Filling a via with solder will drop the resistance about %40, and putting a wire in the via will drop it about another %40.

An 8 bit TTL computer made from only 10 chips and an EEPROM. There are two registers (A and B) and a PC. Amazingly enough, it can do useful work with only 2 instructions: MNZ will copy data from source to destination only if A register is not zero. ADD will add source and A register then store the result in destination.

Thanks also. I found, however, that the address is 8-bits too short for, say 24C64 which requires a 16-bit address. Since I was also using the USART (PIC16F628) I moved the SDA and SCL to R3 and R4 which requires 4 additional line changes to the code. Other than that - great stuff!
