​almost, that one has 6 outputs you need one with 10 outputs​
Thought the C64 user port only had an 8-bit port. Where are the other two connected? The VIC has a few of the joystick port connected to the user port, but not sure what other outputs you can get out of the C64.
There's a zillion different ways to demultiplex parallel I/O lines. A degenerate case (but a valid one) is an I2C I/O expander, some of which can give you 32 I/O lines from just two. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
