Single bus keyboard stripboard layout

[okelk]

rather old topic, but I ask anyhow....

Do you think it's possible to omit the (rather complicated) current regulator around the 3900 and replace it with a lm334?

it would need only 2 components instead of 10....

Does anyone have a wiring diagram for the control panel and or a control panel layout for the single bus keyboard (the old one, with lm13900)?? I try to design one using the schematics as a guide but..my mind doesn't speak that language yet ;(

Thanks in advance!
