68010 class ICs
68010 information
Successor to the Motorola 68000 and followed by the 68020. Some instructions which were previously user mode were made system mode, which necessitated patches to a few programs.

The 68010's main advantage over the 68000 was that it could recover from a bus fault. The 68000 microcode didn't save enough state to restart all instructions; the 68010 corrected this fault. This allowed it to use paged virtual memory.

The 68010's DBxx (decrement and branch) instructions could hold and execute the preceding instruction in the prefetch buffer, allowing some two-instruction loops to execute without refetching instructions.

There is a 68010 variant that is pin compatible with the 68000. Some Amiga users replaced their 68000s with 68010s in order to get a small performance increase.

For more information on Motorola 680x0 processors please refer to the M68K FAQ here (text-version) or here (html version) and the USENET group comp.sys.m68k.

Also used in the HP9000 300/310 series of machines with an custom external HP MMU and also in the AT&T Unix PC which again contained a custom external MMU of DEC flavour.
