This is another enhanced version of the original [PC-6001](/museum/nec-pc-6001/) and later [PC-6001 MK2](/museum/nec-pc-6001-mk-2/).

Two Basics languages (N66 & N66SR) are built-in. The computer is still compatible with the N60-Basic and N60-Extended Basic modes from the original PC-6001. The Basic N66 offers a 320x200 graphic mode (in 4 colors) and the new N66SR-Basic offers new text and graphic resolutions, the maximum being 640x200 with 15 colors.

There is a ROM holding 1024 chinese characters. The PC-6001 MK2 SR offers optional speech synthesis features.

There were 2 floppy disk drive types that were incompatible with each other, known as B and BE.
