I need a copy of these - does anyone have them in their files? Prefer 11 X 17 in. copies. I have the CTS-1 cable for the board and can power it up, but there is a weird RAM select issue that I can't resolve using the Atari SP-218 schematics as they do not document everything! They miss the connection between the Sound CPU and the Data Buss DB0 - DB15. It turns out that DB0 - DB7 is hardwired to SD0 - SD7, but how the Sound CPU access DB8 - DB15 is not shown and yet the ram associated with those data lines ARE available to the Sound CPU. Must be some sort of latch hiding there somewhere! Thanks!
