Never had a problem with any of them, ever. f3x171-10, but they are hard to find these days though they were very cheap for a while. To use with Model T, you need to have a db-25 gender changer.
But generally, you need a full-null cable. I wouldn't go with 3 wire cables since you may want to experiment with hardware flow control (HTERM, my bare bones / dumb terminal to Linux) given that you hook to Linux which overruns the Model T 64-byte serial buffer when using software flow control. Also Linux utilities throw in UTF-8 and lots of formatting codes. HTERM maps to/from utf-8 and strips ANSI color escapes, stuff like that. One thing to be aware of is some cables bump into the Model100 case and keep it from mating properly. You may have to shave some off the housing to make it fit, or ideally find one that fits into the space available, after adding the thin-hood gender changer. USB on the PC side is fine. I recommend only devices with FTDI chipsets, however (not Prolific). The FTDI drivers generally allow more configurability which ends up being necessary with TS-DOS (TS-DOS loves to time-out... remember USB serial devices have a tendency to delay/collect bytes to "efficiently" send a larger packet). -- John.
