Help ID odd card..

[rkneusel@carroll1.cc.edu (Ron Kneusel)]

 We recently acquired and old Apple IIe and the card sitting in
 slot seven presently defies identification.

 It is a long card made by Apple Computer. It has a cable running
 to a female RS-232 25-pin connector.  There are no markings on
 the card (other than that it was assembled in Singapore) that
 indicate it's purpose.  There are many small chips, a larger chip
 with "Apple Copr 1989" on it, and two square chips in sockets
 with many pins each.

 Could this be a hard disk interface? SCSI perhaps?  With it in
 the machine there is a _long_ pause between turning it on and
 when the old Disk ][ drives kick in.  There is no pause with it
 out of the machine.

 If it is a SCSI card, how do we use it with our existing SCSI
 externals for the Macintosh?
