Besides the legacy Sinclair BASIC, the ROM included a word processor (Timeword), Timex Extended Basic (with support for the Tenet network, floppy disks and RAM drive) and a CP/M terminal emulator.

RAM was expanded to 256kb.

At least one prototype was built, but the machine never reached the market due to Timex of Portugal shutting down its production line before its release.{{Cite journal |last=Florindo |first=Bruno |title=CIRCE - AMERICAN COUSINS |url=http://www.armchairarcade.com/neo/files/Circe%20-%20Timex%20Computers.pdf |journal=Byte High No Limit |issue=22 |pages=64}}
