[net.micro] commodore cassettes

allan (04/27/83)

In response to a previous question about
using non-commodore cassettes I offer the
following.  I have constructed an "interface"
for my VIC using a small piece of vectorboard, 2 LED's
 an old earphone from a transistor radio, and a low
voltage relay.  The relay controls the cassette's
motor, the LED's and earphone give audio and visual
indication of data transfer.  It works very well
with data stored from my VIC but it is a problem
trying to use a tape recorded on another machine
or a factory tape.  This leads to a big problem
that I need help from the new.  I am using the
Commodore VICTERM program as a communication
program but due to the non standard cassette
I have great difficulty loading it.  If I could
save the program back out on cassette once properly
loaded I would have no problem BUT due to the
protection system used by commodore on their tapes
I cannot save it.  This seems to be due to
a certain section of memory that the save routine
will not access.  If anyone has any ideas on how
to get around this I would be most greatful.
Also, if anyone has any experience with the
commercial  products that allow connection
of any cassette to the VIC and 64 I would
like to know how they perform.
Thanks in advance for any info,
