A - 74LS02
B - 74LS86
C - 74LS08
D - 74LS138
E - 74LS133
F - 74LS279
G - HN462732G EPROM, Label with GPC on it
H - 74LS244
I - 74LS374
Bar between H+I is an "A102J" resistor pack (1kohm?)
The header is next to I, right angle (pins parallel to board)
Two rows of pins, total of 26 pins.
SW is a 4-position SPST dip switch
