The "gray" case is the original design case. For what ever reason, it turned
out to be a problem for at least one intended application. The final design
case flipped the board over to take care of what ever problem the original
orientation created.

Does any one know about a gray cased Thunderbolt?  This unit is 
backwards from the gold box T-Bolt.  The circuit card is mounted on the 
non-flanged case half (that has the connector cutouts).  There is no 
serial number sticker, but does have the power supply sticker next to 
the connector.  And just for fun, the power connector is backwards from 
the gold box units.  You can guess the next line...
Does anyone need a T Bolt Aroma Therapy device?  One scent (not 
pleasant), slightly used, real cheap.

I was rearranging the bench and plugged a properly keyed power supply 
into the gray box.  The power supply that I did have on this unit 
doesn't have the keying lock.  Of course, this one has (had) the good 
DS1620 (D rev) chip.

Oh well, live and learn.
