Tak si nemuzu pomoct, ale tyhlety problemy se dost prodrazi.
Jak dlouho asi bude trvat, nez lidi pochopi, ze Intel je
rychly, ale nespolehlivy. Ted uz je asi vsem jasne, proc
Motorola kazdy novy CPU testuje tak dlouho a proc na nej
tiskne MC az po nekolika desitkach tisicich prodanych kusech.
Vsimli jste si, ze 060 jsou stale jeste XC?

Jinak z vyse uvedeneho jasne vyplyva, proce se Mototoroly
pouzivaji pro rizeni procesu a ruznych jinych dulezitych
veci jako napr. TGV. Tak me napadlo, co pouzivaji za compy
v raketoplanu od NASA a zeptal jsem se. Odpoved jeste neprisla,
ale na palube pouzivaji obycejny Thinkpad od IBM a stale
s nema maji problemy. Naposledy stratili kompletni data
s jednoho experimentu, ktery se delal pri pristani na MIRu.
