my problem : I want to add these machine too :
CD32+FMV+SX1
CDTV (optional)
Videopac G7400+
Atari 7800
Philips MSX2 (optional).
Texas Ti99-4/A (optional).
Atari 800XL (optional).

And these also if I can transform the output in RGB or composite (for antenna models)
Intellivision + IntelliVoice + CPU module
Nec PCEngine DUO
Arcadia 2100
ITMC SD 90 - 'Pong' clone that use "PC-500" cartridge

Is there a Tetris fan that can help me to optimize the space ?

PS : Try to find which of the pictured machine doesn't have an RGB output :hammer:

@Zac67 : yes I can , because the A1000 was an excellent game machine (on right you can see a 2mb fast ram expansion)
