stuff goes with the 8/L cpu. http://www-users.itlabs.umn.edu/~lemay/panel.jpg We also grabbed the top half of a teletype 33 ASR for parts, and plan to return with a truck tomorrow for a complete Teletype 33 ASR. There is still a complete PDP 11/20 rack system, with dectape, decpack, and possibly other stuff in addition to the cpu unit itself. My friend will try to rescue this, if we can borrow a pickup truck. Other stuff out on the loading dock includes a DecScope, 2 DecWriter II, 1 DecWriter III, 1 Decprinter. I've contacted the person who is discarding this stuff, to see if anything else is available, such as manuals or dectape. By the way, i'm not planning to take the printers I just mentioned, I just dont have much storage space. Since this is the first 8/L system I've seen in person, any help in determining if i have a complete system would be appreciated. Also, what are those 3 centronix connectors for (connections to expansion units in that other rack maybe?) and how can I connect a terminal or something to make this thing a bit more usable? -Lawrence LeMay lemay(a)cs.umn.edu

Archives are now online

by af-list＠wfi-inc.com

Hi all, I spent my lunch break finishing the configuration for the mailing list archives. Due to underwhelming popular vote, the email addresses of posters have been xxx'd out; if you really want your email address to appear with your messages in the archive, you'll have to append it to your sig. The URL to access the archives, at this moment, is: http://www.retrobytes.org/classiccmp/ For the moment, it is a pretty plain setup. The archive is split into separate pages of 75 messages each (my only complaint with other archives: it takes *way* too long to load a 500k archive list every time!) and can be viewed as sorted by date (default page), thread, and author. Soon enough, I hope to add a search engine and better browsing manager...though I don't know when I'll get the time. If anone on the list is a Glimpse expert and has a little time, I'd be happy to set you up a login account... :) Enjoy! Aaron

Mailing list archives? Questions...

by af-list＠wfi-inc.com

Hi all, I know that Kevan posted that he's working on getting his archives back up, but a question in the meantime... I've been thinking of making a new archive of the list available at retrobytes.org (starting with this month); any comments/concerns/advice? Do I have to get anyone's explicit permission to do this? Lastly, assuming I go through with this, would people prefer that I set Mhonarc to obfuscate everyone's email addresses? The benefit, of course, is that a spammer's address crawler couldn't pick up everyone's addresses >from the page like they do on newsgroups; the drawback is that people wouldn't be able to directly contact the authors. If the general feeling is that you'd rather the addresses be hidden, perhaps I could create two archives...one private for classiccmp list members to search the archives *with* addresses, and one public with the obfuscated addresses. As usual, any imput at all would be appreciated. Cheers, Aaron

One of only 3 "enigma machine" stolen; A piece of ENIAC was u p for auction.

by CordaAJ＠nswc.navy.mil

Interestingly enough, I ran across an Enigma machine at a hamfest in MD. last year. The gentleman had it on a table amidst a bunch of WWII radio gear. I did a doubletake when I saw it (I only recognized it because I've seen the one in the Smithsonian). It was missing the encoder wheels, and I seem to remember that he wanted somewhere around $7K for it. I'm pretty certain he didn't sell it, and I haven't seen it at any hamfests since, but perhaps he'll have it there again this year. -al- > -----Original Message----- > From: Hans Franke [mailto:Hans.Franke@mch20.sbs.de] > Sent: Monday, April 03, 2000 4:12 PM > To: classiccmp(a)classiccmp.org > Subject: Re: One of only 3 "enigma machine" stolen; A piece > of ENIAC was > up for auction. > > > > > >I see it as another sign of how serious our hobby is > becoming.
