Second "Disk of the Quarter"

The second AALDQ is ready!  If you would like to have the source code on disk in S-C Assembler II Version 4.0 format for all the programs which have appeared in AAL issues 4, 5, and 6, then send me $15.  I will send you the disk, and you already have the documentation.  DQ#1, covering issues 1, 2, and 3, is also still available at the same price.


Some New Books about the 6502

Apple Machine Language, by Don Inman and Kurt Inman, published by Reston (a Prentice-Hall Company).  Hard cover, 296 pages, $14.95.  If you are an absolute beginner, this is the book for you.  You start by typing in an Applesoft program which helps you POKE in machine language code, and CALL it.  Most of the examples involve lo-res graphics and sound.  One chapter describes the Apple Mini-Assembler (which resides in the Integer BASIC ROMs).  They never get around to a real assembler.

Practical Microcomputer Programming: the 6502, by W. J. Weller, published by Northern Technology Books.  Hard cover, 459 pages, $32.95.  Over 110 pages of the book are devoted to a listing of an assembler and a debugging package.  A coupon inside the back cover can be redeemed for a tape copy which will run on the Apple II.  By adding $7.50 to the coupon, you can get a disk version.  The package can be loaded from the disk, but there is no capability for keeping source or object files on disk.
