I'm looking at an old film recorder, the Polaroid Freeze Frame, the back of the machine pictured here:

I believe the output to 35mm film was 640 x 480, but im not sure, I can't find any info online confirming this.
What im wondering is, can a digital signal can be fed into this machine, increasing the resolution.
I know there are converters for everything these days.
Can someone explain the connections available on the back in detail to me, from the time (1985) and if this is possible.
This is the CRT in the machine:

Got this info from the Freeze Frame teardown video on youtube.
