Large (?) DEC 2000/x cache in Boston

by fdebros＠verizon.net

Folks, I have the spring cleaning derwish on my back: I have about 8 decstation 2000/x most of them loaded with ram! plus monitors plus cables, kbds, tapes, cdroms and networking and of course expansion boxen to get rid of plus 3 vlc4000 and manuals galore plus an infoserver vax and a vs3100...i think. These are located in downtown Boston. All would fit in a Suburban, just about. better in a van. the only rule: no cherry picking. Any interest now that the MIT swap is back on?

Front panel controller

by GOOI＠oce.nl

Alright, I am awake. Several of you are heading to bed ... I will give a short description of my project, then you can decide for yourself which way you want to go. Warning! Sort of longish reply ahead! My design consist of 2 boards, one is called "Core", the other "I/O". Both boards are almost Eurocard size. Power supply: only +5 Volts. Features of the Core board. --------------------------- Chips: 6809, 6821, 6850, 6264, 27128 and 27256, in words: the CPU is the 6809 which is a 8/16 bit quite powerful CPU which has good high-level language support (think of C), and you can read more abt the 6809 in an other recent thread. The 27128 is 16k EPROM at memory C000-FFFF, of which half is filled with a debug monitor and software to control the I/O board. The 27256 is 32k -optional- EPROM at 4000- BFFF. The 6264 is 8k RAM at 2000-3FFF. The 6821 (2x8bit I/O) forms the buffered interface to the I/O board(s). Last, the 6850 is the ACIA, which makes the serial (9600 Bd) connection to *any* host computer. On board level conversion makes it a true RS-232 port. The ACIA and the PIA are mapped in $0080-$00FF, that is legacy from the design around the 6802 (RealConsole Mk I). The serial port can be connected to a terminal (e.g. VT220) and you use the monitor to debug your own (assembler) programs. Or you connect the serial port to a PC, SUN workstation or whatever and control the "thing" via the serial port. My application for it is to control the I/O that drives LEDs and read switches from a home-brew console. I have made some patches in SIMH, and I can *boot* RT11 via my console as if were the real thing. See www.pdp-11.nl , click in the left menu on "homebrew PDP-11". On the opening page click in the top section on "SIMH software", "new design" and "action!" for more ... Features of the I/O board. -------------------------- The I/O board has 3 LS138 (1 to 8 decode chips) and octal latches (373 and 374). One I/O board can have up to *eight* 8-bit output ports and *eight* 8-bit input ports, thus there is on one I/O board 64 outputs and 64 input available, enough to drive a full PDP-11/70 console. The I/O board is connected to the Core board with a simple 20-wire flat cable. If what you want to control is bigger, or perhaps totally different, you can cascade (theoretically) up to 8 I/O boards by just running that flatcable from I/O board to I/O board. A single jumper on the I/O board settles the addressing issues. The practical limit of I/O boards is six (due to fan-out load issues), but if you insist and go outside specifications I guess you could get away with 7 I/O boards. Applications for the Core and I/O board. - First, the mentioned console, but *NOT* limited to PDP-xx/xx consoles! Think of the IBM S3; not a small one, but it can be connected. The console can be home made, but if you have a *real* console laying around, that can be connected too! (I'd prefer a real console to go with a real machine tough ...) - Why limit to "blinkenlights" consoles? You can just as easy connect it to the more modern console like the 11/34 or 11/60 ! The control of the 7-segment displays is of course in software not with hex to 7 segment decoder chips! - Use some I/O to make a parallel I/O port (if you need it). I am not sure if the speed will be sufficient to connect an IDE drive (in PIO mode 1), but that is something I intend to try ... - Whatever project to wanted to do! There is enough I/O capability ... The monitor software is described on the site mentioned. If you know the Motorola Mikbug monitor, this will look familiar. The RealConsole software controls the I/O ports. The input ports are read periodically in an interrupt service routine. The *debounced* data >from the switches is stored in memory locations, so your application can read the switches from those memory locations. Several "hooks" (in fact small subroutines) allow you to control any bit of any output port. There are a few 'special' routines to handle the issues involved with momentary push-buttons, toggles. A depressed toggle and then released would mean that in memory that specific bit would be set for a brief moment and then be reset. To solve that issue, you can specify via a hook on which input port(*s*), which bit(*s*) are connected to toggles. Those bits are processed differently. Once set (by pressing the toggle) that bit remains set until you command (an other hook) to return to zero. So, you can process each toggle when you want, and when that is actually done you reset the "toggle". Some "higher" level commands are e.g. "Axxxxx" where the "x" is a hex number. This command will put xxxxx on the Address LEDs. Likewise, there is a "Dxxxx" command. You figure out what it does :-) Project status -------------- The project was ready to go manufacture the lay-out PCB set prototype tpo build it and check if it does not contain errors. This week I am working on the "upgrade" from the 6802 to the 6809 CPU, because of its better availability. Performance improvement etc. are a nice side effect of this move. When the prototype is checked (within one month), the board sets are "mass produced" in the US. Silkscreened, solder mask, etc. - professional quality. To keep those costs low, it takes 5 weeks to get them made. (could be done in a few days, but don't ask what the compay charges!) You can order the board set (or more I/O Boards than Core boards) either bare, or together with the "difficult" chips, or as a complete kit that contains all components. I am not going to make much profit on it, but when more people join the bigger discount we can get on the parts! For those who rather not solder the boards, I am prepared to do that work and test them (for a fee though). I will write a "manual" that described the software, give a step-by-step DYI building the boards (with fotographs), connection diagrams, multiple I/O Board configuration plus the fan-out load calculations. >From my site you can download the software source code and the changes made to the current version of SIMH. Believe me, I am dedicated to this project! As Vince said, he did the PCB design and solved the routing issues. We try to buy the parts as cheap as possible, so those will probably be bought in the US and not where I Live - The Netherlands. We are working on how to ship it all. It is a little stupid to ship many parts from US to Holland, assemble the kits, anmd the send back some 70% of it all to the US again ... If you have any questions regarding this project, ask! I will try to give an answer as good as I can, as soon as I can. I will help thinking about your specific application. For example, one guy asked for the possibility to connect an 8-bit input port directly to an 8-bit output port and use the combination as a bi-directional 8-bit port. The final idea was building a setup to test M-boards! (BTW, the answer is yes with a minor patch!) kind regards, - Henk, PA8PDP gooi(a)oce.nl

Z8000 parts question

by David.Kane＠aph.gov.au

Only a very minor detail, but I beleive that the certain Zilog chip designations also indicate the max clock speed. For instance the Z0800110PSC is a Z8001 (Z08001.. portion), with a max clock speed of 10MHz (..10.. portion), and the PSC indicates a palstic DIP package. So I would guess that the CPU, clock generator, and MMUs are 10MHz, and the Z-CIO is 6MHz. The Z-SCC is probably an older chip that predates the current Zilog chip designation standard. > Z0800110PCS CPU Central Processing Unit, 4.0 MHz segmented version (8 MB addressing). > Z08030AB1 Z-SCC Serial Communications Controller (dual channel), 6.0 MHz. > Z0803606PSC Z-CIO Counter/Timer and Parallel I/O Unit, 4.0 MHz. > Z0801010PSC Z-MMU Memory Management Unit, 4.0 MHz. > Z0858110PSC Clock Generator and Controller, 6.0 MHz.

Helping a Neighbor - Need Syquest SyJet (IDE) Driver SQATDRVR.SYS (DOS)

by patrick＠vintagecomputermarketplace.com

I'm helping a neighbor who's helping a neighbor. He's trying to get a Syquest SyJet IDE drive running under DOS (the neighbor->neighbor has a bunch of DOS games she loves to play). Does anyone have a Syquest SyJet IDE driver for MS-DOS? After a bit of Googling, it would seem the file might be called SQATDRVR.SYS. It's possible to set the BIOS parameters so the drive can be seen/read that way, but cartridges can't be removed when it's done this way. Apparently the driver facilitates that. If there's an accompanying utility that mounts and/or dismounts the volume, I suppose it would be necessasry to have that too. TIA! --Patrick

Need help with Sparc-1 (SUN)

by dave04a＠dunfield.com

Hi Gang, Recently acquired an old Sun SPARCstation-1. It boots! - but I don't know the root password - Guy who gave it do me did so because he was moving, and I can't locate him now. Got Solaris 2.6 CD/docs with it, so I figured I'd just reinstall a fresh system. Can't get it to boot from CD. When I power on the system, hit STOP-A to get to the boot prompt, then do: boot sd(0,6,2) It thinks a while, then I see one access to the CD, and I get the message: (From memory so not exact quote but pretty close): "The magic character in the label is incorrect. The file loaded, but it does not appear to be executable". Tried everything I can think of, but this is the only response I am able to get which involves any CD activity at all. Same procedure works perfectly on a Sparc-2 - boots right up off the CD. I'm assuming that this CD works on the Sparc-1, because A) it came from the same source at the same time (not a guarantee), and B) It's GOT Solaris 2.6 already booting on it (I just can't login) - I'm guessing that it was installed from this CD. Also tried a Solaris 2.7 CD that I have onhand - exactly the same result. Anyone have any insight to offer?

QBUS block mode timing question

by vax3900＠yahoo.com

When the bus master requests block mode DMA, it inserts BS7 when inserting the first DIN. If the slave is capable of block mod DMA, it inserts REF when inserting RPLY. The master removes BS7 when inserting the last DIN to finish the block mode DMA. My question is, what will happen if the master finishes the DMA cycle early? The same question is, what will happen if the master keeps BS7 inserted when inserting the last DIN? Will the slave malfunction? It seems a small violation of the protocol. It seems the bus master needs to predict the availability of Data otherwise. Thanks. __________________________________ Do you Yahoo!?

Z8000 parts question

by rigdonj＠cfl.rr.com

Today I found a big stack of computer cards with Z8000 CPUs on them. The Z8000s are socketed and I planned on grabbing them. But I'm wondering if it's worth the trouble to take the related parts off? They're all soldered on so they'd take more work. Besides the Z0800110PCS CPU, the others are Z08030AB1 Z-SCC, Z0803606PSC Z-CIO, Z0801010PSC Z-MMU and Z0858110PSC. Any thoughts on this? Joe

soldering iron & advice for magnifier

by swtpc6800＠comcast.net

I have been using a Metcal soldering station for over a year. (Model PS2E) My previous unit was a Weller WTCPN that I used for 20 years. The Weller is OK but nothing like the Metcal. The Metcal gets up to temperature fast (seconds), this means you can change tips for one solder connection. There is a rubber pad for removing hot tips. It also holds the temperature under heavy use. Get a Metcal. The Weller WTC series uses a magnetic tip to control temperature. When the magnet heats up it loses strength and the heater switch opens, when the magnet cools down the switch closes.. This works but it makes it difficult to solder jumpers to restore cuts in PCB traces. Capacitor leads are often made of steel. The lead wants to stick the tip. Another thing is the WTC irons produce a lot of electrical line noise as the heater power cycles. In the early 1980s we were designing a digital instrument that would reset (lockup) when used on the same power circuit as our soldering irons. Seeing as how most of our customers would have a soldering iron next to our unit we had to fix this. We rigged a Weller WTC soldering station with the iron replaced by a relay that cycled on and off as a noise generator. A power line filter on our instrument fixed the problem.

TCP/IP setup under Ultrix on an 11/84...

by julesrichardsonuk＠yahoo.co.uk

We have a usable RA81 drive for the PDP 11/84 now (whoo!) and stuck Ultrix (3.1.1) on there earlier. The machine has a DELUA Ethernet board in it - not the DEUNA or DEQNA boards mentioned in any of the docs that we have. Anyone know if the board is supported with that release of Ultrix? If so, presumably a kernel rebuild is needed to enable support as it won't be built into the installed kernel? We added in the optional TCP/IP code during system install, but info on the 'net as to how to get networking up and running on these machines seems very thin on the ground. I found the 'netsetup' script but of course that still doesn't give us an actual device in /dev for the board. Any ideas anyone? cheers Jules

PDP8s for sale

by tandem＠comcast.net

Here's the list of stuff that I've got for sale. I'm located in the Kansas City, Missouri area (USA). If someone showed up with a truck & some cash, they could take it all for one price. I don't really know what this stuff is worth now, however I do remember how hard I had to scrounge to get stuff like this back in the 80s. So make me an offer. You pay all shipping costs.

In Memoriam: Sipke de Wal

by waltje＠pdp11.nl

All, It is with great sadness that I have to announce the sudden and very untimely death of Sipke de Wal (the Xgistor) of Noordwijk, The Netherlands. After a brief period of dealing with an extremely malicious form of cancer, his body decided to give up late yesterday afternoon, May 13th, 2004. About 15 years ago, Sipke got me started in the PDP-11 collection "biz", when I had to get rid of my 11/40's, /34's and associated periphs. My uncle had a friend (Sipke) who'd probably take them, and, sure enough, he took them in. When I saw his place, filled with all sorts of old computers, I decided to "do that too when I grow up". I still have the MicroPDP-11 he gave me then. Last week, I got forwarded a message of one of his friends, asking for a new home for a (PDP-11) computer collection, because the owner had gotten seriously ill and had to let go. I was the first to respond, and "got" the collection. Sometime later, I started to realize that the list of equipment sounded familiar. When the intermediate friend told me that the owner lived in Noordwijk, all alarms went off. Some checking (I called his number) clarified things.. indeed, it was Sipke's collection, and he indeed was very ill. Still.. we hoped for some more time for goodbyes, a chat, and so on. I'll be taking care of his systems, which, as he put it, with a smile, "were kinda overdue in picking up, after 15 years!" Rust zacht, dear Sipke, and watch your blinkenlights go! Sipke's site is at http://xgistor.ath.cx/aboutme.htm.

SPARC-5 memory?

Also got a SPARC-5 - indeterminate condition - no drives - no memory. Can anyone tell me what I need for memory in a SPARC-5? I know there are different versions of the S-5 - here is the info from the label on the bottom: Model number: 544, Service code; 55, PN: 600-3853-01 SN: 546F0085 The board has 8 168-pin DIMM sockets at the front lefthand side of the board (looking from top/front), and running parallel to the front of the machine. Physically, PC 168-pin DIMMS can "almost fit", but the notches are just slightly in the wrong place - I have no idea if they are electrically compatible or not (I'd guess not - I tried this just for physical comparison only).

(use the R/W line to select even/odd words) Still have latency issues, but less likely to show bad bit combinations. Dave.

Z8000 parts question

by aek＠spies.com

If this is like my S8000 (model 30 I think) system, then yse, 1/4" cartridges, DC300s IIRC. I believe the format is 4 track QIC11. -- I don't think they had more than one kind of cart controller. Have you archived the tapes, or the eproms from your system? I know it's pointless to ask, since you don't have any way to copy them, but do you have the hardware manuals for any of the cards in the system other than the CPU (which I have scanned already)

I had several Nabu 1200's, a Canadian built machine which was also an 8086 with 512K of RAM - 4 serial ports. Also ran Microsoft XENIX. Actually, you could run CP/M 86, QNX (a Canadian nix-alike) or Xenix - Xenix was the only one of the three which required an optional external (to the CPU) memory management unit board. I still have 1/2 of a Nabu - the machine consisted of two parts, a DISK unit which held the hard drive, WD controller and an 80-track floppy drive, and the CPU unit which sat on top. I got one of my CPU units back, however the disk unit is remaining elusive. If you are interested, you can view the CPU unit (inside and out) at my web page (see sig).

OT: Surface mount

by jpl15＠panix.com

I used to be quite disdainful / semi-scared-of SMD tech - until I designed a project for work which needed to use it and Marvin Johnston kicked my butt into working with the stuff. In addition to all the other items - I use a fine-tipped Weller adjustable iron, and I bought a nice binocular low-power microscope to work under - my past-half-century eyes need a bit of help with the tiny parts. I also use Eagle Cad for design and layout - such a long way from the tape and cut days of Xacto knives and transfer letters. All in all, I enjoy it very much, the things I'm building are postage-stamp size, and a huge parts inventory can be kept in one small set of plastic bin drawers... Cheers John

That would help anyone that -like me- has a unibus-cpu with nothing else attached to it. If you have (?) the scematics of the RK611, how much work would it be to put this into a fpga-design and add connect this to a (better four) CF-card socket(s) Then a cheap 32mb CF card would become a RK07+ media... If you follow the RK611-design, there is no bothering about driver issues, just a patch to the block-count to get those extra 4 megs of a 32m CF-card. A project like this would be a perfect entry for the VCFE of next year, isn't it? (Hurry up, only 50 weeks left! :-)) ) Greetings, Frank

IDEA - Collector interest database

by wacarder＠usit.net

Has anyone on here ever thought about putting up a site that documents the collector interest or areas of specialty for the folks who visit here? If this sounds like a good idea, I'll create a site and host it. It could have things like a "wish list", "current inventory", "items for trade/sale", etc. I know some of this type of thing exists elsewhere, such as on Sellam's VCM site, but I haven't seen a place where I can go to find individuals who have specific computers, parts, wants, etc. Other ideas and opinions are welcome. If this kind of thing already exists, just enlighten me as to where it is located. Ashley

Need Info On an Old 386 Motherboard

by gsutton9503＠wavecable.com

I'm looking for a manual and other info on this old 386 motherboard that I am trying to build into a working DOS 6.22/WfW 3.11 system for playing old games and to play around with DOS TCP/IP networking. The board, according to the BIOS string, is from Wintac-Edom (The BIOS string is: E0X3-1379-083090-K0 Beyond that, I can't seem to find any other info on this, as there are no other identifying markings that I can find. Here's a pic of the board... http://webpages.charter.net/scarletdown/Geekworks/GKW-Edom-MB-0.JPG Anyway, I currently have it set up with a VGA card, a 16-bit MIO card, Adaptec AHA 1542CF SCSI adapter, Databook PCMCIA card reader, PnP Soundblaster, 3Com EtherLink III 3c509 NIC, SCSI CD-ROM drive, 210MB Hard drive as the master drive, 1.5GB hard drive set as slave (will put EZ-BIOS on it shortly to make it useable on this old board), 386/DX-25 (or 33, I don't remember at the moment which) CPU, and 8MB of RAM in the form of 8 1MB 30 Pin SIMMs). So, when I boot up, she goes through the memory test, then the SCSI card does its self-test. After that, I get an error about the hard drive (this is because I haven't set either drive up yet), and am given the option to hit F1 to go to setup. Well, when I go into BIOS setup, everything freezes on me, no response at all from the keyboard, and all I can do is hit reset or power down. Odd thing is, though; I can boot up with a DOS floppy and access the C drive just fine, though the D drive is not yet visible of course. What would be causing this freezeup when I go to BIOS setup? And, where can I find a manual for this board? Thanks

Need Help On a PDP 11/60

by g-wright＠att.net

Hi Everyone I have some (3) PDP 11/60's that I'm trying to get running. I did manage to get all of the Power supplies going, removed all of the cards and cleaned them. check the cable routing and power supply voltages. I have got the LA-01 and TE-10's running. These systems have been setting since 1986. I do have All zeros in the console display. No other console lights come on ???? . no responce from any keyed input. The Memory cards all have power LEDS turned on (m7984 Mos) The Memory controller has a LED but it's off ?? (M7983) These are from a large test system and each has 5 to 6 cabinets. So in time I want to trim these down to the Base double wide corp. cabinet only. It looks like the board label on top of each card cage matches the cards. I believe the grant cards are all there where needed. Most of the slots in the 2 main card cages are full. The memory back plane does not have grant cards in the open slots and from the manuals I have, this looks correct ?? The question for now is what do the LEDs on the M7878 (11/60 status card, all on) and M7872 (11/60 micro word card, all but the top 3 are on) stand for or tell you. I do not have any manuals on the cards and a quick search did not turn up much. I posted this yesterday and it did not show up so this is a second post. so if you see 2 of these you know why. Yes, I might need help with my power bill also. Thanks, Jerry Jerry Wright JLC inc g-wright(a)worldnet.att.net

I found this little gem while excavating in the back warehouse of an electronics surplus company while on vacation recently. I'm guessing that it's pretty rare. Lots of blinky-lights and toggle switches! It looks like it's almost brand new. Now I just have to dig up my 4004 CPU and build something around it so I can try this thing out. Anybody have any information about it? The closest I came was http://www.rdrop.com/~jimw/j-boards.shtml, about the 5th entry up from the very bottom.

finds from TRW Swapmeet (AKA Northrup Grumman swap meet) today

by rwhulvey＠broadcom.com

Very interesting to see RH32 in the swap meet. I worked some on verification boards for RH32 in '93 and again in '95. Sounds like the board you have was made after I left in '95, since it includes Orca FPGAs which I don't think came about until after that time. We mostly used Actel FPGAs when I was there. It was a fault-tolerant design which was supposed to detect a fault, then back up and start re-executing code prior to the fault. The boards I worked on had only 1 CPU chip, 2 MMUs (for for instructions (IMMU) and 1 for operands (OMMU)), and a connector for an SCU (I forget what that was ... system control unit?) daughtercard, as well as an FPU (floating point unit) daughtercard. I think it was designed to support multiprocessor configs, but we only tested single-processor, as we were bringing it up for the 1st time. As I recall, RH32 was started around '88, supposed to complete around '91, but was about 2 years late in '93 when I started working there. I think it was finally announced in '98: http://www.findarticles.com/cf_dls/m0EKF/n2232_v44/21034857/p1/article.jhtml There were also efforts by IBM to make silicon-on-saphire versions of their RISC System 6000 CPUs which supposedly did not need the explicit hardware fault tolerance used in RH32, since the process was inherently resistant to radiation induced faults. I don't know if it was ever shown to work well. Seems to be a lot of info on the 'net about compiling code for RH32, and even references to it in source files. I guess they ported Linux to the thing long after I had left. I recall TRW contracted Green Hills Software to make tools for it. -Rob Hulvey

Apple mouse

by mtapley＠swri.edu

My 512K Mac has the squarer connector (although the Mac itself has been upgraded to a Plus). But I don't think it has the little Mouse icon on the connector - I'll have to check that.
