| Release Price | $1499.00 |
| The Macintosh Classic can
best be described as a Macintosh SE without the expansion slot, but at
half the price. It replaced both the Mac Plus and the Mac SE in the
product line. There were two versions of the Classic, a $999.00 version that had only a single floppy drive and 1MB of built in RAM, and a $1499.00 version that included a 40MB hard drive and 2MB of RAM standard and are both capable of being expanded to 4MB internally. The cheaper Mac was intended to go head to head with the just released IBM PS/1. The Mac Classic came with a 1.4MB Super Drive that was able to read and write MS-DOS, OS/2, and Apple II ProDOS disks. The Classic has six ports along the bottom of its case in the rear. From left to right they are a 4 pin mini-DIN plug for connecting up to 3 input devices (such as the keyboard, mouse, and light pen), a19 pin female D-plug for connecting an external floppy drive, a 25 pin female D-plug for connecting up to 7 SCSI devices ( such as hard drives, CD ROMS, or scanners), an 8 pin mini-DIN plug for connecting a printer, another 8 pin mini-DIN plug for connecting a MODEM, and finally a mini stereo jack for earphones. As with all the earlier models of the Macintosh, the Classic comes with a built in 9 inch monochrome monitor capable of producing a very sharp image of 512 pixels by 342 pixels. This Mac Classic was added to the museum on August 15, 1999. It was purchased at a local flea market along with an Image Writer II printer and complete documentation. This was my first Mac and I was so impressed with it that I decided to add the Macintosh line to my museum even though they are not really 8-bit machines. |
