The makefile now works for Linux and most Unix's. Howevr, 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. 1.2 GRI - Added support for the GRI-99 processor. 1.3 HP2100 - Added support for the BACI terminal interface. - Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions. 1.4 Nova - Added support for 64KW memory (implemented in third-party CPU's). 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. 2. Bugs Fixed Please see the revision history on http://simh.trailing-edge.com or in the source module sim_rev.h.
