Hello everyone, i have two rs232 broken.. one is ti and one is Corcomp. All two present equal problem.. when i insert in PE Box the Ti99 light on but go in crash.. no video present.. only light blue color on screen.. I for test i check many component on board and discovered that if i leave IC 74ls125 the TI99 start at working.. (obvious the cards no work). If i understood well seem that the signal extint stop the autostart dsr card on PEbox and crashed all.. any idea for solve this problem??
