I have this model, HVC CPU NPC 18-01 , but not the normal MK 5060 conversion chip, this one has a chip GA030A , i wondering  is the  chip replaced before but the shields look untouched. So is that possible they just use the chip randomly from different suppliers.

Can't see much in your photos. What's the serial number, and the code on the shield sticker?

Newer units have a shield that covers the top, so I can't confirm the chip used. Maybe GA030A was used before MK5060.
