===Peripherals===
In 1984, the company changed direction to make peripherals for [[Macintosh]] computers: the HyperDrive (the Mac's first internal hard drive), the WideWriter 360 large format [[inkjet printer]], and the Personal Laser Printer (the first [[QuickDraw]] [[laser printer]]). Prior to closing, the company focused exclusively on laser printers.<ref name="gccprinters">{{cite news

HyperDrive was unusual because the original Macintosh did not have any internal interfaces for hard disks.  It was attached directly to the [[CPU]], and ran about seven times faster than Apple's "Hard Disk 20", an external hard disk that attached to the floppy disk port.

The HyperDrive was considered an elite upgrade at the time, though it was hobbled by Apple's [[Macintosh File System]], which had been designed to manage 400K [[floppy disk]]s; as with other early Macintosh hard disks, the user had to segment the drive such that it appeared to be two or more partitions, called Drawers.

In June 1985 Apple announced that installing GCC peripherals would not violate its warranty prohibiting installing non-Apple components. GCC said that it had cultivated the relationship by providing products to Apple employees.{{r|watt19860127}} The second issue of ''[[MacTech]]'' magazine, in January 1985, included a letter that summed up the excitement:

{{quote|The BIG news is from a company called General Computer. They announced a Mac mod called HyperDrive, which is a [[RAM]] expansion to 512K, and the installation of a 10 meg hard disk with the controller INSIDE THE MACINTOSH. This allows direct booting from the hard disk, free [[modem]] port, no [[serial I/O]] to slow things down, and no external box to carry around. Price is $2,795 on a 128K machine or $2195 on a 512K machine. They do the installation or you can buy a kit from your dealer.}}

In 1986 GCC shipped the HyperDrive 2000, a 20MB internal hard disk that also includes a [[Motorola 68881]] [[floating-point unit]],<ref name="watt19860127">{{Cite magazine |last=Watt |first=Peggy |date=1986-01-27 |title=Mac Plus musters support |url=https://books.google.com/books?id=33QfOHT69aMC&pg=PA27#v=onepage&q&f=true |access-date=2025-05-29 |magazine=Computerworld |pages=27,29 |volume=XX |issue=4}}</ref> but the speed advantage of the HyperDrive had been negated on the new [[Macintosh Plus]] computers by Apple's inclusion of an external [[SCSI]] port.  General Computer responded with the "HyperDrive FX-20" external SCSI hard disk, but drowned in a sea of competitors that offered fast large hard disks.

General Computer changed its name to GCC Technologies and relocated to [[Burlington, Massachusetts]]. They continued to sell [[laser printer]]s until 2015, at which point the company was disestablished.<ref>{{cite web|url=https://opencorporates.com/companies/us_ma/133124241|title=GCC Technologies|work=OpenCorporates|accessdate=January 9, 2022}}</ref>
