    If I traced the circuit for this device, say onto or please suggest other sites, would someone be willing to produce a PCB design from there? Perhaps with an 8 pin DIN pcb mounted jack instead of the flying lead?

    No promises on when though, I am exceptionally time poor this year......then again it’s a simple PCB perhaps sooner rather than later.

    The NEC D8039LC datasheet is here:

    It appears to still be available, or at least available enough on eBay etc to satisfy Tandy 1000 owners wanting a keyboard adaptor.
