The System 100 was the first authorized Macintosh clone. It was built around a slightly modified Power Mac 8100 motherboard: Radius used a standard Mac DA-15 video port instead of the 8100’s 45-pin AV port.
The Radius Mac clones were probably the most heavy of the bunch, clad in thick metal to provide more RFI shielding than Apple’s Macs.
