* '''Board: 27...?, MC...?, Copyright 1990'''
* Version without TV Modulator installed, and with IC101 replaced by 4 transistors(used in French models; where the PAL modulator would be useless).
* See [[Media:GX4000 12.jpg|this picture]] (might be same mainboard as above, not sure - the photo doesn't show the boards part number; hidden behind the cartridge slot, one thing that IS different is the K1 vs K3 text near the LED).
