I plan to make another version that uses the LM386 as the amplifier for a slightly more modern alternative.
That one will be black to differentiate them
Those will be sent of for fabrication soon along with several other utility boards
(male-male edge adapter)
And possibly a in/out parallel port based on the 8255 depending on how much I want to sleep tonight

I don't think I'll get around to the AY soundcard yet (have to save some fun for another weekend)
I tend to batch boards because shipping is more than the cost of making the PCBs these days.
The minimum order is also 5. So, I'll have spares of most everything.
Feel free to DM me if yone have a SP0256-AL2 and need a board.
Cheers,
Matthew
