In fact, I have several complete PDP-8/I systems with EAE and DECtape that are being surplused and which are looking for a good home. Also, a small stock of DECtapes with miscellaneous OS/8, DECUS, and FOCAL software, as well as DEC publications such as Introduction to Programming and the OS/8 Handbook. I also have the complete set of DEC's PDP-8/I hardware diagnostics and associated documentation. Some of this stuff is in storage at the Lick Observatory facilities on the UC Santa Cruz campus.

Jones To: pdp8-lovers@ai.mit.edu Subject: PDP-8/I I have located two PDP-8/I machines, one of which worked when last used in 1987, one of which is in unknown condition. The machines are mounted in third-party X-ray diffraction machines, and they share an auxiliary DEC cabinet that holds an Ampex 9-track tape drive and a DF 32 disk drive (32K words capacity). Both tape and disk also worked as of 1987. They share the peripherals through some kind of bus mux. Both machines are minimal systems, with only 4K of main memory. Be aware that the Ampex 9-track tape drive reads and writes tape in a distinctly odd format! As far as I understand it, it reads or writes a pair of 8 bit bytes for each 12 bit word transferred to or from tape, in 8-4 format. It can write 9-track tapes that others can read, but it may not be able to read arbitrary data from such tapes! The owner (who has previously disposed of a straight 8 to someone in Indiana, he forgets the name) would prefer to find a good home for them instead of junking them, since unless he can line up a buyer beforehand, the best our surplus operation could get for these machines is around $10 for the CPU and perhaps $25 for the tape drive to someone who doesn't suspect it's odd 12 bit wiring. I'll put anyone who's seriously interested in these antiques in contact with their current owner, since they don't fit into any of my PDP-8 restoration plans. If you're worried about physically getting them, they're in Iowa City, on I-80 an hour east of the Mississippi River. Be careful moving that disk, by the way, it's one of the oldest (and smallest) disks I know of that may still be in good working condition.

If so, the interface to the magtape may be a wierd one. The one that I used could only transfer the low order 8-bits of a word and the data could only be in Field 0. High order bits were ignored on read and on write. Why would anyone bother to wire up the support for specifing the DMA Field in an IOT, anyways... I have a driver for the magtape for the 4K Disk Monitor System. It does require the use of the Field 1 swap area for the compose/decompose of the data so you have to have at least an 8K machine, in which case, why aren't you using OS/8? :-) The driver simulates a 1024 block DECtape (supported of course by the 4K DMS). To do this it uses a tape format that is BOT long gap EOF two's complement block number (0000) long gap EOF 128 bytes 128 bytes long gap EOF two's complement block number (7777) long gap EOF 128 bytes 128 bytes long gap EOF two's complement block number (7776) long gap EOF 128 bytes 128 bytes ... The key to rewriting records in the middle of the tape is the long gap stuff. I also have the formatter that produces the tapes above, and a dump-restore program for DF-32 to tape. These will be of great use to the myriad of happy programmers still using the 4K-DMS, PAL-D, and FOCAL-D. The driver is loaded from the dedicated driver area of the 4K-DMS and overlays the DECtape driver. It runs with interrupts enabled (as would be the case with the 4K-DMS), and is loaded as a paper-tape overlay during the installation of the 4K-DMS. I wrote it in the late 1960's. Since the TU-10 and TU-20 drives are so much better and can use core-dump, it is possible to write an OS/8 driver for both DECtape simulation and a more conventional sequential tape format. It was even possible to run an OS-8 system on magnetic tape only with no disk drive. S l o o o o w . . . If there is a great demand for this software should I put it somewhere for FTP access?
