The Memory Test is adapted from "Memory Test" by Jim Butterfield which appears on pages 122 and 123 of THE FIRST BOOK OF KIM, edited by Butterfield, Ockers and Rehnke, published by Hayden Book Company. The book sells for $9.00 and is a must for any 6502 user. 2. The program listings in this manual were produced by the Micro-ADE Assembler on a KIM-1 with a MEMORY PLUS board. The COMPUTERIST version of Micro-ADE includes a cassette tape with two versions of Micro-ADE. One has the program in 2003 to 2FFF and uses 3000 to 3FFF for the Source and Symbol working areas. The other has the program in C000 to CFFF and uses 2000 to 3FFF for the Source and Symbol working areas. This second version is ready to be placed into EPROM and left resident in your MEMORY PLUS board. Micro-ADE costs $25.00 for the Operators Manual and Cassette Tape. This Manual includes most of the Inputi Output Source Listings so that the user can customize the package to his type of terminal. Complete Source Listings are available for an additional $25.00.
