Help Wanted Picking Items from NASA

by jrkeys＠concentric.net

Good Day I have been given a chance to submit a wish list to NASA for artifacts for the museum I started here in Houston and wanted suggestions from the list of items you would want to see on display from NASA's past. Please email me off list or you can share your input with the list. Thanks John

single transistor projects?

by jhawes＠hawestv.com

Rufus Turner wrote a fabulous book on single-transistor projects. I reviewed the book for Amazon. See... http://www.amazon.com/125-One-Transistor-Projects-Rufus-Turner/dp/0830695370 You have to be careful with early transistor projects. Most of the transistors are germanium. After making circuit changes, you can build these circuits with modern, silicon parts. At minimum, the silicon transistors require changes to the bias circuits. (Sometimes, you'll need to make other changes, too.) For help with the changes, refer to my page at... http://www.hawestv.com/transistorize/germanium1.htm Equivalents to some early semiconductor types are unavailable today. (Or available only as used, or new-old stock parts). Such semiconductors include tunnel diodes, unijunction transistors and most early FETs. Redesigning circuits with these parts could be rather difficult. James T. Hawes

Two recent vintage computer sightings in movies

by tiggerlasv＠aim.com

While it's not a movie, if you watch carefully on the Star Trek: Next Generation pilot episode "Encounter at Farpoint", you'll see what appears to be a VT100 sitting on a pedestal on the bridge. . . an interesting prop. ;-) T

Fwd: [comp.sys.sgi.hardwar...] Power Challenge XL available

The computer was cleanly shut down on May 5, 2004 and since that time was not touched. We intend to scrap it now. If anybody wants to have some spare parts or even the complete beast, let me know within 1-2 months. I regret to say, that this was the last SGI machine we have here. Anyway, I would like to express my thanks to the SGI admin comunity for all the help I've received in past years. Sincerely yours, Cyril F.

HP-1000 HP-IB / GP-IB IEEE-488.2, etc

by Tim＠Rikers.org

HP-IB, GP-IB and IEEE-488.2 seem to refer to the same more-or-less compatible bus architecture. http://en.wikipedia.org/wiki/IEEE_488 I'm hoping to get GP-IB storage setup on my HP-1000 systems eventually. I've picked up: HP 59310-60101 "BUS INPUT/OUTPUT INTERFACE" - low speed GP-IB card HP-9122C - dual 3.5" GP-IB floppy drive (Thanx Stan!) However I don't have the cable to wire from one to the other. The drive has a standard IEEE-488 connector: http://en.wikipedia.org/wiki/Image:IEEE-488-Stecker2.jpg But the controller has a 50 pin card edge connector. Anyone have a spare cable? I've been looking at some GB-IB software tools: * http://www.hp9845.net/9845/projects/hpdrive/ emulates GP-IB drives on win32 * http://www.hp9845.net/9845/projects/hpdir/ read and write to some GP-IB media and filesystems from win32 * http://linux-gpib.sourceforge.net/ Linux GP-IB drivers and libraries. This does NOT include drive emulation or access, but it aimed at sensors and other devices that speak GB-IP Not all drives use the same protocol over GB-IP. Bitsavers has documents that cover the AMIGO and CS/80 command sets: * http://www.bitsavers.org/pdf/hp/disc/ Lots of drive docs including: * http://www.bitsavers.org/pdf/hp/disc/subset80_Jul83.pdf SS/80 and by reference some of CS/80 I do not currently have a GP-IB interface for a PC. The National Instruments PCI-GPIB cards seems popular on eBay. There are also USB-GPIB converters from NI and others. The ISA or SBus cards go for less, but then I need to find a machine with one of these slots. :) I understand that HP-7920 and HP-7925 drives were AMIGO flavor GP-IB drives. Perhaps the HP-7905 and HP-7906 as well? I'm not quite sure where the GP-IP buss comes in the picture. There is normally a contoller (13037-60028) interface between the drives and the host computer interface (02640-90042?) I presume that the bus on one side of the 13037 is IEEE-488 but I'm not sure which. Can the 026xx cards directly attach to GB-IP drives? How does the shared storage through a 13037 controller work? are they all just IDs on GB-IB? Any insight appreciated. Any hardware donations greatly appreciated. :) -- Tim Riker - http://Rikers.org/ - TimR at Debian.org Embedded Linux Technologist - http://eLinux.org/ BZFlag maintainer - http://BZFlag.org/ - for fun!

Polymorphic System88 disk

by cclist＠sydex.com

> Date: Tue, 8 Apr 2008 05:59:37 -0700 > From: dwight elvey Will all respect for your efforts, Dwight, at least you knew the origin of the diskette and had a faint idea of what might be on them. You haven't lived until someone shoots you a bunch of diskettes with everything being unknown--the modulation technique, the code representation, the data rate or track spacing or byte width, much less the file system. Your Polymorphics floppies sound a lot like a bunch of diskettes I got in recently from a manufacturer's in-house PCB stuffing robot. The format appears to be a "roll your own". It's hard to say which is the most fun--diskettes discovered to be GCR where you have no idea of what the group size is, nor what the groups correspond to. Or diskettes written on something like a typewriter where the code's not ASCII, nor does A immediately precede B--and you have nothing that says "this is a printout of what's on the diskette". Hint: You start with a statistical analysis of the pulse stream and go from there. For me, it's a lot of fun, ferreting out things by bits and pieces until the big picture emerges. Cheers, Chuck

The Unix Haters' Handbook

by cclist＠sydex.com

> Date: Mon, 07 Apr 2008 14:04:01 -0400 > From: Sridhar Ayengar > That's bull. There are ways to make grep output something like "No > matches" without breaking a pipeline that uses it. I suggest that > perhaps those who say "They're the kind of thing people who don't use or > understand pipes will say." are the ones who truly don't understand pipes. If anything, my issue with the evolution of *nix is that the original philosophy of "write a bunch of simple tools and hook 'em together via pipes" seems to have been deprecated in the almost 30 years since I began using Unix. There seems to be a trend of proliferating options. Quick, who can recite from memory all of the switches and their meanings for GNU tar? I can't. Who can understand the tar man pages? Who knows it to be accurate for the particular incarnation of tar that they're using? Cheers, Chuck

Free to a good home - IBM PS/2 stuff

by ddsnyder＠zoominternet.net

Somethings a miss here... resending... On Mon 04/ 7/08 7:36 PM , "Daniel Snyder" sent: To all, I am unloading all of my PS/2 gear, most of the systems may be too heavy to ship, but will part out. I'm out of space and my real interests have always been DEC, almost 30 years now. This is by all means not a complete list, I will continue this list as I uncover more. All has been stored indoors in a dry and heated area. 2 - Model 25's B&W (ISA) 2 - Model 30's (ISA) 1 - Model 65 tower (MCA) 1 - Model 80 tower (MCA) 1 - Model 50 desktop (MCA) memory modules, video, esdi drives, scsi drives, some good working floppies. I have most if not all of the config disks and copies on cd. I think the 80 has a worm drive and colorado/maynard? QIC tape, spare motherboards for the 50, 60, 70 and 80. Would really prefer local pickup (or relay or within 100 miles) That's all for now Dan Snyder Butler, PA 16001
