This happened to a ROM in my oldest PET when I was trying to reseat it (poor contacts in sockets - I eventually replaced them with decent sockets). I stuck a thin piece of metal - a staple, as I recall - into the socket where the pin was supposed to go, and soldered it to the stub of the pin. Worked a treat! Philip.

Power supply pinout for HP Windows Client???

by af-list＠wfi-inc.com

I got one of these today, a 425sx, sans powersupply. The sticker on the bootom is scratched and I can't read the power requirements, though it looks like it might read 20V....something. It's got a 4-pin jack on the side for power, if that helps... Aaron

tektronix 4006 terminal

by danburrows＠mindspring.com

Desktop 4800 baud max. Otherwise the same spec's as a 4010 IIRC. I might still have a manual somewhere. A company I used to work for used them on their low end mass spec's.

My Biggest GRIPE, period...

by philclayton＠mindspring.com

>> I respectfully request that the parties discussing Ebay in gory detail >> please spare us all and take it to E-mail. >> >> Sheesh... > >I second that motion! > >Steve Robertson - <steverob(a)hotoffice.com> For what its worth I think most discussions on the forum will naturally end when everyone is tired of the subject, and not when one or two individuals say it should stop. I think "My Biggest GRIPE" was a good topic since most of us trade on eBay, I think it was an important discussion. I know the subject has been on this forum many times before, but there are new users here and I am sure they learned many things from the discussion on the In's and Out's of eBay trading.. Personally I don't read discussions on PDP-8's or Vax's, Have never even seen one, and likely never will.. My interest is mainly Pre-DOS Micro computers. To be honest about 50% of all that's discussed here is not in my main interest, but I have no right to tell anyone here not to talk about the subject.. So if you need to turn on your "eBay" filter, I will just turn on my PDP-8 filter, mine is called "Press the delete key" it only takes 1/2 a second.. Phil..

DEC

by CLASSICCMP＠trailing-edge.com

>4) If it has non-DEC stuff in it (like the memory is all 3rd party non-DEC >MOS RAM) then that would negatively affect the price. Some of the most valuable/useful stuff you might find in a PDP-(anything) can be the non-DEC stuff. For example, I wouldn't complain at all if I opened up an 8/E and found the OMTI Omnibus SCSI host adapter inside! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

DEC

by Hans.Franke＠mch20.sbs.de

Well, I don't like to push anyone, but I still need some hints what a working PDP 8f is worth, or until which amount it isn't a compleete rip off. AFAIK at least two disk, fro 8" floppy and one tape drive is included (no idea about the types, since I'm no DEC-o-maniac at all). The machine is still in use, but may be replaced at any moment (replacement PC already set up).

OSI C4P-MF board (was Re: Tandon TM 100 5 1/4" drives)

by ethan_dicks＠yahoo.com

--- Doug Coward <mranalog(a)home.com> wrote: > The C4P-MF is coming along nicely. Thanks for mentioning this. One of the things I found in my weekend's DEC excavation is my C4P-MF motherboard. Someone on this list, perhaps you, Doug, expressed an interest in it. I know I have the service docs in a different box, but for now, I've found the board itself. The 40-pin chips have gone wandering (probably in my parts drawers); I'd like to know what sockets are supposed to contain what parts (probably a 6502A and a couple of 6821's) so I can locate them and put them back. I will probably never run across a real Challenger-4 for this to go into, and I have no interest at this point in fabricating the necessary accessories to make this useful. I anyone wants this board, contact me offline. I'm interested in trades over cash - 1970's micros of most kinds are interesting to me. Enjoy, -ethan ===== Infinet has been sold.

Preventing cartridge tape stickiness

by rdd＠smarty.smart.net

Can anyone provide any information about the best way to preserve cartridge tapes, such as DC300 tapes, so that parts of the tape don't stick together? Using new 3M DC300 tape several years ago, onto which I'd copied the source code to the S.6 version of the Accent operating system, the tape stuck together about two years later and was destroyed when I tried to read it. Not sure how to try to preserve the rest of the data, written with the Stut (the streaming tape utilitu software) software, that's still on the tape - any ideas? -- R. D.
