RESTRICTION: The PDP-15 FPP is only partially debugged. Do NOT enable this feature for normal operations. WARNING: The core simulator files (scp.c, sim_*.c) have been reorganized. Unzip V3.2-0 to an empty directory before attempting to compile the source. IMPORTANT: If you are compiling for UNIX, please read the notes for Ethernet very carefully. You may need to download a new version of the pcap library, or make changes to the makefile, to get Ethernet support to work. 1. New Features in 3.2-0 1.1 SCP and libraries - Added SHOW <device> RADIX command. - Added SHOW <device> MODIFIERS command. - Added SHOW <device> NAMES command. - Added SET/SHOW <device> DEBUG command. - Added sim_vm_parse_addr and sim_vm_fprint_addr optional interfaces. - Added REG_VMAD flag. - Split SCP into separate libraries for easier modification. - Added more room to the device and unit flag fields. - Changed terminal multiplexor library to support unlimited. number of async lines. 1.2 All DECtapes - Added STOP_EOR flag to enable end-of-reel error stop - Added device debug support. 1.3 Nova and Eclipse - Added QTY and ALM multiplexors (Bruce Ray). 1.4 LGP-30 - Added LGP-30/LGP-21 simulator. 1.5 PDP-11 - Added format, address increment inhibit, transfer overrun detection to RK. - Added device debug support to HK, RP, TM, TQ, TS. - Added DEUNA/DELUA (XU) support (Dave Hittner). - Add DZ per-line logging. 1.6 18b PDP's - Added support for 1-4 (PDP-9)/1-16 (PDP-15) additional terminals. 1.7 PDP-10 - Added DEUNA/DELUA (XU) support (Dave Hittner). 1.8 VAX - Added extended memory to 512MB (Mark Pizzolato). - Added RXV21 support. 2. Bugs Fixed in 3.2-0 2.1 SCP - Fixed double logging of SHOW BREAK (found by Mark Pizzolato). - Fixed implementation of REG_VMIO. 2.2 Nova and Eclipse - Fixed device enable/disable support (found by Bruce Ray). 2.3 PDP-1 - Fixed bug in LOAD (found by Mark Crispin). 2.4 PDP-10 - Fixed bug in floating point unpack. - Fixed bug in FIXR (found by Phil Stone, fixed by Chris Smith). 2.6 PDP-11 - Fixed bug in RQ interrupt control (found by Tom Evans). 2.6 PDP-18B - Fixed bug in PDP-15 XVM g_mode implementation. - Fixed bug in PDP-15 indexed address calculation. - Fixed bug in PDP-15 autoindexed address calculation. - Fixed bugs in FPP-15 instruction decode. - Fixed clock response to CAF. - Fixed bug in hardware read-in mode bootstrap. - Fixed PDP-15 XVM instruction decoding errors. 2.7 VAX - Fixed PC read fault in EXTxV. - Fixed PC write fault in INSV.
