Hi

I'm looking for DX 100 font found in the picture.

Thanks!!

Eurostile Bold Extended #2  Suggested by Colorbean 

I think the whole collection of Yamaha's old synths is using Eurostile with different weights.
For example, the Yamaha "TX 802" logo seems to be Eurostile Bold Extended (Eurostile Bold Extended Outlined for the numbers).

I think that the "DX" was written with Eurostile then modified to put the D and the X together after. That "D" seems not to be included in Eurostile.

Maybe, yes.
Thank you!
