Some things for sale - update

by MTPro＠aol.com

Hello, with everyone's patience, I would just like to offer that I now have a list of mags for sell, please e-mail for list. Also, here is more detailed info in order to sell the following: Generic, non-front-panel S-100 system with cool smoked plexiglass cover/case Dual 8" disk drives in chassis ADM5 terminal Please see: http://members.aol.com/mtpro/s100.html Also: Amiga 1000, monitor, external disk drive - complete system IBM Convertible with printer in IBM carrying case, disks, manual, works but screen does not display properly now Osborne 1, slightly newer OCC1 model with blue face front and keyboard top, looks great, excellent display, but can't get it to boot, all "boot errors." Drive needs cleaning, adjustment, replacement? Or are my boot disks just bad? Amstrad PPC640, seems to work, ready to boot, no disk, plus contrast does not work and hinge needs repair on display Most excellent Apple /// complete system with booting Apple Profile hard drive! I am motivated to sell, will definitely sell for less than eBay prices, but I'm not giving things away for next to nothing. Please offer reasonable offers. Thank you, David Greelish

DECnet/E and DECnet-Plus

by healyzh＠aracnet.com

I've *finally* gotten the network problems I've been fighting at home resolved. It looks as if my Intel 10/100 24-port Switch has decided that it no longer wants anything to do with 10Mbit <sigh>. Anyhow, I've moved my home network back to my old 8-port 10/100 hub and a 8-port 10Mbit hub, and everything is happy (thankfully the 24-port is serious overkill at the moment). As a result I now have managed to get the VT420 on the DECserver 90L+ to reliably talk to my DEC PWS 433au, and my Ethertalk-to-Localtalk converter is working again so my VMS server and Mac can once again print. Life is good. Now that things are straightened back out, it's time to get back to something fun, namely getting my RSTS/E system talking on my network :^) During the network issues I managed to get DECnet/E installed on my PDP-11/73, and had managed to do a directory listing (unreliably though) of the RSTS/E system. I'm now able to reliably list directories on the RSTS/E system. More importantly I have LAT working, so I can log in from my DECserver!!!! What isn't working is the following: Getting a directory of the VMS system from RSTS/E Copying files between the two systems Logging in from one system to the other Has anyone tried getting a system running DECnet/E (Phase IV) to talk to a system running DECnet-Plus?

DEC's Organic Illumination Systems research

by rdd＠rddavis.org

For info. about some of DEC's more unusual research: After accidentally happening upon an interesting humorous web site, http://www.petting-zoo.net/~deadbeef/archive/, I discovered the following written by Mike Olson <mao(a)illustra.com>, back around 1989. Interestingly, the following URL is still reachable (it does get redirected, however). You will recall the DEC WRL technical memo of several months ago called "Characterization of Organic Illumination Systems." That work is described at: http://www.research.digital.com/wrl/techreports/html/TN-13/ due to budgetary constraints, the DEC WRL research team was constrained to running just a few experiments on just a few foods. Fortunately, DEC's semiconductor engineering group has carried out further experiments, and has discovered that at 140V RMS, kim-chi acts as a rectifier.

Sun MBus & SBus stuff

by classiccmp＠crash.com

> What is an SM91? I've not heard of that one! According to the Rough Guide to MBus Modules it's only a 90MHz SuperSparc II. I haven't played with 'em in so long I don't recall if they're really 95MHz or not. Re: heat and the SS20 -- yeah, I started pulling DIMMs out of it on a hunch. ;^) Still wedged, and I wandered off to some other project. > Putting together a SS1000 ... aren't that big Oh yes they are. I mean not compared to a 19" rack, but this thing is huge for a non-rolling box and has to be over 80 pounds. I didn't realize what a pain it was going to be, and am wondering where to put it... The middle of the living room really isn't the best spot. I'm also looking forward to this huge machine running off of a tiny little lunch box (Sun 411) for storage... --Steve.

new find: Sun Ultra 10

by rigdonj＠cfl.rr.com

Mike, ONE of today's finds :-) Also got three SUN SparcStations 20s and a SparcServer 20 with some extra cards in them. Also lots of odds and ends.

It has four sticks of Kingston KTS7030/512 memory. I looked them up online. Each pair is 512Mb so that means it has 1Gb of RAM! The hard drive is a Seagate Barracuda II model ST320420A. That's an Ultra ATA/66 8.5 mS 7200RPM 20.4Gb drive. It's not SCSI but it will do! The CPU is PN 501-5040. That's a 300 Mhz UltraSpark IIi CPU with a ceramic CPU and 512k cache. It's not the fastest thing out there but again, it will do! Now where can I find Windeos for this thing? :-) Seriously, I found an Adaptec AHA-2940W/2940UW PCI SCSI controller today. Will it work in the SUN? Joe Joe

Sun MBus & SBus stuff (was Re: new find: Sun Ultra 10)

by classiccmp＠crash.com

> Of course what I drool over are the dual 50Mhz M-Bus modules I've got an SS10 running an SM52 (501-2780 IIRC) that's been doing yeoman service for the past eight years at least, 24x7 by 365. (It lost *both* disks just two months ago, so I feel relatively safe tepting fate like this ;^) I've got another SM52, but this 501-2444 doesn't play nice with the other SM52 and may in fact not work properly at all. Never got back to checking it out... I'm still tickled at having a pair of SM91's - I'd never seen any 'til these showed up on eBay. Got a late PROM for my SS20 and brought 'em up, but it kept crashing when I wasn't paying attention, so they're waiting for more round tuit's to accumulate. > I'm always interested in SBus stuff, even if only to > turn green at cards others have :) Don't know if turning funny colors is called for, but my favorites are the SWIFT combo cards - hme 100baseT and a "fast" wide SCSI interface. Oddest one I've got is a Parsytec BBK-S4 Adapter - lets an SBus system talk to Transputers. Of which I have none, but I guess it's good to Be Prepared... Has a T222 'puter on it, but there's no software in sight. I suddenly doubled the number of SBus cards I own when I was picking up SS1000 system boards. I've got hold of 8 SM81's to load up an SS1000, and three of the later "E" system boards, and am hoping that it'll all work with a non-"E" enclosure/backplane. That thing's heavy, I don't relish having to swap it to make that happen... If anyone's sitting on a CompuPro NS16032 board & docs and wants a bunch of SBus or Qbus stuff, let me know. --Steve.

New (sic) 8" floppy media?

by tomj＠wps.com

So, what's the story with current-use 8" flop media? My brother Gregg got my old CP/M system running, novelty is wearing off and is willing to part with it now :-) It's a homemade box, I forget what's in it, though I do remember it's got a Cromemco 4FDC with a data separator piggyback board from a Trash 1 living under the WD17xx chip (the Pertecs the 4FDC was meant for had data sep on-board). Two Shugart drives with solidstte relays to shut 'em off after inactivity, which is just as well, as the bearings now howl like crazed tiny animals. I have one sealed box of Dysans (list price: $65. My price: $2 from a stationary store in Tucson AZ closing in 1998. Wish I had bought 'em all.). How does this stuff hold up? I assume no one actually makes them anymore!
