Short answer: no
Longer answer: the 8032 monitor works at a very different horizontal
scan rate, it should be around 20 KHz afair. Also I think the
horizontal and vertical syncs have a particular duty cycle to allow
the monitor circuitry to use less components.
Also, video signal and both sync signals have TTL levels and have separate pins.
A C64 on the other hand has a standard NTSC or PAL video composite (or
monochrome) output (at analog levels).
I'm sure something can be made to adapt this signal to work on a 8032
monitor but I would not attempt that myself anyway.
It would be easier to adapt an old CRT TV set.
