The power cable is a standard 3-prong PC power cable.
MAC QUADRA 605 EMULATOR SERIAL
On the back of the machine there are, from left to right, two ADB ports, an DB-19 external floppy port, a DB-25 SCSI port, two mini-DIN 8 serial ports and a mono headphone jack. The motherboard has a port called the Processor Direct Slot (PDS) which is used for CPU accelerators, two ports for the floppy drives and a 16-bit 50-pin SCSI port. The first SE's came with two floppy drives or one floppy and one hard drive (FDHD). Internally, there are two bays which can hold a floppy drive or a hard drive. The SE has a better SCSI bus than its predecessor, is slightly faster than any previous Mac and introduced a pretty quiet cooling fan. I also wonder if the 9-pin mice the oldest Macs use also command a price premium. Prior Macs used a RJ-11 interface and the keyboards for those machines are rather pricey these days. The SE is the first Macintosh to use the Apple Desktop Bus for its keyboards and mice. The graphics are monochrome at 512x342 pixels and the sound is output through an 8-bit 4-voice 22KHz DAC. It comes with 1MiB of RAM, using 30-pin SIMMs and has a Motorola 68000 running at 7.8336MHz. It comes with 800KiB floppy drives and can use standard 16-bit SCSI hard drives. However, it is by far one of the easiest Macintoshes to use from a price and usability perspective. The Macintosh SE is the fourth model in the Macintosh line, following the Macintosh 128K, 512K, Plus and 512Ke (Enhanced). In that process I will be sharing some of the issues I have encountered and solutions.
I recently acquired an earlier example of the line, a Macintosh SE, and decided it was worth getting it up and running.
It eventually evolved into a fully general purpose computer, but the systems were sufficiently popular even in the earliest days to enjoy a wide variety of software, including games. The original Macintosh was designed to be a low-cost productivity computer. Of course, to owners of any Macintosh computer, the GUI was something they had experienced since day one. The Graphical User Interface is something computer users have taken for granted for twenty-five years since Windows 95 computers became ubiquitous.
