This made the machine run more slowly than several of its competitors, despite the nominally high clock rate.
MACINTOSH HOME DESIGN SOFTWARE CODE
Such an arrangement reduced the overall performance of the CPU as much as 35% for most code as the display logic often blocked the CPU's access to RAM. The 68000 and video controller took turns accessing DRAM every four CPU cycles during display of the frame buffer, while the 68000 had unrestricted access to DRAM during vertical and horizontal blanking intervals. The RAM in the Macintosh consisted of sixteen 4164 64kÃ≱ DRAMs. Unlike the Apple II, no source code listings of the Macintosh system ROMs were offered. The boot procedure and some operating system routines were contained in an additional 64 KB ROM chip. The centerpiece of the machine was a Motorola 68000 microprocessor running at 7.8336 MHz, connected to 128Â KB RAM shared by the processor and the display controller. Not many computers are this legendary or can make the claim that even being from 1984 its direct descendants are still sold today. LGR - Macintosh 128k Vintage Computer Review - The first Macintosh. Upon the release of its successor, the Macintosh 512K, it was rebranded as the Macintosh 128K. Sales of the Macintosh were strong from its initial release on January 24, 1984, and reached 70,000 units on May 3, 1984. The Macintosh was introduced by the now-famous $370,000 (equivalent to $871,550 in 2017) television commercial by Ridley Scott, "1984", that most notably aired on CBS during the third quarter of Super Bowl XVIII on January 22, 1984. It had an initial selling price of $2,495 (equivalent to $5,877 in 2017). A handle built into the top of the case made it easier for the computer to be lifted and carried.
Its beige case consisted of a 9Â in (23Â cm) CRT monitor and came w ith a keyboard and mouse.
The Macintosh 128K, originally released as the Apple Macintosh, is the original Apple Macintosh personal computer.
