Hi,
Looking for switch setting info for the serial (multi interface?) board
in a Facit 4070 tape punch. The stencilled on labels are a little
cryptic, and there's no stencil for the big chrome toggle switch on the
back.
This is clearly not the same serial interface that i have in one of my
Facits. Mine has no switches (just soldered jumpers) and half the PCB
etch is text explaining how to set them (!).
Can you give the labels on the switches on your board? And what are the
main chips on it (is it a 1602/6402 type of UART, or a
microprocessor-based circuit, or what?)
