ABOUT very classic drummachine that introduced the chase light sequencer system! well known analogue sound with real programmable grooves after the quite hard-to-prog CR78, 1981 choose an instrument (with that dial upper left!) set the steps and measurement (tri and normal each of the 16 led/buttons replesent a note) the sound of each instrument can be adjusted (there are mods to expand the number of parameters for the 808, 606 909 etc...

Mr.Kikumoto (the man behind the 808,909 and 303) wasn't happy with the hand clap.
ABOUT Die Klassische Drummaschine, die das Lauflichtprinzip in die Welt brachte, in sehr vielen Produktionen zu hören!

Herr Kikumoto, der Entwickler (Tr909,808 und 303) ist nur nicht zufrieden mit der Handclap, so sagte er mal in einem Interview.

Changing the TR808 Switchboard..
TR808 opened..

here's the picture 808 tour..

for our american viewers: do not try this at home - only at YOUR OWN risk ;)

1) remove 3 screws on back and front

2) there are also some screws to remove at the left and right side..

3) now you can remove the control board from the PSU (mine has it's midi interface here also see picture, the big one to the right going to the upper board is going to the knob box! so maybe you do not have it! but maybe you can copy it - just click the pic..)

btw: you can enlarge almost ANY picture by clicking on them!!

4) now remove the knobs and another 3 srews in the middle: one under the big tempo knob, one above the "808"-lettering and another one beside / above the R of rhythm composer..

5) carefully remove the board and leave the cover as is, watch the cables!! the power switch must not be removed but be careful when turning the cover / removing the board..

6) when open: you can remove the screw holding the switchboard (right under the switchboard in the front..

7)now the one to be VERY careful: see the flat connection going to the switchboard? .. the 3rd picture shows it already removed: gently use 2 finges on both side to pull it out..

8) you can unsrew 3 more screws now on the board and remove it now.. the 6th pic shows how it looks like ;)

9) see the different boards awailable in the following pictures..

10) now place the board and fix all screws again..

11) how it looks like now.. the last pic and the small "movie"..
