<A HREF="http://mbhp.coinoptech.com" TARGET="_blank">SmashTV</A> did a batch order and provides the PIC with preburned Bootloader and MIOS for an extremely fair price to the community (<B>$9.95 !!!</B> Compare it with stock listings under <A HREF="http://www.findchips.com">findchips.com</A> and you won't find cheaper offerings for single parts!)<BR>
