Alien Syndrome  by Sega
-----------------------

These are the EPROMs from the smaller daughter board of the arcade
game.  I do not have the rest of the motherboard, so I don't know if there
are other chips on that board that could be copied.

The files are labeled by the chip's location on the board.  There are two
columns of chips, labeled C and B, with rows 1 - 11.  My board doesn't have
a chip in C-4, and I don't think one was ever there...

The EPROMs are 27256s and 27C512s and they seem to be a mix of 200ns and 250ns.
