Motorola 68050



There was no 68050. The successor to the Motorola 68040 was the Motorola 68060.
The even numbers (68000, 68020, 68060) were reserved for major revisions to the 680×0 core. The odd numbers (68010, 68030, 68050) were minor upgrades from the previous chip. For example, the Motorola 68010 was a Motorola 68000 with some minor enhancements and modifications to some user/superuser instruction assignments. The Motorola 68030 was a Motorola 68020 with an MMU and more minor enhancements. The 68050 would have been a 68040 with some bugs fixed, which didn’t really warrant a new name so it was sold as a 68040.
