A very special thank you to Alex Bodnar for the generous donations of the "Heathkit Digital Computer systems reference Manual" and the "Heathkit H37 Computer Computer Monitor." Both Items are on Display at the Museum.

This Reference manual is different from an assembly manual by including multiple software codes for multiple different models produced by Heath company. An assembly model is more focused on one model of computers and how to operate the computer. This reference manual includes Models: H8, Hc8-14, PAM-8, BUG-8, TED-8, HASL-8, and extended Benton Harbor Basic.
