/* Description: This program will test the hardware interface for the */
/* TNT and MC68340. In particular it will test the three */
/* different types of I/O: Programmed, Interrupts, and DMA. */

/* WARNING : DO NOT USE THIS PROGRAM IF YOU USE AN INTERRUPT LEVEL OTHER */
/* THAN IRQ3 OF THE MC68340 AND A BASE ADDRESS OTHER THAN */
/* $FFFFE800. YOU CAN CHANGE THE BASE ADDRESS AND INTERRUPT */
/* LEVEL IN THE HEADER FILE AND RE-COMPILE THE SOURCE CODE. */

/* WARNING : THIS PROGRAM USES THE MC340BUG LIBRARY. THEREFORE TRAP #15 */
/* IS NOT AVAILABLE FOR USER PROGRAMS. PLEASE REFRAIN FROM */
