Wei-ya 19" standard resolution (CGA) chassis:
# 820H High impedance vertical yoke, 29 mm neck diameter (a.k.a. 10 pin), requires isolation transformer
# 820S High impedance vertical yoke, 22.5 mm neck diameter (a.k.a. 8 pin), requires isolation transformer
# 1220H Low impedance vertical yoke, 29 mm neck diameter (a.k.a. 10 pin), requires isolation transformer
#1220S Low impedance vertical yoke, 22.5 mm neck diameter (a.k.a. 8 pin), requires isolation transformer
# 2820H High impedance vertical yoke, 29 mm neck diameter (a.k.a. 10 pin), does not need isolation transformer
# 2820S High impedance vertical yoke, 22.5 mm neck diameter, (a.k.a. 8 pin), does not need isolation transformer.
Medium resolution (EGA) 19" chassis:
# 1520H no other information available
All of the above chassis will have the wrong connectors for the American market. These will need to be "Americanized" in order to be plug n play with our wiring and connector standards as mentioned here:
