The Siamese transfered data to the PC via a real cable. Today I found a serial cable labeled PC on one end and amigaon the other. I think this is what I used to connect the two but I can't remember. I have more Amiga stuff in my storage space but have a hard time getting there as it's in the boondocks.
I eventually did the ZIP drive thing on PC and Amiga eliminatd the need for this. This card lived in my old A3000T. ahhhh memories.
