My first computer was an Ohio Scientific C4P. I received it as "payment" for writing the documentation and collaborating with development of an early word-processing program, WP6502. I'm writing an autobiographical account of that time in 1980-81 and would like to use your photo of a C4, as I made the mistake of giving mine away a long time ago. My autobiog is strictly a non-profit venture so I hope you won't mind sharing your photo with me.
