ÿþMEMORY DUMP/LOAD

The memory of the SDS 7 can be externally expanded by dumping 
programs onto a RAM pack (optional extra).

The internal memory can be divided into two sections for this 
purpose giving the choice of loading or dumping in the Low 
section (kits 1 - 39) or the High (kits 40 - 79).

The dumping procedure is as follows:

Insert the Memory Pack into the socket on the rear panel of the
SDS 7 switch the protect switch or the memory pack to 'unsafe' 
and press buttons D,U,M,P in sequence. You then have the option
of dumping "HI or LO" by pushing either button 1 or  13 (with 
lights flashing)

The visual message AC indicated a successful operation. You will 
then have a copy of either kit No.s 1 - 39. (If you dumped lo)
or 40 - 879 (if you dumped hi) stored in the memory pack. Switch 
the protect switch to 'safe' and remove the memory pack.

NOTE: You should leave the memory pack inserted in the SDS 7 
(with the SDS 7 switched on) occasionally (1 a month)   for a 
period of a few houri, to charge the memory packs' batteries.

The procedure for loading is the same but buttons L,O,A,D are
used instead.

Should the message CF appear the transfer of memory has failed 
and should be repeated.
