You can still buy them, they're called Fisher Space Pens. I carry one all the time and can attest that they do indeed write upside-down or under water, but I've never had the oportunity to try one in zero gravity. They don't work nearly as well as ordinary pens, though. -- Pete Peter Turnbull Network Manager University of York

Does the 64000 do that and > does it show the drive? When you boot the 64000 off the first two diskettes in the operating system set, it checks the HP-IB for any devices attached. If there are no devices attached, you get instructions displayed that state that AMIGO devices - and it names the 9134A - need to be set as address 0. With the drive attached at 0 , it reports the 64000 itself, and an unrecognized device at address 0. > On a 200 or 300 if you press any key druing boot it > will stop the system > from booting an OS but it will go through the search > for drives and display > a list of drives and OSs. I have a untried 9000/300 unit that I picked up last year. Perhaps I could try using that to test with. Will a 9000/300 try to boot without a keyboard attached ? Of course it would hard to press a key to stop the boot sequence without having a keyboard attached <g>. > Is this one of the old wide biege units or one of > the newer square white > ones? > It's the big beige unit. There's no fault light on it, just the power light and the disk activity light. Just to see what would happen, I hooked it up to an HP-1631 and went through the Storage menu to see what it detected on the bus. I can see the activity light coming on when the 1631 tries to access the unit. > I have a couple of those cards and I'm pretty > sure that I have the > manual and software SOMEWHERE but I have no idea if > I can find it. If you > ind them from another source, let me know. The Zia Tech unit is less of a card and more of a programmer's panel sort of device. It has a couple of rows of switches and lights that correspond to the data lines and some of the HP-IB commands. It doesn't seem to have any address setting capability on the outside of the box. Maybe there's a DIP switch inside or something. Looks fun though. Regards, Dave __________________________________ Do you Yahoo!? Yahoo! Mail - 250MB free storage. Do more.

I often look at Italian post on Olivetti M20's. The Italian word for "files" ( used many times in most post ) gets translated to "rows". It took me a long time to figure out how this resulted. Then I realized, it is confused with how solders are positioned on a parade field ( rank and file ) with what we refer to as a file. Dwight

Good plan. I'll try and remember to bring all of ours home with me at the weekend, then I can at least make some sort of list.

Um, your maths is off. Assuming 150 dpi is the minimum acceptable for well-printed text (and some DEC fiche is anything but), and a page is 8" wide, you need 1200 dots per page width. A page width on the fiche you describe is 6/16 inches, so you need 16/6 * 1200 dots per inch, which is 3192 dpi. Another way to look at it is if an 8"-wide page is 6/16" or 3/8" on the fiche, it's .04687 of original size, or about 21 times reduced. So 150 dpi becomes 3200 dpi. The equivalent resolution to get 600 dpi on the original page would be 12800 dpi. -- Pete Peter Turnbull Network Manager University of York

Honeywell Series 16 software

by hachti＠hachti.de

Hi folks, I have recently won an auction for a Honeywell Series 16 (DDP516, H316 etc.) BASIC interpreter manual. Does anyone have this Honeywell BASIC paper tape or a copy of it? BASIC would be a great interactive toy for the Honeywell. And of course I am always looking for Series 16 software - everything. All the original software I have for the machine can be downloaded at my H316 website http://h316.hachti.de. Best regards, Philipp :-)

That's >how they got to venus! > >There are many areas tubes go well beyond what can be done in solid state. > >Randy >www.s100-manuals.com Hi There is a process for CMOS call RAD hardening. It is a process of exposing the CMOS to radiation for a period of time. It reduces the efficiency of the transistors but they don't degrade as fast ( comparatively ) once this is done. As far as solid state goes, silicon is a limiter. Other semiconducting materials can work at higher temperatures. Toyota has worked out a way to produce large quantities of defect free silicon-carbide. This can be used to make transistors that can be run at several hundred degrees C. This is of course interesting to them because they like to have high power transistors for electric cars. Another material that hasn't been used to much is diamond. This is one of the best material to make transistors from since it has such good thermal properties. There are still a lot of processing problem to work out for this to be of much use. They already have the ability to create diamond films. Dwight

Microfiche Scanning

by aek＠spies.com

here we go again... Late last year, I bought a used Mekel 560 (around a $50,000 unit new) I have several thousand sheets of DEC fiche to do as well. Unfortunately, it only handles one sheet at a time, came with no documentation and with everything else going on with my life, I've not spent much time with it since I bought it. It is something I need to get set up soon, though, since there is some material that I need to get done soon.
