Hey,
I got one not used in 20 years and it worked but glass top in bits,
barely working, could make out game on screen.
Rebuilt it:
Sand blasted legs, lots rust,
repainted metal parts,
Redone a Control panel, basic but chrome LEDs.
But PC and 14 inch monitor inside, running Mame.
But is PC 14 inch monitors fitted in fine for me. Could use existing brackets.
Piece de resistance, mirror glass Table Top.
When machine is off, cannot see screen,
power it on and screens light aloud pass thru mirrored top and like hidden screen.
Makes it old and modern in one go

Small video here:
Hope this helps
