In any hobby, a price guide is both a blessing and a curse. When I owned a sports card shop I became aware of the potential effects of price fixing and other forms of market manipulation. Specifically, if the publisher of a price guide had a bunch of Don Drysdale and Sandy Koufax cards to dump, those players would book high until he dumped his cards. Additionally, advertiser pressure influenced prices listed in these books. For vintage computers, a price guide published 2-4 times yearly, listing maybe 500 computers, might work. It could be advantageous to only include photos for 50 of these computers in each issue, rotating through all 500. This would encourage people to buy the next issue, with photos of 50 *different* machines. We have Ebay now, and other auction sites, from which to draw data. The publication might also consider any documentable, verifiable report from private buyers and sellers when compiling the price guide. And since when can your average scrapper read, anyway? Just my two cents . . . Glen 0/0

Need a source and info on a memory chip

by rhblakeman＠kih.net

This is off topic but I know that someone in this list will have the answer. What I need is a surface mount memory chip for a PDA 16mb upgrade of internal memory. The chip in it is an 8 and I've seen a unit with a piggybacked chip on it with a jumper run from the Motorola Dragonball cpu (I basically drew out the mod on a Wendy's napkin it's that simple). Here's what's on the face of the present 8mb chip (the piggy back will be the same or suitable sub): ---------------------------- HYUNDAI GM71VS65163CLT5 0040 AG2 KOREA ---------------------------- It's a surface mount chip that is a 50 pin DIP package (2 rows of 25 pins). I'll need one initially and end up needing around 25 so I might as well get all 25 at one time. Does anyone know where I can get a specs and/or pinout of this and a good source for purchase of small or large quantity? I want the pinouts/specs for curiousity and the source obviously for purchase rreasons. Any help is greatly appreciated.

EISA - was VLB SCSI?

UTC Transformer type H-89

by acme_ent＠bellsouth.net

Ran across this on Ebay tonight: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1649083427 This transformer has a 115V primary, and several taps on the secondary ranging from 5 to 850 volts. What kind of device might require such a wide range of voltages? BTW (for those without 'net access) the device sold for USD103.50 and there were no details as to what this thing was used in. This leads me to believe that it's a high failure-rate component in a relatively expensive (and not uncommon) piece of gear. Any clues? Glen 0/0

OT: Determining TCP port ownership

by rcini＠optonline.net

Hello, all: I'm having a bit of a time with SNMP on my Windows NT box. I'm running the Compaq management agents which use ports 161 and 162. But, when the SNMP service starts, it complains that another program is grabbing the port. Using "netstat -an" tells me that something is grabbing the ports using both TCP and UDP. The TCP address shown is 0.0.0.0. I have no other obvious programs running that would be an SNMP server. Is there a utility that can tell me which executable is grabbing a given port?

EISA - was VLB SCSI?

by mhstein＠usa.net

Since I don't have any EISA experience other than this, maybe I'm missing something really fundamental... I assumed everything was handled by the configuration & diagnostic utility; is there something else I should be doing? How else can I get at the config info? mike ---------Original Message------------ Date: 3 Nov 2001 5:59:47 +0100 From: "Iggy Drougge" <optimus(a)canit.se> Subject: Re: EISA - was VLB SCSI? Since I've been reinitialising and updating my Proliant this night, I have some fresh knowledge. Could it be that you've left some pieces of the config >from when you still had the modem on the config partition? Any change in an EISA system has to be handled in the config partition. It's a real pain if you're experimenting together a system.

Am2901 bit-slice

by CLeyson＠aol.com

Hi everyone Looking for a source of AMD Am2901 bit slice chips ? Try Dial Electronics at http//www.dialelec.com. They specialise in obsolete parts, have no minimum order charge, you don't need an account and they will also ship worldwide. I've got a busted CPU board to fix so I've got a few 2901s on order. If I can't fix the damn thing I will probably end up building a bit-slice processor just for the fun of it. Any suggestions ? Best Regards Chris Leyson

One-off vs. One-of (was Re: CPU design at the gate level)

by Antonio.Carlini＠riverstonenet.com

> pete(a)dunnington.u-net.com wrote: > >I've never heard "one-of" before, only "one off" (and "2 off", "3 off", >etc) to describe a quantity. It's commonly used here, not just in >engineering. Agreed. I first saw it in Practical Electronics (which I started reading in 1977/78 or so). It was often used in the parts lists. It confused me slightly the first time I read it, but it was clear what it meant. I don't know the derivation off-hand but I am surprised that anyone uses "one-of" - it's just harder to say! Antonio
