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.

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.

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.

I am trying to collect everything I can get a hold off. I have a .LS for PAL12 but can't find my original .PA If anybody is looking for something, just let me know and I'll be happy to send whatever. I expect to get things on a VAX and save it on mag tape. Here at my work, we still use the '8'. Mostly it is used for small FORTRAN jobs - graphics. We have good interactive graphics. It is very fast from the editor thru a running program using a silicon (RAM) disk. Wally Kalinowski 213 336-6940 work 515-1544 home
