 Memory card for SC-3000/SG-1000

I'm working on this memory board.
It's able "see" 8/16/32kb on entire Z80 address space. Dahjee Type A/B and Colecovision mode supported. Capable to enable/disable internal ram when the board ram don't overlap. I'm already studying if that GAL is enough or I need to switch to a CPLD. Enjoy. https://www.facebook.com/groups/sc3000/permalink/4159511594137858/?app=fbl https://www.facebook.com/groups/sc3000/permalink/4160681614020856/?app=fbl |
