SUBJECT
Attention everyone! Fluorocarbon based sol-
vents are being phased out of the electronic
industry with a target date of 1993.
About those containers you needed for small
parts, go to a Target or a K-Mart and check in
the sporting goods department. I have found
that the boxes sold for fishing use to be
mighty handy.
Most of them are made of the same plastic as
the VCR tape boxes, but they have a real
hinge instead of the flexed edge used for VCR
tape boxes. They are also made of thicker
material.
Additionally, they are divided into different
interior compartments to allow you to keep
the nuts from mixing with the screws (and
lord knows what can happen then!).
Another box I found has two lids on opposite
sides with 15 compartments. The compart-
ments each will hold 5 fuses. Two other com-
partments will hold even more. This one
small box holds every fuse that I need for
99% of my repairs, and it's easy to see which
fuses you need when you get back to the
shop.

All service managers are encouraged to
explore other avenues to reduce the use of
fluorocarbons. (Fluorocarbons are proven to
be responsible for the destruction of our
fragile Ozone layer).
Cramco is currently distributing "No-Clean"
solder. It's the same price as regular solder.
Chemtool is working on a freeze mist based
on liquid nitrogen and a solvent with a
Methyl Chloride base.
Rolin/MMs has more information on the
solder and are currently shipping some
FREE samples. Their number is 213-927-
2245.

SEGA SYSTEM
24 FLOPPY
DISK DRIVE MEMORY SYSTEM

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.

AND DIRECT SUNUGHT!
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.
