I think the hardware from the equipment it's taken from might help or at least give hints how to use the lcd. |

Well i have the terminal where the lcd came from, the sad thing is the lcd controller is a hard one to find specs too. And the terminal was fabricated in 1989 i think ??? Even Texas Instruments doesn't remember it ... |

i have this display, i recovered it from an old vt-100 terminal made by texas instruments, the funny thing about it, they dont remember this model ??? CA and UL approved ??? . it is a 640x200 dots with a 1/200 duty cycle pins 1: FLM or (YD) frame signal 2: LP data latch signal 3: CP clock signal 4: M alternate signal for lcd drive 5: vadj contrast (-14 to -21v), -14v = nothing, -21v = all dark pixels 6: +5 volts 7: ground 8: VEE -21volts lcd drive supplys 9: XD0 10: XD1 11: XD2 12: XD3 13 to 18: not used 19 -20: optional backlight the frequencies mesured in the vt-100 terminal where : pin 1 = 77.63 hz (15.5265 / 200) pin 2 = 15.5265 khz pin 3 = 3.074 mhz pin 4 = 38.82 hz (77.63 / 2) im running this panel with a sed1335-32k from mpi web 2000 and two dc-32 converters from allelectronics. All wired to use a LPT port. But the refresh rate is very low, if i push it faster the display comes garbled. hope this help |

Aside from the SED noise, how does it look? I think I might have one of these laying around, just havent had time to play with it yet. |

i've played with it, it worked well in text mode, but it was so slooooooooow in refresh rates, the display couldn't clear the preceding characters or images fast enough, the following one just superposed themselves on top of the others, after a few sec's the display was full of junk ..... |
