Hello guys,
I recently came across this bootleg where it uses 8x V Rom, the connections are not clear from the picture and I was wondering if anyone in this forum is able to explain how to bank switch between V roms.
In the photo it seems to use Ls139 already present in the card.
I see that all E0 - Chip Enable pins are connected in series, and then another wire on the LS139's Address Inputs A0a.
Can anyone explain bank switching?
Thanks in advace
