Apple Desktop Bus

Abstract: A tool for building Fitts' law models is described. MODEL BUILDER runs on the Apple Macintosh using any device which connects to the Apple Desktop Bus. After 16 blocks of trials taking about 4--5 minutes, the program provides an immediate (albeit tentative) statistical analysis, showing the coefficients in the prediction equation, the coefficient of correlation, and a regression line with scatter points. MODEL BUILDER can be retrieved anonymously by researchers, educators, developers, or anyone with access to INTERNET through file-transfer-protocol (FTP).

Abstract: This text offers coverage of the full computing potential of the Apple Macintosh computer. It also covers troubleshooting techniques for hardware and software problems and deals with all the Macintosh models and compatible peripherals.

Abstract: Updated and expanded, this is an introduction to MAcintosh technology. IT includes insight information about the Macintosh family of computers and covers an extensive list of issues including: the System 7 operating system; an introduction to and comparison of all Macintosh models, including the new Portable, the IIci and the IIfx; details on hardware peripherals; an analysis of Mac software and programming issues; advice on troubleshooting Mac problems; information on communications between Mac and other computers and much more.

Abstract: An ASIC (Application Specific Integrated Circuit) cell implementation of an ADB (Apple Desktop Bus) bus controller with programmable timing value registers for the Apple Desktop Bus (ADB) has a system interface for connecting to a computer system including an address bus interface, a data bus interface, and a control bus interface, and has an ADB interface for connecting to an ADB peripheral bus. A control state machine within the ADB bus controller uses timing data from the programmable timing value registers to implement the Apple Desktop Bus data signaling and communications protocol on the ADB interface.
