The NES/Famicom is 1983 technology.
Indeed, NES/Famicom is 1983 technology. I might even take it a step further than that (while not disagreeing with you at all) and say that NES/Famicom is... "early 80s technology". Certainly the NES/Famicom was not just R&D'd in 1983, but probably 1981-1982, and released in 1983 (1985 in the U.S. as the NES).
The PC-Engine / TurboGrafx-16 is, at the latest, 1987 technology, at least. Yet was probably developed during the mid 80s.
The Atari Lynx: was released in late 1989, yet was certainly not 1989 technology. It was developed by Epyx by 1987. The idea came for it in 1985, and by 1987 the hardware was, at least in some form, almost done. Atari took it over, released it in 1989.
The Super Famicom/SNES: released in 1990/1991, but was shown as far back as late 1988. Nintendo changed the specs several times between 1988 and 1990. It would be most fair to say it's 1989 technology.
The Dreamcast: released in 1998/1999, yet was mainly developed during 1997 in the internal Sega competition with two consoles in development at the same time: the SoA-developed, 3Dfx-based Dural/Shark/Black Belt and the SoJ-developed, PowerVR2-based Katana/Dreamcast.
It would be fair to say Dreamcast is 1997-1998 technology since the hardware was completed in sometime between late 1997 and early 1998.
The GameCube: was released in 2001, yet does not exactly qualify as 2001 technology since it was actually developed during the late 90s, completed in 2000, before being released. It would be most fair to call GameCube as being 2000 technology.
PlayStation3: released in late 2006. The CELL processor was developed between 2000 and 2005. The RSX GPU being based on Nvidia NV47 / G70 (GeForce 7800), was released for PCs in mid 2005. It would be most fair to say PS3 is 2005 technology.
I could give many more examples, but, that's enough I think
