The Motorola 68030 ("sixty-eight-oh-thirty") is a 32-bit microprocessor in the Motorola 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced oh-three-oh or oh-thirty).
Motorola mainly used even numbers for major revisions to the CPU core such as 68000, 68020, 68040 and 68060. The 68010 was a revised version of the 68000 with minor modifications to the core, and likewise the 68030 was a revised 68020 with some more powerful features, none of them significant enough to classify as a major upgrade to the core.
A Motorola 68030 processor. The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory. Another improvement over the 68020 was the addition of a data cache.
The 68030 was released in speed ratings up to 50 MHz. The jump from the 68000/68010 to the 68020/68030, however, represents a major overhaul, with innumerable individual changes. By the time the 68060 was in production, Motorola had abandoned development of the 68000 family in favor of the PowerPC. The 68060 is the last 68000 family processor ...
The Motorola 68040 ("sixty-eight-oh-forty") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. [2] It is the successor to the 68030 and is followed by the 68060, skipping the 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced oh-four-oh or oh-forty).
In keeping with naming practices common to Motorola designs, the 68020 is usually referred to as the "020", pronounced "oh-two-oh" or "oh-twenty". The 020 was in the market for a relatively short time. The Motorola 68030 was announced in September 1986 and began deliveries in the summer of 1987. Priced about the same as the 020 of the time, the ...
The initial model has a 10 MHz Motorola 68000 CPU, 1 MB of RAM, and lacks a hard drive. The final model was released in 1993 with a 25 MHz Motorola 68030 CPU, 4 MB of RAM, and optional 80 MB SCSI hard drive.
The DayStar PowerCache was a Motorola 68030 processor card running at either 40 or 50 MHz, with an optional 68882 math co-processor.The PowerCache plugged directly into the Processor Direct Slot of the Mac IIci, while in the case of the Mac II, IIx or IIcx, a PDS slot was provided via an adapter that plugged into the CPU socket.
