High Quality Content by WIKIPEDIA articles! The IMSAI Series Two is a personal computer which combines modern hardware with the original IMSAI 8080 hardware and case, with the original front panel LEDs and switches. The Series Two supports USB and Ethernet and is a co-operative development from Howard Harte (Harte Technologies LLC.) and Thomas Fischer (Fischer-Freitas Company). It has no relation to the original IMS Associates, Inc. (later known as IMSAI Manufacturing Corporation) which produced the IMSAI 8080 during the 1970s.
