=>"A" port of 82C55 record a "FF".
(4) It confirms whether or not output exactly come out as refer to specification Oscilloscope and JP1
connector.
(5) I/O address offset input "A4" Data input "0". After press I/O Write button, check the output od
Oscilloscope. It record "FF" of 82C55 A port.
(6) In the above test (3) ~ (4), you perform it to a port B/C.
