Redesigned to reduce expense and offer a modernized version of the highly popular Macintosh Plus, the Apple Macintosh Classic replaced the Macintosh SE (FD/HD). The Macintosh SE/30 had been released a year earlier as part of Apple’s flagship range. The Classic consisted of a 9 inch monochrome (Black and White Screen) set into a Compact case design. The motherboard was set into the base of the unit and floppy drive seperated the screen from the computer. Whilst it was slow for its day, the Macintosh Classic made up for it’s lack of speed by being offered for under $1000. By comparison, the SE/30, upon introduction was over six times that price at $6500.
The Macintosh Classic featured an 8 MHz 32 bit 68000 processor which unfortunately ran on a 16 bit data bus.
The Computer shipped with either 1 MB or 2 MB of RAM. It incorporated a Classic-specific “Memory Expansion Card” consisting of a 1 MB daughter card with two open slots, into which 30 pin 120ns SIMMs could be installed in equal pairs. A total of 4MB ram could be addressed.
The Macintosh Classic shipped with either a 1.44 MB disk drive or a 1.44 MB disk drive and a 40 MB SCSI hard drive (Model M0435LL/A). Although the hard drive could be technically upgraded, it required dis-assembly of the case and exposure of the high voltage circuitry that drove the internal CRT tube.
Video & Graphics:
The Mac Classic incorporated a 9″ monochrome (1 Bit) display. Driven by on-board VRAM, the display offered a resolution of 512×342. The video could not be upgraded.
The system was supplied with Macintosh System 6.0.7 and could be user-upgraded to 7.5.5.
The Mac Classic included somewhat different ports to the Mac 512k and Macintosh 128k. Consisting of ADB (Apple Desktop Bus), Floppy Drive port, SCSI Port (DB 25), Printer (8 pin mini din) and Modem port (again 8 pin mini din). A sound port was also included consisting of a 3.5mm mono jack port.
Built in Controls:
The Mac classic did away with the brightness knob for the screen and instead integrated it into the system software via the brightness control panel. The Classic is the only mac to have the ability to boot from ROM Disk by holding down command-option-x-o at startup.
The ROM Disk, named “Boot Disk” is 357 KB in size and contains Finder 6.1.x and System 6.0.3, a combination specifically designed for the Mac Classic. The ROM’s OS includes General, Brightness, Startup Disk, MacsBug and AppleShare Prep. However, these last two system programs load into 294 KB of the Classic’s RAM. Because this is in ROM, there is no way to add anything to the ROM Disk.
Apple offered 2 different variations, each with unique order numbers:
- M0421LL/A, configured with 1 MB of RAM and a 1.44 MB floppy disk.
- M0435LL/A, configured with 2 MB of RAM and a 40 MB hard drive was assigned order number .
