Acquired an Intecolor 8001, but haven't yet turned it on. Is there anything *specific* about this system to watch out for? I don't have a service manual or schematics. I know that on the CompuColor II, a close relative, the CRT controller IC is sensitive to over voltage. Thanks- Steve.

IBM 3278-2 terminal, for those that asked

by sales＠elecplus.com

The unit powers on, lights one and 2 come on, and that is it. My IBM buddies tell me it is because I don't have the mainframe to test it on. No evidence of screen burn.

Bogus VT420 on Ebay

by mloewen＠cpumagic.scol.pa.us

I ran across this on Ebay: 160925314748 The pictures are from my web site, and the description AND serial number listed are lifted right off my page: http://sturgeon.css.psu.edu/~mloewen/Oldtech/Terminals/VT420.html Even more amazing, someone apparently already bought one and gave positive feedback! Needless to say, my terminal is not for sale. I've filed a fraudulent listing complaint. Mike Loewen mloewen at cpumagic.scol.pa.us Old Technology http://sturgeon.css.psu.edu/~mloewen/Oldtech/

A curious item has come up on ebay: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=251189751428&ssPageName =ADME:B:SS:GB:1123 Was there some kind of PDP11 addon to a 2000? Or is that just a PDP11 label stuck to a VAXstation 2000? Regards Rob

Upgrading Memory on a VAXstation 3100 Model 38

by robert.jarratt＠ntlworld.com

I recently acquired a bunch of MS42 memory options boards (several 4MB, one 8MB and one 12MB). The 12MB one could be used to take my machine from 20MB to the full complement of 32MB. The trouble is that the mounting posts used when you only have one memory option board foul the second memory option board, the manual tells me to break the old posts off, but I don't want to do any physical damage to the machine (would prefer to stick to 20MB if I have to). Is it possible to get the mounting posts out without breaking them? Or, does anyone have any spare ones? Ideally I also need the E clips to keep the two memory options boards properly spaced, I suspect I can survive without them, but if anyone has any of these going spare I'd be interested in some.

manx 2.0.3 is online

by legalize＠xmission.com

Hi All, Over the past year I've been working on manx now and then. Mostly I wanted to add a convenient way for me to incorporate scanned content I've contributed to bitsavers into manx. That system has been in testing for a little while now and I believe I've gotten things working to the point where they are usable by myself and a few select users to add new content to manx. For end-users you'll notice a few little bugs fixed and some new features. There is now an RSS feed of documents added to manx so that you can track new additions to manx. <http://manx.classiccmp.org/rss.php> is an RSS feed of the 200 most recently added documents. If you see any problems with manx, please file a bug report at <http://manx.codeplex.com>. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
