There is an equivalent shielded (STP) cable but it's a slightly different impedance so it's not Cat5 standard. No, there isn't an official colour code, though many sites have a local convention. Ours is to use black for serial, purple for crossovers, yellow for student network, pink or brown for telecomms, and other colours ad-hoc to distinguish various subnets in areas where more than one is in use.

RISC manuals

by jfoust＠threedee.com

Because of the NatSemi 32000 manuals described on my web site at http://www.threedee.com/jcm/library/, I received this inquiry: "I am collecting manuals for RISC-type processors of the early 1990s. I haven't been able to find Power/Power 2 (the processor/s inside the IBM RS/6000 computers)... Why is that? " I know nothing of those machines. Can someone help me with an answer I can forward? - John

Cleaning up the list (was Re: Stanco della solita routine quotidiana??)

by acme_ent＠bellsouth.net

I second the motion -- this is getting ridiculous. I also volunteer to assist in moderation duties. Since I've run out of space, time, and money I have no desire to acquire any more machines, so I won't be tempted try to beat the list out of a fair shot at getting equipment offered by non-subscribers. And while I'm on a roll, here: Doc, how about coughing up the name of the list-member who tried to pull a fast one on you so that the rest of us can know how to deal with this person in future transactions?

Multiple floppies in one system?

by djenner＠earthlink.net

I'm putting together an old 486 system, one of whose main purposes will be to read/write floppies of several formats. Like 5.25" 360K, 720K, 1.2M, RX50, etc., and 3.5" 720K and 1.44M. I also want to be able to copy RX50s disk to disk on the appropriate drive type. So I figure it'll take 4 drives (or maybe 3 drives where one is a 3.5"/5.25" combo). All of these would be in one enclosure. The question is, how to do this without having to unplug/plug drives every time you want to make a configuration change? It would be nice to just be able to throw a switch or two to re-configure. Not having to get into the enclosure would be nice, too. I've thought of two ways to do it, but I'm not sure they'll work, or if there might not be a better way. 1) Plug all the drives into one control cable and switch on/off the power to the drives to select them. 2) Plug all the drives into one control cable and select the drives by switching a control line on the control cable. Any comments or suggestions would be appreciated. Thanks, Dave -- David C. Jenner djenner(a)earthlink.net

This is how I'd go, but the BIOS will only understand units 0 and 1, you'll need a device driver for units 2 & 3. Oh, and you'll need a *real* floppy interface cable, instead of the butchered IBM-style floppy cable that *every* PC I've seen has, except for the Zenith Z-150 family. -dq

Multiple floppies in one system?

by Gary.Messick＠itt.com

Joe, I think I remember using a Videologic DVA-4000. It was used to overlay NTSC video over VGA video. If I remember, you setup a specific color "block" through the VGA, and the NTSC came through that "window." Kinda like my understanding of Chroma-keying (sp?) Another thing it could do was overlay the VGA with "transparent" NTSC. We used it for demos of a ruggedized PC we were building at the time. It could do some impressive (at the time!) stuff. I don't recall the programming particulars, but don't remember it being that difficult. Let me know if you want further info.

I use Priority mail and order boxes by the carton. For me to turn a NEW box inside out and use it to ship some other way would be illegal. If my customer who receives a priority mail package, opens it and then reuses the box (by folding it inside out), I don't think they are breaking the law. Most of the Priority mail boxes use a glue to self seal. You then pull a tear strip to open the box. Technically the box is destroyed. However the small video tape size boxes really lend themselves to reuse by turning them inside out and taping them. I suspect this secondary use is not illegal. I call this recycling. Now a friend of mine bought a bunch of new USPS Priority Mail supplies in a lot at an auction. For him to use these inside out would be illegal even though he is not signed up with the Post Office Priority Mail. He was actually after the 26 pallets of new blank cardboard boxes with them which he sold on the secondary market. Paxton Astoria

SCSI options for PDP 11/23

An 11/03 backplane is already 18-bit. BDAL16 and BDAL17 are bussed so it can use parity memory. It's also easy to upgrade to 22-bit, by soldering wrirewrap wire onto the extra 4 lines, though any 11/23 or 11/23+ will work fine (as an 18-bit system) without doing that. I can't think of anything that will fail to work on such a system, apart from software that needs more than 124KW of memory, obviously. Specifically, I/O page access will work coreectly for any properly designed device, and RT-11, RSX-11, etc will just see it as a normal 18-bit system. Oh, and an 11/23 would work fine on a 16-bit backplane, unless you wanted to use parity memory. The MMU wouldn't be useful (you could take it out, though you don't have to; an 11/23 will work fine with 28KW and no MMU chip). -- Pete Peter Turnbull Network Manager University of York

DSSI support for NetBSD: request for docs.

by jkunz＠unixag-kl.fh-kl.de

Hi. Now that my RX01/02 driver for NetBSD and the accompanying "NetBSD device driver writing HOWTO" is nearly finished, I am looking forward for further challenges. I think will stay in the disk (and tape) department and write support for DSSI. I know that this is not a trivial task, but I will give it a serious try. So I have the usual problem: docs. I need docs about DSSI, the protocols that are used on it, the host adapter chips (SII and SHAC), MSCP, SCS, ... The KA6[46789]0 CPU and KDA50 / UDA50 programmers manuals should be a good start. So if this docs are online somwhere on the net, please give me a link. Thanks for your help. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

NEC applications processor

by rdd＠rddavis.org

Having what appears to be some sort of "applications processor" made by NEC, model 3401, class 5451, as well as another box labeled "class H6830-STD1-01-46," and not being able to obtain any information or documentation about this equipment, I'm not quite sure what do with them other than take them apart for parts. On the 3401, there are three ports labeled "LS Link," four labeled "HS Link," two labeled "System Bus" (channel A and channel B) and a diagnostics port. If anyone has a need for these boxes, or can provide me with any information about using them, then I'll consider not taking them apart, as tempting as that option is, considering that: they're taking up a fair amount of space, and have some useful ICs, wire, fans, PSUs, LEDs, memory, etc. inside, and the one case could be modified to hold several 5-1/4" hard drives and the PSU. I'd really like to find a way to use this equipment in it's present assembled form, however. :-) -- Copyright (C) 2001 R. D.

RX02 / DSD440 problem

Then it's possible that the drive to the stepper motor that turns the leadscrew is, er, screwed. It might only be one phase; if you can turn it easily by hand when it's powered up, then it's probably not being driven at all so look for a destroyed driver or lack of 12V (or is it 24V? ). If it tends to settle into certain positions and won't step but does sort of vibrate and isn't very easy to turn by hand when the power is on, it's probably just one phase; look for a blown driver transistor (if the drive has such) or a faulty stepper driver IC. It's also possible (though unlikely, in my experience) that one of the coils in the motor has burnt out. You can check that with an ohmmeter, comparing it to the working one. -- Pete Peter Turnbull Network Manager University of York
