Notes For V3.8
The makefile now works for Linux and most Unix's. However, for Solaris and MacOS, you must first export the OSTYPE environment variable: > export OSTYPE > make Otherwise, you will get build errors. 1. New Features 1.1 3.8-0 1.1.1 SCP and Libraries - BREAK, NOBREAK, and SHOW BREAK with no argument will set, clear, and show (respectively) a breakpoint at the current PC. 1.1.2 GRI - Added support for the GRI-99 processor. 1.1.3 HP2100 - Added support for the BACI terminal interface. - Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions. 1.1.4 Nova - Added support for 64KW memory (implemented in third-party CPU's). 1.1.5 PDP-11 - Added support for DC11, RC11, KE11A, KG11A. - Added modem control support for DL11. - Added ASCII character support for all 8b devices. 1.2 3.8-1 1.2.1 SCP and libraries - Added capability to set line connection order for terminal multiplexers. 1.2.2 HP2100 - Added support for 12620A/12936A privileged interrupt fence. - Added support for 12792C eight-channel asynchronous multiplexer. 1.3 3.8-2 1.3.1 SCP and libraries - Added line history capability for *nix hosts. - Added "SHOW SHOW" and "SHOW <dev> SHOW" commands. 1.3.2 1401 - Added "no rewind" option to magtape boot. 1.3.3 PDP-11 - Added RD32 support to RQ - Added debug support to RL 1.3.4 PDP-8 - Added FPP support (many thanks to Rick Murphy for debugging the code) 1.3.5 VAX-11/780 - Added AUTORESTART switch support, and VMS REBOOT command support 2.
