That would be me that flipk is buying the board/chip from. I think it
might be important to note that for all discernable purposes the chip is
nothing more than a 133mhz 486. The whole naming scheme for the chip
(which is officially Am5x86(tm)-P75) seems to be just a marketing scheme
for AMD. All the digs on the chip can be seen here if you're curious:
