I've finished, and am debugging, a VAX-11/780 simulator, with the goal of running VMS V1, early BSD releases, and other 'first VAX' code. There are a couple of critical missing pieces. In particular, I need 1) 780 PROM bootstrap contents. This was the 4KB of PROM located in the MS780 memory controllers. A binary dump would be sufficient, the simulator can dissassemble VAX code. 2) LSI11 console PROM contents. The LSI11 console ran out of a boot PROM. This is less critical but would help with understanding the fine details of the console-CPU interaction. Again, a binary dump suffices. 3) VMS V1 floppy kit. While early tape distributions have been found, the console floppies have not. The most critical ones are the tape restore program and the system bootstrap (VMB). Getting a 780 online required - booting the console from its PROM - loading the standalone tape restore program into the 780 from the console - running the standalone tape restore program to copy VMS from the distribution tape to a hard disk - loading VMB into the 780 from the console - using VMB to boot VMS Any help would be appreciated. The 780 simulator, in its current incomplete state, is included in the SIMH source distribution, http://simh.trailing-edge.com. -- Bob Supnik bob.supnik(a)sicortex.com VP Engineering Tel: 978.897.0214 x202 SiCortex Fax: 978.461.2444 One Clocktower Place Cell: 508.344.0398 Suite 100 Maynard, Ma 01754
