The Yamaha TX81Z, circa 1986:
Big transformer, linear regulators, two-sided board, bunch of DIPs.
Looks like the power switch is on the left at the back, and they've routed some long piece of metal around the regulator heatsinks all the way to the front panel. Anyone know why they'd do that?
The ICs seem scattered all over with not a lot of rhyme or reason to their positioning - make room for all the jumpers?
