If I am not mistaken, the jumper is located between the 2 CIA chips. These chips are located under the power supply back by the external connectors on the rear of the the motherboard.

looking from the front it's just to the left of the PSU.

There is another jumper between the CIAs too by the way (206, with 3 pins).

Sorry, I was trying to remember looking at a pic of a Motherboard on The Big Book site.

Any chance you know which is the odd and even CIA chip?  My donor A500+ is nicely labelled ... but not the A2000.

EDIT: scratch that, it's just left and right on both (I figured they're only 2 side 1 layer boards, so would need roughtly the same track paths on a shematic level ... ok it's late and I'm babling now :-)).

I found it, thanks people. Bytheway did also manage to burn one floppy drive, did connect the power wrong... then a strange smell.. tadaa... huh.. got 3 more floppy drives so no problem .
