zip1 Collette Utilities Documentation [GEOS]

Collette Utilities is a collection of GEOS programs and Desk Accessories for the Commodore 64 & 128 by Jim Collette.  Programs in this collection will run in both 40 & 80 column mode.

The cool thing about this updated documentation, by Bruce Thomas [November 2022], is that it's completely laid out and generated from geoPublish! The PDF is formatted to print double-sided with room for hole-punching for insertion into a binder or duo-tang. There a couple of blank pages intentionally.

Just for comparison, here is a link to the old documentation we had, what a difference!  Thank you Bruce for cleaning this up and sharing.

Here's a link to the actual GEOS Collette utilities disk images.

zip5 GEOS Tips & Tricks

The information printed in the magazines as "absolute know-how" was often nothing more than superficial repetitions of passages from the manual, or even half-truths or less.  After a while we had our fill of this sort of reporting, and we decided to write a book of our own that on one hand cleared up the half-truths, and on the other hand presented the many tips and tricks that we had picked up in our work with GEOS.
