Chip on left is a -003 but doesn't seem to be a classic EPROM where chip on right is -002 and is clearly an EPROM. Odd right? The chip on the left looks like a masked ROM and can not be reprogrammed. The chip on the right is like I have seen in all drives so far a 2732A Texas Instruments EPROM Quote Link to comment Share on other sites More sharing options...
