Apparently "Industrial Micro Systems" became "IMS International" sometime between 1979 and 1982. I believe IMS also offered boards under the name of "LF Technology" or "L/F Technology". Do not confuse this company with IMSAI or IMS Associates Inc., which I have on an IMSAI Web page.
For other companies with similar names, check my
miscelaneous S-100 docs list.
Price and other information can be found in this notice.
