Either that or HP managed to turn out a lot of some things in a week. It's also not clear whether a change in year/week resets the "counter" portion of the serial number. I'm not sure what option 008 is on a 2100A. > 7900A Disk Drive #1527A04334 > 2895B Tape Punch #1632A03303 FACIT model 4070 Yep, this is a badge-engineered Facit paper-tape punch. > 2748A Tape Reader #1133A01747 "System Serial 0815F" > 13215A Disk Drive Power Supply #1435A04338 "Option STD" > ?????

I am thinking that A9 and maybe A8 are options (DMA?), but will need to pull manuals to look. Likewise I will need to pull manuals to tell you more than obvious bits (e.g. DISC INT'F 1 and ...2 are how it talks to the 7900A) about the other things in row 1. Row 2 is where the memory lives. I am thinking that you have 32KW in that system; the XYDs should be the X-Y drivers, the SSAs should be core stacks, and I can't remember exactly what the ID (16K), IDL, or DC cards do. I do recall that there is also another flavor of the ID (16K) card for smaller memory configurations. There should be five-digit product IDs on each of those cards, most likely of the form 12ddda, where the "d"s are digits and the "a" is an alpha character. Those would help me when I have the manuals handy. Might even help me figure out which ones to pull. > The processor boards date to 1972, yet others date to the early 1980s. > Apparently this thing was upgraded (or repaired) several times during its > life doing secret things. > > OK, what do I have? Any input would be helpful. Well, you have more than I do in the way of hardware. My 2100A was part of a Fourier analysis system, and so I have some cards that do some sort of fast crunching on some sort of input signal, but all of the other I/O and memory was removed. So otherwise I just have the CPU cards. But I have manuals. Bug me, I'll pull 'em out and look through them and try to find out more for you. w/r/t the rack -- as near as I can tell HP used the same style of 19" rack for lots of stuff, from various 2100-based systems (including HP 1000s) to the early HP 3000s. I see them from time to time but they usually have been gutted already and are just empty racks. -Frank McConnell

Radio SShack Model 100 on AuctionWeb

by gmast＠polymail.cpunix.calpoly.edu

Hello, I'm trying not to buy too much more of this stuff but this guy made me a heck of a deal on a Model 100 along with a video camera I wanted. I put it in the auction. It's really nice and is still in the original box! Radio Shack Model 100 Laptop Computer (photo) Current bid: $42.01 Auction ends on: 09/28/97, 14:36:03 PDT http://komodo.ebay2.com/aw-cgi/ItemISAPI.dll?ViewItem&item=511656

On the hunt at Goodwill . . . .

by SUPRDAVE＠aol.com

Actually, I've had great success at goodwill here on the east coast. i picked up a complete platinum //e machine, a colour composite monitor with two undisk 5.25 drives, a trs80 model 3, an IBM PC RT, and the rare <?> printer attachment for my pc convertible and my uVAX II ! the pickings have been slow lately, but its always a luck of the draw kind of thing. i usually hit the stores about once a week and hope for the best. I regret not getting a plus/4 i saw in the original box last month. david In a message dated 97-09-22 23:33:48 EDT, Sam Ismail put forth: << Here's a hint for everyone...don't waste your time at Goodwill (well, usually). All the good stuff is at those for profit or non-chain thrift stores. Look for places like Thrift Town, Thrift Center, Thrift This, Thrift That, etc. I've heard that Goodwills take all the computer junk and auction it off. I never, ever find any computer stuff at Goodwills or Salvation Army's. I used to find stuff at the Salvation Army, and occasionally find some software (found an MSX cassette of all things at one recently) but never any hardware. >>

Help out Goodwill

by jrkeys＠concentric.net

This sounds like the Houston GW ?? I lived there a few years back and was a great place to find items. I like your help idea may try it here.

Sorry you feel that way as I find a ton of items at the GW, such hardware, manuals, parts (new and used), and software (new and used). The prices range >from .25 to 35.00.

Hell yes keep them! You never know when they will come handy, i wish i had a few lying around now. Great for Minix boxes to check your mail... As for the assorted cards, well i am going to use the mass of cards i have here to bolt into my stell shelf units as book ends (i am going for the "inside the mainframe" look in my apartment :) "Linux users are people who would convince you that 10 steps are better than one" ---------------------------------------------------------------- ______________________________________________Live from the GLRS The Man From D.A.D ----------------------------------------------------------------
