These are the documents for the ETI/maplin documents I scanned if
anyone missed them from when they were posted onto Matrixsynth. The
ordering for the book is a little weird. I took staples out of the
book, and ran it through double sided through a sheet feeder. You can
then print it out double sided, fold it, staple it, and bam! you've
got a reproduction of the book.

 However, it just happens that the filter schematic is on the centre
page, which I've put into a separate image for y'all.

This PDF IS the full 3600 and 4600 manual which was available as a
book, for the princely sum of $12.50

 Peace out.....
