3DHardware.net heeft een editorial geschreven over de nieuwe PC99 specificaties, die o.a. de dood van de fossiele ISA bus moet betekenen:
A second specification that will be quickly noticed on a PC 99 system is the color coding that all the PC 99 motherboards must have. If you've ever owned or meddled with a Packard Bell system you'll feel at home, and I'm sure this will make life a little easier, or at least give some comfort to hardware newbies taking their first, daring steps into the internal world of their PC's. But ISA isn't the only aged technology slated to be replaced by newer ones with the PC 99 specification. Although not required, Wintel strongly advice the replacement of old COM and LPT ports favoring USB and IEEE 1394 (AKA. FireWire). Printers are the only devices officially allowed to use the old ports although system builders are advised to use the newer ports for connection of printers.
