Revision as of 06:23, 18 April 2010

A addon that enables you to make doublicates of tapes and copy software. The device connects to expansion port, and allows to copy data from an external tape deck to the CPC464's built-in tape recorder.

This is probably and adaptation of a similiar device for the ZX Spectrum also by manufactured by Evesham Micro Centre.

Not much else is known about this device. Please supply more.

PREPARATION 

(1) Switch off your computer and plug the Doubler unit onto the
edge connector that is marked "FLOPPY DISC". 

(2) LOAD the Doubler software provided in the normal fashion. 

(3) Plug one end of lead provided into the socket on the Doubler.
Connect the other end of the lead to the EAR socket of a décent
quality mono tape deck. 

(4) Put a blank cassette into the Amstrad's built in cassette
player, put the cassette that you wish to back up into the other
cassette deck. Adjust the volume of the extra cassette deck to
just under maximum. 

STARTING "DOUBLING" 

You are now ready to start the process. Simply follow the screen
prompts and the tape will be backed up. A visual indication of
the process is provided by the flashing border, this can provide
a useful indication to the suitability of the volume setting on
the extra tape deck. The bars on the border should be solid,
looking very similar to a Sinclair Spectrum while loading.

There should be no break up of the border during the pauses
between blocks of data, if this is happening then reduce the
volume of the extra cassette deck. If by reducing the volume
enough to get rid of border break up you lose the solidity of
the flashing border, during blocks of data, it is unlikely that
the extra tape deck that you are using is suitable for the job.

ONCE THE TAPE HAS RUN THROUGH YOUR BACK UP IS COMPLETE.


S P E E D C O P

Once LOADed in the normal fashion Speedcop can be used to make
back ups of all programs using conventional Amstrad loading
Systems. Follow the screen prompts provided.

It is possible as you will see to sélect your own SAVE speed and
to "deprotect" programs. With some long programs it may not be
possible to LOAD ail the program to be backed up in one go. If
this happens SAVE the portion of the program that has been LOADed
then put the original back in and LOAD the rest of the program,
Speedcop will know where to continue from.
