Hi and Welcome!
A good start is the following pdf:
https://devsaurus.github.io/mcs-48/mcs-48.pdf
It starts with a lot of information on the used CPU 8048 (or MCS-48)
From page 51 there is information on the 8245 video chip used in the Videopac
Also this:

Most of the 'Homebrewers' use an emulator to develop their code.
If it looks OK in the emulator then you can try it on the real hardware by using a RAM/FLASH/EPROM or EEPROM cart, or a multicart.
You can search the forum for things like: homebrew, ram cart, multicart etc.

A late reply, but I've been learning assembler on the 8048 and videopac and I can recommend soldering up a G7000 ramcart. Transfer your program then, flip a switch, reset and theres the program running.
