Y'all should have spoken up sooner and I might have tried to pick some up for you. Seriously, educate me/us. What's interesting, what would need to be done to care for it through shipping, and what's it worth to you (and I appreciate that the answer to this may not be financial in nature, and it need not be so on my side either!)? More seriously, inexpensive items (say US$1 and under) that don't require a lot of effort on my part can pass easily from my hands to someone else's, and I'm happy to help, especially if it'll help get an interesting story out there to for other folks to enjoy and learn from. As the cost in money, time, and effort goes up, either my interest wanes or I start wanting some return. -Frank McConnell

OT: How to set up Eudora properly :-)

>When I read messages using Eudora 4.3.2 (paid mode) I get to see lots of >headers I can do without. For example a typical message starts: You can try the hack at the following web site. Its supposed to fix this problem with Eudora v3. But the problem appears to be the same issue you are seeing (emails from the Mailman list server show extra headers in the email body). <http://lists.contesting.com/_rfi/2001-December/001115.html> -chris <http://www.mythtech.net>

Wayne, Right on count (2), and it IS like selling one of your blue metallic children that you've kept in a closet for 20 years so you can feed your real family.

New To List and PDP8 Question

by bkotaska＠earthlink.net

Hello, I am new to this group but have been reading the posts occasionally before finally joining. The site comes up alot when searching for info on old machines. I am interested in any type of old computer especially the single board trainer types from the early days of the microprocessors. I have built my own trainer based on the Intel 4004/4040 and have started to put a web site together with pics and info. It is in the early stages though - http://home.earthlink.net/~bkotaska/mcs4_micro.htm . I have also started to build a PDP8 clone from the Harris/Intersil uPs. Still need to gen up a front panel for this one. A computer is just not a computer without some kind of built-in feedback mechanism. (I guess it just makes you feel like you are in control of the machine instead of the other way around.) Building the PDP8 has really piqued my interest in the real thing. I've collected bits and pieces for awhile now and have finally obtained a 4K core stack - although it is not in great shape (any help in locating a better one would be greatly appreciated). Anyway my question to you PDP8 folks out there is this - I have the following pieces: front panel, M8300, M8310, M8320, M8330, M837, M8650, G104, G227. I also have a 20 slot omnibus backplane from a PDP8a. My guess is that I should be able to see some action on the front panel with just the first four modules present (i.e. no memory). Am I correct? I don't care at first if I can't read or write to memory. I just want to check out some of the control functions with as little hardware as possible. By the way, my front panel has mostly light blue and dark blue switch handles. Anyone seen this before? Thanks all, Bill

Free DecServer 200 & 300's for local pickup in NH or Cambridge, MA

by lion＠apocalypse.org

Howdy all, I have 4 DecServer 200/MC and 28 (yes twenty-eight) DecServer 300 to give to anyone who is willing to pick them up in the upper valley region (Plainfield, NH to be exact, close to Darthmouth U/Hanover, NH) *OR* close to Harvard Square in Cambridge, MA. The units are in Plainfield right now.. I'll be in Cambridge from March 19th through around the 26th. I'm not willing to ship these to due to the quantity involved. Hope someone can give the DecServers a home.. -- Michael lion(a)apocalypse.org

Free Scanning Electron Microscope

by j.r.engdahl＠adelphia.net

Free scanning electron microscope to whoever will come haul it away. It was left by the previous occupant of my lab, and it's blocking the hallway. I want it out of there. There are four main pieces, plus some parts and manuals in boxes. I don't know much about this, but I will describe it's appearance: - microscope unit - desk high box with precision stainless steel tower, shoulder high - ISI Robinson detector mounted on side - Perkin Elmer gizmo mounted up high - other probes and sample holders sticking out at odd angles - very rocket science - no other name plates visible without moving a lot of stuff - viewing station and analog controls console - name plate: ISI WB-6 - built-in CRT - lots of knobs and buttons - very mission control - Tracor Northern computer - floor standing console a little larger than an ASR-33 - two 5" floppies - card cage inside - Intel 8080 microprocessor - keyboard - no hard drive, don't think it ever had one - separate RGB CRT - a 2' box with lots of wires and tubes coming out of it - a 3~4 gallon tank that looks like it bolts on the side of the tower - a small rack with instrumentation modules in it The date plate on the back of the viewing console says 1985. It was used by our semiconductor quality control department to look at the insides of integrated circuits. Rumor has it that there is a vacuum leak in this somewhere, it probably needs a new gasket. It is already uninstalled and ready to roll away. I found a web page with a picture of a similar unit. Our machine has an very similar viewing console, but we have more stuff mounted on the microscope itself. http://www.optics.arizona.edu/Milster/Labdescriptions/Misc.htm ***NOTE*** This thing has a radiation sign on it (X-rays). Transportation and use is regulated by the Ohio Dept. of Health, Division of Radiology. I understand you need to get a permit to move or operate it. If you are really interested in this, you need to know how to get the required permits. If you are interested I can take some pictures and send them. -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 1 Allen-Bradley Drive Advanced Technology Mayfield Heights, OH 44124 http://users.safeaccess.com/engdahl j.r.engdahl(a)adelphia.net

Collecting siilicn wafers

by davol＠globalnet.co.uk

I noted some time back that chip collectors are not highly regarded on this site - on the grounds that they are prepard to 'mine' perfectly functioning boards in pursuit of their interest. My interest is in collecting whole, undiced silicon wafers. These are much more accessible for research and the interest does not conflict with those of other people. Are there other interested people out there? If this site is not the best for this sort of discussion can you recommend a better one? Dave

IDing IBM Floppy Drive Parts

by rcini＠optonline.net

Hello, all: I got a couple of IBM-labeled Tandon drives and a MPI/Control Data drive. The Tandon drive is a standard TM100-2A and the CD drive has the following ID#s -- Part 77711801, IBM Part# 1502060. I'm trying to recycle these in my N* (double density setup). The jumper area is unlabeled on these drives, as is the terminator spot. On the Tandon drive, I found a TRW IC near the floppy connector...it has a designation "516-3-151G"...this seems to be the terminator. Can anyone confirm the placement of the terminator and the jumper block pinout for both drives? Any help appreciated.
