Does anyone have an image of the Fortran DECtape which is compatible with RT-11 v2C? I have a copy which is labeled as being suitable for RT-11 v2C, but it does not have the 'fortra.sav' file. There is a 'forgen.com' file. Since RT-11 v2C doesn't support command files, I don't think the tape is for RT-11 v2C. Thanks! --barrym

Can anyone ID this machine?

by alexeyt＠freeshell.org

A coworker of mine showed me this link. Whatever it is looks pretty sweet, but I don't think I've ever seen a similar machine. Anyone know what it is? Is it even a computer, or some sort of teletype switching office? http://i.imgur.com/tDA3X.jpg Alexey

WANTED: More regional collectors

by tosteve＠yahoo.com

Hi, I run the website http://oldcomputers.net I get a lot of old computer systems offered to me for cheap or free, but most I don't want - too big, or too far away to pay shipping. A while back I asked for other collectors who would be receptive to these orphaned systems, and over 60 people have signed-up so far! But entire parts of the US are still open - the East coast is covered pretty well, but west of the Mississippi River these is almost no one until the coast. I've got Nathan in Iowa, Richard in SLC, but that's about it. Send me your name, email, and what you collect, and I'll try to get you some good stuff (some people got some REALLY good stuff). Thanks- Steven Stengel http://oldcomputers.net

Macintosh Programmers' Workshop - Fwd: MPW turns 25!

by toby＠telegraphics.com.au

Some ccmp listers will have fond memories of MPW. I know I do. Still runnable on my PPC G4! (OS X 10.4) & I still occasionally need to build with it. --Toby -------- Original Message -------- Subject: MPW turns 25!

VT fixums

by wdonzelli＠gmail.com

Just a reminder - this Saturday, just a few days away, RCS will be doing triage on our big pile of VT100s and VT100oids. We need the space! Incoming Cray! Failed VTs will be available for pickup at our open house in Providence, RI (see rcsri.org for directions). I may be able to move a few to the MIT Flea on Sunday. And of course, cash donations are very much appreciated, but not required. But appreciated. Really appreciated... -- Will

TRS-80 Model II Digging

by nathan＠nathanpralle.com

Finally pulled out the TRS-80 Model II tonight with the intention of actually working on it for once (shocker!) and trying to get it operational. It powers up, drive spins, screen comes on, lights glow, etc. Insert any one of about 20 8" floppies that I have that are specifically for the Model Ii and..... Nothing. Well. BOOT ERROR RS, which is translated as, "Disk not in RadioShack format." I'd believe it for one or two, but all of them? It seems unlikely, although I could blame bit-rot perhaps. I'm hoping it has something to do with the hardware instead. Popping it open, the unit powers on and the drive head is dropped to the spinning disk, then lifted, then dropped, then lifted, and the error occurs. I cannot see if the head is close enough to the disk or not (and I have *no* idea of the tolerances anyway) and am not sure how I'd adjust it -- or drive speed, etc. if that's an issue. So, anyone got ideas? There *is* a remote possibility that all the disks I got were wiped either by the previous owner or in some sort of magnetic disaster, but they're well-labeled and came from a working haul, so I have to imagine that they're still good. Or at least, I'm hoping they are. (The bits are damned near visible on these things, after all.) Your ideas and good guesses welcome and very much appreciated. Nathan -- *Nathan E.

TI CD 1400 Drive [for sale / offers]

by rborsuk＠gmail.com

I need to get rid of this drive. I don't have the TI990 computer for it anymore. If I don't get any offers in the next couple of days I'm going to scrap it out (that said - this is not free). It's a TI CD 1400 branded drive. Magnetic Peripherals 944B drive. The unit weighs 175 pounds so it puts out of the standard shipping range. Please send any offers off list. Drive is located in Port Huron, Michigan. Rob pics at http://tinyurl.com/3hdv62b

cctalk Digest, Vol 97, Issue 5

by ceby2＠csc.com

Rich, >> You could force an 8 bit boundary on the resulting data, but things >> like sector headers are sometimes deliberately encoded in >> fluctuation sequences that don't conform to rest the data encoding. >That's hardly deterministic, and would certainly not work on, for >example, a disk written by a PDP-10 (36 bit words represented as pairs >of 18 bits + parity), to take a popular example. There *are* no >deterministic outcomes, especially in archival work. There is only >interpretation. Precisely, yes. But even with byte encoding of bitstreams you have an endian problem. At some point the capture system imposes its personality on the process and you simply have document what you've done so the upstream ('viewer'/'accessor') toolset can take it into account in post processing. The adding of metadata context is what contributes to the deterministic outcome, rather than attempting to force raw capture into a rigid format. >http://www.boogles.com/local/papers/tcfs-thesis/thesis.html >This is Brian Zuzga's 1995 undergraduate thesis at MIT on a project to >archive the backups done at the MIT AI Lab using what they named "the >Time Capsule File System". Nihil novi sub sole (Ecc. 1:9-10). Thanks for the reference. I must have come across it before at some point as it seems very familiar. But it wasn't a work I was referencing yet in preparation. I'm studying it closely, along with things like the UPF. What strikes me is how there are several originating documents around effort followed by long silences and lack of back references. It may be down to the relatively cursory nature of my work so far, but it seems adoption of these formats and processes has been either quiet or limited. Is that a misapprehension on my part? Any other efforts you think I should investigate? -- Colin

Old printer tricks, HP LaserJet 6P

by vintagecoder＠aol.com

I received an old HP LaserJet 6P. According to the doc it has an IEEE-1284 interface (B and C ports). The PCs I have don't have parallel ports. Will a USB to parallel converter cable "just work" or how should I hook this up to a Windows XP box? Also, any comments on this unit? I remember seeing some threads with people praising/damnning various HP models. Thanks.
