@katarakt
Glad to be at your service!

If you like them, spread the word!

[katarakt]

Yes for sure!

I have a question, is it normal that the PLAnktons are different ? There is a missing pin in the upper left corner and on some another missing pin (marked red in the picture) ...is this normal and have you verified that all are working ?

It's because we don't want to throw pin pieces away or piece together pin strip parts to fill all needed positions.

The 40 pin strips are divided into 14+13+4+9 and 14+13+13 so that two 40pin strips will cover three U17 PLAnktons. The circled pin is originally "Chip Enable" and is not used by the U17 PLAnkton, (as well as pin 1 which is Program Enable IIRC), it's optional. In the C64 it's grounded for constant chip enable signal. Where this optional pin is connected it is just connected to ground.

@Katarakt
Note there are 2 color spots on the Xilinx CPLD.

The bronze one on the left means the chip has been programmed.

The silver one on the right means the PLAnkton module has been fully tested.
