HARD and SOFT - The easiest Turbo Load / Save-ep.

 HARD and SOFT


(C) VEL


   Hi! Today we offer you a simple turbo loader. But
is not just a loader. Replacement of all single digits, it can 
turn into a turbo save'er. 

   Well it just because it does not perform error checking disk 
and as a consequence, it hangs. 

   Its main advantages are versatility and small size.
The same loader, but with error checking, is three times
more. If our readers will be interested in this topic,
udovelstviem we will publish a full turbo loader.

   Incidentally, the ZX-REVIEW 5-6/97 (I think) was published a 
full turbo loader / save 'er. But, unfortunately, there lacks a 
few Tag and yes, it seems the authors themselves did not check 
its serviceability - sequence.


   Well, now he is the loader.
