To: pdp8-lovers@MC.lcs.mit.edu Message-Id: <900212173237.19.D89.JOHNNY-BILLQUIST@AIDA.CSD.UU.SE> Hi. I need help to identify some hardware I have recieved. It is made by a company called ''Tennecomp Systems inc'' for the pdp8. The sub system consists of 7 flipchip cards, which is inserted in the Omnibus. It should be connected to some external equipment, but I don't have that, and don't have the faintest idea what is should be connected to. There are several connectors, which are marked. Here is a list of what I have found out by reading... Connectors: Display (Centronics conn.) Printer/Keyboard (Centronics conn.) Control panel (Centronics conn.) Tape control (Canon D-sub) Cards: Autoloader (has a stereoplug conn) Printer and keyboard interface Autochem control panel Autochem ADC and control interface Tape controller (3 cards) The tape controller is connected with a very special top end connector, apart from sitting on the bus. This top connector entirely covers the card, and is wire wrapped, and has a cover above the wrap. I am very confused about this. Appearently the thing should have a printer and a keyboard, as well as some kind of tape. What the display and control panel should be I don't know. The Autochem ADC and control interface has a large IC, which appears to be an A/D converter. Why the "Autoloader" has a stereo plug, I don't know... Apart from this, there is a small box, which is connected to the omnibus cards by some cables. This box contains the Centronics connectors, a buzzer, and a stereo plug connector (could be coupled with the Autoloader). Any suggestions, or, even better, some tech. material on this would be greately appreciated.

I have a picture (a few > years old, admittedly) that shows a bunch of KI's with scads of DECtape. As DIGEX, who knows more about these things than I do will be happy to attest, the key is "ran". Compuserve's machines run an operating system that _used to be_ tops-10, but has been hacked and modified beyond belief. They started out with KAs and KIs; I'm pretty sure I heard that there are no more KAs there. There may be some KIs left, but I would guess that the majority of what they have these days are KLs. They are probably the largest commercial user of DECsystem 10s (note the capitalization - it's DECsystem 10, DECSYSTEM 20...) left in the world. Maybe the largest that ever was. Anyway, as previously noted, KICKI, a machine at Stacken, the computer club at the Royal Institute of Technology in Stockholm, Sweden, is to my knowledge, the only TOPS-10 machine on the Internet today. It is a 3-processor KI-10 (usually running in a 2-processor configuration due to power considerations), which runs a version of TOPS that was hacked to allow symmetric multiprocessing (SMP), which is normally only available on KLs. Although KICKI is the only DEC-10 at the Royal Institute of Technology that's on the Internet, there are others there that you can connect to via the ANF-10 front ends. Try a "set host" to ODEN, NADJA, and AURORA. ODEN is a dual-processor KL, NADJA and AURORA are DECSYSTEM 2020s, running Tops-10. ---Rob  Received: from lcs.mit.edu (CHAOS 15044) by MC.LCS.MIT.EDU; 12 Dec 89 17:03:28 EST Received: from uxc.cso.uiuc.edu by mintaka.lcs.mit.edu id aa29888; 12 Dec 89 16:53 EST Received: from convex.UUCP by uxc.cso.uiuc.edu with UUCP (5.61+/IDA-1.2.8) id AA22926; Tue, 12 Dec 89 14:11:39 -0600 Received: by convex (5.51/4.7) id AA03263; Tue, 12 Dec 89 09:05:37 CST Received: by concave (5.51/7.0) id AA23544; Tue, 12 Dec 89 09:05:35 CST Received: from Version.6.23.N.CUILIB.3.44.SNAP.NOT.LINKED.concave.Unknown.Machine.Type via MS.5.5.concave.convex; Tue, 12 Dec 89 09:05:34 -0600 (CST) Message-Id: Date: Tue, 12 Dec 89 09:05:34 -0600 (CST) From: "Anthony A.

You could do it pretty blindly with an excellent chance of success IF you're good at removing DIPs from circuit boards. Since those were single-sided boards you'll have to be careful about the pads lifting, in which case simply clip all of the package leads (14/16) and then remove each separately. Install a low-profile socket (for next time ...). I've made many reparis and mods to 8/L's over the years by this method without any problems. Also, since the circuitry is so simple on a card, you can easily do fault analysis in single-step mode from the backplane (wire-wrap) alone -- no extender board is required and all you need is a level indicator (logic low/high) and a latch (did a pulse pass?). A nice environment to learn hardware repair ... The analog components (i.e. memory drivers and sensors) are another matter entirely ... paul  Received: from lcs.mit.edu (CHAOS 15044) by MC.LCS.MIT.EDU 25 Oct 89 14:05:06 EDT Received: from ai.ai.mit.edu by mintaka.lcs.mit.edu id aa11242; 25 Oct 89 13:58 EDT Date: Wed, 25 Oct 89 13:49:45 EDT From: "Robert E.

The easiest way is not to desolder the old chips at all. Just cut the pins close to the chip housing, then solder the replacement chips on these pins. Of course, you have to do this quickly. Also, you might need to cut the pins on the new chips short to prevent the chips to stick too much out depending on the space available between the boards. jaap  Received: from AI.AI.MIT.EDU (CHAOS 3130) by MC.LCS.MIT.EDU 2 Sep 89 05:17:28 EDT Date: Sat, 2 Sep 89 05:19:40 EDT From: "Robert E.

Many of you may already know me, but here goes: I have two PDP-8's; a PDP-8/f and a PDP-8/e. These are my "fun" systems; I also have two 2020's, one of which I use for real work and the other is spare. PANDA.PANDA.COM is the Internet name for my 2020; its an MX record so it's only accessible by mail. [Tomobiki-Cho.CAC.Washington.EDU is the NeXT on my desk at work.] The 8/f is a table top unit, works, and is completed filled. It's got: EAE, power fail restart, programmable real time clock, simple DECtape control, 12K core, and a TTY control that I modified to be 1200 baud EIA. It plugs in to one of the TTY ports on my 2020, and this is how I download the 8; I got all the papertape software into files on the 2020 just before I lost access to a paper tape reader. The 8/e is in a rack and doesn't work. From console examine/deposits, it seems to have bits stuck on and off (although the latter may be burned-out lights). Furthermore, its timing board doesn't work; it causes a trap to 0000 on IOTs (provided, of course, there's a board listening to that device number); it used to be the 8/f's timing board and I swapped it out. It has 8K of DEC core and some unknown quantity of what appears to be third-party memory. It also has a TU56 DECtape drive. I would like to get a useful system out of all of this. I've gotten quite bored with the paper tape software library that came with the 8/f. I have some DECtapes that are purportedly OS/8 but I haven't tested any of them out yet. What I think I want to do is get the TU56 out of the rack and have a table top system based on the 8/f. The rack is too unwieldy. I'd also like to salvage what is useful from the 8/e. The other possibility, if the 8/e's bus and console are OK (that I don't know, but I doubt it considering the stuck bits) is to use the 8/e. Then I could use all the memory I have (20K plus the third-party memory). I could also wire the 8/e's TTY board to respond to the paper-tape reader/punch and have a separate path for down/uploading. Any suggestions? Does anyone act as a clearinghouse for PDP-8 parts, e.g. will take parts that aren't needed off people's hands and supply them to people who do need them? I'd be a lot more willing to give up the stuff I don't need from the 8/e if I knew I could get some board I need for my 8/f in the future... -- Mark -- -------  Date: Fri, 4 Aug 89 14:12:46 EDT From: PDP8-Lovers-Request Subject: [jmbaldwi: I've got a pdp8 that I'd like to use.] To: PDP8-LOVERS%MC.LCS.MIT.EDU@MINTAKA.LCS.MIT.EDU Message-ID: <604221.890804.PDP8@MC.LCS.MIT.EDU> J.M.

When I was in college ('72 - '76) it was considered highly cool to be able to bring down the 32K timesharing PDP-8/I running TSS/8 and bring up PS/8 and have all that raw power to yourself. OS/8 was just coming out then, if I remember, and it was considered PS/8's successor. Unfortunately I didn't use it enough to remember much about it now, but I remember we were impressed that it had "device-independent i/o"; TSS/8 programs had to read and write to specific devices; e.g. to compile a program on a dectape you had to first run COPY to get it onto the disk. (To get it from a paper tape, you had to run a different utility, PIP!) With PS/8, this historical curiosity went away.

When Dec made the RL01, they left room for possible expansion (then the masses got the 02). To tell you the truth, the Rl02 is just a RL01 with 2X the tracks. As far as software goes, that's another story. You would have to hack the OS/8 driver to be able to access those extra sectors. Check the sourcecode. You might have to only change a few things (like #tracks). Once the driver is patched, the rest should go smoothly.

Date: Wednesday, 20 August 1986 03:42-EDT From: Mark Crispin To: TOPS-20@SU-SCORE.ARPA, Boken@RED.RUTGERS.EDU Re: DEC's PDP's Postal-Address: 1802 Hackett Ave.; Mountain View, CA 94043-4431 Phone: +1 (415) 968-1052 A number of people have requested my list of all the DEC PDP's, so I thought I'd bore you all with it. The PDP-1 was an 18 bit machine. It was DEC's first computer, and some of the first timesharing systems were designed for it. It's also unique in being one's complement; all later DEC computers were two's complement. Some machines, such as one of MIT's PDP-1s, were in operation until the late '70s. The PDP-2 was a designation reserved for a 24 bit machine, but as far as I can tell it was never even designed and definitely none were ever built. The PDP-3 was a 36 bit machine that was designed but never built by DEC. However, Scientific Engineering Institute built one in 1960. The PDP-4 was an 18 bit machine that was intended to be a cheaper, slower alternative to the PDP-1. It was so slow that it didn't sell well, although it was interesting for its auto-incrementing memory registers. It was not program-compatible with the PDP-1, but its instruction set was the basis of DEC's future 18 bit computers. The PDP-5 was a 12 bit machine designed to be a small laboratory system. It used many of the ideas in the LINC (Laboratory Instruction Computer, designed by Lincoln Labs at MIT, some of which were built by DEC). The PDP-6 was a 36 bit machine and the first machine to implement the most wonderful computer architecture known to man. It was rather expensive and difficult to maintain, and not many were sold. As a result, DEC cancelled 36 bit computers for what was to be the first of many times. The PDP-7 was an 18 bit machine and the sucessor to the PDP-4. It was a major price/performance win over the PDP-4 and the first DEC computer to use wire-wrapping. The PDP-8 was a 12 bit machine and the sucessor to the PDP-8. It basically defined the term "minicomputer", and went through several incarnations. The original PDP-8 was followed by the extremely slow PDP-8/S (as bad as the PDP-4 was to the PDP-1, but at least the /S was program-compatible). DEC recouped with the PDP-8/I (using MSI integrated circuits) and the smaller PDP-8/L, and somewhat later came out with the "Omnibus 8" machines -- the PDP-8/E, the PDP-8/F (a half-sized version of the PDP-8/E), the PDP-8/M (an OEM version of the PDP-8/F), and the final machine, the single board PDP-8/A. The PDP-8/A still exists after a fashion as a current DEC product. The PDP-9 was an 18 bit machine and the sucessor to the PDP-7. It had a faster memory than the PDP-7 and was the first microprogrammed DEC computer. Modulo a 300 wire(!) ECO required in the first machines, the PDP-9 was a reliable machine and some are still in operation today. There was a short-lived PDP-9/L. The PDP-10 was a 36 bit machine and the sucessor to the PDP-6. It is especially noted for its software, which represents the pinnacle of DEC software engineering and has never been equalled. The first KA10, largely installed in universities, created a whole generation of timesharing hackers. The follow-on KI10, with paging and using IC's instead of discrete components but otherwise unexciting, mostly was sold to commercial organizations. The KL10 went through several incarnations and is today the most representative of this marvelous machine. The KS10 was a small, low-speed (approximately KA10 performance) processor which was DEC's last successful implementation of this architecture. The PDP-11 was a 16-bit machine that went through more implementations and operating systems than can be counted. Presently it superceded the less powerful PDP-8 as the representative minicomputer. While the PDP-11 used octal, it was in its deep heart of hearts a hexidecimal machine, and the first indicator of the creeping IBMification of DEC that took full fruit in the VAX. [I can hear the flames now...] Rather than fight it the customers loved it; more PDP-11's have been sold than any other DEC computer (possibly more than all the others combined). The PDP-12 was a 12 bit machine and the sucessor to the PDP-8. It combined a LINC and a PDP-8 type processor in the same box and basically was a new model of the LINC-8 which was the same thing. No PDP-13 was ever designed or built. Even DEC gets superstitious. The PDP-14 was a 12 bit machine with a 1 bit register. It was used as a process control engine in applications that were felt to be too rugged for a PDP-8, and basically replaced a set of relays. Later DEC made PDP-8's suitable for this sort of thing, but it didn't stop them from the ultimate silliness of building a PDP-14 that used a PDP-8 as its console processor! The PDP-15 was an 18 bit machine and the final one of this design built by DEC. More PDP-15's were built and sold than any of the others, and it went through several incarnations including some which used a PDP-11 as a front end. Apparently the cancellation of the PDP-15 came as a great surprise to the "Tiger Team" who worked on it, although considering its general ungainliness compared to comparable performance PDP-11's it wasn't surprising. In many ways the PDP-15 died for the same reason the PDP-10 did. The PDP-16 was a "roll your own" 16 bit machine based on various "building blocks". Every PDP-16 was essentially custom-designed by the customer. It got a fair amount of attention when it was announced but evidentally didn't sell very well. There was no PDP-17 or any other designator. DEC apparently decided that "PDP" had a perjorative ring to it.

Most are assembly time options, those that are not are marked permanent. 1) '.ZERO SYS:' or 'ZERO DSK:' are not allowed. 2) If the system date is bad, a correct one is requested and must be entered before a command line is processed. 3) '.RECALL' displays the contents of all remembrance areas. '.RECALL NAME' displays the contents of the remembrance area used by the NAME command. 4) CCLX does not forget remembrances when the date changes (permanent). 5) '.COMMANDS' displays all CCLX command keywords. 6) '.EJECT' sends a form feed and carriage return to device 66 (the standard lineprinter device number). 7) As documented, but not always done, in CCL, '.EDIT' remembers only up to the backarrow (permanent). 8) '.TOMMOROW' and '.YESTERDAY' increment and decrement the date. 9) '.TIDY' deletes all .TM and .WS files on the indicated device. 10) '.DEFINE NAME' adds a command 'NAME' which, when invoked, does a command decode iSV. 26) One letter is sufficient to specify several comon commands. 27) '.SQUISH' sets /O (does not ask "ARE YOU SURE?"). 28) '.FLIST' calls revised FLIST.SV. 29) '.FORMAT' calls ACID.SV or RUNOFF.SV depending on the input file extension. A '-NO' switch analogous to the '-NB' switch is allowed. 30) The remembrance code now allows up to fifteen areas of (assembly-time) variable size (permanent). 31) '-R' switch causes CCLX to not store the containing command line in its remembrance area. 32) '.PIP' calls PIP.SV. 33) '.FIX NAME /X' adds /X to the default switch options set every time '.NAME' is invoked. Backslashes similarly unset switches. Several switches can be fixed at a time, and several commands. 34) '.BOOT XX' (with space instead of slash as separator) inserts /. 35) '.FILL MYFILE.TX[139]' adds a file 139(10) blocks long to the directory of the specified device with PIP (no more than 255 blocks). 36) '.DUP RXA1:' without an output device forces /R (verify) option. 37) '.DSK DEVICE' calls DIRECT.SV exactly like '.DIRECT', but does not use a remembrance area. Consequently, '.DSK' defaults to DSK:, not the remembrance. / /Version 05.03 SECT8 IAND JA START ENTRY IOR ENTRY IXOR /TRAP3 RETURN RETRN=.+1 EXTERN #RETRN ADDR #RETRN /FIRST OPERAND FOR AND, OR, XOR /(SECOND IN FLAC) A, ORG .+3 / / PROGRAM TO TEST IAND / / I=262155 / J=262154+131072+65536+32768+16384+8192+4096+2048+1024+ / $ 512+256+128+64+32+16+8+4+2+1 / J=262154 / K=IAND(I,J) / WRITE(0,400) K /400 FORMAT(' K=',D15.8) !

Some efforts have been made to replace the cross-country Arpanet functions by tying various local-area nets together; such connections do exist for MIT. However, we can't guarantee how well this will work initially; we expect the new connection system to require some time to undergo shakedown, and mail service will probably go haywire during this period.
