It's a really wacky IC. It's a 68 pin package.

Looks kinda like this

 | | | | | | | | | | | | | | | | | | | | | | | |
+-----------------------------------------------+
| +----------+ |
| +-----+ | | |
| | | R | | |
| +-----+ | | |
| +----------+ |
+-----------------------------------------------+
 | | | | | | | | | | | | | | | | | | | | | | | |

Both the boxes are ceramic squares (grey ceramic, like an eprom or
something). The little R looks like a surface mount resistor or cap. The
bigger ceramic square has:

SMS300-1
0002624
001 A 7620 on it

The field of the chip is white with grey zebra stripe lines running to
each of the pins. On the top of the IC is screened:

00020730001C

In gold and on the bottom:

SMS INC 2075-0001

In black.

What the heck is this thing?!?!? I know it's probably an engineering
sample, but of what?
