A prototype of the hardware was done almost 2 years ago, but it wouldn't do to release it without software. I wrote a serial driver, a parallel driver by Paul Coward is on the way, and Jeff Lavin has written a plethora of excellen t utilities including a serial preferences progra, a clock program, test progra ms, and more. We also wrote a program that intercepts OpenDevice to permit use with older programs that don't let you specify the driver name and unit. It pops up a nice window asking you to select which unit you want to use. Naturally we supply 100% source code for everything, and users are encouraged to modify the code (hopefully sending the result back to us, eh? :-)) We also expect many users will write custom software for their applications that use the parallel IO. We'll try to provide enough documentation and examples to help you do so with a minimum of effort. -- Dan Babcock
