The Macintosh 512K Personal Computer, the second of a long line of Apple Macintosh computers, was the first update to the original Macintosh 128K. It was virtually identical to the previous Mac, differing primarily in the amount of built-in memory (RAM), which quadrupled the original's. This large increase earned it the nickname Fat Mac.

Like the 128K Macintosh before it, the 512K contained an 8 MHz Motorola 68000 connected to a 512 KB DRAM by a 16-bit data bus. Though the memory had been quadrupled, it could not be upgraded. A 64 KB ROM chip boosts the effective memory to 576 KB, but this is offset by the display's 22 KB framebuffer, which is shared with the DMA video controller. It shared a revised logicboard with the re-badged Macintosh 128K (previously just called the Macintosh), which streamlined manufacturing.

Shipping will be quite expensive due to the weight of this item, but feel free to arrange for your own courier to collect from my office, in order to bypass the shipping charge.
