ITT we post PC-88 art
The PC-88 was an 8 bit Z80 based computer released by NEC in 1981.
While popular in it's heydey in the mid 80s, it is not as well remembered as it's successor series, the PC-98.
Because the computer was originally limited to a fixed 8 color palette, most art features heavy dithering.
