The chip that is used on Cobbleware.com is a VDATA 16MX16-SDRAM CHIP
The micron chip is compatible ... because it is also 16MX16-SDRAM However, the Micron chip is faster becasue it is CAS LATENCY 2 ... and the VDATA Chip is CAS LATENCY 3
The Micron Number you need is: MT48LC16M16A2TG-75 this is the CAS LATENCY 3 part number.
Hope this helps.
