CHAPTER 1

INTRODUCTION

RAMCard is a printed circuit board that contains 16K bytes of additional random-access memory (RAM) for your Apple II or Apple II Plus computer.

RAMCard is designed for an Apple II with 48K bytes of RAM already in place. If your Apple II has less than 48K RAM, you will need to purchase enough 16K memory modules to bring your Apple II up to 48K.

RAMCard is compatible with Microsoft Consumer Products SoftCard, a circuit card for the Apple which contains a Z80 microprocessor, and allows you to run the CP/M operating system. RAMCard and Soft- Card together make a powerful combination that turns your Apple II into a full memory (56K), flexible (two microprocessors) microcomputer.

With RAMCard and SoftCard in place, you have 56K RAM available to run any of the languages available for the SoftCard, including Microsoft’s BASIC-80 (included in the SoftCard package), COBOL-80, FORTRAN-80, BASIC Compiler, and Assembly Language Development System.

RAMCard contains 16K of memory. But, because only 12K of additional addressing space is available in the Apple, 4K of addressing space must be shared by two 4K memory banks. This means that only 12K of RAMCard RAM is available to you at a given time.
