I first thought about that, but there are clearly only two rows of pins,
and, as you say, the SE slot has three of them. If you look more
closely, in the area above the 68030 and 68882 with the four DIP chips
(two 74646, and two unknown ones, maybe PALs), you can see the legs of a
large DIP-64 socket, maybe a male one to fit in place of the Mac Plus'
68000 CPU. If it were an SE slot accelerator, the socket wouldn't be
needed. So I think it is a Mac Plus accelerator.
Sincerely,
Antonio Rodríguez
