Wayne Warthen	8c4a3d2b3d	Final Video Hardware Reset Changes - Modified TMS driver to always imbed an uncompressed font. This is because I have found no reasonable way to decompress a font while an OS is still active without mangling some of the OSes RAM.	2 years ago
Wayne Warthen	585c892a54	Add Genesis Platform ID (STDZ180)	2 years ago
Wayne Warthen	49025dca44	Cleanup - Documentation update - Fixed minor screen anomaly related to new video reset handling	2 years ago
Wayne Warthen	2d8c37307d	Improve Video Hardware Reset - This change avoids clearing the screen every time an OS reset occurs. A non-destructive VDC reset is now performed that leaves the screen contents and cursor position unchanged. - If an application overwrites the video RAM, then the screen may contain garbage upon return to OS. However, the console will still be functional and the user can just press enter a few times to clear the screen.	2 years ago
Wayne Warthen	d294fb6d09	Reset Video Hardware on OS Reset - When an OS performs a reset operation, the HBIOS hook has been extended to automatically reset the video hardware of the CRT device (if it exists). - This should go a long way toward fixing corrupt video after an application is run that reprograms the video hardware. - An OS reset may or may not be performed when an application exits depending on the behavior of the application. So, if an application exits without initiating a reset, then the video will not be reset. Most applications that muck with the video chip directly will perform the reset at exit, so this is not normally an issue. - If the OS encounters an error (such as drive not ready when doing a DIR), the error message may be erased by this new behavior depending on the specific scenario.	2 years ago
Wayne Warthen	1649b6093b	Improve TMS Reset	2 years ago
Wayne Warthen	d50593a70e	Improve TMS Reset & SN76489 Early Init - The TMS reset function was missing a call to re-initialize the CRT registers. This has been added. - The SN76489 powers up in a dreadful state where it is emitting loud noise until initialized. Added a PREINIT entry point to initialize the registers earlier. Still not great, but a lot better.	2 years ago
