Some days ago I bought a used TI-89 (not the Titanium) and now I need a cable for connecting it to PC. The choice is between black serial and USB cable. I work mainly in WinXP and sometimes in Linux, so both will be good.
The question is are there any special advantages in each of them? For example will the black cable make possible connecting my TI to other RS-232 devices like digital multimeters. |

The black cable does not translate between RS-232 serial and the calculator's link protocol - the computer running the file transfer software has to implement the TI link protocol in software. This means that you would not be able to use the black cable to connect the calculator to standard serial devices without additional hardware. The old grey serial cable does, however, if you can find it - but I don't know how well supported it is with new file transfer programs.
I've always used the black cable (or a home-built compatible cable), never the USB (silver) cable, so can't really compare the two in any great detail. |

| Thank you for the response. I'll try to obtain both and try. I think they both are available on eBay. |

Yeah I use my Silverlink only because I could never aquire an other working cables, I have attempted to build a parallel cable multiple times but It never seems to work, even though I built it to spec, oh well  |

| I've probably mentioned it before, but remove the resistors from the parallel link cable if it doesn't work (short them out). No parallel port I've ever seen is able to drive the calculator's data lines low with those resistors in place. My cable works perfectly on all computers I've tried it on with the resistors removed. |

Yeah I have the resistors removed but it still doesn't seem to work. I'll have to double check I have every thing hooked up correctly and try again.
BTW, what linking program are you using with it I've had no luck with either tilp II for windows or linux. |

Yes, it works fine. It's the one I'm currently using. :)

TILP 2 here. What's your parallel port's base address? (You can find it in device manager; find the port, resources, I/O range). My port's base address is 0xCCD8, so I needed to patch TILP in a hex editor. :\ |
