دانلود کتاب Compute!’s mapping the IBM PC and PCjr

The IBM PC, in all its permutations, is a powerful machine. Unfortunately, many of its most powerful features—its builtin hardware and software—are hidden and not well-documented. Even relatively simple things may seem impossible if you're using a trial-and-error approach. How can you call DOS and BIOS functions from BASIC programs? Is there a way to tell, from your program, what version of DOS or BASIC is being used? Can you turn off the Ctrl/Break sequence from BASIC?

If you use an IBM PC, XT, XT/370, PCjr, Portable PC, or a 8270PC, COMPUTE!’s Mapping the IBM PC and PCjr will show you how to do all this and much more. Here’s a brief look at just some of what you'll find in this extensive reference guide:
