My wildly subjective, overly general observations: 1) When a big fish is caught, it's usually an "I took a bunch of doco I shouldn't have to my next job" situation. I've discussed more nefarious high-level mole scenarios with the FBI numerous times. It happens, but it's not apparently that common. 2) When a little fish is caught, it's usually some variation on "I'll teach them". And as Mouse notes, effort is usually made not to publicize the event unless there's a regulatory driver that requires it. That said, there's a *huge* amount of little fish "espionage" that flies under the radar. Things like client lists, marketing plans and confidential designs quietly walk out the door all the time and are rarely noticed. With these sorts of things, it's fiendishly difficult to assess the impact on the victims business. 3) No one is particularly good at covering their tracks (including people who in theory know how to do it). Unfortunately, the tools to proactively spot data exfiltration are rarely implemented and even more rarely implemented well. BTW...that's more an function of how difficult the problem is rather than an indictment of the practitioners. KJ

Ferroresonant transformers and 3278

by tmfdmike＠gmail.com

I recently blew up a 3278... it worked ok for a few hours then started blowing fuses. I haven't done any troubleshooting yet but checking the manuals on Bitsavers tells me my US 3278s have ferroresonant transformers specified as 120V 60Hz only. This can be expected to cause problems with 120V 50Hz here in NZ from my knowledge of how ferroresonant transformers work; I'll get excessive magnetic currents - overheating - all kinds of nasties. I can wind the voltage down a bit and run them at 90-100V but that doesn't help much. 1. Does anyone in a 50Hz country have any dead/spare 3278s and/or transformers for them? The IBM part number for the 50Hz 220V are 8715343 or 4119686. 2. I have other equipment where this will be an issue and not so easily solved. Does anyone have any experience in or recommendations for frequency conversion equipment? My System/3s for instance all use 60Hz ferroresonants operating off 208V 3-phase - now voltage can probably be retapped or easily converted but I still need to make a lot of 60Hz to run them... Thanks Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother. Not for millions, not for glory, not for fame.

Old versions of 2.11BSD

by dugo＠xs4all.nl

Over at TUHS an attempt to put the history of 2.11BSD under version control (git) stranded somewhat. After some digging the patchlevels that can be found in the archives are now 195, 277, 303 and 431. The base 2.11BSD is sorely missing. The numbered updates by Steven M. Schultz are not pure context diffs. eg. an attempt to reverse them breaks where ld.c is removed in update #160 and can't be pieced back together accurately using 2.10xBSD and assorted patches. Maybe someone here who missed the thread on the TUHS mailing list has a really old copy of 2.11BSD lying around? /Jacob

The KGB, the Computer, and Me

by rodsmallwood52＠btinternet.com

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. Just on doing a search, the usual > 1,000,000 items stop being anything at all relevant after item 100. google is often good to check spelling though (LOL) - I can't spell, so I always use the Spell checker.

Also SSP V1.3 (Scientific Subroutines Package) and LSP V1.2 (Laboratory Subroutines Package) would be great to find as well. These all run under RT-11 and I understand that there was also a version (V1.1) of FEP and V1.0 of FRP that ran under RSX11M which would be fantastic to find as I am more interested in RSX11M.

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

by useddec＠gmail.com

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
