This is a pdf copy of the instruction manual for the Toyota 8600 machine.
Although the original that the copy was made from was a bit tatty in places, the illustrations are quite legible and I have retyped most of the text and the letters and numbers on the diagrams. It is therefore a usable manual. This is not an easy one to find so this was the only alternative to be able to make it available.
This manual is also available as a printed copy.
