I've got this turbo display out of my old Pentium 1 pc's case that I've never really got to work, mostly because I don't have any experience with turbo displays, and also didn't find any manual online.
It has a model number, BM-168.

So you think it's really good, yeah? You should try making the bloody thing up; it's a real pain in the arse.

See http://www.minuszerodegrees.net/led_speed_dis … eed_display.htm for a general discussion of LED speed displays. Your display is to be used with a turbo switch with two connections: One connection that goes to the mainboard and a second connection that goes to the middle three pins on the central pin row. The right two pins get a +5V supply, and the left two pins are to connect a turbo LED.

Well it is a BM-168 🤣. They are pretty generic. It looks like it follows the same standard as any 3 pole display where you have the ones and tens row with turbo/normal/both for each segment, and a small section for the 100's portion to turn the 1 on when in turbo mode.

L- and L+ are for the turbo LED.
TGN is for the 3 wire turbo switch (turbo, ground, normal).
Then you have G and +5V for power.

I will say one thing though.. These type of displays have segments die over time because they only use one resistor which causes too much current to go through certain segments depending on which are lit up.

I mean, I did warn you all that my knowledge is zero with turbo displays 🤣
But thanks for the advices, looks like I'll need to find other cables too, so I'm not sure when will i get this working (if it works that is). One day, thats for sure.
