A close friend of mine actually met Werner Buchholz while visiting a relative at a home states away where he eventually passed away. Its because of that i'm so familiar with Crumbs, Nibbles, and Bytes (he coined the term Byte)...theres a sad irony to that though, as he was supposedly chewing his food to practically bird mush and then eating it before he died a few months later.

(pun-intended, but not in a disrespectful way), I wish i had a chance to meet him myself...the things he could have explained--even at the end.
