[net.micro.cbm] Any alternative to Commodore Datasette?

km@emory.UUCP (Ken Mandelberg) (03/01/84)

I have decided to use a Vic 20 (or maybe a C64) as a
controller, running a dedicated program. The Vic is
cheap enough now a days, but the Datasette seems out
of line in cost, especially for backing up one program.

Is there a cheap way to adapt the Vic to an ordinary
recorder? 

Better yet, is there a cheap way to add some eprom where
I could put the dedicated program?

All the address and data lines, plus some decoded select lines
are available on the expansion bus - which uses a standard 22/44
on .156 centers for the edge connector.  You ought to be able to
burn your program in ROM and put it at $1000 (or $0400) so that
when you power up, you can simply type run and away you go with
a basic program in ROM.  If you are willing to get deeper, a
machine language program could auto start on power up.  (This method
applies to the VIC20 - the 64 has a different connector and would
probably be an over kill for your application.)

I don't recommend mucking up an audio recorder.  You get what you
pay for.
