Message-ID: <300003@hpclkms.HP.COM> Date: 23 Feb 90 21:57:39 GMT Organization: Hewlett-Packard Calif. Language Lab Lines: 12 I just got the 68040 User's Manual, and was perusing the appendix which discusses the various features of the different members of the 68000 family. In the table on page A-3, the CALLM instruction is shown to be implemented only on the 68020. However, on page 1-1, the 68040 is claimed to be user object code compatible with previous members of the 68000 family. What gives? Does the phrase "user object code compatible" mean "mostly user object code compatible"? Ken Sumrall ken%hpda@hplabs.hp.com ...!hplabs!hpda!ken
