RAM Micro RM16 - 80s mixer -schematic?

[NOON]

Hi everyone,
I've just dug out my old RAM Micro RM16 mixer from where it's been living in a friend's cupboard for quite a few years. I've pulled the back off and it looks like a good simple mechanical design and there are a few 5532s scattered around, which was rather fancy for a low end mixer of this era. You can read an original review from when it was released here. RAM Micro RM16 Mixer (Home & Studio Recording, Jun 1984)
What I can't find around is a schematic for it. Anyone got one hanging around? Wouldn't mind doing a resto and a few simple mods and using it as a general utility mixer in the studio.
Cheers

I didn't end up finding out anything else about this mixer but I did end up tracing out the circuit and making a bunch of modifications. Can't remember exactly what I did, it was a few years ago now. Here's the schematics I traced out, not neat, not complete, just enuogh to work out what was going on and do some mods.
