Solid State Drives for Your G4!

Cheryn tells me we are having trouble finding 80 or 120GB refurbished hard drives for our older Mac customers. There haven't been new ones available for years. We know you depend on us to help keep your old gear running efficiently. These brand new digital solid state drives have no moving parts making them not only faster but more reliable. We still think you should keep your system backed up but running from these super fast brand new drives only make sense. We haven't carried SSD drives much before but we think now that the prices are more affordable now is the time. We found the right kind of adapter that allows you to configure it for Master, Slave or Cable Select depending on your needs. That makes these more compatible and easily configurable with an included jumper. We can set these up for your system or you can use copy software to move your old data. Let us know how we can help speed up your G4 system. I tested these on our servers so you know they are fast and dependable.

2nd Quarter 2019 Edition
SUPER Kitchen Sink DVD

2019 Versions IN STOCK NOW! Install the latest updates. I added all the goodies you asked for. Now you can simply load them from the DVD or in some cases download them from the links. Categorized, Indexed and Described and most all include links to the download site and the authors web site so you can read more about them. ORDER NOW! Software section of the online store. If you haven't bought one in a while this is a good time to update. Have an iPod, iPad, or iPhone? We now have a directory that has all the utilities in one directory. We also created a Virus,Trojan, Worm directory to make it easier for you to feel safe and even added some Adware removal tools. High Sierra and Mojave compatible software now identified.

SPECIAL NOTE: DO OPEN THE INDEX FILES THAT APPEAR AT THE TOP OF EACH FOLDERS DIRECTORY. I have added a MORE THAN A FEW items that there is not room for some on the disk. In this case I linked the direct download link and noted in the description. THERE ARE SOME REAL GEMS listed in the directories for download. Take a look!

We separated the Apple Updates DVD disks to allow you to order only the updates you need. While the updates are free from Apple some are quite large and take a long time to download. Having them on disk saves you time especially if you have more than one Mac. There will likely still be some hardware specific updates you will need to download from Apple to complete your installation. New High Sierra Updates added!

APPLE UPDATES DVD's! These DVD's allow you to update to the latest version of the OSX version you have installed. We are now selling them separately. The only DVD's that got updated this quarter are the AppleUpdates 10.10, 10.11, 10.12,10.13 and 10.14 and some now require 2 disks.

If you want to buy a complete set call and speak to Cheryn and she will make you a group deal price. From now on though we will be offering each disk separately at a good price and of course our pricing always includes shipping.

WIRELESS N - Back In Stock! Lower Prices!

I thought it would be a long while before I upgraded my Wireless G components to N. Cost keeps me from running out and adopting new technology quickly and I am certain that many of you are like me when it comes to parting with cash. I have had my eyes out for a low cost alternative that would enable me to install the much faster and longer range N. Well I finally located some market USB Dongles that we could get drivers for. I replaced our trusty LinkSys Wireless G Router with a refurb N unit and have started using these new cards. You get more bars at even marginal locations with these cards and the transfer rates are astounding. I can now see how video can easily be shared. Perhaps shortly I will have a Mac permanently attached to the TV. Makes it better to watch those shows I missed from online and all without stringing CAT 5E across the floor. We provide the drivers on our new SuperSink CD (a $14.77 value) included with each PCI Wireless N Card or USB Dongle.

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 $14.99 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: Check often we get a few StyleWriter's in that work with your older Mac. Use USB Printers when you can but check to make sure they support your OS version and buy the cables from us. No USB? OS8.6-9.2 and a card will put you PCI bus PowerMac owners in business. USB Printers that work in 9 are harder to find. We try to stock a few USB refurbed units that work in 9. 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 Mac 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.

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 Apple Macintosh Computer 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.

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

Email your list: cheryn or use the email for quotes.

RECYCLING If you have Mac 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 email. 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 email for quotes.

SHIPPING INFO: All orders are packed same or next day. We strive to have all items shown in our store in stock. Should any item be out of stock we will contact you either via email or phone to let you determine what you want to do. Depending on your order we normally ship one of three ways. Small orders both in size and dollars are generally mailed. Items of size and or value are shipped either FedEx Ground or UPS Ground depending on the area you live in. When your order is entered you will receive an email receipt, after it is processed and shipped you will receive an additional email notice (assuming you gave us a valid email) with your tracking number on UPS or FedEx orders. All large orders have to be signed for. Shipping is always included in the bottom line price of your order. No additional charges are added (except for sales tax in Oklahoma). Call if you need express shipping.
