No.  Green is one of the random colors that can come up.

This DOES mean something is dead.  In a former life I designed and
manufactured 256K ram cards.  This behavior with a newly manufactured
ram card meant that yet *another* of the PC boards had a short from
ground an address or data line.
Offhand I'd guess this means "chip memory test bad" and the number of
blinks represents a memory address.

I'd STILL like CATS to post a complete description of the powerup
disgnostics (Color flash, light blink, sound test etc.).
