How to Use This Guide
Section 1 introduces you to the 1764 RAM Expansion Module, and tells
you a little bit about what you can do with it. There are installation
instructions, and a few warnings you'll need to be aware of.
If you are a beginning to intermediate level programmer, you will find
the programs on the 1764 Test/Demo disk indispensible in utilizing the
additional memory. Section 2 concentrates on the software programs
included that were specifically designed for use with your 1764, and
should be helpful for all users, regardless of level of programming
experience.
The software also enables you to run the RAMDOS, an operating system
based in the RAM Expander that lets you perform disk operations
quickly and easily. Section 3 provides technical and programming de
tails on the RAMDOS, for both experts and novices.
If you intend to write your own programs to use the 1764, you will also
find the programmer's reference notes useful. In addition to the mem
ory map and details about the 1764 registers, this section has a sample
program to load and recall a text screen using the 1764. Section 4 also
includes information about the RAM Expansion Controller and other
technical features of the 1764.
