AT&T Unix PC Expansion Cards

I just received a lot of AT&T Unix PC Cards from a friend who used to work at AT&T at the time these were introduced.  I have alot of the orginial media for these (and had wondered what happend to the cards).  

In the lot are the following:

• AT&T Speech Processor (sn-0174)
• Memory Card - part number: D-43-00219-00
• Memory Card - part number: D-43-00219-01
• Memory Card - part number: D-43-00219-01 rev C
• Memory Card - part number: D-43-00226-00 rev A
• EIA/Ram Combo Card - part number: D-043-00221-00 rev A (2 RS232 ports)

• Tape Drive Interface - 60-00234-00 (parallel port)
• DOS 73 unix coprocessor - Alloy Computer Products
