Dear Richard, I have an HP 4952A that I am trying to coax back into life. It would be very useful to have the software that you have mentioned as alas the disks have disappeared. A point that may interest you is a note in the operating manual (at least it was still there), section 12-21 concerning the copying of disks. {Note: Some software applications are not reproducible. The will appear to be copied, but will be non-executeable. When you try to load this type of application, the HP4952A will display the error message 'Application Denied'.} This seems to explain the problem that you encountered. Anyway I would like to have a go at persuading the the analyser to accept these files. It may be possible to open up these files and "hand input" them into the analyser and then save them to disk for later use. As the saying goes: "Nothing ventured, nothing gained". Regards, Rupert.

GE Terminet terminal

by jpl15＠panix.com

What is being described is almost surely a Terminet - an ASCII teleprinter using a continuous rotating band with upright 'fingers' containing the individual characters - these passed in front of 72 hammers, and behind them were the ribbon and paper respectively. There were three complete sets of character fingers, thus cutting the 'latency' of the band in thirds. When the right character arrived at the correct position on the page, the opposing hammer fired and imprinted it. The fingers were easily removable allowing for alternate fonts and character sets. The two I had were fitted with the dual cassette units (used instead of paper tape, (but employing very much the same 'algosithm'), and I used them in the very early 80s with a 300 Baud Novation JCat modem, to access Compuserve and a couple of other primitive on-line services, as well as BBSes. The unit is well worth saving - you don't say where you are, but they are rare now and I'm sure someone will be very happy to make it go away for you... Cheers John

DEC VT102 terminal question?

by jwest＠classiccmp.org

I have a DEC VT102 terminal that I got some time ago from a listmember. On the right of the keyboard where the numeric keypad is, the keys don't match the color of the other keys on the keyboard. The upper left key in the keypad is gold, and the other keys on the keypad are different colors - red, blue, white - and have editing words on them, I think words like "left, copy, print", something like that. My question is - is it likely that someone scavenged keys from another non-vt100 keyboard to replace missing keys, or was this some option used with some word processing software? If the later, I'm happy I have something unusual. If the former, I am going to yank those keycaps off and scavenge the "correct" keys from one of the other VT100's I'm going to junk. Anyone know the answer? Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

DZ11 pinout?

This is for a DZ11-A/B/E, M7819. The 20mA versions (DZ11-C/D/F, M7814) are different. The information isn't in either the User Manual or the Technical Manual, so I resorted to reading circuit diagrams from the module assembly microfiche. It's not very clear in parts, but the pinout is: Chan. TxD RxD SG DTR DCD RI 0 19 21 22 1 2 20 1 23 25 26 3 4 24 2 27 29 30 5 6 28 3 31 33 34 7 8 32 4 35 37 38 9 10 36 5 39 41 42 11 12 40 6 43 45 46 13 14 44 7 47 49 50 15 16 48 Pins 17 and 18 are also ground. On the DB25 end, TxD is pin 2, RxD is pin 3, SG is pin 7, DTR is pin 20, DCD is pin 8, RI is pin 22. -- Pete Peter Turnbull Network Manager University of York

Washington DC classic computing resources/museums?

by jbmcb＠hotmail.com

Yep, you're probably right. I couldn't find my pictures to confirm, and if I remember right it had the odd pinstriping of the PDP-15 series. The "Straight-8" is sweet, looks like it's a sci-fi prop, as if it should be driving the Tardis or something :) >From: Ethan Dicks <dickset(a)amanda.spole.gov> >Reply-To: "General Discussion: On-Topic and Off-Topic >Posts"<cctalk(a)classiccmp.org> >To: "General Discussion: On-Topic and Off-Topic Posts" ><cctalk(a)classiccmp.org> >Subject: Re: Washington DC classic computing resources/museums? >Date: Tue, 1 Jun 2004 22:17:53 +0000 > >If it's the large machine in the corner, off the main path (just past the >Straight-8), that should be a PDP-15.

Needed "data processing magazine" also any of same topic are from 50's 60's 70's such as "Datamation", ACM conference proceedings, Early AFIPS, and others. Also have a requirement for any of the IRE - IEEE publications on early computing. Please advise All eras are fine prefer bound but... loose OK too. address is below.

Atlantic Research Corp. "Interview 40B"

by billdeg＠degnanco.com

Can anyone identify the purpose of an Atlantic Research Corportation (ARC) Interview 40B Data Analyzer? c. 1984. Is this a tester for cable, modem, printer, output or pin outs? Anyone have a manual? It appears to work, in that it powers up and you can get to the menu I have reproducted below. Here is a picture I found on the internet. http://www.torontosurplus.com/air/DATA2997.

selectric consoles

by akb+lists.cctech＠imap1.mirror.to

I think Selectrics are pretty cool; I'd kinda like one I could use as a printer, and if it could be a full serial tty that would be even cooler. So far, I've found that IBM made the 1050 and the 2741 selectric-based console terminals, both of which were large, heavy, and not very reliable. Did IBM ever do any better, like say a serial module for a selectric III? I know some of the Wheelwriter typewriters had serial ports, but the golf ball type elements are just too much cooler. I found some web pages that talk about Trendata ttys based on selectrics, but very little hard info; anyone here know anything about them? I also remember the ByteWriter and similar contraptions that strapped a bunch of solenoids on top of a typewriter keyboard, but while entertainingly kludgy, that lacks a certain degree of elegance. --akb

Places that supply model engineers would be able to do that. I use ones in the UK so I can't suggest specifics, but a Google search should find a few. -- Pete Peter Turnbull Network Manager University of York
