we can just generate sync from say PIC based sync code

and run straight into voltage dividers to VGA connector as below
FPGA switches itself
concurrent exposed communicative (promiscuous) (instruction?) modules
exposed by way of PWM or rather single bits which can then be output as audio or as video / composite (with sync generation in software - we have an NTSC example but colour PAL is more complex - also using small resistor ladder to output) or VGA (we have vgahdl example code which looks quite simple)
