This was a homemade Zorro slot I made for the Amiga 500. I followed a guide from Aminet. There is no logic here, it is just pins connected from the 86 pin A500 side slot to the Zorro edge card slot. Back then I did not have a source for Zorro slots so I made it myself by cutting up two ISA slots and bondoing/gluing them together. Did I mention that I did not have a desoldering gun so I cut a square around each pin of the ISA slot with a Dremel and removed them while heating the leg. This took more than 4 hours.

I actually got it to work with a 2MB Zorro 2 card. But I never got to be able to test any other card.

Later I got this more professional looking Amiga Zorro 2 slot adapter (but I never used it before selling it a couple of years later).
