1. New Features 1.1 3.7-0 1.1.1 SCP - Added SET THROTTLE and SET NOTHROTTLE commands to regulate simulator execution rate and host resource utilization. - Added idle support (based on work by Mark Pizzolato). - Added -e to control error processing in nested DO commands (from Dave Bryan). 1.1.2 HP2100 - Added Double Integer instructions, 1000-F CPU, and Floating Point Processor (from Dave Bryan). - Added 2114 and 2115 CPUs, 12607B and 12578A DMA controllers, and 21xx binary loader protection (from Dave Bryan). 1.1.3 Interdata - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state. 1.1.4 PDP-11 - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state (WAIT instruction executed). - Added TA11/TU60 cassette support. 1.1.5 PDP-8 - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state (keyboard poll loop or jump-to-self). - Added TA8E/TU60 cassette support. 1.1.6 PDP-1 - Added support for 16-channel sequence break system. - Added support for PDP-1D extended features and timesharing clock. - Added support for Type 630 data communications subsystem. 1.1.6 PDP-4/7/9/15 - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state (keyboard poll loop or jump-to-self). 1.1.7 VAX, VAX780 - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state (more than 200 cycles at IPL's 0, 1, or 3 in kernel mode). 1.1.8 PDP-10 - Added SET IDLE and SET NOIDLE commands to idle the simulator in wait state (operating system dependent). - Added CD20 (CD11) support. 2. Bugs Fixed Please see the revision history on http://simh.trailing-edge.com or in the source module sim_rev.h.
