Eugene Dorr

Biographic Sketch:

Eugene Dorr is a retired computer programmer, whose first “computer” was an HP-65, back when it was introduced in 1974. His two passions are spaceflight and computers, so the ASTP HP-65 has been a natural interest. Most of the information in this article has been uncovered since his retirement. Some readers may be familiar with his Early Mission Patches website  (patches.genedorr.com).
