128 Laser Clone Extender Card Kicad Project

I got asked if I could adapt a previous Apple ][e slot extender I designed, to act as a 128 Laser clone external slot extender. weel I had a bash during the UK heatwave afternoon siestas its public domain on GitHub.

I only have a Apple][e so can not test if I have got the circuits right any one who wants to get involved can find the Kicad 9 design files at

Link to design

More than happy to have extra design help and even better if UK based.

Thought Experiment

@sofwarejanitor,

Thanks for the kind words. It has been quite a learning process as I never even new of the 128 laser clone let alone the extender .

It  certainly changes a lot of the the lines on the extender socket when used in this mode.

It's free to use and abuse as long as everyone realises this has not been turned  into a PCB and tested for correct function. which is why I put a lot of selectors and contact points for testing.
