 Motorola 68040 - Wikipedia, the free encyclopedia
The Motorola 68040 is a microprocessor from Motorola, released in 1990.
It is the successor to the 68030 and is followed by the 68060 (the 68050 was an abandoned project and never shipped, the 050 was to the 040 what the 030 was to the 020, a simple die shrink and cache size increase).
Motorola's 68882 external FPU was known as a very high performance unit and Motorola did not wish to risk integrators using the "LC" version with a 68882 rather than the more profitable full "RC" unit.

The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors, which were all mostly software compatible.
Motorola ceased production of the 68000 in 2000, although derivatives, notably the CPU32 family, continue in production.
The Motorola 68901 had a number of severe defects, including the ability to lose the highest-priority interrupt if it and the clock interrupt happened within some window of each other.

Note that there is no 68050, this is because the design that was destined to be the 68050 was eventually released as a version of the 68040.
There is also no revision of the 68060, as Motorola was in the process of shifting away from the 68k and 88k processor lines into its new PowerPC business, so the 68070 was never developed.
Should Motorola have decided to stick with the 680x0 series it is very likely that the next processor (68080) would have resembled Intel's P6 architecture.

 Sun 3/80 68030 Architecture
The case is a SparcStation 1 (or 1+ or 2) type "pizzabox" chassis, but the machine is NOT a Sparcstation -- it's a Sun3 using a Motorola 68030, but it's also one of the few Sun3 series machine to use the 68030 at all (previous Sun3 machines used a 68020).
Note that the smaller, blocked-off opening next to the 13W3 connector is, I assume, for a different framebuffer for the 3/80, which would have had a 9pin connector for the older monochrome monitors which were used on the early Suns.
An important point to remember is that the 68030 CPU is instruction-set compatible with the 68020, so pre-compiled binaries for the Sun3 series 68020 machines will work with the Sun 3/80.

It utilized a Motorola MC68EC020 CISC CPU (lacking MMU for memory protection and virtual memory to reduce costs) running at 14 MHz.
Because the unit's memory was shared between the CPU and the sound and video chips, expanding memory beyond 2 MB greatly increased the A1200's speed.
Unlike the A500 and A600, which were only incremental upgrades over the original A1000 released in 1985, the A1200 was a significant upgrade, featuring more than four times the processing power and greatly enhanced graphics capabilities.
