There appears to be a parallel port dongle for almost every remotely popular synthesizer chip nowadays, but I have not seen anything based on the AY-3-8910 series, yet.
Is there nothing we can do about that?
Surely we could build a hypothetical AY-LPT just like an OPL2LPT, OPL3LPT, TNDLPT, CMSLPT, SID LPT or whatnot and put everything in a 3D-printed case, but as a wise person once put it: "Good engineering is cheap engineering."
So how exactly can we make the thing cheaper?
It occurred to me that if you solder the PCB to the DB25 connector in a slightly unorthodox way, a socketed 24-pin DIP chip like the AY-3-8913 can be squeezed into an ordinary adapter case.
This is the mockup I threw together for illustration purposes:
There would have to be one wire for GND, but everything else on the second row of the DB25 connector is not really needed.
The device would need power (preferably regulated 5V via USB), an audio output jack (preferably stereo) and maybe a volume wheel.
The front panel could be either printed cardboard (cheap) or maybe a thin PCB (premium).
Internally, there would have to be at least an SMD crystal oscillator and a couple of SMD resistors.
These are the configurations I can think of:
- Unbuffered line-level output
- Buffered line-level output
- Amplified output with volume control
What are your thoughts?
