Wayne Warthen	ab7c566270	Abstraction of Font File Processing Moved common font data file processing (including decompression) into core code and removed redundant code from VDA drivers.	7 months ago
Wayne Warthen	bccd80882c	BPBIOS Sources From Jörg Linder Jörg Linder has disassembled and thoroughly commented a great deal of the BPBIOS binaries. This was an incredible amount of work. I have added all of these to the RomWBW build scripts and will ultimately integrate them more completely.	8 months ago

Wayne Warthen	26a87a16a8	KBD Driver Pre Init - Updated KBD driver to use PREINIT to disable interrupts.	1 year ago
Wayne Warthen	f9ed5651e6	KBD Interrupt Processing Cleanup - I finally realized there was a much simpler way to setup the instance data pointer (IY) for the interrupt handler. This implements the change and reduces the complexity of the code. - Related to PR #460	1 year ago

Dean Netherton	fa45185945	msx-keyboard: corrected implementation of msx-keyboard's integration to the timer tick handler	1 year ago
Wayne Warthen	1d8c0c9c46	eZ80 Follow-up - Added RCEZ80 platform option to Build.ps1 - Added EZ80 config settings to MASTER config (required to get build to work for some situations) - Modified a .EQU in cfg_RCEZ80.asm to a .SET. After adding config setting to MASTER config, the .EQU was causing a redefinition error. - I have temporarily removed some "TRANSLATE" lines in ez80uart.asm. They were attempting to place a value greater that 0xFFFF in a register and generated an assembly error. - Modified a few JR instructions in hbios.asm to JP due to out-of-range errors. - Modified std.asm to "nest" a conditional. The Windows assembler does not ignore the remainder of a complex conditional when it should. - Modified tms.asm to replace the PRTS macro with alternative lines. The Windows assembler cannot handle a string longer than about 8 characters in a macro argument. - Added the TIMER utility to the ROM disk. Not sure what happened there. It was included in the Windows build, but not the Linux build. There is room for it, so I added it to the Linux build to get a binary exact build compare.	1 year ago

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	67d23dc540	Tweaks to NABU Support - Include NABU in pre-built ROMs - AY sound driver works (but poorly)	2 years ago
Les Bird	438df9a80b	NABU Personal Computer integration - nabu.asm and nabukb.asm contain code to support the NABU hardware.	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	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	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
Wayne Warthen	792e76b069	Duodyne PS/2 Keyboard - Enable PS/2 keyboard input for Duodyne Media I/O board video terminal. - Minor cleanup in TUNE to properly handle Duodyne ACR values.	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	cdb9f9b40a	Initial Release Candidate for v3.4 - Minor doc updates - Comment updates in ansi.asm and tms.asm - Correction to build process for ROMless systems - Fix for ZRC (default configuration) to use all available RAM	2 years ago
Wayne Warthen	def84eded9	Integrate Jose Collado's Screen Color Enhancements Credit and thanks to Jose Collado - This change enhances both the TMS driver and ANSI emulation to handle setting of screen foreground/background.	2 years ago
Wayne Warthen	72cdbdd4ad	Documentation Updates Inspired by Martin R - Implemented a crude mechanism to output config settings during a build which can be imported into the User Guide appendix.	2 years ago
Wayne Warthen	55a41ec0a3	TMS Driver Enhancement by Jose Collado - The 40 column mode of the TMS driver now conforms to the memory map from the TMS9918 documentation and is also now consistent with the existing TMS9918 video programs from the RC2014 forum.	2 years ago
Wayne Warthen	7ac88efac1	Support for VGARC Initial support for Bill Shen's VGARC video/keyboard module for RCBus.	3 years ago
Wayne Warthen	4d9c93734f	Support Serial Keyboard with Video Displays Added configuration setting VDAEMU_SERKBD which can be used to specify any serial unit # to be used as the keyboard for the video terminal. Default value is $FF which means to use the default hardware keyboard. All other values mean that terminal input is to come from corresponding serial unit #. Also a couple more tweaks to the p-System boot volume.	3 years ago
Wayne Warthen	d2e1e5be4b	Enable WAIT Signal for 9958 Video Credit to Alan Cox. This seems to allow a 9958 video chip to run with a Z180 without added wait states.	3 years ago
Wayne Warthen	2b4631195a	Misc Updates Based on Input from Eluan Miranda I got a very nice email from Eluan Miranda. He pointed out a few inconsistencies in the video and audio driver configurations. I made a few adjustments to clean things up.	3 years ago

Wayne Warthen	982906757e	Support QP/M TIMDAT Routine QP/M is a CP/M 2.2 replacement for BDOS/CCP. However, it adds it's own concept of date/time stamping. Support for the QP/M date/time routine has been added. You can configure QP/M to find the vector at address 0x0010. A sidenote on QP/M. By default, it uses 2 bytes at address 0x0008 to store the current drive/user. This will conflict with RomWBW's use of RST 08 for API function calls. I recommend using address 0x000E when configuring QP/M for the location of the current drive/user.	4 years ago
