[PDP8-Lovers] Re: how to clean a PDP8/A, dishwasher?

by Robert_Feldman＠jdedwards.com

For laughs, take a look at http://www.help-net.com/computer%20buddies/pc911/clean_your_hard_drive.htm -----Original Message----- From: Matthew Sell [mailto:msell@ontimesupport.com] Sent: Monday, December 17, 2001 11:16 AM To: classiccmp(a)classiccmp.org Subject: Re: [PDP8-Lovers] Re: how to clean a PDP8/A, dishwasher? <snip> Wrong. One manufacturer I worked for used a commercial Hobart dishwasher that was modified by an electronics distributer to include racks specifically made to handle printed circuit boards. This "boardwasher" was literally a dishwasher. Not a unique setup, either. You say there is a huge difference. What are the differences? Every boardwashing setup at every manufacturer I've consulted or been an employee of used a system that washes boards using higher water pressure and temperature than your common household dishwasher. If you are referring to a big difference, then I guess you are right. Your dishwasher is *MUCH* more gentle for the items being cleaned than the typical commercial boardwasher. <snip>

I this has already been mentioned, but also don't put boards in that have any sort of battery fitted or removeable labels you want to keep stuck on.... -- adrian

Hardest to Find Classic Computers (Was: RE: Way OT: Just say no to squirrels & Pascal question)

by csmith＠amdocs.com

> -----Original Message----- > From: no [mailto:oliv555@arrl.net] > digital Alphabook. Not exactly Rare, just hard-to-find Last I checked you could get them refurbished from Tadpole/RDI. Depending on availability, of course, but they get them occasionally. They still cost several thousand dollars, IIRC.

As has been said before, what do you think manufacturers do at the end of a production line? Yes, a certain amount of care is required, and certain things can't tolerate being soaked or being too hot or given too much mechanical agitation (stress). But how would you deal with a piece of equipment that was smoke damaged or had been left in the rain or had fallen in a river or had been infested with vermin or had a can of Coke spilled in it? I've had to deal with all of those and more over the last two decades, and washing is the only way. I don't advocate unneccessary cleaning, but sometimes it's required. > > It may be alright to (gently!) vaccuum away dust and deteriorated foam > > rubber, although a feather duster may be more appropriate.

Be careful about that. Allison's warning about ESD is quite real. Don't even think about a feather duster; at least, not if it's a synthetic one. -- Pete Peter Turnbull Network Manager University of York

Databooks

by DAW＠yalepress3.unipress.yale.edu

Pete - I'm forwarding this to ClassicCmp.org mail list for you. Someone there might want them... From: CaptnZilog(a)aol.com [mailto:CaptnZilog@aol.com] Sent: Friday, December 14, 2001 3:52 PM To: port-i386(a)netbsd.org Subject: OT: Databooks Way off topic here, but I figure that this list is probably looked at by most of the people out there. I have two xerox-paper boxes of duplicate Electronics Databooks I've weeded out of my three 7' high bookcases of databooks. Anybody out there in the vicinity of CT (probably not worth shipping them, its a lot of weight) interested in any databooks (to add to your collection?)? I can provide a list if you want. Some TI DSP databooks, and miscellaneous other stuff...

How did they string core?

As the cores got small and smaller the operation became harder and harder. We used a large screen like device with slots in it. The cores were dropped onto the screen which was shaken so that the cores would fall into the proper holes. Then a button was pushed and the N/S and then the E/W wires pulled through the centers of the cores. The last part of the operation was the diagonal (bias) wires which were threaded though by hand. Very few individuals were capable of this last part of the operation. Almost all of the operators were women. Men just couldn't do the fine point work. --------------------------------------------------------------------------------------------- gene(a)ehrich.com gehrich(a)tampabay.rr.com P.O.
