A 2Mb SRAM hat board for the rosco_m68k SBC.
Fixed J6 routing. Added PLD code. Fix small spacing issues between J6 and the RAM sockets. Going to fab at end Feb 2024 .. and it works !
With patch to J6, this version works ! 4 layer PCB with proper ground and power planes.
Routes traces on all four layers of the board and was sent to jclpcb on 9th Feb 2024. Really not sure if this will work - my first pcb! Errors in CE and CE#, RW and WR mixed up. Not possible to use!
