The FM-77AV40SX was the last FM-77 series machine, Audio-Visual expansion of FM-77AV40EX.

About this computer, **Nomura Hisayuki** adds:\
Some people said FM77AV40SX was the ultimate 8 bit computer. (Other people said that Hitachi S1 was this one.)\
Its video-functions were remarkable.\
\- displays TV programs on it's video monitor,\
\- TV control from the keyboard,\
\- TV screen capture,\
\- displays subtitles on TV.\
These functions were realized in the 80s!\
260,000 color graphics was also marvelous.

The case colour which looked like the stone was beautiful. A lot of people called FM77AVSX a "tombstone". This PC was the last FM77 machine. So, FM77AV became a real tombstone of FM77.
