I am just fixing the formatting should be done by end of the day.
Geoff A. Bobker did a ton of work but seems to have been a bit of a fringe figure, none of his stuff get's much exposure either back in the day or now. It seems kinda weird as this fella did everything - he wrote applications, developed and marketed hardware peripherals and published a newsletter/book.
And this fellow seems to be a ghost, there is no information beyond a few references on WOS related to the guys output - but its not like this stuff was reviewed except for a few cases.
One of the big questions I had when I began all this was 'what would people who wanted to create professional level applications/games/hardware get the information to do this.' and his stuff had to have been a source.
Edit: This is gold. Read 'Feet of clay'
