Tau Systems Synth Modules

[patchell]

    Got a question for you.  I was going through a lot of my "junk"
today, and found a couple of kits I purchased a loooong time ago
(invoice dated Nov 1977).  I have one of each of a TAU(sp?) VCO and TAU
VCF.  Is there anyplace where I can locate schematics for these?  The
filter apears to have been assembled (I don't even remember purchasing
these, let alone working on them), but the VCO is still a bag of parts.
It is posible that I may eventually find the docs, but who knows.  I
should have written the model numbers down, but they have a four digit
part number which are ??10 for the VCF and ??50 for the VCO.

    Any help would be appreciated.  Seems like a waste not to finally
complete them and put them in operation.  Thanks.
