A Mini Apple Network For Apple Ii Plus Computers, Michael E. Harnage
A Mini Apple Network For Apple Ii Plus Computers, Michael E. Harnage
Retrospective Theses and Dissertations
Computer networks have become increasingly popular over the last ten years. A simple low cost Mini Apple Network that uses Apple II plus computers and Apple's Parallel Interface Cards, is presented here. The Mini Apple Network is driven by PIC DRIVER, a software program that is able to transmit an Applesoft array variable from one computer to another. Three application programs are presented. A comparison is made of the gain in execution time when one, two, and three computers are used to solve the same problem, namely Laplace's partial differential equation. An increase in gain was obtained when the number …

An Evaluation Of The 8051 Microcontroller, George C. Schafner
Retrospective Theses and Dissertations
With the increasing availability and use of 16-bit microprocessors, the 16-bit data bus and is becoming more prevalent. However, many peripheral devices such as printers and tape/disk drives still require an 8-bit data bus for their interface. This paper will explain how an Intel 8051 microcontroller may be used to interface a 16-bit data bus to a peripheral requiring an 8-bit data bus. A FIFO is used to buffer data from a 16-bit processor so that efficient use of processing time is maintained. The 8051 is used to control the peripheral and data transfer.
