A nevite nekdo, jaka zaznamova media se pouzivaji v raketoplanech? Tam ty extremni podminky nastavaji take (predevsim pretizeni) ovsem za nesrovnatelne kratsi dobu...
Puvodne zda se mely pamet z feritovych jader (jako Apollo), pak se provedl upgrade na polovodicovou pamet:
The upgraded GPCs have a semiconductor memory of 256,000 32-bit words; the older GPCs have a core memory of up to 104,000 32-bit words.
I ta nova pamet je snad odolna proti vypadku napajeni (neco jako EEPROM/flash RAM).
Pocitace samy jsou nejake derivaty IBMackeho mainframu S/360 ( novejsi v rade jsou S/390 a zSeries ), s pozmenenym mikrokodem.
