Macintosh SE
The SE was available in a few different hardware configurations including dual 800KB disk drives, single disk drive and a hard disk, high density disk drive.
Powered by an 8MHz Motorola 68000 processor. Typically shipped with 1MB RAM and is expandable to 4MB. Replaced by the Macintosh SE/30.
Overview
The Macintosh SE personal computer combines the compact design of the Macintosh Plus with added power, faster file access, and greater flexibility. It includes an internal expansion slot that allows you to customize the system to meet your needs, and it offers a choice of three storage configurations. The Macintosh SE uses the Apple FDHD Internal Drive, a high-capacity 3.5-inch floppy disk drive capable of reading 400K, 800K, and 1.4-megabyte Macintosh disks. In addition, the FDHD drive lets you read from and write to MS-DOS, OS/2, and ProDOS formatted disks.
This combination of capabilities makes the Macintosh SE an excellent choice for use in multivendor environments. Adding to the power and versatility of the Macintosh SE is Apple's multitasking operating system, MultiFinder. MultiFinder allows you to open multiple applications concurrently and perform background tasks-such as printing documents on laser printers-while you continue to work in an application.
In addition to the system software, the Macintosh SE is packaged with Apple's HyperCard software. HyperCard lets you organize information on your computer the way you organize it in your mind-by association and with unlimited cross-references. The Macintosh SE continues to off er the benefits that characterize all Macintosh computers: a consistent user interface and intuitive design that make the Macintosh easy to learn and use. The Macintosh SE is compatible with existing Macintosh hardware and software, and lets you share files with other members of the Macintosh family of computers.
General Information
CPU
MC68000; 32-bit internal architecture; 7.83-megahertz clock speed.
Memory
The Macintosh SE requires 150-ns (or faster) SIMMs. RAM speed is indicated by the -xx number after the manufacturer’s part number (-15 indicates a 150-ns SIMM).
Two logic boards are available for the Macintosh SE. The original board uses a solder-type resistor to identify system memory configurations; a resistor is installed in R35 for 1 MB and in R36 for 2 MB. The revised logic board uses a jumper to identify system memory. On boards with a jumper, remove it entirely for using 4MB RAM.
256 bytes of parameter memory.
Audio
Four-voice sound with 8-bit digital/analog conversion using 22-kilohertz sampling rate.
Expansion
Includes SE PDS expansion. Common types of upgrades include CPU accelerators, video cards for external monitors, Ethernet network adapters.
Notes
- The SE board doesn't use the same leaky capacitors as most other Macs in the 80s and 90s, but hobbyists should be aware that the battery may still leak due to age.
- SE/30 PDS cards cannot be used in the SE PDS slot.
- From MacsBug or the interrupt debugger, enter "G 41D89A". (To get into the interrupt debugger, press the button on the left side of your machine closer to the back. If you're running System 7, just Shut Down your machine, then while the "you may turn off your Macintosh safely" dialog is displayed, press the button.) This brings up a slideshow displaying four bitmap pictures of the Macintosh development team. Reboot (hit the button on the left side of the machine closer to the front, with the triangle on it) to get out of the endless cycle. Also, entering "G 4188A4" into the debugger gives you a tiny "Stolen from Apple Computer" message in the upper left-hand corner of your screen.
