: How To Write Protect Your Ram Card :


 Here we are going to explain how to wr
ite protect a ram card. To protect you s Witch to a ram card is slot 0. By doing this the user can load a program into the card and it will not be distroyed when a protected disk is booted. The ins-
pector could be used along with reloca-
ting fid or a sector copier such as lhs
copy or any other utill. that uses the
swrt(read and write track sector).when 
the disk is booted it will appear as if
ram card it will look like a rom card a
nd so it will not be cleared. to make the Is switch you will need a chip puller, soldering iron, toggle switch, and some thin solid copper wire. take the 74lS13
8 chip out of your apple. it will
is located directly below the slot 0 so
cket and four chips to the left of the 
 microprocessor(6502). it will say
74ls138 somewhere on the chip and will 
 be printed in white on the motherboard
near the socket from which it came.This
diagram will help you locate pin #7 for
 the modifaction.I might recommend get-
ting a spare 74ls138 if you are unsure
of yourself.

SUPPLY                  PIN #07

First fold pin# 07 up slowly and solder
 one piece of wire to it. Solder the ot
her side of that same piece of wire to
one side of the toggle. Then get anothe
r piece of wire and solder it to the 
other side of the toggle. When insertin
g the chip in the apple place the free
one by the wire that was last soldered
in the place where pin #7 would have 
gone and leave pin #07 on the 74LS138
folded up. Then place the chip back in-
side the apple. When the switch is in
one posession the card will be ram and
the other will be rom. Load your progra
m , protect the card and boot up your
protected disk. For example do the     
  following:                            
    
1. BLOAD LHS COPY,A$D803
2. PROTECT CARD
3. BOOT DISK
4. BREAK OUT OF THE PROGRAM
5. CALL -151
6. 803<D803.DFFFM
7. TYPE 803G

Good Luck!
