Therefore, the PCB can only store small sec-
tions of the game program at a time.
SUBJECT
The Sega System 24 games (See figure 1) use an
FDD (Floppy Disk Drive) memory storage sys-
tem. The disk is used to store all game program
information that was traditionally stored in E-
Proms along with some game bookkeeping and
difficulty setting information.
THE DISK SYSTEM HAS A COUPLE OF MAIN
BENEFITS THAT INCLUDE:
-a-=
--
Hot Rod
Due to the fact that the disk is written to, and
read from, many times during the game, wear
may result causing eventual disk failure.
Because of this, it is recommended to keep a
good copy of the disk as a spare to prepare for
this.
DISK TYPE
The type of diskette used in this game system
is a 3.5 inch DS/HD (Double Sided/High
Density) floppy diskette. This is a standard
type diskette which is used in IBM PS-2 com-
puters and can be purchased from any com-
puter supply store.

OPERATION
The game PCB accesses the disk system
throughout the game as a traditional game
would access E-Proms. This must be done
many times throughout the game due to the
fact that there is much more memory storage
on the disk than there is RAM on the PCB.
BACKUP PROCEDURE
To copy a diskette, simply follow the steps
listed on the following page. These steps apply
to all System 24 games made by Sega.
