A good overview of disc formats can be found in two National app notes http://www.national.com/apnotes/Others__v17.html AN-413 AN-501 describes the SMD interface, but National doesn't have it on line any more. It can be found at: http://manuales.elo.utfsm.cl/datasheet/national/pdf/nsc04334.pdf There are lots of other related app notes there related to using their disc chipsets which would be handy as well

Byte Magazine article on IO Selectric interfacing

by brian＠quarterbyte.com

Hi, Does anyone have the June 1977 issue of Byte Magazine (vol 2 issue 6)? There are two articles in there that I'd like to get a scan or copy of: "Interfacing the IBM Selectric Keyboard Printer" and "A 6800 Selectric IO Printer Program". If anyone has this issue and can scan or copy and mail the articles, I'd really appreciate it. Contact me on- or off list. Thanks, Brian

Needing info on error messages for "option board"

by rich＠sias.us

I am trying to get Central Point software's Deluxe option board to work on reading and writing tracks on floppies. It has been 10 years since I wanted to do this. I have version 5.4 and the book only has a little info on errors. When TCM copies from the one track and "R" is for read then it is to qualify the track read, "Q", I can do this to hard disk. When I do this >from the temp copy on hard disk to another floppy it does not come back "Q" but "2" or once "3" and message box had message about destination directory. I think there was an error writing to floppy but I can't be sure. I tried all 4 port postitions for the 2 jumpers. Anyone out there still familliar with the "Deluxe Option Board" and all of its errors etc. I may have more questions. All the 'good' stuff I was looking for aparently is in archives of this discussion group that is presently unavailble. 1997-1999 era. Rich Sias

Copy of STD39 Internet Standard (BBN Report 1822)

by spedraja＠ono.com

> It is on my list of things to look for. > BBN 1822 describes the host to IMP protocol > > I'm hoping there is a copy in the SRI archives at the Computer > History Museum. Good luck. I only located something remotely similar to one copy, but in one unreadable format, in: ftp.univ-angers.fr/pub2/rfc/rfc/std/std39.txt.gz This file is 3.3k long, instead of the 187 bytes of the official STD39.txt The rest of documents involved in the creation of ARPANET are availables in more or less form in diverse websites. I made one recollection of links if someone is interested. My interest in all these items is diverse. Like a History Student with the focus put in Contemporary History. Same about an important lack of Classic Computing information in our country (Spain) even in Public, Private and Universitary libraries. And finally, with the intention to recreate a simulated Network of IMPs, beginning with the four first installed. It would be curious to see, for example, one PDP10 simulator running TOPS10, one Hercules simulator running OS360, and even one SDS simulator (software ?) with simulated IMPs attached. Don't you think so ? Thanks and Greetings Sergio

classiccmp server issue

by jwest＠classiccmp.org

Sometime around 3am this morning, the classiccmp server tossed cookies. Not sure exactly what happend, I tried powering it off and back on remotely - no joy. So, this afternoon (sorry, but I was busy gutting (refurbing) another HP 7906 drive and for once I decided my collection comes first!). I went down to the datacenter and hooked up a console. Got this wonderful message: "HDD S.M.A.R.T. monitoring has determined that a hard drive failure is imminent. Back up your data immediately. Press F1 to continue" *sigh* So I hit F1, made sure it came back up. All disks were present and accounted for. Tonight I'm sending copies of the filesystems over to a different server... just in case. Not sure how much I trust S.M.A.R.T., so I may let it ride for a while and just keep a closer eye on it. We'll see. On the bright side, my 2nd 7906 is now mechanically sound, servo/positioning tested ok too. On to the diags tomorrow for some read/write tests. What *IS* it with me and hard drives these days anyways? If it's not vintage ones, it's modern ones! Also I thought I'd try throwing this hook out - Does anyone have any 7906 drives that they are sure are junk and not worth keeping? If so, I would like to scavenge them for a spare set of cards from the card cage, the PMR board, and all the heads - especially the servo head. But only if it's pretty certain the drive isn't worth keeping and refurbing. Regards, Jay West

Hubs work fine, but only some switches. Any normal Layer-2 switch should pass Ethertalk packets. Some Layer-3 switches can do protocol filtering, and might not (or might be configured that way) but any self-respecting ordinary Layer-2 switch shouldn't care whether the next protocol up is Appletalk, DECNET, IPX, IP, ARP, ... -- Pete Peter Turnbull Network Manager University of York

HP2000 goodies tape conversion

by Chapmangregw＠aol.com

Hi, I have a backup and a hib tape for the HP2100A. I live in eastern Iowa, USA. (Iowa City to be very exact). Does anyone in reasonable driving distance have a reel tape drive that can read these old proprietary(?) tapes? (I'll start reasonable and then expand my begging circle :). (oh, and please do not hold aol against me, it is due to finances). Thankyou for your attention, Greg

I should agree too other providings > of Internet RFCs or STDs retired of the official list. You may have some trouble finding that, as it was one of the very few RFCs/STDs that wasn't ever online. You'd have to find a library that has an old copy, or find someone who has scanned a copy. Old RFCs aren't normally taken offline, so my "dump" of RFCs from around 1998 should be complete -- apart from ones that were never online in the first place, like RFC0007: 0007 Host-IMP interface. G. Deloche. May-01-1969. (Not online) (Status: UNKNOWN) which is a discussion about the software part for the interface This particular one *is* now online, with the following Editor's comment: [The original of RFC 7 was hand-written, and only partially illegible copies exist. RFC 7 was later typed int NLS by the Augmentation Research Center (ARC) at SRI. The following is the best reconstruction we could do. RFC Editor.] and the text is at http://asg.web.cmu.edu/rfc/rfc7.txt -- Pete Peter Turnbull Network Manager University of York
