Early CD-ROMs was: NASA computers circa 1969

by barythrin＠gmail.com

What country/nationality are those names? I'm jealous. They sound straight out of a Tolkien novel. -----Original Message----- From: "Bill Sudbrink" <wh.sudbrink at verizon.net> Sender: cctalk-bounces at classiccmp.orgDate: Fri, 04 Jan 2013 16:49:56 To: 'General Discussion: On-Topic and Off-Topic Posts'<cctalk at classiccmp.org> Reply-To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: RE: Early CD-ROMs was: NASA computers circa 1969 Dave McGuire wrote: > You didn't work for a flaming asshole of epic proportions > who went by the name of "Murf", did you? No, not that I remember. Are you talking about someone at Meridian? I didn't work there, I worked for AIRS (Automated Information Retrieval Systems) back then. The guy I worked for was named Eldon. I collaborated with (over the phone) a a guy named Wink at Meridian. What was his last name? Like the chipmunk guy I think... Seville? We were one of Meridian's first customers on the East Coast. Wink wrote their custom drivers. Before mscdex, before Yellow Book, back in the dark days. Bill S.

8 bit virii

by tshoppa＠wmata.com

geneb writes: > As far as I know, there was never a known instance of a virus on an 8 bit machine. "Elk Cloner" for the Apple II, according to Rich Skrenta went wild in 1982. Was written up very nicely in a Scientific American article in March 1985 (good enough that I wrote a "me too" virus based on the article.) Very similar to what a IBM-PC guy would call "a boot sector virus" (although really there's a little more than that in either the Apple II or PC-clone cases.) It would be interesting if any of the Apple II disk image archives, have Elk Cloner or lookalikes in them. I once thought about automating such a search as an addition over the effort to index the Apple II disk images floating around on the net. Haven't thought of that in, oh, nearly 20 years now!!! Tim.

3.5 alignment? (~~opps, not 3.25!)

by pinball＠telus.net

Looking to test/service/align a number (10 or so) of double-sided double-density 3.5 floppy drives and hoping there is someone here in Canada who has the alignment discs that I could borrow/buy. These are for setting up some of my older computerized microprocessor test gear (Fluke mostly)... Suggestions on aligning are also greatly appreciated! Thanks!

NASA computers circa 1969

by dgriffi＠cs.csubak.edu

I just stumbled across a sort of show-and-tell of computers used by NASA in the 1960s. See http://www.youtube.com/watch?v=nrwpXEiTDVk -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing?

Atlantic research 4500 manuals

by hp-fix＠xs4all.nl

I'm looking for the manuals or copies of my Atlantic Research 4500 protocol analyzer. If somebody has a copy for me I would be very happy. -Rik PS. I got a spare unit if anyone wants it, it is a but busted and the tape drive is missing but it seems to work.

rtVAX 300.

by holm＠freibergnet.de

Next time I'll get this: http://www.tiffe.de/images/11122012114.jpg Is anything known about this board here (Manufacturer, Adresses, Switch settings and so on)? Looks to me like an VAX upgrade to an PC with onboard SCSI, Ethernet and Serial Ports... I have 2 2nd rtVAX board here from a friend, this is a VME CPU with SCSI on board. I should look if I could get it to boot.. Any hints welcome, Holm -- Technik Service u.

PDP-8 Paper Tape Reader Emulator

by michael.99.thompson＠gmail.com

With lots of help from members of this forum and other friends I made a high-speed paper tape reader emulator from a wire-wrapped interface board and an Emcraft SmartFusion FPGA evaluation board. The interface board plugs onto the Posibus interface slots in a PDP-8/L. I loaded Focal from a BIN paper tape image into a PDP-8/L in about 2 seconds. That equates to about 3000 characters per second. I put some details about the project here: https://sites.google.com/a/ricomputermuseum.org/home/Home/equipment/pdp-8-l… I will make an expanded version of the interface board and change to the Emcraft SOM FPGA board. That will give me enough I/O pins to emulate just about any peripheral that you can connect to the Posibus. It would be possible to make an interface board for the Negibus so that the peripheral emulator could be used on earlier PDP-8 systems. -- Michael Thompson
