I am trying to repair FIC KC19+motherboards ( https://theretroweb.com/motherboards/s/fic-kc19-hp-oem ). Some stupid guy ripped out the transistors which are mounted between paralell port and slot 1 (these with radiators) and also smached some surface mounted elements. I have 3 of these boards so I found the parameters of surface mounted capacitors and resistors but I need informations about the type of transistors Q4 and Q5.
I have also FIC VB-609 ( https://theretroweb.com/motherboards/s/fic-vb-609-oem ) with FDP7030L and IRL3103 transistors. This part of motherboard where they are mounted looks similar to KC19+. If I will not get any informations which type of transistors were mounted on KC19+ I will use these from VB-609. I know that it is not a good idea but what else can I do?
Please help me to restore FIC KC19+ motherboards. They are interesting for me because they are using RAMBUS memory which is not so common on slot 1 motherboards.
