The Raven has 32K RAM, of which 20K is required to implement shadow RAM. This board only has 16K so not enough for shadow RAM. You should try to write to all sideways ROM banks and see which can be read back to confirm. I suspect the jumper J1 will select which sideways bank is RAM.The hardware looks not too dissimilar to the Raven??? Ram board. I wonder if it could easily be used as general SRAM?
