ATTENTION ABSOLUT BETAVERSION NO GUARANTEE FOR ANYTHING!!
-Betadisk reads on my A4000/EC 030 from DF0: every spectrumdisk
written with BetaDisk-interface in format 3,5"DS80 into an imagefile.
-GetFreezer examines an imagefile, extracts Betadisk-freezer-files
and converts them to '.mirage' format.
I made this two progs, because I wanted to read the Freezerfiles
of my ZX-Spectrum Betadisk-Interface.
I decided to make them freeware, so if you find them usefull, or
you ecpected more, mail me. It will inspire me.
Excuse my bad english and this lousy stuff.
Andreas
PS.:
Betadisks are formated with 80 tracks/16 secs.
One sector is 256 byte long.
