Industrial Micro Systems produced S-100 boards in Orange County, CA, at least by 1977. Later they became IMS International, Carson City NV at least by Jan 1982. One manual I have from "L F Technologies of Carson City NV, is a Sept 1985 "S100+ System Install" manual which refers to many of the IMS International card model numbers. These are all the same company.
However, don't confuse ANY of these companies or the cards produced by them, with "IMS Associates Inc", later known as IMSAI. I have an IMSAI Web page.
In 2009 I came across this article from May 1988 associated with Computer Business Review. it says "Carson City, Nevada-based Cubix Corp, which under its previous name of L/F Technologies Inc...". The article which also says; "Cubix Corp recently acquired Los Angeles-based Intercontinental Micro Systems". However I list IMS docs on my "miscelaneous" S-100 documents page and seperately from the list of docs on this Web page.
I have a 2009 discussion with an IMS system owner on this linked Web page. Links on that page will take you to a Web page of links and discussions from other recent S-100 owners. Another Web page provides some IMS history from a former dealer, which clarifies the corporate history.
For other S-100 companies, check my miscelaneous S-100 docs list.
Price, email and other information can be found in this notice.
