It has nothing to do with Blizzard or not, but wether the RAM is configured
in Zorro2-space (below 16mb) or above it.
RAM-cards without a owns CPU will allways fall in the 1st category,as
the 68EC20 used in the A1200 has only 24address-lines (~16mb).
Cards which allow more than 8mb will allways fall in the 2nd as the Z2-space
is only 8mb wide.
Cards with own CPU but a max RAM of <=8mb may fall in both. Perfect
exmaple is the "Blizzard-turbo-mem" with a 68020 (or was that an EC ??)
at 28mhz.
