I picked up an 8' 2.5mil plug to 9-pin (Serial) connector cable assy hoping to add the necessary diodes and resistors to use it to connect my TI-83 Graphic Calculator to my LT. For anyone else that wants these simple schems and SW - contact me
Anyway, when I popped open the shell, I found a surprise. Soldered to the 9 serial-end pins was a small double-sided PBC populated with 3 SMD Transistors, 5 resistors and 5 diodes on one side. I'll send the macro set of pics to anyone that wants them as I could not figure out how to attach them here.
This device looks to me like it might be 'special' - Heck... to me anything with parts soldered on is 'special'.. so I'd rather not trash it. I'll get another cable assy to modify, but in the meantime I'd really like to know what this is and does.
Any help or insight appreciated.
