5531ccb175 ALL: Massive 'const' cleanup
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.

Most simulators can now also be compiled with a C++ compiler without
warnings.

Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.

253f8a8dcf VAX: Move CPU register and routine declarations into vax_defs.h
Avoid redundant declarations in every simulator module that uses them
and allow compiler to validate consistency of declarations and definitions.

8f54971706 rtVAX1000: Fix potential array overrun when enabling the QVSS graphics.
This can't currently happen since the rtVAX1000 doesn't include the
QVSS video device.  It probably should contain this device since VAXELN
was recently recovered and one of the features VAXELN provided was
a way for 'old' VAXStation hardware to be repurposed into X-Window
terminals.

c3a879da2d VAX: Change to load ROMs or other boot code directly from built in memory arrays.
Prior logic attempted to load the desired file from the current default directory and if that failed wrote the in memory boot code image to the desired file and then retried the desired load..

A user can still explicitly load a ROM image with a "LOAD -R romfile.bin" command prior to a BOOT attempt if they want to test or otherwise run with a different ROM.

6b4353f257 Returned the pdp11_cr device to the VAX Qbus systems and changed the pdp11_cr device to properly describe itself as a Qbus capable device when CR11 device is being simulated since it is a programmed I/O device and doesn't have bus addressing issues that DMA devices have. 2013-02-04 06:53:10 -08:00

8640cd6537 - Removed pdp11_cr and pdp11_ry from the Qbus VAX simulators since these devices can't address the full Q22 address range.
- Added validation checks in auto_config to reject enabled devices which aren't Q22 capable on Q22 platforms.
- Changed pdp11_cr device to be default disabled in the PDP11 simulator
