Jaleco ‘JK-03’ reproduction successfully tested

Some time ago I made a reproduction of the Jaleco ‘JK-03’ custom SIL used for inputs handling on some Mega System 1 PCBs but at that time I was not able to test it due to the lack of a proper PCB hence I asked for some volunteers.You can read the post here:

Seibu ‘UEC-01’ – ‘UEC-02’ and Jaleco ‘JK-03’ reproduction

Today I can report the reproduction is fully working thanks to the test carried out from the user ‘Astro X’ of AP forums on his Saint Dragon PCB with missing ‘JK-03’ (actually an hack was installed as workaround) :

Thanks again to him for the feedback.
