Description: A collection of information pertaining to Heath/Zenith & Heathkit. Mainly schematics but some other information that has been collected over the years. All of the schematics are fold out - the Heathkit Digital Computer H-89A is focused on and continues to give information on the 16K Memory Expansion Accessory, the CPU Board, Model WH88-16 schematic, a 1981 document for Secured Computer Systems & the Memory Expansion Card. The binder also contains information on Model A800 Disk Controller for Shugart SA800 & more schematics. Softstuff, a trademark of Heath Company, has a document in the binder about their CPS: Computerized Phone System. It would be easy to break down the documents and sell them individually but this is such a nice compilation that was worked really hard on and is in excellent condition (most articles date around 1980) so listing it for one buyer who will appreciate the work that was put into this binder is ideal. Please note all pages are hole punched in order to fit in the 3 ring binder but other than that there is no damage on the pages. Please check out the pictures and make an offer.
