[Simh] RSTS/E V9.6 Date Patch (New Thread, RSTS PreBuilt Kits).

[Timothe Litt]

Even >I< didn't expect me to look, but I did (and surprisingly, I
remember PDP-11 opcodes):

044050  000176  000000  ? 20027         ; cmp r0,#124
044050  000200  000000  ? 126

Er, either the comment or the patch is wrong.  124 /= 126, even in octal :-)
