Need some help with VFD
They are 1 x 16 starburst displays, they have all 5 pins and are probably serial devices.
One is labeled 'PULSEVIEW LTD' with partnr PV0176-001-F Issue C and has 2 OKI ic's on the back.
The second one has as partnumber 31-487-001 ISS 1 and has a NEC D7538AC IC on the back.
The third one has as partnumber 31-711-001 iss 2 and has a NEC D8042GF-090 IC on the back.
Has anyone some info about them because google didn't help me out a lot? Pinouts and commands are most welcome.
