Have you been to the landfill lately? It's not exactly a jumbled pile of things with dirt on top. You see, the landfill operator has tools. For example, the tractor-like vehicle with spiky metal wheels, the better to break the piled things up and spread them around a bit. That doesn't destroy the things as thoroughly as recycling for metals but it is likely to leave 'em pretty beat up. Think of it as something of a jigsaw puzzle for future archaeologists. Plus, here in Sillycon Valley there is (and has been for a few years) significant pressure to divert things away from landfill, mostly because the municipalities have been told to cut their landfill usage by 50% (relative to some years ago). Not only are residential (and one supposes commercial) users encouraged to sort out and separately bin certain recyclables, but trash also gets sorted to separate out some of the stuff that's not complete crap. Metals especially. -Frank McConnell

Dallas RTC chips (was: Ace

by qltypc＠nbnet.nb.ca

ok people i got this dallas 12887 thing beat, here it is. pins 2,3,16,20,21,22 are missing right. so 21 would have been clear real time clock. aka clear cmos on a motherboard. take a hacksaw an cut into the side of the dallas 12887 right in the middle of where the missing pins 20,21,22 are stop when you hit metal. take a jumper wire and short to ground. {mine was clear after i reinstalled it cause the hacksaw must have touched another pin} bago wango tango cleared the cmos. dave

building a PDP11 from the things you find at home

by healyzh＠aracnet.com

> > > Imagine different front panels depending on which PDP11 you software > > > configure... > > > > And none of them have the feel of the real thing... > > > > -tony > > Only if you miss the fan noise... > > Bill I've got to agree with Tony, my /73 in a BA123 is about as quiet as the Sparc 20 I've run simh on, in fact I think it's quieter. Given the choice between the two I'll take my /73 hands down! With it I've got a *proper* terminal, not some whacked out terminal emulation (hmmm, is this when I admit that the system console for the PDP-10 version of simh is a VT420). Everything behaves the way it should, and I've got a better choice of disks. On the emulator I'm pretty much stuck using RL02's, on my /73 I've got two removable SCSI hard drives, a CD-ROM (yes, I've a bunch of PDP-11 readable CD's), and I can use FTP and TELNET under RT-11 or DECnet under RSX-11M. Unfortunatly to get files into RSX-11M+ I've first got to boot to RSX-11M, and copy them over (unless of course they're on CD-ROM). Oh, and the LA75 display printer hooked up to the VT420 I use for the console comes in pretty useful! The only use I see for a PDP-11 emulator personally is so I can run RT-11 on my wifes laptop when we're on vacation (and then I've got to take a blasted external keyboard with me). BTW, that's why I'd been running simh on the Sparc 20, I was setting up my RT-11 RL02 packs. Where I see emulation as useful is when you need a laptop version of the system, or you just don't have a chance of getting the hardware (and/or don't have the space even if you could). There are also commercial situations where using a emulator makes good business sense. Oh, the other use, in the case of the PDP-8 emulators with front panel emulation, is so that you can see what you should be seeing when running diagnostics on a system you're trying to repair (when you've never used a PDP-8).

What's your coolest ISA card?

by ken＠seefried.com

> Probably the two most interesting ISA cards I own are an Iterated > Systems fractal compression accelerator, Wow. Dr. Micheal Barnsley (the guy who came up with the technology that later became Iterated Systems) was my prof at GaTech when I took what I think was the first IFS class ever taught. I worked in his lab for a while. He started Iterated after I left. > The other i860 board I wanted was the Hauppauge > 486 + i860 motherboard. Oh, yeah. I lusted after this one at the time, right up until we started looking at how, um, baroque the i860 really was. Did anyone ever actually use one of these? A company called Opus made a number of ISA cards with interesting coprocessors. I used to have an Opus 32000 ISA card, a National Semi 32016 coprocessor. It unfortunately got tossed out by a careless girlfriend a decade ago (along with my unbuilt PC532 kit...sigh). I'm pretty sure that Opus continued this line up to the ns32332; I don't know if they ever made one out of the ns32532. I recall someone made an ISA board with a Fairchild Clipper on it, but the deatils have faded away. Ken

Older floppies and MFM hard disks enjoyed two numbering schemes: some people labelled the four drive select lines as DS0 - DS3, while some people labelled them as DS1 - DS4. If your documentation refers to DS0 but your drive is labelled with DS1 - DS4, you just use DS1 instead. DEC's RXDX1/2/3 controllers normally used DS3 (in the DS1 - DS4 scheme) for all hard drives, and re-routed the signals on a distribution card to select the appropriate drive. This allowed you to move drives around without changing the links, much like IBM arranged all drives to use DS1 and a twist in the cable. > Finally, I must appoint that RT-11 and Unix detect that exists > at least one DL0 and one DL1 in the system, but they can't access > the 'bad sector info'.

There were three versions: the first two were BBC B era and differed only in the amount of RAM fitted (was it 256K and 1MB?). The third was renamed the Master Scientific, but it was just the same device with a new label. About that time, Acorn produced a Universal Coprocessor box, which was a box which looked the same >from the outside but had just the PSU and mounting sockets inside. It was intended to house the coprocessors designed for internal use in the Master 128. There may have been a version of the 32K to fit in it, but I can't be sure, and I seem to recall some technical problem with it. Of course, there was also the 32016 fitted inside the Acorn Scientific Workstation. That machine was a large box housing a BBC B or B+ mainboard, underneath a Microvitec colour monitor chassis, with swing-out panels to hold a PSU and a 32016 board, with two half-height 5.25" drive bays underneath, holding a floppy and an ST125, and a separate keyboard and 3-button mouse. The 32016 was the same board used in the ordinary Beeb 32016 Second Processor, with 1MB RAM. -- Pete Peter Turnbull Network Manager University of York

What's your coolest ISA card?

by Mzthompson＠aol.com

I don't about cool, but I was tickled to get these cards. I got a box full of ISA Appletalk cards, complete with cables, driver disks, and manuals. When a former employer decided to dispense with the Apple LaserWriter II, I asked it I could have it and the associated cards, cables, etc. They said 'help yourself'. Took a couple after-work evenings just to pull all the cards from various machines and recover all the cables running through our department. Rummaging through our department's vault found the original boxes, manuals, disks, and even a couple complete kits still shrink wrapped. :)) Mike

Some of the interesting features of the 8061/8065 were serial address/data bus. They wanted all the pins they could have for external I/O (temp. sensors, injector drivers, etc.) The 8061 used the 8096 instruction set, and the 8065 used the 80196 set. All the chips were proprietary, because of the stupid serial bus. They did however have a chip that would convert the serial bus to a standard Intel address/data bus. But I have never seen one of these outside of Ford. I saw some of the production code that went into these modules: It's a miracle your car starts at all. The hardware/software was "cookie cuttered" into the modules. I.e. this powertrain uses these injectors (hardware/software cut and paste), this crank position sensor (hardware/software cut and paste) this valve timing (software cut and paste). Hey how come this module doesn't work? (As you can probably tell, I worked in module testing!) I believe GM used mostly 68K derived stuff, have no idea about Chrysler. I have a friend that OEMs an after market engine controller to a major aftermarket company. It turns out at least for him, in the beginning, it was easier to figure out the inputs/output to the module, and tweak those values, rather than replicating the functions of the entire controller. He simply placed his module "in-between" the module and the engine, and he could pretty much play at will with certain functions while letting the OEM module handle things he didn't care about.

Hmm.. That would be my Vermont Microsystems CAD card. It's got a couple megs of memory, a Z80, and a 80186. Plus it was mostly hand built, with wire wrapping and hand soldering .

But K-Jetronic (CIS) isn't timed at all- every cylinder port is getting fuel at all times. The fuel distributor controls how much by the area of the slots exposed int he control plunger as it moves up and down in response the the motions of the airflow sensor. But then again, as you and others have observed, CIS debuted later than I thought... so I don't know as much as I think I do! -dq

what the hell.

by dtwright＠uiuc.edu

Well, even though I've already posted a couple times, I too am new to the list and thought I'd chime in. I live and work in champaign-urbana, IL, and mostly collect old UNIX machines -- I have a couple HP 735's, an HP 425/t, HP 300, sun sparc 2, 5, and 20, an RS/6000, and some other crap. Oooo yeah, I got a textronix model 31 electronic calculator recently, but haven't done anything interesting with it yet -- I just know that it works. If anyone has tapes for it, let me know, that would be fun to mess around with... I've known about this list for a while, and just finally got around to signing up a few days ago -- damn laziness :) Later, - Dan Wright (dtwright(a)uiuc.edu) (http://www.uiuc.edu/~dtwright) -] ------------------------------ [-] -------------------------------- [- ``Weave a circle round him thrice, / And close your eyes with holy dread, For he on honeydew hath fed, / and drunk the milk of Paradise.''

Sparc2...FAILURE: No Trap Taken, Exp Trap Type - 00000009...Solved...simms in wrong banks...now more questions...

I have a question. I have a Sparc2, 64mb mem, 2x4gb barracuda's. I got a hold of a sbus 10-100/scsi card and tried to install it. When it comes up, no beep, no screen. I'm figuring that it's not compatable but i would like to have someone tell me for sure. Is there anything I can do? I've unhooked everything. No Joy.

Personal Computer World magazine: an 8080 puzzle and "Z80 is dead"

by celigne＠tinyworld.co.uk

The Letters page of these magazines are as interesting as some of the articles. Of course, when we're talking about over 20 years ago in a hobbyist magazine, the letter-writers of one issue were quite likely to write articles in the next. Two extracts for you. >From David C. Broughton of Northwood, Middlesex, in the November 1978 issue: Here is a little puzzle to test your readers' 8080 machine ingenuity: "Imagine you possess an 8080 with 64K bytes of read/write memory which you want to clear. Write a program that sets all 65536 bytes to zero." >From P.F.T. Tilsley of Loughborough, Leics., in the May 1979 issue: The choice of the Z80 for a home system at this time is perhaps a little rash because of the choice of 16 bit processors making their appearance. A better choice would probably be the Z8000 which is due to be available in the next few months. Three years later, I still bought a Z80 system. Ho hum. Regards, Paul

DOS for S-100?

Marvin <marvin(a)rain.org> wrote: > Has anyone heard of DOS being available for the S-100 platform? Yes. Seattle Computer Products sold 86-DOS (with their 8086 processor card?). As Chuck mentioned, Godbout/CompuPro/Viasyn and/or Gifford Computer Systems sold a pre-customized version of DR's Concurrent DOS. This could support multiple users on different terminals, as well as one user on a CompuPro PC VIDEO card that provided a CGA-flavor display and IBM PC keyboard interface.

Datasystems Design Board + RX33 floppies

by xds_sigma7＠hotmail.com

For what it's worth, I have the manual for the DSD880... I can say for a fact that it is like Jerome described, a big honkin' box with an 8 inch floppy and a Shugart 10MB 8" disk drive, as well as custom microcoded logic... The DSD440 is similar, but the one I had contained 2 8" FDD's and a board covered in Intel 3000 series bitslice logic... So I do indeed doubt that it could control anything else.. I do have another board that I want to get rid of, with manual, that I seem to recall will control 5.25" floppies, e-mail me if you might be interested, Sergio. I don't mind shipping it across the water ;p Will J _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

MCA systems

by technos＠crosswinds.net

Of the original lot of eight systems I bought, one was lost, crushed to less than half the original height in most places by a moron forklift operator. Seems he was trying to stack a frame from an IBM 982 on it. Really comic. The faceplate snapped into fifty bits, the cdrom collapsed, the floppy was flat. Plugged it in, straightened the VGA connector with a screwdriver, kicked it a few times (memory had become unseated) and it booted DOS.

MCA systems

by technos＠nerdland.org

A couple days back, there was talk of using PC systems with MCA busses to identify and test commercial cards (AS/400, etc). I've got a few, IBM PS/2 model 76S. They're cheesy DX2-66, but they're tested and running well under OS/2. Was going to use them as a test cluster, but my source of cheap MCA periph dried up. They come with 500M SCSI drives and either 4x slot load CDROMs or 16x drives I have left over from some AS/400 I scrapped. If you'd like one for testing, free to good home for those that live in MI and cost of shipping to those that ain't.
