It's for the SASI interface for the Kaypro 10's. The 10's used the same
motherboard.  There should be numerous empty spots on you motherboard
near the SASI connector -- those are for the logic to implement SASI.

It is possible to add these chips (soldering iron time) and then add
a hard drive, but you'll still need a Western Digital WD-1001-HDO or
WD-1001-005 controller to plug onto the SASI port.  Oh yeah, you'll
also need something called the "small circuit board", which plugs
between the SASI port and the WD board.  There is a company that 
advertises in Micro-Cornucopia that sells kits to add the SASI port,
the small circuit board, and even the WD controller.  This would
probably cost in the neighborhood of $225.  I can't remember the
name of the company, but their the same people who sell the KayPlus
ROM and they also sell QP/M from MicroCode Consulting.  

A cheaper way to add a hard drive would be to get one from Advanced
Engineering Concepts.  They even have a special version of the
Advent TurboROM that supports their disk controller (allows larger
drives and you can boot off the hard drive).
