WHY DON'T WE STOCK MANY LATER MODEL MACS?

When Mojave 10.14 Mac OS came out I realized that things had changed. You see the iMacs that are capable of running Mojave 10.14 are not as serviceable as the earlier units. Many models have no Optical Drive, some have a fixed amount of RAM from the factory so no upgrading. They started attaching the screens with cement so changing out components or simply repairing them became difficult and expensive. The Laptops are close behind this as well with less servicable and upgradable capabilities. That being said you know we can get what you need. If you don't see what you want give us a call and we will gladly quote on a later system that will meet your needs. Unless you have a reason to run the very latest software there is no reason to buy an unservicable machine. A slighly older model with extra RAM and perhaps a Solid State Hybrid Drive will probably meet your needs and give you years of service life for a lot less money than new.

ABOUT MONITORS: We now stock a select few Flat Panel LCD's. These are tested on Macs and we will not sell any of the dark slow and fuzzy junk you sometimes find at bargain basement prices. These are new units (unless noted) and are bright and sharp. We don't carry much in CRT monitors. They are heavy to ship and the larger ones are subject to damage in shipping. We recommend you use our low cost Mac to PC monitor adapter (see our monitor section) ). Easily adapt most any PC monitor to your older beige Macintosh including flat panels LCD's. Compare at $24.99 to $44.99 our Special Price $19.99 includes domestic shipping. G3 Blue & White, G4 and above take PC HD15 connections straight up! No adapter needed for those models. We also carry video card upgrades for many models that really improve your systems performance. Our adapters even allow small LCD use with older Mac systems.

ABOUT PRINTERS: USB Printers that work in 9 are harder to find. Many of our customers are using PrintToPDF to output their 9 pages to a file and then move them to a more modern system to print. See the printer section of the store. See my tech tips printer section for more tips: http://resale.headgap.com/bobsmactips.html#print

ABOUT MODEMS: We have internal modems for many different models. We also have a few used serial modems. See the modem section of our online store. Zoom makes a 56K USB Modem Model 3095, that will work with your system. It works with older classic OSes from 9.2 (and probably 8.6 if you manually install the CCL) up to 10.6 although you will have to likely manually install some components.

MAC REPAIR & UPGRADES: Want to repair or update your old (out of warranty) Mac and don't know how? Send us your old system and let us install any of the items we sell. Add processor upgrades, optimize your existing processor, more ram, larger drives, or perhaps an internal burner. We also professionally install all Apple Macintosh OS versions including OSX and update it to the latest versions from Apple. We also test, and thoroughly clean inside and out. Give us a call or email us with your particulars.

• We repair out of warranty laptops at fair prices.
• We also provide low level hard drive recovery at reasonable rates. Call for details.
• Need your old data moved to a new drive or system? Let us do that for you.
• Need your old floppies, Zips, Syquests, etc. moved to CD or DVD - give us a call.

ABOUT 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 used Mac systems in quantity. Our professional staff of refurbishers clean, perform over 50 diagnostic tests including DOD level drive formatting. All our systems come smartly configured and ready to use. Our refurbished used Mac Computers come with the required cables and cords (except keyboards unless noted, use your old one or available extra). We even include a free mouse pad. We offer a quality refurbished product at the lowest possible price and stand behind our systems with a 90 day warranty. Why use reconditioned equipment? Read more.

NICELY CONFIGURED?: 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, much more. On older PPC equipped systems including G4 and 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 find useful and wish to add for use with your new system.

TRADE-INS OR SELL YOUR OLD MAC Remember we pay wholesale prices. Many times when you are ready to upgrade your old used Apple computer 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.

We are also purchasing good used Apple Desktop Bus Mouse II ADB Mice and ADB Keyboards.

Email your list: cheryn or use the online form for quotes.

RECYCLING If you have computing Macintosh items and hate to throw them away but figure they have little or no value in todays market, rather than dumping them to a landfill, write us with a list. Email: cheryn or the online form. Any of the items we can use we will pay your shipping. You can rest assured that we will put your old Mac items back into circulation either using them to repair old equipment or including the items with systems. All hard drives are thoroughly DOD level formatted so have no fear about any data left on a hard drive. We properly recycle any items we end up having to discard. We do not accept CRT type monitors or LaserWriters (too heavy and little value).

UPGRADING THE OFFICE? We buy quantities of Mac systems & components. Email: cheryn or use the online form for quotes.
