Wyse 520 Terminal

Pictures

Notes:

• The firmware is dated 1994 on this model.
• This particular model monitor tube is subject to screen burn. A blank screen saver triggered by an inactivity timer helps reduce burn risks.
• It is also subject to halt/freeze problems when the electronics are cold. I leave it always on.
• You can use either 6 wires DEC MMJ (offset tab) connector or standard 6 wires RJ (center tab) in PORT1/PORT2/PRINTER.
