Where the battery-area parts sit on the System 80 CPU board
On the kit's layout drawing the battery sits low on the board, with crystal Y1 just below-right of it, Z2 to its right and Z3 in the corner below Z2; R3, R4 and R5 sit beside Y1. To the left of the battery are Q1-Q4, VR1, CR33-CR35, C1, C36 and the resistor column R43-R50, with Z1, Z4 and Z36 further left under the 6502 (U1). The four DIP switch banks SW1 (lowest, nearest the battery) to SW4 stand in a column on the right, each with its eight diodes beside it (CR1-CR8 next to SW1), and R34-R41 just left of SW1.
