Mac Plus motherboard, 800KB floppy drive.serial ports: DB-9 modem and printer ports.keyboard attached via coiled telephone-like cable.RAM: 128 KB, expandable to 512 KB with 150ns RAM chips (not Apple supported), to 4 MB with third-party upgrades.Requires Mac OS 0.97 through 3.3 (System 3.2 and Finder 5.3).(Please, don’t even think of converting a working one – you can always find someone interested on Classic Macs Digest or the Vintage Macs email list.) Details You can convert a non-working compact Mac into a Macquarium. (It’s commonly told that the original Macintosh would have had 256 KB of memory if RAM prices hadn’t been so high.) The Macintosh was supplemented by the 512K in October. In fact, Apple’s argument for a closed box (no slots) was that the high speed serial port was fast enough for anything you might want to add to the Macintosh – this was certainly not true for hard drives. If you didn’t crave a lot of speed, you could even add a serial hard drive. Apple sold 70,000 during its first 100 days on the market. What didn’t it have? A SCSI port, 5.25″ floppies, backward compatibility with the Apple II, III, or Lisa.īut it had twice as much memory as the popular Commodore 64, put 2.5 times as much data on a floppy disk as the IBM PC’s single-sided 5.25″ disk, included two serial ports (one which could be used for networking at the then-incredible speed of 230.4 kbps), and a totally graphical operating system, all packed into the cutest, friendliest package the computer industry had yet seen.

Early 128Ks simply said Macintosh on the back, while later ones were marked Macintosh 128K to distinguish them from the later Macintosh 512K.Įquipped with 128 KB RAM, 64 KB ROM, a 3.5″ 400 KB floppy drive, a 1-bit 512 x 342 pixel b&w monitor, a mouse, and a couple applications (MacWrite and MacPaint), the Macintosh was destined to change the face of computing forever – it not only created the Mac look and feel, it also inspired forthcoming versions of Microsoft Windows and several other windowing interfaces. Introduced in January 1984 (along with a revised Lisa), this Macintosh didn’t have a model number – it was simply the Macintosh.
