The Macintosh XL is a modified version of the Apple Lisa personal computer made by Apple Computer, Inc. In the Macintosh XL configuration, the computer shipped with MacWorks XL, a Lisa program that allowed 64 K Macintosh ROM emulation. An identical machine was previously sold as the Lisa 2/10 with the Lisa OS only.
The Macintosh XL had a 400K 3.5" floppy drive and an internal 10 MB proprietary Widget hard drive with provision for an optional 5 or 10 MB external ProFile hard drive with the addition of a parallel interface card. The machine used a Motorola 68000 CPU, clocked at 5 MHz together with 512KB RAM. At the time of release in January 1985, the Macintosh XL was colloquially referred to as the "Hackintosh", although this name has since been used more generally to describe Macintosh computers assembled from unusual combinations of parts or, after Apple's transition to Intel processors, to denote PCs running OSx86, a hacked version of Mac OS X. The Macintosh XL was discontinued in April 1985.
Because of its roots as a Lisa — unlike all other Macintosh computers — the stock Macintosh XL used rectangular pixels. The resolution of the Macintosh XL's 12 inch (30.5 cm) display was 720x364. Square pixels were available via the Macintosh XL Screen Kit upgrade that changed the resolution to 608x432. The CPU could be replaced with a new CPU board containing up to 8 MB RAM, called the XLerator 18. The maximum upgraded RAM with conventional add-in RAM cards was up to 2 MB - four times larger than the maximum capacity of earlier Macintosh computers. (With modifications to the CPU board, the Macintosh XL could accommodate up to 4 MB of RAM.)
MacWorks Plus was developed by Sun Remarketing as a successor to MacWorks XL in order to provide application compatibility with the Macintosh Plus computer. MacWorks Plus added support for an 800 KB 3.5-inch floppy disk and System software up through version 6.0.3. MacWorks Plus II extended that to the same 7.5.5 limit imposed on all 68000 processors.
