I'm working on a Flight 2000 MPU200. I'm only getting two flashes. I suspect one of the 5101's is bad (U8 or U13). I have several 5101's but I can't find two that match. I also have some new 5101 NVRAMs. Can I replace the 5101's (U8 and U13) with two new 5101 NVRAMs?
The board was repaired a few years ago. The corrosion was cleaned off and a remote battery was installed. So I'm pretty sure the board is fine.
