About the only genuine Apple part of this early Mac hack is the motherboard, which was a defective 128K board. It had a bad SCC chip, which was socketed and replaced. The RAM was removed and replaced with 256K chips, and a Beck-Tech upgrade brought it to 1 megabyte. A Micah SCSI interface allowed attaching a prototype hard drive from Conner. The Micah interface would normally attach via a Killy clip to the CPU, but in this case wires were tacked directly to the chip’s pins. The floppy drive is an aftermarket model. Power comes from a small switching supply, and video is via an external IBM-style monochrome display via a 9-pin connector.
