      Hi James,
      I think the problem is with the oscillator
      frequency. ML67Q500x series has a built-in PLL , which
      for an external oscillator can operate at 4x/8x
      speeds depending on CLKMODE selections (These are
      hardware connections). So if you have a 7.5 Mhz
      external osc. your cpu can operate at 7.5 X 8 = 60
      Mhz. Form your query it seems that u are a pretty
      older method for flash programing . Thankfully Oki
      has put up a useful IAP utility called OKI ISPF at its
      website which is much more handy.
