Hi, i wonder what is this thing i have and what it does.
I need a box for a stepper motor controller but before i dismantle this thing, someone could tell me if this is worth something or its just trash.
Thanks.

"The ESI-2679B is basically an externally powered smart port. It
connects to a PostScript printer via either a parallel or a serial
connection (with Macs, a serial connection is recommended), and
recieves data through its serial, parallel and AppleTalk ports."  Sounds worthless in today's world.

ok, thanks for the info, it is a really nice case for my controller. 
If anyone would be interested in the board as it has z80 cpu's i could trade it for anything. thanks.
