Many collectors have multiple systems and peripherals that can be cannibalized for parts if anything in their primary machine fails, but what about maintaining an inventory of discrete components such as ICs or those 150,000 Mfd filter capacitors? I reviewed the availability of parts for many of my systems and found that most components are readily available. Others were more difficult to locate or were listed under another industry part number (e.g., a "25LS2521" is actually a "74LS688"). Do you think it's worth the effort to purchase spare discrete components? Are there any specific categories of devices or parts that are prone to damage, failure, or extinction?

Prices (Re: DEC PDP-11's, Peripherals, Docs, Unix, etc. for sale; L.A.,CA.)

by c-bristol＠usa.net

I'm sorry, I don't know what this stuff is worth. I bought my PDP-11 stuff when it was still worth something. I paid $5,000 for the 11/45, and $1,000 for the Emulex SC21/B1, to make a home Unix system in 1983. Just ignore my prices and make any offer. Did I hear an offer of $30 + shipping for the SC21/B1? ?? Buy the way, I already sold about 15 items (mostly stereo stuff) from this list at almost the prices I asked. So on the computer stuff, please ignore my prices, but try to pay me enough to crate it up if you are not able to pick it up in L.A. ---------- From: Zane H.

Well he did say he was planning on leaving the country! :^) Actually he's been trying to sell this stuff for quite some time, I first saw this when I was doing a search on 19" racks and DejaNews pulled it up, I think that was in July.

Nicolet 290 needs home

I have a funny feeling it has something to do with http://www.nicimg.com , which is what you get if you stuff +"Nicolet" into AltaVista. And since they're in San Diego, this computer may be on my turf, oh joy. __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California

Apple III+ questions

by thedm＠sunflower.com

Okay, where to begin: I have several ///'s but no plus, so needless to say, im jealous:) The AA's are factory, they go to the clock circuit to retain the time, some later regular ///'s had this as well. {clone pc's use this method as well, like old DTK's} The profile drive is more tricky, I have one too and it works. It is not a bootable device, you need a "catalyst" disk, that's the disk that runs the card and initialized the drive. It has some kind of menu system you edit to bring up like a dosshell kinda of thing to select items, This I havent figured out yet, when I go into the "catalyst editor" i get a file now found. Mine came loaded and working. I have alot of original software and docs for the ///, but not the ///+, but if I know my history right, they ///+ was just basically the version that worked :) ---------- > From: Zane H.

Goodwill Stuff

by gmast＠polymail.cpunix.calpoly.edu

I was at the Goodwill today and came across a couple interesting finds. The problem is that I'm trying not to accumulate any more of this stuff. If someone is interested in one of these, maybe we can work it out. I am in Central CA so shipping is kind of a pain for me. I guess you could make me an offer then I'll see if I can get it, then we'll do a deal. I'd just like to make it worth my trouble. I didn't buy these so if you're interested, send me an offer I guess. I'll cruise over there tomorrow and see if they're still around. Hate to see them get tossed. Email me before 9 AM PDT tomorrow or I doubt if I'll get over there again until middle of next week. TI 99/4 Expansion Module. Big heavy sucker. Has a floppy in it and an interface cable. Osborne Executive portable, works, KB, 5" (or so) amber monitor.

CC> Management suggestion

by engine＠chac.org

Since I've been on the list for a few days now, I'm getting used to the volume of the traffic, but I have a suggestion to make managing it a bit easier. Like most of us, I suspect, I like to segregate the received traffic so I can archive it. Why don't we take a leaf from CYHIST's playbook and start putting a flag at the front of the Subject: (as I did above) to make it easier to sort? This would be especially valuable for me since I receive both list and non-list mail from a few people.
