Quoted from cudabee:Why remove it, it is a pretty rare factory option? I know they existed but never seen one untill this.
With blown chips and a leaking cap, there's no reason to leave it in. Honestly, even if you fix those, you can't do much with it these days.
Quoted from zaza:Maybe coyote is still interested in a 2nd set ?

Appreciate the thought! The only thing worth a few buncks on the board would be the 8521 UART->Serial chip, and then 14411 (going from memory here) baud-rate divider chip.
ot worth paying shipping to get those, especially since I'm working on a side project to just hook up to the data lines using the parallel interface.
