Hi Anybody who has not seen this film (The KGB, the Computer, and Me) its worth a look. 1980's DEC systems everywhere, LSI terminals, HP kit, Tape drives in action and apart from the Mac no Windows anywhere. I think LBL must have bought one of everything. The story (true) is not bad either. I now expect to get a long list of weveseenits. Rod

I don't see much in the way of information at that site to get me to those floppy images. There might be other DEC and non-DEC PDP-11 images that are of interest. This site also has many DEC and non-DEC files for the PDP-11 http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/ I usually find that anything to do with google that is not totally obvious to usually be a pain.

This afternoon I was able to download them all and in RT11/Simh copy all the files to a large DU: type drive to both verify that the disk images downloaded correctly and to put everything in one convenient volume to load on a microSD card for the SCSI2SD transfer to a real PDP-11. I didn't notice any file names duplicating as I combined the contents of the floppies and if that the case there were 168 files on the RX01s and 64 files on the RX02s with a combined size of 3976 blocks. Browsing through the files I saw lots of great example code for a wide range of scientific routines!! Thanks again for taking the time to put the files out there. Thanks again!! Mark

Available: various PSION organizers, parts, and documentation from the mid-80s

by tosteve＠yahoo.com

I have boxes full of like-new PSION II organizers that I recently received from a US distributed. These aren't rare or valuable, but they are new in the box and seemingly never used. There are different models, with both 2 and 4 line displays, and different amounts of memory. I also have memory modules, cables, and development documentation. There's also a PSION module duplicactor. If any of this interests anyone, let me know. Also: 50 pounds of old PC parallel, serial, video cables, etc. You can see pictures here: http://www.oldcomputers.net/temp/

120V, 50HZ

If anyone is interested, I know where there are 3 or 4 unused PDP-8As that are 120/50. I ask about the configuration and am waiting for him to get back to me, but they seem to be 12 slot core boxes. Amazing the new 50 or so year stuff still out there. Paul

It would be great to get copies of those DEC and DECUS floppies! Almost all DECUS software include the sources and a good example of source code is worth many pages of references manuals. Please contact me directly and we can discuss how to transfer them. Several of those titles sound very interesting! The MINC systems are great hardware platforms, but I was very afraid that much of the software had been lost. This is very encouraging! Thanks!

As far as I can tell from the engineering drawings there is no difference in the back plane. I am hoping to wire the MINC-23 to Q22 in the future to be able to run RSX11M+ on it with the 11/73 and a decent amount of memory. As far as I can tell there MINC cards would not have a problem with the Q22 bus and the modification to the BDV11 is pretty easy. The MINC-11 I plan to keep as a RT-11 system but with the 11/23 CPU and 256 KB RAM.

Ian, As we discussed offline, I'll be very interested to see the titles of the RX02s that you have "in the basement". It would be great to get as many of these DEC and DECUS MINC related software packages together in one collection so it doesn't get lost forever.

That is one subversion higher (V2.2 vs V2.1) than the documentation I found so its probably one of the last releases. Please email me privately if you find the image. Thanks a bunch!! Mark

M9301-YB Bootstrap/Terminator ROM dumps / listings?

by jnc＠mercury.lcs.mit.edu

> From: Johnny Billquist bqt at update.uu.se > The per-device code are in separate PROMs that are used in both the > 9301 and 9312. Those are the ones with the device code as constants in > the beginning of memory space for the PROM, by the way. As I mentioned, the M9301-YA, at least, does not have this code. (See the listing.) Also, again on the M9301-YA, the various bootstraps, diagnostics, and console, are scattered through both banks (ditto), so one can't just replace a PROM or two to chance the supported devices; one would have to replace the entire set of 4 PROMs. > I hope you also are aware that both the M9301 and the M9312 have > different boot roms for some machines. I know that the 11/70 use > different roms with other tests than other PDP-11s, and I seem to > remember that one or two others do as well. (The 11/60 keeps popping up > in my brain...) I have yet to investigate the M9312's in depth, but I did know there are quite a few different versions of the M9301 (which amount to different ROMs: I know there are two different etch revisions of the card itself, but I think they are programming-wise identical). I don't know of any good list of the variants, but here are the versions I know of (device codes abbreviated to save typing): M9301-YA /04 and /34 OEM version; has basic diagnostics, console emulator, boots from various devices (RK, RP, TC, TM, DL, PC, TA, RX), supports auto-boot on power on, and also power-fail restart M9301-YB /04 and /34 end user version; has basic diagnostics, console emulator, boots from various devices (RK, RP, TC, TM, TA, RX, DL, PC, RJS, RJP, TJU), also power-fail restart M9301-YC /70 version; contains basic CPU, cache and memory diagnostics, boots from various devices (TM, TC, RK, RP, RK06, RJS, RJP, TJU, RX) M9301-YD All models; contains code to allow a terminal attached to the machine to be a terminal on some other line; also has boot code for RX and DDCMP M9301-YE All models; has basic diagnostics, console emulator; boots from low speed paper tape or DECnet; supports auto-boot on power on, and also power-fail restart M9301-YF All models (auto-start not available on /45, /50); has basic diagnostics, console emulator, boots from various devices (RK, RK06, RP, TC, TM, TA, RX, DL, PC, RJS, RJP, TJU) supports auto-boot on power on, and also power-fail restart M9301-YH /60 and /70 version; contains basic CPU, cache and memory diagnostics, boots from various devices (TM, TC, RK, RP, RK06, RJS, RJP, TJU, RX, PC) M9301-YH All models; has basic diagnostics, console emulator; boots from DECnet, and various devices (RX, TU, DL, DMC), also power-fail restart The -YA is the only one I have examined in detail.
