TDU, TDF and "Doing magtape image archiving" [was: HP 7980S ...]

by Fred.van.Kempen＠microwalt.nl

All, Oooh... hrrm. Didn't realize there was such a lot of interest in those (already). The toolkit is basically an API in the shape of a C library, which handles all the nitty gritty of the TDF (Tape Distribution Format, aka Tape Dump Format) file format stuff. The user interface for reading physical tapes to image, writing the images back to physical tapes, and doing all sorts of weird stuff with the image files, is handled by a single program called TDU, the T... Utility. Its synopsis is similar to that of 'tar': -------------------------------------------------------- TDU version 1.0.15 for OpenBSD on VAX. Usage: tdu [-f file] [-m maxchunk] [-p path] [-v] cmd [args] where 'cmd' is one of {c|e|i|p|r|t|w|x} -------------------------------------------------------- Also, several conversion tools exist to convert between TDF and TAP (used in Ersatz-11 and SimH simlators) and raw formats. The tookit is currently in its final First Release testing, at version 1.0.15. It has been tested with the following systems: - DOS 6.22 and Win32 DOS box (with ASPI layers for tape I/O) - Windows 9X, NT 4.0 and 2K, Win32 console app - DEC Ultrix-32 V4.5 both VAX and MIPS - OpenBSD/vax V3.1 - DEC Ultrix-11 (on PD-11/83, both real and emulated) - SunOS 4.1.4 on SPARCstation - Solaris (cant memebr which one) - SGI IRIX Porting to VMS is being done by Robert Alan Byer, of SimH/VMS fame. Thanks to Tim Shoppa for helping me out with one of those 'does this ever happen?' issues ... :) I have added TDF support to SimH, so you can just do a simh> mount mt0: /u/dist/rsx11mplus-4.2-tp1.tdf /wprotect /tdf in SinH and then boot the tape. The goal, of course, is to be able to easly get an archive of software up and running. Here's sample output of what an RSX-11M Plus V4.2 tape looks like: -------------------------------------------------------- (vaxlab)$ tdu tfv rsx11mplus-4.2-tp1.tdf TDF version : 1 CRC-32 : 0x32b466df Part # : BB-J083H-BC Serial Number : ME109856 Tape Label : RSX-11M-PLUS V4.2 MT:1600 Description : BRUSYS STANDALONE COPY SYSTEM Copyright : 1989 Owner : DIGITAL EQUIPMENT CORPORATION File 0 : blocksize 512 (439 blocks) File 1 : blocksize 80 (2 blocks) File 2 : blocksize 80 (1 blocks) 2 : blocksize 512 (2 blocks) 2 : blocksize 80 (1 blocks) 2 : blocksize 512 (1 blocks) 2 : blocksize 80 (2 blocks) 2 : blocksize 2560 (1 blocks) 2 : blocksize 80 (1 blocks) 2 : blocksize 4144 (28 blocks) 2 : blocksize 560 (1 blocks) File 3 : blocksize 80 (2 blocks) File 4 : blocksize 80 (2 blocks) File 5 : blocksize 80 (1 blocks) 5 : blocksize 512 (2 blocks) ....... -------------------------------------------------------- All I need to do is testing magtapes written with TDU, and I need the HP to work for that. The code will be released for more testing after I merge in Robert Byer's VMS stuff when he's done. Cheers, Fred

OT: Anybody have these Apple items??

by r_beaudry＠hotmail.com

Hello all, You knew this list would closely follow the free list :-) I believe all of these are too new to be on-topic, so my apologies... It never hurts to ask, right? If anyone has any of these items, please contact me OFF-LIST... Thanks! 1) Apple Localtalk Locking Connector Kit, DE-9 (for a LocalTalk PC Card). I have two cards, so I'd like two kits... 2) I recently purchased a 12" PCI-slot Apple PC Compatibility card, for a PowerMac 8500, but it did not have the three-connector monitor cable (one connects to the PC card, one to the monitor, and one to the Mac video output). 3) Apple "Superdrive" 1.44MB 3.5" floppy -- needs to be the AUTO-INJECT style, where the manual eject pinhole is directly to the right of the drive slot, and NOT where the pinhole is directly below the slot. You can also identify this drive as one WITHOUT the flap over the drive slot. The bare drive is fine, as I intend to put it in my own enclosure. I'd like to get two if possible. I guess that's it for now.. :-) Rich B. _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

HP 7980S scsi 9-track [GAIN]

by Fred.van.Kempen＠microwalt.nl

Hey all ! *grumpf* still not working. Although I can change the DENSITY setting with CONF 46, it doesn't "hold" it. The moment I try to write a tape, it switches back to the original 6250 setting. Meaning (apparently) that the host is forcing it to 6250... So... how does one tell that thing that host (SCSI) commands can **NOT** override the default density stored with CONF46 ? I grabbed the Sun manual, but that didn't say much about it, just that it had a DENSITY switch which mine doesn't have, and the info on the COFN46 stuff... --fred

SCSI drive available

by Fred.van.Kempen＠microwalt.nl

I used to have about half a zillion of these and other "anywhere between 2 and 9G" SCSI drives, mostly taken from old Compaq servers I had to service. Most of them have been given away, but I do have some 4GB's left. I *might* have a bunch of 9GB barracuda's left, too, which run at 7200. And get hot. :) --f

I truly wish I had the physical space to put up some racks with an 11/40, 11/34a and an 11/70 side-by-side -with- all the stuff that used to go with them... *sigh* --fred

Yeah :) I wrote my own ASPI layer for both DOS and Win32, and developed a bunch of tools around them to handle the reading, writing and archiving of tapes of various sorts. Kinda nice, because I can read in magtapes, store them in a single formatted file, enter the info on the tape label, and then let it sit on my server, or email it around. Later, one can re-write a tape using that file. The drawback is: many tapes [worldwide] have decided to gather up and move themselves to Holland, to find their eternal piece in archived format. In other words... gawd, I still have a PILE of tapes to go.... Anyway. The toolkit runs under most UNIXes, too, so no problems there. The 7980S is actually connected to a MicroVAX 3100 running Ultrix, and that box is my fast-tape-reader. Nice! It responds fine, no extra stuff needed. Cheers, Fred
