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.

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.

1st Quarter 2021 Edition
SUPER Kitchen Sink Thumb Drive

NOW A 16 GB USB Thumb Drive! 2021 Versions IN STOCK NOW! Install the latest updates. I added all the goodies you asked for. Now you can simply load them from the thumb drive 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. Mojave, Catalina, and Big Sur 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 drive. 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! With the added space I am now including more versions for more OS versions!

We separated the Apple Updates on Thumb Drives 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. Mac OS 11 Big Sur Compatibility Updates added!

APPLE UPDATES THUMB DRIVES! These 16 GB Thumb Drives (various colors) allow you to update to the latest version of the OSX version you have installed. We are now selling them separately. The 10.13 High Sierra required a larger 32 GB Thumb Drive for enough space.

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.

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 and you don't have to mess with rebates. These are new units and are bright and sharp. We don't carry much in CRT monitors but do check the monitor section. 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.

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.

  • We repair out of warranty laptops at fair prices, a laptop expert technician is on staff.
  • We also provide level one 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.
  • We can affordably fix iMacs (black screen of death) with OSX that have lost video! Call for pricing.

ABOUT REFURBISHED COMPUTERS: Operator Headgap Systems purchases good used Mac systems in quantity. Our professional staff of refurbishers clean, perform over 50 diagnostic tests including drive formatting. All our systems come smartly configured and ready to use. Our units 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 one of our refurbished Apple computer 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 gives you an additional browser choice over Apple's Safari and much, much more. Plus we always include the OSX Super Kitchen Sink DVD that is chock full of other programs you may find useful and wish to add for use with your new system.

TRADE-INS: Many times when you are ready to upgrade your old 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 for certain older systems. The following are on the list: iMac G4, QuickSilver G4, PowerMac 7300, PowerMac 8600, Quadra or Centris 650, and Mac IICI's & SI's. The units need to be cosmetically in good condition and working (at least chiming). Trade in value will vary from the top price for extra clean, that exceed stock configurations and down for less that prime units. Email: cheryn@biz.headgap.com for quotes. We are also purchasing good used working StyleWriters, and SCSI Zip Drives. WE BUY USED SONNET G4 AGP PROCESSORS.

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

RECYCLING If you have Mac items and Mac accessories 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@biz.headgap.com 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 formatted so have no fear about any data left on a hard drive. We properly recycle any items we end up having to discard.

UPGRADING THE OFFICE? We buy quantities of Mac systems & components. Email your list for a quote! Contact Us.

We don't carry the depth we use to in systems and it may require 7 to 10 days especially those that are custom builds. We appreciate your patience and business. 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.
