Beginning ML #2

Yes, the infamous learning machine langauge tutors by Craig Taylor
(duck@pembvax1.pembroke.edu). In this session we examine indexed addressing
and it's usefullness in printing strings of characters.

An In-Depth Look at the 8563 Video Chip on the C= 128

This article documents and details the 8563 in-depth. It covers all
available registers, documents their functions and suggested methods of getting
certain effects. Also covers how to read and write to 8563 registers as well
as read the 16k or 64k of memory that contains the VDC char-set, screen memory
etc.

FILE SPLITTER

Now there's a way to transfer files of any length from MS-Dos diskettes using
a public domain program that will only read files of 43k or less and a IBM
program to split the files up. There are better ways, but if you don't want
to pay for Big-Blue Reader this is one method to go.

BANKING ON GEOS

GEOS 128, being an extended and expanded version of GEOS 64, provides a
contiguous block of application space in a single RAM bank. The "standard"
programming documentation makes few references to the use of other banks in
GEOS. This article describes accessing other RAM banks (including RAM banks 2
and 3 for 256K expanded 128's) under GEOS128, using both the GEOS Kernal
routines and more direct methods.

DYNAMIC MEMORY ALLOCATION FOR THE 128: Breaking the 64K Barrier

This article examines how to implement and use dynamically allocated memory that will allow your programs to better utilize all of the available memory on your C=128, including expansion memory. These routines are extracted from the Zed-128 program which is a text editor that can edit 600KByte files on a 512K expanded 128.
