Eventually Apple released SEs with the SuperDrive which can handle high density disks. The floppy drives in the SE and its predecessors will work much more reliably with double density disks than high density disks. For floppy images, the Floppy Emu supports 400KiB and 800KiB images in the. This firmware cannot coexist with firmware which supports Apple II disk drives, but firmware updates can freely be done to revert to Apple II functionality. Floppy Emu has firmware that will allow it to function with a Macintosh via the external floppy drive port. This is where I once again sing the virtues of Floppy Emu. Macintoshes of the monochrome variety can always boot off floppy disks and fortunately Macintoshes do not care whether the floppy is internal or external. The large Power On button about the number row keys or to the very right of the Function Key row does not function on the SE. My keyboard came with the Alps SKCM Orange keys and they are a positive joy to type on compared to some keyboards I have come across of similar vintage. While you can do a fair bit of light computing with only a mouse, the system is useless without one. You can also daisy-chain a mouse to the keyboard instead of plugging it into the SE directly. Also, the keyboard has a detachable cable and a port on each side, so you can have the keyboard cable come out on the right or the left of the keyboard. The ADB ports on the back do not care which device plugs into which port. The Apple Desktop Bus Mouse which came with the SE has a model number G5431 and the Apple Standard Keyboard is M0116. If yours did not come with one, you can print a 3-D replacement. On the right side of the machine may be a piece of plastic called the programmer's switch which lets you soft reset the machine or generate an interrupt. Underneath the Apple logo on the front of the system is the screen brightness control. The power cable is a standard 3-prong PC power cable. 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.
