PDP-11/44 Sun 3/160 MicroVAX II and More in MA on ebay

by mc68010＠gmail.com

This is a cool lot for someone a lot closer than I am. It's in Gloucester, MA. It is only a 3 day auction and it could end up being a rescue by the sound of it. Hopefully someone can save it from landfill. http://www.ebay.com/itm/231018428749

Circuit Cellar site...

by LYNCHAJ＠YAHOO.COM

Hi! Thanks to everyone for all the great work you've been doing in my partial absence. Still trying to sort things out and making some progress but slow and very intermittent. Would someone please take another whack at the Wikipedia Gods (aka editors) to reinstate the N8VEM article based on the great work that Oscar has done? He has singled-handedly done a huge amount of work getting the Circuit Cellar article published. That may be enough to spur them to reinstate. Always open for discussion and new ideas. Thanks and have a nice day!

Sorry if I caused any grief by bringing this up. No, not at all - the idea of getting these articles published was exactly to get justification for a Wikipedia article. It's also a nice demonstration about the difference between Old Print Media and the internet age... getting the darn thing in the magazine costs 10 months. Some people develop two generations of a computer + operating system in less time than that :) Regards, Oscar.

Help with a .MACRO in MACRO-11

by jhfinedp3k＠compsys.to

I have a program in MACRO-11 and I have retained just the essential aspects related to my question. That portion of the program is at the bottom. I have unsuccessfully attempted to isolate the first 5 characters of STRING in the MACRO ABC, but I have been unsuccessful. Concatenation is possible along with checking individual characters of the argument, but there does not seem to be support for changing the last character from "T" to "2" as in my example. If that were possible, I could always use "ABC WRKTXT" and check to determine if "WRKTX2" was a defined STRING name at which point the MACRO ABC would automatically use: : Mov #WRKTX2,-(SP) without the necessity of providing the explicit STRING name of WRKTX2 to be used WITHIN the conditional A$. It is essential that the address of the STRING be placed on the stack when the text is in the .PSect TX2. Sometimes, the text must remain in .PSect TXT, so that is why ABC has the additional code to detect the last character of STRING. As I have shown, it is possible to determine if the 6th character of the STRING name is a :"2", but I don't seem to be able to strip off the 6th character of the name from STRING and replace it with a "2". At that point, it would be possible, still within the MACRO ABC, to test to see if the STRING name for which the 6th character has been replaced by a "2" exists and use the second form of ABC. Thank you in advance for any suggestions?

Solvents for removing very old masking tape from front panels?

by derschjo＠gmail.com

My PDP-8/L arrived this afternoon (in one piece and without any damage) and I'll be going over it and cleaning it up over the next few days. Looks like it won't take much more than elbow grease to make most of it look nice again,but there's a big piece of masking tape stuck right above the switches. Age has more or less permanently affixed this to the front panel -- any recommendations as to how to remove this without damaging the front panel? Thanks, Josh

Circuit Cellar site...

by marvin＠west.net

In case anyone is not aware, a lot of the Circuit Cellar magazines are posted online in digitized format at: http://archive.org/details/magazine_rack Also of interest is 73 Magazine back in the late 70's and early 80's as there are a number of good articles on the early computers (Kim1, etc.) The only unfortunate thing is they are scans so you can't cut and paste >from the articles except as images.
