[Coco] 28SF040 EEPROM + GQ-4X

[chadbh74]

   Since the 28SF040 512K chip is one supported on my new EEPROM boards
   and some of us may have the GQ-4X programmer, I thought I would ask
   here if anyone may have any experience with getting these two to work
   together.  I tried manually adding it in to the devices.text
   configuration without success.  I followed up on a old MCUMall forum
   post about this chip here ...

   If anyone has gotten it to work on their GQ-4x in the past I would love
   too hear how.

   Today I opened up a RMA ticket with MCUMall and sent them one of the
   chips so they could 'tune the algorithms' as they put it.  Hopefully
   there will be an update for this chip.
