That was well before 1970. And in Sweden. Jonas

Historical Computer Society

by david＠classiccomputing.com

After a poor turnout at my place of work, I canceled trying to hold meetings there. Instead, I created a discussion group for the Historical Computer Society. There are a few of us there now, and we are building a grassroots organization that way. This is a group to become a lot like MARCH (http://www.marchclub.org/) for the greater Atlanta / southeast US region. A few of us had our first meeting in a restaurant yesterday, so I think that is a good start. More information is here - http://www.classiccomputing.com/CC/Meetings.html Anyone in this area, please consider becoming a part.

Big PDP-11 pile on Ebay

by wdonzelli＠gmail.com

There is currently a pretty big PDP-11/44 collection on Ebay (just search for PDP-11/44). It is located in Milwaukee. Will anyone here be bidding on the pile? If so, and you win, I would be interested in one or both of the RK07 drives, but nothing else. Reply off list...we could come to terms... -- Will

Hi again, Christian > >PS: Using the shorter URL >http://lh4.ggpht.com/_lkddKjPsPFU/TUswHtRykbI/AAAAAAAAB6k/1ne8IFziAUU >gives you the full sized picture. > On further investigation, I find that if I open the full URL first, and then shorten it down to the above, I then get the full sized picture with no problems. However, if I go straight to the short URL above, it fails with the "Not found" error I mentioned in my previous mail. Google must be doing something really strange. Regards, Peter.

Tektronix 4010/4014 terminal printer project

by legalize＠xmission.com

OK, I've been studying the circuit diagrams and service manuals for the Tektronix 4014 printer interface: <http://bitsavers.org/pdf/tektronix/401x/070-2303-00_4014_4015_Service_Mar79…> <http://bitsavers.org/pdf/tektronix/463x/070-1831-02_4631_Service_Nov79.pdf> I'm starting a project to create a modern printer interface for the terminal. This involves creating the optional target signal amplifier board for the 4010/4014 and creating a microcontroller based board that will drive the terminal like a 4631 printer and scan out the image from the storage tube for digitizing as a digital image. The amplifier board is what distinguishes a 4010/4014 from a 4010/4014-1 and provides the signals for the printer. The original 4631 printer is a completely analog device that scans out the storage tube and transfers the electrical signal to a dry silver paper for printing. This design will treat the analog signal supplied to the printer as a signal for digitizing into a raster image. I plan on housing mine inside a 4632 video hardcopy shell with a modern printer inside driven by the controller. Who knows, this project might make those 4631/4632 printers useful again, considering that noone is going to be getting a new supply of dry silver paper anytime soon. I'm looking for other people that have hardware design experience to join me on this project. All resulting EDA files will be made available under a suitable open source style license. Please reply to me off-list if you are interested in collaborating with me on this project. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
