I think I just copied it into the folder that is shown when you follow Start --> Settings --> Control Panel --> Fonts but maybe it must also be registered. See also: http://support.microsoft.com/kb/314960 Adding New Fonts ---------------- Windows supports TrueType fonts or fonts that are specially designed for Windows, and these fonts are available commercially. Some programs also include special fonts that are installed as part of the program installation. Additionally, printers frequently come with TrueType or special Windows fonts. Follow the directions that come with these products to install these fonts. To manually install or re-install a font: 1. Click Start, and then click Run. 2. Type %windir%\fonts, and then click OK. 3. On the File menu, click Install New Font. 4. In the Drives box, click the drive that has the floppy or CD-ROM that contains the fonts you want to add. If you are installing fonts from a floppy disk, this is typically drive A or drive B. If you are installing the fonts from a compact disc, your CD-ROM drive is typically drive D. Double-click the folder that contains the fonts. 5. Click the font you want to add. To select more than one font at a time, press and hold down the CTRL key while you click each font. 6. Click to select the Copy Fonts To Fonts Folder check box. The Windows\Fonts folder is where the fonts that are included with Windows are stored. 7. Click OK. Note On Microsoft Windows NT 4.0, Microsoft Windows 2000, Microsoft Windows XP, and Microsoft Windows Server 2003, you must be an administrator to add and remove fonts.

Normally that can be cured using On the Tools menu, click Customize. Click the Options tab. Select or clear the "List font names in their font" check box. Also, when an administrator installs the font while a user is logged in, the user cannot use it (Office does not show it) until the user logs out and in again. Regards, Arie de Muijck > Anyone know of a cheap (or free) Timing Diagram tool? > > I need to communicate with my digital counterparts on an IC design ;-) Arie's hint is great. But it'll be lots of typing. If it isn't for doc purposes but just for mutual understanding there is an easier way. This Saturday me and my layouter (with him being in Vermont) just could not get onto the same page with a weird kind of laser diode mounting (z-bend, then rotate a bit and lay flat over some discretes). So I sketched it up, scanned that in and zipped it over. Tada! Problem solved, layout is now done. But the fab people haven't come back with a quote for hours now. Hope that doesn't spell trouble.

This has freed up a lot of space in my office plus I have better redundancy now. It has so many buttons that I just discovered a new one after over a year: It can scale copies. Yeehaw.

One of my customers >> jokingly asked me what CAD package I use, and I answered "Sharpie." > > Didn't Bob Widlar call that his "Mexican Computer"? Nah, that was Teledeltos paper. It was electrically conductive, with a sheet resistance of something like 10k ohms per square. You cut it with an X-Acto knife, put a voltage across it, and it solved the 2D Laplace equation for voltage drop vs position pretty well. I went looking for some a few years ago--it had been picked up by a British outfit, allegedly, but they didn't seem to have any for sale any more.

SignatureRegards, Joerg http://www.analogconsultants.com An eraser shield is a small piece of stainless steel, about the size of a credit card and very (0.010" or so) thin. It has various size cutouts in the steel, some circles, some radiuses, some straight lines, some ! teardrops, etc.. You put the shield over the part you want to erase a tiny portion of and erase like hell without worry about erasing too much. I've still got a working electric eraser (both plug-in and cordless) if anybody needs one. Otherwise they go to the engineering museum when I kick off. Jim > Agree.

There have been times where I had to use a razor blade more than once in the same spot. The first instance could be somewhat muffled by rubbing a fingernail over it but the 2nd razor application definitely showed. By the 3rd there was a hole... The ME guys had some kind of "cheat vellum" where you could peel off a layer and it almost looked as if nothing ever happened. Very expensive though but it did prevent the ink from frazzling out too much.

Particularly if one is a visual/spatial thinker, it helps with the conceptualization process. Some years ago, I was responsible for maintaining a rather complex engineering document management an configuration control system (built in house). All of the diagrams in my documentation were done by hand on quad ruled paper. From time to time, management required that an 'official' version be done by the CAD group, but I came to find out that the IT folks had taken to distributing copies of my drawings to the various support groups and shelving the CAD versions. One (new) manager had requested that the CAD group produce an overview data flow diagram by combining all the individual diagram pages into a single sheet. It was about 36x48 inches with small (10pt) font labels and symbols. The story was that as soon as he saw the system he was to take responsibility for on one page, he quit. My drawings were 8.5 x 11 sheets with each sheet being the data flow or E-R for a single event (weekly backup, new version checkout, etc.) making the system a lot easier to comprehend.

"This software package provides a command line tool for documenting hardware and software designs through timing diagrams. It reads signal descriptions from a text file with an intuitive syntax, and outputs a timing diagram to an image file. Notation typical of timing diagrams found in the Electrical Engineering discipline is used, including arrows indicating causal relationships between signal transitions." It is a mainstream Linux package and should be easy to obtain. (It is part of the Debian distribution). SourceForge should certainly have it. Mark Walter |
