Does the display show anything with the current jumper arrangement?

I just fiddle with them until I understand how the jumpers work and then set them as required, i.e. just trial and error. I've never damaged them in doing this.

Exactly this.

Hello
It shows 20 in turbo mode and 16 without turbo.

Hello
It seems that's the only option I have left. I have a 286 and a 386 with a display, for which I found the manual, and the configuration was easier for me. Now it's just trial and error.
Thanks.

Deploying logic, 20 and 16.
0 uses 6 out of 7 segments, there are 6 use on the bottom right 7, the missing one is probably the centre crossbar
6 uses 5 segments, there are 5 on the bottom left 7
1 uses 2 segments, and 2 uses 5, breaks down a little but looks like top left might be the 1 and top right might be the 2

My WAG:

1 a
2f b
3 g
4e c
5 d

[just editing to add that as you're testing to make sure you always have a few LEDs lit. If there's just one lit then the current through that LED can be a bit high and it might be damaged]
