Forgot to post here...16Kx1 DRAM NOS at Goldmine

by joerg.sigle＠jsigle.com

Hi Chuck, I just reviewed the datasheets. The pinout appears *mostly* compatible - appart from the fact that the 4116 pin 8 wants +12V, and the 4517 only +5V. The other power supply pins have changed to N.C., so it could be done with a small board change or a small wire by each IC. I was just considering that because I have a machine with 64 x 4116 (and maybe some more in two or three other boards, don't want to look now...), and I would be interested in reducing power dissipation. It may go to 170 mW per chip, ... but while MOSTEK say their 4116 needs up to 1 W max, I just see the TMS4116-20 more probably has 462 mW. So it would save me... 19 W at best. Or less, because the unused power rails cannot simple be turned off - or more, because the PSU is a rather large, old, linear type. Now well - I don't have time; the originals are soldered in, so don't want to ruin the boards anyway. Nor change their original state more than needed for actual repairs. I've already replaced one defective IC of these, so I could at least test compatibility... Has anybody ever replaced memory ICs to save power? Btw., I *might* have to stick with 1 bit RAM in this machine because it might mask individual bits in hardware, IIRC.

DEC R82-HDA for sale

by sales＠elecplus.com

I have one very large old hard drive here, made by DEC. The front face plate is missing. The drive inside says R82-HDA. PN 70-21170-01 The complete unit is an RA82, I believe. Looks like the one in this video http://www.youtube.com/watch?v=lfskSzKBnWA Except for the face plate, it appears complete. This unit is on rails, and came out of an old server years ago. It will have to ship on a pallet. Make offers?

More eBay users selling my stolen property and affidavit exhibits uploaded

From a UK perspective: Without going into details, we are currently in legal battles getting money back off someone, and whilst, so far, we've done everything ourselves (successfully, if slowly) the defendant has been representing himself too. The judges have for the most part been sympathetic and have taken our lack of experience into account. The moment however that he does find himself a solicitor willing to take on his case (he had one drop out already once we explained matters to them), then we'll have to do the same. I've dealt with the professionals in the past, and they are mostly akin to playground bullies, and delight at stomping on the amateurs. Don't let yourself get into that situation. Rob

Vintage Computer Festival Archvies STOLEN by Tri-Valley Recycling in Stockton - now selling on eBay as seller "tvrsales"

by sellam＠vintagetech.com

eBay seller id "tvrsales" is currently selling property STOLEN from the Vintage Computer Festival. If you are planning on buying anything of a vintage computer nature from eBay seller "tvrsales" in Stockton, California, please know that you are most likely BIDDING ON STOLEN PROPERTY. The VCF Archives were STOLEN by Tri-Valley Recycling (eBay ID "tvrsales") in cahoots with the landlords of the building where it was sold. The sordid tale can be read about through lawsuit material already on my website for download: http://vintagetech.com/download/lawsuit/ I encourage everyone to read through the letters and especially the affidavit to see the absolute criminality of these vultures. I am continuing to upload more material as I have time, but the basic story is there. The court system was absolutely useless, as were the police and sheriff. I am having to sue for conversion, fraud, racketeering, unjust enrichment, and probably other charges as I continue my research. I am here to tell you right now: Anyone on the receiving end of my stolen property is going to be entangled in this mess one way or another. Therefore, my suggestion to you is that YOU SHOULD NOT BID ON OR BUY ANYTHING FROM TRI-VALLEY RECYCLING IN STOCKTON, CALIFORNIA. If you do end up with my stuff, you will become a part of the lawsuit in some way. So if you don't want to have legal issues to deal with, stay away from anything they are selling. I think I have made myself redundantly clear here. The full story will come out in time. Right now I'm re-grouping for my next legal attack. Yes, I could use assistance, especially if you have a law background and can do research for me. Sure, I could use money, so send some if you got it. I don't need attorneys. Attorneys are useless in the capacity that I am acting. I'm doing this the proper way: myself. My entire career as a computer historian has been destroyed by these hyenas. Now I have to sit here and watch as they auction off 25 years of my life's work piece by piece. Don't be caught in the frenzy when the lion shows up. -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.
