The TinyCAD Schematics
Here are the TinyCAD schematics. By typing all of the original schematics into TinyCAD, TinyCAD could generate a "netlist" of all of the connections between each IC or compoenent, to assist with laying out the traces in the FreePCB program. I include them because they are accurate, readable, and tested copy of the circuit, and do resolve a few ambiguities on the original schematics, such as the two clock signals.
To see the huge full-size/full-resolution schematics, right click the schematic, and and open image in new window, or download it.
