Check into Martix Orbital - Serial displays of all shapes and sizes - they're cool
Check out Browndog Prototypes' Links page for other places with good information about wire-wrapping.
More basic wire-wrapping information from University of Utah Computer Science department. Gives some good help with using the wire-wrapping guns.
RS-232 Information from EPL Ltd. They also have a wide selection of other information regarding Telecommunications.
Ascii Table: Has all of the characters from 0 to 127 (decimal). Very useful for debugging serial communication. :)
Stepper Motors: Very good tutorial by a professor at the University of Iowa
The Chip Directory contains a lot of good information about semiconductor devices especially how to contact (almost) any manufacturer of the devices.
Gray's Semiconductor Website: Another Really good site that provides links to semiconductor manufacturers. Especially useful for figuring out who actually made that chip you found.
Cables and Connectors: Ionsys has pinouts for almost any type of cable or connector you might need.
ElectroBase allows you to search through a very extensive directory to find out who stocks parts from specific manufacturers. This can be very useful for tracking down the "perfect chip" you found in some data book.
EE stores is, in my opinion, the best place to get chips (that is, if they have them in stock and happen to be open).
Active Electronics, located in Bellevue is a great local chip supplier. Some of their other parts (like wire-wrap stuff) are somewhat overpriced, but you can't beat actually looking at them and getting them immediately.
13107 Northrup Way,
Bellevue, WA 98005
Vector Electronics, located next door to Active Electronics in Bellevue is essentially an electronic junk store. They have miscellaneous parts at really cheap prices. Most of this is buy at your own risk though and you will probably have to experiment to figure out how it works. I have found some great stuff there. Stop by and browse around when you go to Active.
Radar is located in downtown Seattle. Check web page for exact location. Don't know too much about them though.
Of course there is the old standard Radio Shack. For the most part I find them to have little selection and be way overpriced, but sometimes, they are all that is available.
Jameco is an excellent supplier. In general their prices are very reasonable and they will get it to you as fast as you are willing to pay for. I would suggest trying to figure out everything you might possibly need and making one big order to save on shipping. You can even search their online catalog and place your order there.
Tip: If you order wire-wrap sockets from them, specify square leads, otherwise, you might end up with round ones.
Digi-Key is probably one of the largest chip distributer out there. If you have found a chip from some manufacturer, chances are, they will sell it to you. Warning, prices can be steap for small quantities. They also carry other miscellaneous parts.
Newark Electronics has almost anything imaginable related to electronics in their catalog, the only problem is that their prices are rather high. This can be a good place to start to look for parts (and find out if there is something available).
3M produces sockets for some surface mount chips. If you can't find a socket anywhere (including their web site), give them a call and they might be able to help. They do make other sockets that aren't listed on their web site. You probably won't be able to get wire-wrap sockets, but at least you will have decent sized pins to work with.
Browndog Prototypes is another supplier of sockets for surface mount chips. It appears that their selection is also rather limited at this time but you might actually get wire-wrap pins on your socket. Be forewarned that you will pay dearly to get wire-wrap pins. If at all possible get your chips in a DIP package.
Note: They also have a good links page with information about wire-wrapping and general circuit design.
Arrow Semiconductor Group. Don't know anything about them, but they were recommended by a student.
Also a great place to get small quantities of chips (otherwise known as "samples") is directly from the manufacturer. Go to the manufacturer's web pages to see if they do this. At this time, I know National Semiconductor does this extensively. You can also probably sweet talk you way into some samples from some distributers. This would be a place like Wyle that distributes to large manufacturers, not Active.
Cupl Starter Manual. Unfortunately, doesn't contain code examples.
Cupl Trial version. Many code examples, but limited capabilities.
State Machine Cupl. Draw your state machine and get Cupl code, but limited to 8 states.
From here you can download a very good restricted version of Verilog. The sources is also available on the class web page under get your code here. Select the veritools directory.
Wellspring web page. From here you can download a restricted version of Verilog. Be sure to read all the comments and instructions on the web page.
