<!-- 

  Note: info taken from Peter Hanraets's machine, with serial number 001267 .

  No pictures of the mobo were available, but it looks like

  the CX7, CX7M and YIS604 share the same motherboard.

  Such mobo has an S-3527.

  I'm not certain if this machine was delivered without SFG-05 and software module.

  But we can't seem to find another reason that this model is different than the

  CX7M/128. Still, Peter's machine did have the SFG-05, but not the software (FMV2).

  We'll assume it was built in later and this model didn't have the SFG-05, which seems

  to be consistent with the price difference (99000 Yen vs 129000 Yen).
