Sampsa, You can add area 42 - my log files can take it :) If polling machines that aren't always up is a problem, then BET:: is always up, and my main machine.

New attempt at HECNET PHONE directory

HECnet Instant Messenger - no longer pre-alpha code :)

I've had a bit of a play. Nice. We had a similar thing many years ago when i worked at the university. One of the students wrote it for a laugh. He had an Ultrix client for it too. My handle, by the way, is the utterly unimaginatve "tonyblews". Tony. On Fri, Jan 25, 2013 at 7:20 PM, <sampsa at mac.com> wrote: Oh yes, add me as well, my handle is 'djinn'.

Tape drive explosion

by ian＠platinum.net

It works! After much fooling around, I figured out what was going wrong. I hate to admit the largest of the problems, but I guess I should come clean... After writing and reading DLTIII tapes to make sure the hardware was working just fine, I moved over to using TK50 tapes to see if I could read them from Linux. No matter what I did, I was not getting a VMS-style tape. In fact, I was getting back the same data that I had written to the DLTIII tape for testing???? Was there some buffer somewhere? No, the machine I was testing from has a DLTIII tape drive installed internally, as well as the external tape library I was playing with. All my testing was actually being done to a tpe installed in the internal drive - I was using the wrong device name. Oh well, after wasting a few hours on that, I figured out the correct device name, and performed the tests again. Everything started working! I have now grabbed about 20 tapes and archived them. One tape got stuck in the drive, and a couple of tapes are coming up with read errors, but I am able to read a surprising number of them. I'm starting to post the tapes up on my archive page here: http://www.vaxhaven.com/index.php?title=TK50_Image_Archive You should start seeing more appear as the evening progresses. The images are in SIMH format, which is documented on the SIMH site. A better programmer than I should be able to write a VMS program to read SIMH tap files and write them to real tapes. This would close the loop. I'd appreciate feedback if anyone has the opportunity to test some of these images. Ian

Tape drive explosion

I am unable to find it anywhere, and I'm trying to decypher the front panel controls for this device. I had a good search, I found everything but the user manual. Is there any chance of removing the tape drive deck from it? I thing the TZ875 (from the pictures) just has 5 drives in a 4U box at the back. It might be faster to extract a drive from it and use that! If you do it carefully you can put it back afterwards. :) I can read and write DLTIII tapes without a problem. Reading TK50 tapes seems to work, but I'm getting random garbage. There appears to be a method to override the density on the front panel, but I can't quite figure it out. The individual drives have 2 buttons, one unloads the cartridge, the other selects the density of the media manually. Obviously, on a jukebox this will all be connected to a micro-controller that does it via the panel, which you don't have am manual for. If it were me I'd just futz with the panel (with no tapes in) and see if there was a density override option but I'm *guessing* you tried that. -- Mark Benson http://DECtec.info Twitter: @DECtecInfo HECnet: STAR69::MARK Online Resource & Mailing List for DEC Enthusiasts.

I have never seen a TK70 drive with another interface than the QBUS controller TQK70 or the BI bus controller TBK70. The two generation of DLT drives after TK70 has had either SCSI or DSSI interfaces e.g. TZ85/TF85, TZ86/TF86. Then the DSSI interface was abandoned and all the rest of the DEC branded DLT drives had a SCSI interface only i.e. TZ87, TZ88, TZ89, TZ90. I don't know why the DSSI interface was dropped, but I guess the SCSI drives sold better especially to the Alpha customers.

Its outer end which grabs the tape from the cassette is arrow-shaped. Is the "arrow" quite in order? If not, the takeup leader should be replaced. Tape leader is fine on this drive. The problem with this cartridge is the spool inside the cartridge jammed and wouldn't rotate causing the drive to not rewind. Ok. Cartridge failure, then. Could it have been accidentally dropped? I've seen several times DLT cartriges fail after been dropped on the floor. You can also read a TK50 tape with a newer DLT drive like TZ85, TZ86 and TZ87. Is this true? According to Wikipedia http://en.wikipedia.org/wiki/Digital_Linear_Tape a CompacTape I can only be read by a TK50 and a TK70. Can anyone confirm or deny this? I have some newer generation DLT drives, but none of them admit to being backwards compatible that far. Ian . I'm not sure if others than DEC branded DLT drives (TZ85,TZ86,TZ87) can read TK50 tapes, but DEC drives sure do. Even the front of the drive has leds which indicate which formats the drive can handle. Like Johnny said, Wikipedia articles aren't always the complete truth of the topic.
