A4000D motherboards suffer from the following flaws that eventually pop up due to age:
- Leaky battery
- Leaky audio capacitors
- Extra-fragile simm sockets
To find a motherboard nowadays that doesn't at least suffer from one fault from the above mentioned ones is very difficult. :-(
Also, the chips on-board are mostly soldered to the board (except the roms and sometimes the buster chip), so if one goes bad you need to desolder it in order to repair it (e.g. like that CIA chip from a picture in the auction).
