Australian collectors - any takers for 1 or more HP1000A?

by guerney＠uq.net.au

STRICTLY IF there are enough definite takers for HP1000A units being sold off by tender by the QLD DMR (see http://www.qits.net.au/hp1000/ ), then I am prepared to act as a Brisbane staging post. According to Frank McConnell (see thread "16 x HP1000 A-series systems") these machines are 1983-1988 vintage. And they will be heavy. I have communicated off-list already with Geoff Roberts - anyone else? Although the closing date for a bid is 14 May, I am leaving town for two weeks holiday on 8 May, so any bid from me will have to go in by fax this Friday at the latest. I certainly can not hang on to more than one of these myself, so I will only go ahead with a bid if I am sure that I will not be holding them for long or our of pocket for long. Really, I am offering just in case I can be of help here to people who want something less than the full lot, when they would otherwise go to the recyclers. The cost each will be 1/16th of the total bid plus freight from DMR to me, then freight from me to you. I would expect a successful bid to be in the range $100-$500 but suggestions welcome (such as what is the Australian scrap value of them?). Please reply ASAP. Phil Brisbane.

Fwd: Re: Possible equipment for NADCOMM (IBM 029 punch)

by cfandt＠netsync.net

Okay, here's a msg for you folks who want an IBM 029 card punch. It's available in Indianapolis. Please contact Joe Montano <jmontano(a)iquest.net> to obtain it. Act on it ASAP as his boss may get rid of it soon. And no, I didn't simply forward the msg to the list without first recalling exactly what the machine in question was (in ref. to that DECMATE embarassment to me a few days ago . . . :-\ ) I've USED this type machine so know there *may* be belts inside of it ;) I have asked Joe, thru NADCOMM, to give a bit more info. He sent a little trying to compare it to a Teletype model 28 which only a few of us on ClassicCmp know.

scanning in pages

by lemay＠cs.umn.edu

I've started trying to scan in some pdp8/e data sheets. Before I scan in more pages, i'd appreciate any comments on what little i've already scanned in (one scan of a pdp8/e that is obviously too big, and two pages of data on a CESI pdp-8 processor replacement board). I plan to scan in more of those CESI information sheets on boards that they made for use in the PDP8/e computer. Is this the best way to do this, or is there a better way? http://www-users.cs.umn.edu/~lemay/pdp8_cesi.html -Lawrence LeMay

Ok, we're cooking now. I've got Fortran IV running on my HT-11 system (with FIS support no less!) and compiled the DEMO.FOR program into DEMO.SAV. That was pretty neat, but now I'd like to get DECUS C running on this thing. I found DECUS C on Tim's web site (cool) but I suspect it won't run on V2.

16 x HP1000 A-series systems

No. Those are probably the 1000 M, E, and F-series and are basically 21MX processors with the "HP1000" name applied. The A-series are later models. A600s were introduced in 1983, A400s in 1987 or 1988. I think they're largely compatible (e.g. they share a lot of the same peripheral I/O cards with the older 2100-family machines, and I think the processor has largely the same instruction set) but they're mostly smaller and faster. > - just a few km from that stash of HP1000's, but they are way out of my > league.

RSX to RT-11 OBJ file format

by jhfine＠idirect.com

I would like some help. I have a very old version of ODT.OBJ from an RSX-11 system. I MUST use this same old version to reproduce an old executable file, but I want to LINK under RT-11. The other file is in a source MAC file which does not use any system calls, so I can use RT-11 to run MACRO.SAV and produce a FOO.OBJ >from the source file. BUT, the ODT.OBJ file has the RSX-11 file format for RSX-11 and I can't do the LINK under RT-11. Can anyone suggest a way to convert it to an RT-11 file format? NOTE: I am not asking about the file structure of the directory, but the actual file format of ODT.OBJ itself. I can attach ODT.OBJ as a file for anyone who might be able to send me back the other version? It is already on a floppy with an MS-DOS file structure and I just used PUTR to copy it the the RT-11 system, but can't do the LINK under RT-11 and I don't want to switch to RSX-11. Sincerely yours, Jerome Fine

Fun with degaussers

There must be some point when you are >lifting the demagnetizer away that the effects from the device are >beneficial. The "lift it slowly away and then turn off" is an important point. This makes sure that the media really is demagnetized. If you turn it off while near the media, you can leave the media in a highly magnetized state. That said, 12 (or even 6) is way too many errors for a floppy disk. Cleaning the heads, re-aligning, or buying new media (there are lots of places that still sell 8" floppies) may be the real solution. >while swirling? Are you sure its not just one of those, or a combination >of two that really make the disk better? Is this truly making the disk >better or did the disk drive become amused watching you do all this and >then just decide to work because you made it laugh? You can have fun with large degaussers. For those with analog watches that aren't prized too highly, you can do some really neat tricks, such as making the run 60 times too fast (i.e. an hour every 60 seconds) or even making them run backwards!

Fun with degaussers

by allisonp＠world.std.com

My experience as I still use them is BAD BLOCKS are bad news (media dying) or just a crunch from powering down with the disk in the drive. If the disk does not erase and format without bad blocks it's trash here. I use my CPM system to format 8" SD disks and failure is not common but in all cases where I've seen that the media was shedding and gumming the head so it's trash media and a head cleaning. IF your trying to salvage data from a dying disk then you apply different rules. Allison
