HEADGAP REFURBISHED COMPUTERS:
What makes us different is we not only clean and
thoroughly test each system, we many times replace the
hard drives, optical drives, memory with upgraded
replacements. Operator Headgap Systems purchases good

When you select any of our systems you get not only the
basic system software preinstalled. We update the OS
software to the latest version. We also install many open
source, freeware and shareware programs and configure
them for use on your system. For example LibreOffice is
an Open Source Clone of Office for the Mac. It allows you
to open and save Word, PowerPoint, Excel file in their
formats making it easy to exchange your work with other
Office users. We also install Flip4Mac and Perian which
extends Quicktime allowing you to playback many types of
multimedia files like .divx and .wmv in a larger variety
of formats. Firefox and TenFour Fox gives you an
additional browser choice over Apple's Safari and much,

G5 models we install an update Flash Plugin allowing
better YouTube playback. Plus we always include the OSX
Kitchen Sink that is chock full of other programs you may

OR SELL YOUR OLD MAC Remember
we pay wholesale prices. Many times when you are ready to
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
truck freight. Boxing and shipping your old system costs
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 G4, QuickSilver G4, G3 Desktops, PowerMac
7300, Quadra or Centris 650, 800, 840, and Mac IICI's and
SI's. The units need to be cosmetically in good condition
and working (at least chiming). Trade in value will vary
from the top wholesale price for extra clean, that exceed
stock configurations and down for less that prime units.
We are also purchasing good used Apple Desktop Bus Mouse
II ADB Mice, working StyleWriters, and SCSI & USB Zip
Drives. WE BUY USED SONNET G4 AGP PROCESSORS.
