I took the info of using the TPIC6B595 and failed to realize that it in itself would not work.
My solutions are remove the sockets for the TPIC6B59's and replace with a 24pin? socket for the MAX7219.
Another though I had was install 32 pnp transistors connected to the TPIC6B595 shift registers and add more connections to the already jumbled mess of wires.
Perhaps the easiest solution is put some 74hc595 shift registers in place of the TPIC6B595 and leave the resistors and 2803 as is.
While not the best fix but the easiest one IMO so I could leave most if not all the present wiring in place except make a few changes on the shift register / pic connections.
As for using info from the 8 x 8 matrix project. I plan to use basically the same code but include the shift.bas.
