If you have a smartphone or tablet, there are apps (lots of 'em) that show you any scale you want to see in any key, over the entire fretboard or position by position if you prefer. Minor pentatonic, major pentatonic, major, modes, all sorts of stuff.
And I'm sure you know this, but the minor pentatonic is the same on acoustic as on electric. You seemed concerned that everything is geared to electric, but when it comes to chords and scales, it doesn't matter...
