MEM(IV) 8/24/73 MEM(IV) NAME mem - core memory DESCRIPTION Mem is a special file that is an image of the core memory of the computer. It may be used, for example, to examine, and even to patch the system using the debugger. A memory address is an 18-bit quantity which is used directly as a UNIBUS address. References to non-existent locations cause errors to be returned. Examining and patching device registers is likely to lead to unexpected results when read-only or write-only bits are present. FILES /dev/mem BUGS There should be another mem file that looks at core using the system's address map.
