Wayne Warthen	e41cd6d8d2	Support 40 and 80 Column Video for NABU - 40 column mode will work with original TMS9918 video chip - 80 column mode requires FPGA TMS video chip replacement	2 years ago

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

b1ackmai1er	842a79ae5d	Correct the logical sequence of the Duo Dual UART ports Make the first UART port detected be Channel A $78-$7F : CHSEL=1. ( logic 0 on the CHSEL selects the UART channel B while a logic 1 selects UART channel A. )	2 years ago

Wayne Warthen	074f2cfdb2	Fix for ROMless Restart Registration of terminal emulation was failing under ROMless operation after a (R)estart was performed at the Boot Loader. See <https://groups.google.com/g/retro-comp/c/bILDMVI97vo/m/Oj8sXdr7DAAJ>.	2 years ago

Wayne Warthen	9ad7798713	Update romldr.asm Correct conditional compilation for UNA.	2 years ago
Wayne Warthen	807999928e	Tweak Console Takeover Mechanism Based on input from Martin R, the console takeover mechanism has been modified to require that the space bar be pressed twice in a row on the character unit desiring to be the console. This reduces the chance of a spurious console takeover due to garbage input on serial ports.	2 years ago
Wayne Warthen	d93e639e4b	Added Console Takeover Mechanism - If enabled by AUTOCON config setting, you can press <space> at any character device to take over the console at the boot loader prompt. - Correction to SIOSEEK documentation in System Guide. Thanks and credit to Martin R.	2 years ago

Wayne Warthen	c7bee46f60	Workaround CH376 Reset Behavior I am encountering some CH376 chips that go haywire after a reset command. They stop responding for a very long time. I am seeing this only on "LC Tech" adapters and only on Z80 systems (not Z180). No idea what is going on, so I am giving up for now and removing the reset.	2 years ago
Wayne Warthen	e9b9782ede	Correction for CH Driver Config - Last check-in had a couple of config file errors which are corrected here. - Also updated Appendix A of the User Guide to reflect new CH37x port addressing.	2 years ago
Wayne Warthen	af00df9182	Update CH Driver Port Config for RCBus Systems - Updated to standardize on 0x3E/0x3F for primary CH device and 0x3C/0x3D for secondary CH device. Both devices are optional and detected automatically.	2 years ago
