Maplin modular kit/Digisound info reqd

[Rob Hukin]

I was just given a couple of old Maplin modules (2 VCO's, EG/VCA and a
mixer) with a load of junk a friend was throwing out. If anyone has info on
these modules they would be happy to copy for me it would save me a lot of
searching through old copies of ETI :-(

Also, while i'm at it, i'm renovating a Digisound 80 Modular for a friend
and we need circuit diagrams for any of the following; 

80-2 VCO
80-3 LFO
80-4 Mixer
80-5 Processor
80-6L VCF
80-7 State variable filter
80-10 EG
80-11 Dual ring mod
80-12 Noise generator and sample & hold
80-13 External input module
80-17 Reverberation unit
80-18A Dual EG

As possible trades we have a full user manual for the modules and AlphaDAC
and circuit diagrams for the 80-9 Dual VCA as well as circuits/article for
the AlphaDAC (we're still undecided as to whether it's worth getting this
beast working - feedback from anyone that's used one would be helpful
here).

thanks,
rob.
