Only a few million users had obtained consoles by the end of 2000 due to manufacturing delays.
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
However the New Slim Silver Models have more issues with playing PlayStation games than the first PS2 revisions.
After an apparent manufacturing issue caused some initial slowdown in producing the new unit, Sony reportedly underestimated demand, caused in part by shortages between the time the old units were cleared out and the new units were ready.
Sony also advertised heavily as well and it had the advantage of being supported by Electronic Arts.
V7 and V8 are also similar, and V9 (model number SCPH-50000/SCPH-50001) added the Infrared port for the optional DVD Remote Control, removed the widely unused FireWire port, added the capability to read DVD-RW discs, and a quieter fan.
V0 did not have a built-in DVD player and instead relied on an encrypted player that was copied to a memory card from an included CD-ROM (normally, the PS2 will only execute encrypted software from its memory card, but see PS2 Independence Exploit).
Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port.
Many analysts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PS2 launch seemed unimpressive and gaffe-prone, compared to the well-planned launch of the Sega Dreamcast, which was making a genuine attempt to woo developers and which had better launch titles.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
With a price of $299.99 per console, Sony made gross sales of roughly $153,000,000.
