This may indicate that the '86 GIME has memory refresh problems in 
certain modes. The stability of 512K upgrades could then be a critical 
factor.

If an alteration of the add on memory boards is a critical factor, that 
needs to be identified. However, in the meantime most users with this 
problem should stick to a 32 col screen during the boot.
