This might be a good one for the KB/FAQ (can't remember how to get in, though- no links on the home page) What should be done to keep older drives, especially sealed Winchester-types, happy? I've been spinning up mine every once and a while, but is there anything else? -Scott Quinn

IRIS 3120 (impostor) in Renton (Seattle area)

by compoobah＠valleyimplants.com

I went down and wound up walking out with the IRIS. It has keyboard, buttons, monitor, cables and appears complete (including Winchester), but is not a 3120, and under intensive interrogation we obtained a signed confession to this and many other unsolved crimes. It's a 2000 of some sort, but in a 3120 case and with a 3000 series keyboard. I'm not sure what the provenance is (some gunk on in, pretty clean and no beasties lurking), or whether the drive is set up fora Turbo 2k/3k system or a 2k (or nothing). ST-506 full-ht. drive but haven't gotten that far inside it yet. It's loaded with bitplanes (8x BP3 boards), but 2 of them do not have the blue interconnect cable attached. Is this correct (are there any members skilled in IRIS lore?)

Restoring (and I do mean 'Restoring!') Plastic

by kyrrin＠bluefeathertech.com

Hi, gang, Got a couple of 3M telecom test sets (965TD's) that need some cosmetic help. No, they're not off-topic. First, they both use an embedded DOS-based computer, and second they're both over ten years old. Anyway... The outer housing is made of (I think) high-density polyethylene, the same stuff that the outer jacket of telephone cables is made from, molded in bright glossy yellow. At least it was bright and glossy when new. As one might imagine would happen with field craft instruments, these have been dinged and marred pretty badly. My question is: What's the best way to restore them? I've tried simple plastic cleaner/polish, and it helped a bit, but the scarring is still there. What I'd like to do, ideally, is take enough of the outer layer off to smooth things down, and then polish it up so that they look new. With that in mind: Anyone know a good way to recondition HDPE? Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

interested in obtaining early workstations

I was trying to be tackful but I guess I'll just go ahead and say what I was thinking. It makes the original poster look lazy/immature/ignorant or possible all three. It's not just his repeated use of the (non)word "stuph" but also his grammer, lack of punctuation and capitalization as well as other distorted spellings. > >Irony abounds. > >The word you meant is "tactful." Unless, of course, you meant lots of horse harnesses. Like Zane said, my spelling is lousy but I at least make an attempt. Joe

Quest for DEC LPS-40 Documentation

They were bought under DEC cost center when I began that project. Still refer to them. There were a few of the DOCs on system as help files and readable docs in bookreader format. I'm sure some made it to CD. Also the LPS20 used the same host system software package with the difference for the load image for the printer. The LPS40, 20 and later 32 used a MOP loaded system image for the printer which was uVAX based. >Since I have never had the privilege to install and set up one >of these printers I would rather have plenty of information.

I've trained the FS trainers and at one time could rip a LPS40 down the bones and reassemble it. Still have part of the IGRP and HeNe laser from the print engine. My MVII is really an ex MV from an LPS40. I spent from 1983 to 1990 as part of that project along with LN01S LA75, LN03 and a few other printing bits. Allison

Looking for a Mac plus keyboard

by CCTalk＠catcorner.org

Picked up the main unit (with a 68030 upgrade, 4 meg ram, external SCSI drive) at a local self-store sale. If anyone has a keyboard for these that they're willing to part with let me know. I am willing to pay for it (just not a lot ;-) Shipping would be to New Jersey, USA. Kelly

Quest for DEC LPS-40 Documentation

by john＠guntersville.net

Does anyone on the list know of online documentation or have the paper versions for the following docs. So far all I have found online was a list of docs on bitsavers and other locations but they didn't show a location for these. Printserver 40 Service Repair Guide EK-LPS40-SV VAX/VMS Installation Guide: Printserver 40 Client AA-HL83A-TE VAX/VMS Installation Guide: Printserver 40 Supporting Host AA-HL90A-TE VAX/VMS Management/Users Guide: Printserver 40 Client AA-FP19A-TE VAX/VMS Management Guide: Printserver 40 Supporting Host AA-FP24A-TE Also the following related documentation would be nice to have but not all that necessary. Postscript Language Tutorial and Cookbook AA-HL86A-TE Postscript Language Reference Manual AA-HL87A-TE Printservet 40 Programmer's Supplement AA-HL84A-TE Postscript Transilators Reference Manual AA-HL85A-TE Thanks in advance John

HP85 sticky keyboard

by tponsford＠theriver.com

I just got around to checking out a pretty clean HP-85 I picked up at auction last month. So far it powers up and runs a simple basic program I typed in. I haven't checked out the cassette, although it doesn't look too bad either. The only real issue so far is a sticking keyboard. Before I crack the case and check it out, are there any pointers on fixing the sticky keys, any caveats. Cheers Tom

cctech Digest, Vol 25, Issue 42

by Watzman＠neo.rr.com

> Paypal just blasted me warning that "my" paypal account is closed! > What? Closing a pretend account? I don't open paypal with them, for > that reason of this idiocity. I still have this silly "scary" email > from paypal for anyone to check. That E-Mail did not come from Pay-Pal. This was a "phishing" attack. The E-mail is completely phony, from a 3rd party who is trying to get your Pay-Pal user ID and password. If you click on the link (supposedly a link to pay-pal), you will go to a completely phony web site that looks EXACTLY like the real Pay-Pal site, and when you attempt to "log-in", you will have given your Pay-Pal user ID and password to a thief, who will then use it to access your real Pay-Pal site and clean you out, possibly to the tune of thousands, tens of thousands or even hundreds of thousands of dollars. Anyone who is "on the net" will get these "notices" from Pay-Pal, E-Bay and dozens of banks (with which they may not even have accounts). They are phony, and they do not actually come from the institutions. You ***MUST*** be aware of this and learn to understand that ALL of these a fraudulent attempts to commit theft of your identity. If you ever fall for even just one of these, you will be paying for and going through a living hell for a LONG time, perhaps years. The bottom line here is that if you get an E-Mail from an institution with a link, you just have to assume it's phony. If you are not sure, do not use the link, but rather long into the site's HOME PAGE (not the link) manually, and see if there seems to be a problem.
