upgrade your old used Mac system may not be worth much,
especially to a dealer who is used to buying in quantity
at wholesale prices and has the units shipped in bulk

a few dollars. Here lately we have been having more
trouble locating older systems people are still buying.
We will begin offering trade-ins or to buy outright
certain older systems. The following are on the list:
used PowerMac G5, G4, QuickSilver G4, G3 Desktops,
PowerMac 7300, Quadra or Centris 650, 800, 840, and Mac
