In looking around eBay today, I found an Auction for a Firmware Card from "Software Dimensions, Inc". ( see attached picture )
Further Searching located the this info at Worldcat:
Accounting plus general accounting system reference manual .
Author: Software Dimensions Inc.
Publisher: Citrus Heights, CA : Software Dimensions, Inc., ©1981.
Edition/Format: Book : English
And this Info from Usenet, at Mac GUI:
So in Weaving all the Threads Together, it appears that the Firmware Card is a Hardware Protection device for a General Accounting System made by Software Dimensions Inc., who was Acquired by ASK Corporation, who was then Acquired by Computer Associates.
As an interesting note, the Firmware Card on eBay is located in Citrus Heights, California, United States, which is where Software Dimensions Inc. was located.. I wonder if someone was cleaning out there closet?
