Sold a pair of old Jensen speakers to a guy in Korea the other day and am shipping them via DHL Worldwide. They have refused to accept the items until I come up with a "gauss reading" for the magnetic field???? Anyone ever heard of such a thing? I did a fair bit of research and found their maximum allowable reading is ".00525" but no one at DHL has a clue what that means. I'm assuming it is a measurement in gauss at some prescribed distance from the package. On average the strength of most high powered speaker magnets is in the range of 10,000 to 15,000 gauss, but that is measured at the voice coil [in the center of the field]. The field would decrease [as the square or maybe even the cube] of the distance. Stumped, Craig

Vax message as system locks up

by ncherry＠home.net

A while back I posted a message and mentioned a problem with the drives unmounting. Well here is the message: %SYSTEM-I-MOUNTVER, R7VEFG$DIA0: is offline. Mount verification in progress. After that I get a red line on the drive indicator and anything I on the console never returns. Any ideas? -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)

KA650 in MicroVAX BA123?

by jamesg＠PARRIMARK.COM.AU

I am relatively new to the VAX world, but I have already established that the very same thing was done to my MicroVAX by the previous owner... I have heaps of questions for the guy, but regretfully I inherited it from a deceased estate :-( What else was done as part of the MicroVAX II -> 3 upgrade?

Anderson Jacobsen ADC 300 modem

by jfoust＠threedee.com

On a recent surplus hunt, I picked up an Anderson Jacobson ADC 300 baud acoustic coupler modem for $1. What a beauty - it's in a wooden box with a flip-top lid and a brushed aluminum interior panel. It has two DB-25 connectors, but one is used to feed *in* the AC power (!). I haven't disassembled it yet. I did a quick web search and one turns up in Megan Gentry's collection. How old is this? It's serial number 759. - John

OpenVMS Hobbyist Install

by ajp166＠bellatlantic.net

From: Bob Brown <bbrown(a)harper.cc.il.us> >I see that the RZ25 is not supported to install the openvms 7.2 system to Dont tell my system that. It is supported. >(from the hobbyist cd)..would that explain the numerous parity errors that >I get when I try to install to an RZ25? (or is my RZ25 probably toast)... You either have the jumpers wrong or a bad drive (missing terminator?). Allison

Are >there MicroVAX III decals out there, is the >MicroVAX 3 decal unusual, or are both common? No, not unusual.Standard FS kits usually have all sorts of docs and rebadging material. What often happend was that someone would upgrade by attrition of another system or by ordering just what was required. With that you could have an assortment of markings. Allison

RS6000...I have one taking up space here - for donation/trade...

by claudew＠sprint.ca

Hi With all this talk about RS6000 servers, I would like to say I have a 320H 7012 type that has almost gone to the dumpster in the last two major basement cleanings I have done. It was removed from service and brought here. I booted it several times with the old AIX on there and everything was working. Plan was to put Linux on there...but then i learned it's not available...I pulled the 2 SCSI drives from it and never re-installed them. It was working last time I re-started it (3 months ago) with a Wyse 60 connected to the great modu10 serial connector (had to build an adapter plug - thanks IBM) using the diag/boot floppy disks for it that I have... No keyboard...no monitor...MCA arch...80Megs Ram, floppy, Token Ring network card, something I was told was a Sabine accel. video card (?), scsi card. I have no use or space for this. I would like to give it away or maybe at least get something in exchange...I collect micros from the 197x-198x...current wish list includes : trs80 mod III, NExT, Atari 800 or CP/M systems or anything else interesting...I am NOT looking for $$$ for this...I don't have the time to bother seeling it on epay, I am not even signed up to sell or buy on epay... One hitch : I am in Montreal, Canada. So if you dont want the whole thing (29 pounds on my people scale) or I can always just ship some boards, or whatever...I you need more info or pics, just email...I am not too familliar with the R6000 machines... Thanks Claude claudew(a)sprint.ca

NEC APC available

by jfoust＠threedee.com

Contact the person below, not me. - John : ::: : ::: Date: Thu, 12 Oct 2000 00:14:51 -0700 (PDT) From: pppmjs <pppmjs(a)yahoo.com> Subject: An Old Computer To: jfoust(a)threedee.com : : Hi there- I found your link thru a site on Computer museums. I have a functional NEC Advanced Personal Computer (APC) (1983) It runs with 2 - 8" floppies. Believe to have been built to run/assist by BridgePort CNC machines. Operating system is Dos 2.1 Have operating manuals & guides. (Got it to boot, but didn't get no further, as I'm not sure what some of the disks are.) I need to possibly get something out of this system...say $125-$150,or more if it's possibly a rare find(?), if in fact it's worth anything, I really don't know, but believe it would be. If your interested or know of someone that may be, please reply back. Thanks for your time Michael Salomaki pppmjs(a)yahoo.com __________________________________________________ Do You Yahoo!?

Here's one for the DEC engineers

by cmcmanis＠mcmanis.com

Well, I've got to give a toast to the folks in DEC Engineering, it may be that they had to deal with Field Circus screwing things up, but I for one really appreciate that DEC used keyed connectors, and appropriate cables, and sturdy hardware. I'm also glad that whomever designed the TQK70 did so such that plugging it in backwards in the Q-bus does it no apparent harm. I reassembled a VAXServer3400 after cleaning it and got the dreaded "E" in the display, after careful diagnosis (with the power on!) I noticed the TQK70's chips were on the wrong side of the board! (Is there any good way other than lying on the floor on your side to insert things into a BA213?) Powered off, pulled board, crossed myself and re-inserted it correctly. Voila, system boots and tape works fine. Cheers! --Chuck

Lisa 2 Keyboard/Mouse substitute?

Somewhere out there, there's fairly complete info on the Lisa hardware. It should include details, if not on the keyboard itself, on the interface to the keyboard. From that, you might be able to modify a spare Mac keyboard to work until you can find a Lisa replacement. Worse case, you'll have to use a microcontroller to convert between the two interfaces, requiring some custom work on your part. -dq
