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.

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

Fax (was Re: Nine technologies that have faded into history)

I don't recall the exact wording, but basically any setup that scans a physical document, transfers a representation over a telecommunication system, and recreates it as s physical document again meets the US legal definition of facsimile. There doesn't have to be a "fax machine" as you would normally consider it, and Internet email should qualify for the telecommunication, but if the document doesn't start and end in physical form, it isn't a fax. In other words, if I sign a paper contract, scan it, email it to someone, and they print it, it has been faxed. But if I start with a PDF file, sign it in a graphics program, and email that, it has not been faxed because it did not originate as a physical document. If the PDF was originally a scan of a paper document, but I fill it in digitally, then email it, that's not a fax because the electronic document is not an accurate, unaltered representation of a physical document. [I'm not a lawyer, so take this with a suitably large grain of salt.]
