How hard would be be for these SCSI to SD adapters to behave as if they were several drives, thereby giving you a chance to use all of that capacity? At those prices, though, it's hard to quibble.

Problems untarring on a UNIX PC (SysV)

by classiccmp＠philpem.me.uk

Hi folks, I'm trying to transfer some files from my PC to an AT&T UNIX PC. I've got Kermit up and running at 19200 Baud (after applying a kernel patch to increase the serial port poll rate) but the UNIX PC seems to be having trouble creating the directories from the tarball. On my Linux box I use this command inside kermit: CSEND {tar cf - file1 file2 ...} And on the UNIX PC: CRECEIVE {tar xf -} This works fine if I send files, but not directories: the UNIX PC's terminal is covered in messages like "CORE/diag/sys: cannot create". Does anyone know what I need to do to make GNU tar 1.26 produce a tar file the UNIX PC (some variant of SysV as I recall) can unpack? Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

BOUNTY: HP-UX 11i v1 TCOE

by doc＠vaxen.net

Yes, it's a bit off topic, but I've beat my brains out trying to get HP to even talk about providing media. We are licensed for HP-UX 11i v1 (11.11) TCOE on several C8000 PA-RISC boxes but we don't have install media. The original media kit p/n is B6821AA, and the C8000 requires Dec 2004 or later media to boot. Concurrent 11i v1 application media (p/n 5014-1459) would be nice, but not a necessity. This is for my employer, so it's not a freebie. Please contact me off-list if you can help. Doc

There's a far larger market for this than this mailing list. I don't know why more hardware hackers don't give away their designs. Let the far east build 'em for you. - John

A New Year and a large cleanup - 2

by quapla＠xs4all.nl

As the collection of stuff I'm letting go seems a bit too much for people to take in one go, I have divided the whole into lots. A lot will be marked 'reserved' only if it is a firm reservation. Lot's do not have to be collected immediately, if needed, it can be set aside for a few months. However, in such case, 10% of the accepted offer is required as a security. Stuff can be shipped, local pickup is preferred and the stuff is located in the Netherlands. The lot list can be found at www.groenenberg.net/download/1170/ Ed -- Dit is een HTML vrije email / This is an HTML free email. Zeg NEE tegen de 'slimme' meter.

I've found that in many of the programs on my PDP-8/E, even > parity is required, which I presume stems from the Model 33 ASR days. Eh? What? There was an option for 8-bit clean communication in the ASR33, as well as other parity choices. But by default an ASR33 have *MARK* parity. And all older PDP-8 software that I've ever seen also assumes MARK parity. If you try running older PDP-8 software with your terminal set to even parity, it will not work. If you are ever near an ASR33 with a paper punch, you can easily verify that it is doing mark parity by just enabling the punch, and check what codes you get there as you type, with the ASR33 in local mode.

Pentium I boards

But, other than replacing the CMOS battery, it ought to be OK. It is an Intel brand motherboard. Jon

I was thinking that RSX-11 backups would be readable by at least some versions of VMS. No. VMS BACKUP cannot read RSX BRU format savesets. But you can (could) run BRU on VMS... >> >RSTS Backup actually generates VMS save sets, the same format. > That's good to know. Right. Different PDP-11 OSes use different formats, so it's not really meaningful to ask about "PDP-11 backup". You need to specify which backup format you are talking about. I think I know of at least four. RSX used to use something called DSC (which stood for Disc Save and Compress), which was eventually replaced by BRU. I assume RSTS/E had some backup format in the older days. With RSTS/E V9 (I think it was), a new backup utility was created, which is the VMS compatible one. I'm not aware if RT-11 also had some backup tool, but I would assume so. Johnny
