The save/restore format has been updated to improve its reliability. As a result, save files prior to release 3.0 are no longer supported. The text documentation files are obsolete and are no longer included with the distribution. Up-to-date PDF documentation files are available on the SimH web site. 1. New Features 1.1 3.6-0 1.1.1 Most magnetic tapes - Added support for limiting tape capacity to a particular size in MB 1.1.2 IBM 7090/7094 - First release 1.1.3 VAX-11/780 - Added FLOAD command, loads system file from console floppy disk 1.1.4 VAX, VAX-11/780, and PDP-11 - Added card reader support (from John Dundas) 1.1.5 PDP-11 - Added instruction history 2. Bugs Fixed Please see the revision history on http://simh.trailing-edge.com or in the source module sim_rev.h.
