S-C Macro Assembler Version 2.0
(PrODOS Based)

Here is your copy of the latest upgrade to the S-C Macro Assembler.
The most important new feature is that this version is based on
Apple's new disk operating system, ProDOS.  Several other
improvements have been made, with the result being an assembler that
is even easier to use, and yet faster and more powerful.

The disk contains the most recent version of PrODOS, as released by
and licensed from Apple Computer.  This includes the PrODOS MLI
version 1-1-1, BASIC.SYSTEM version 1-1. FILER, and CONVERT.  We
modified FILER slightly, for simpler operation from the S-C Assembler
environment.

When you boot the disk, SCASM.SYSTEM will be loaded and installed.
SCASM.SYSTEM includes a command interpreter (similar to
BASIC.SYSTEM), the S-C Macro Assembler, and a selection of various
80-column I/O drivers.  If you are booting in an Apple lie or i/c,
that 80-column driver will be automatically installed.  If not, a
menu will appear offering you a choice of 40-column, Videx Videoterm,
Videx Ultraterm, or STB-80 drivers.

The source code for each of the drivers is included on the disk, so
that you may modify them as you wish or create your own for other
80-column cards.  Note that the Videx Videoterm driver is compatible
with Applied Engineering's Viewmaster card as well.

Other files on the disk include a program for easily LOADing an S-C
source file from a DOS 3-3 disk into the ProDOS environment, and
various example programs.

As is true of all S-C products, the disk is not copy protected in any
way.  Make a backup copy now, and store the original in a safe place.
The FILER program can make such a copy, or you may use the DOS-based
COPYA program, or any other copier you have.  You may also use FILER
to move copies of any individual files from this disk to any other
disks you have, including hard disks or RAM disks.


We expect you to make as many copies as you wish for your own and to
encourage your friends to buy their own copies.

Comparison with DOS-based Version 2.0

We have tried to make the transition from DOS to ProDOS as easy as
possible. making as few changes in the way you operate the S-C Macro
Assembler as we could.

As a result, if you are already familiar with the DOS-based version
and with the operation of ProDOS, you cam probably begin using our
ProDOS version without reading any further.  However, we recommend
you do read what follows, to pick up t
