, how can I translate the following into bin or hex files:

10 Print "10"
20 Print "20"
30 Print "30"
40 End

with a 51 basic compiler

I really wanted to know how to program the 28C64 using my micro-controller board.

You mix 2 uses of the word "program".
You make (write/compile/assemble/link) a program on your PC, then you program the PROM with that program
