my friend is in the middle. now i look at this pic i see that my friends assistant seems to be enjoying herself immensely. i cant help but wonder if saint wasn't right after all ;)

here is the business end of it. my friend repairs, tunes and builds church organs, in australia that makes him genuinely about a one in a million person! this organ dates from the 1880's and these sorts of things are constantly upgraded. it originally had pneumatically operated valves but sometime in the early 20th century it received an electrical keyboard, valves operated by solenoids (except for a few really large ones which are still pneumatic).
even in the early days there was a way of 'preprogramming' the different stops on the left and right side. in 1984 it was completely restored which is what all the stuff i posted dates from. when you set a programme, all the stops move in and out to the correct position, a bit ghostly really. if it was a modern machine of course each switch would just light up rather than a solenoid move it in and out. wouldnt look as cool though (",) a lot of the electronics was about multiplexing certain pipes since this organ has approximately 2500 of them!
so my friend has almost finished replacing all the old electronics with much more modern stuff. you should see the wiring looms, some of them have nearly one hundred strands of data cable :o - makes our mame wiring look like nothing.
the new motherboard has an EPROM. the production volumn is so low that each motherboard is made to spec and the manual is specific to that church.
it was really cool that he let me have a look in. i even got to climb up inside it to photograph the internals. a site most tourists dont get to see (",)
and of course, since it is a musical instrument you can play 'tic,tac,toe' on it- albiet a tune of that name rather than the game. hey, i thought it was a clever clue!
