Bud's question was about a spring wound CAPSTAN machine, NOT a battery
motor machine without a capstan.   Yes, there were rim drive battery
motor machines, but that was NOT what the original question was about. 
Did your AIWA have a spring wound motor?  No?  Did it have a capstan run
by that spring motor?  No?  Then why do you keep on bringing it up??? 
As I've already answered, the machine Bud Black asked about was a
Magnamite spring wound machine made by the Amplifier Corporation of
America, NOT a rim drive non-spring machine.
