Hello David, I finally got at that info you requested. It turned out that there was some other related info that I thought you might like also. Probably more than you've ever wanted to know about SCSI, up to SCSI-3 info? Of course it was being stored on a SCSI drive that, at the time, wasn't hooked to this system, which is why I asked for your patience. Anyone who is interested must DL and save it within the next couple of days, as I have very limited web space and can't leave it there long. This is the only time I can post it. So, perhaps someone else with more space can host it for a longer period of time. http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi-info-15kb.htm http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi_faq-145kb.txt http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi2-spec-1632kb.txt Sincerely, Bennett

Slightly OT: What to do with a DEC 3000/300?

by ken＠seefried.com

Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X (175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production. I'm fond of it, but probably more for the fact that it comes in a rackmount sled, which appears to be quite rare. It fits nice at the co-hosting facility (it's www.thistle.com, but it doesn't talk to anyone but me right now). What I know: Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM slots, but it will only accept 8MB, true parity, generic SIMMs (giving 64MB). And it's damn finicky about those. My 3000s spits on SIMMs that everything else in the basement has no trouble with. It will also accept Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that I've found will work, but that could just be me. If anyone has any of these SIMMs they don't want, do let me know... Video: AFAIK, none of the free *nix systems support the built in TC frame buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and display to another machine. Real men do serial consoles anyway. Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one of my PPro 200s for (other than the swanky rack-mount sled). Definately useful for low volume web, mail, etc., but "make build" isn't pleasant. My PC64-275 is way, way faster, but still not that fast. There's lot's of good info out there, and I know there are people working to support all that isn't currently supported. Drop me a note if anyone wants to know anything else. Ken

The stringy floppy is flawed the same way an 8-track audio tape is -- it only moves in one direction. As a result, A&J didn't write any OS for their drives, just a couple of simple commands.

Cromemco Pick-up on 10-13-01

by jrkeys＠concentric.net

This pass Saturday was a long drive MN to IL (12 hours total drive time) to pick up 2- Cromemco System Three's, a Systemv CS-300, one new in the box KB for these systems, lots of manuals and software for them, a Cipher 1600BPI tape unit, a model BRZ-III fan for the units, and some parts. All will have to be cleaned up as they are pretty dirty and need some loving care. The guy had over 1600sq feet of computer stuff he is selling most on eBay.:-( At a local thrift I got some Sega master stuff, like the 3D glasses that have been selling on eBay for $50, I got mine for a couple dollars. Got a Virtual Boy system for $11.99. Got some Atari 2600 stuff also they were selling cartridges for 80 cents and they had two big boxes full. Now I will start the clean-up and entering all the info into the database (my paper notebooks). Keep computing John

RS6000 7012-320H

by cmurillo＠emtelsa.multi.net.co

Today I came by an RS6000 7012-320H (Powerserver 320). On topic, since it was introduced in '91. It seems to have 16MB RAM, a SCSI card, an 800MB HD, 25MHZ cpu and a 8-port serial card. No framebuffer. There was an 8mm tape unit that came with it. Oh, and, >from what I can gather from the IBM web site, it is missing some sort of "ethernet riser card" which seems to provide the means to drive enet starting from a network header on the mainboard. I should be getting some of the terminals that were hooked to this beast. However, I have neither keys nor AIX install media. So I have several questions: 1) Which OS' (besides some old version of AIX) run on this box? Or, if I am stuck with AIX, in addition to praying that the HD is still alive, how could I break in and change the root password? 2) What exactly is this "ethernet riser card"? Do I have a network-less system? 3) Late last year, I posted a message to this list about some SIMMs that I grabbed off an AS400 system; they look like 72pin SIMMs but have a slightly different form factor and won't fit in a standard 72 pin socket. The thing is, they seem to fit the sockets in this system. And, that AS400 was equipped with exactly the same model of HD that this RS6000 has. So I am wondering if those 4MB SIMMS will fit this system, which is filled with 2MB SIMMS... carlos. -------------------------------------------------------------- Carlos E.

Well, the idea is this; Simple three line basic prog running on the calc, doing 'input#' for data from a sound card. The encoding format is kind of documented as is the text->bin conversion. There are already a pair of programs that will handle conversion from wav->bin->text or bin->wav, just not text->bin->wav.

Half-duplex VT420?

by optimus＠canit.se

Since I'll be running another headless computer (HP 9000/380), I brought home my VT420. Nice terminal, but unfortunately this specimen will only talk, not listen. At first, I suspected my HP had lost its settings (the stupid boot PROM must be set via the keyboard to use a serial console). I proceeded to bring my HIL keyboard home and set it (without any screen) to use a "remote" console again, and the machine seemed to acknowledge that, beeping happily. But no response >from the terminal. So I tested it with my DECstation. No response there either. So I hooked it up to my Amiga. Typing at the keyboard, there was output in NComm, but doing the opposite didn't work at all. So we have only one-way communication. What could be the problem? The cable works fine, I'm getting -- En ligne avec Thor 2.6a. Allt ?r under kontroll, och caps lock ?r bredvid.

ATM would be good, and although there's a lot of it around, you should be able to pick up a couple of routers fairly cheaply. Acorn Econet? There's Linux support for that too. How about the original DIX Ethernet? Try a web search for Aloha. Sinclair (Timex) machines like the Spectrum and QL used a proprietary network, but I think the only other company to ever use it was ICL. Do you count ADSL, ISDN, X.21, or just LAN stuff? 10base2, 10base5, 10baseF (and FOIRL), 10baseT, 100baseTX, 100baseT4, 100baseFX, 1000baseTX, 1000baseSX, 100baseLX and 1000baseCX are all closely related and you will find some excellent references at http://www.techfest.com/networking/lan.htm 10base2 and 10base5 are bus topologies using 50-ohm coax; 10baseF (and its predecessor FOIRL), 100baseFX, and 1000baseSX/LX are fibre technologies often used as point-to-point but can be used in star networks too; 10baseT, 100baseTX, and 100baseT4 use UTP and are normally used in star topologies. Before you get too carried away, you might want to think about the permutations of protocols, technologies, and topologies or you'll need a much larger house :-) The same fibre that carries FOIRL can (if it's the right size, 50/125) carry 10baseF, 100baseFX, 1000baseSX, ATM, FDDI, ... I have a thin Ethernet (10base2) segment, a thick Ethernet (10base5) segment, a lot of Cat5e carrying 10baseT and some 100baseTX, a chunk of FDDI, some FOIRL, 10baseF, and potentially 100baseFX, at home; and there's lots of redundant ATM kit at work but (a) I have no room, and (b) I'd have to buy it (which is against my religion). I also have some Econet, ISDN, UUCP serial links, etc. -- Pete Peter Turnbull Network Manager University of York
