# This is the 1st commit message: Richard Lukes - 18 FEB 2024 This is my initial commit of my swtp6809 emulator which is a modified version of the swtp6800 emulator. The following changes are still outstanding: - various code clean up tasks and removal of temporary comments - bootrom.c - reset() appears to be performing attach() funtion, I plan to clean up soon - mp-b3.c - want to add #define for 4 bytes per slot versus 16 bytes per slot - dc-4.c - trying to understand the changes I made from the original dc-4.c in the swtp6800 emulator - I will do additional testing, however, for now this boots Flex 9.0 and appears to be working fine # This is the commit message open-simh#2: In preparation of presenting for contribution as a "pull request". General clean up of code. Removed unneeded test prints that were used for debugging. Removed swtp_sbuge_bin.h which implemented BOOTROM code internally. Users should use "ATTACH BOOTROM <sbuge.bin filename>". Added reset() routine to CPU. If last line in INI file is "RESET CPU" then simulator goes straight into BOOTROM from reset vector at $FFFE. Tested with several FLEX 9 DSK files. Known issues are: 1) Backspace (BS) does not seem to work when running Flex 9. 2) When simulator starts up the PC has a value of $FFFF (and not $FFFE). 3) No DMAF1/DMAF2 disk emulation which is required for support of UniFlex. 4) No documentation has been written yet. However, I am more than willing to put something together. Note this code was developed using Debian on Raspberry Pi 4. There may be Unix/DOS file conversion issues. # This is the commit message open-simh#3: swtp6809 simulator being contributed to open-simh project open-simh#357 (Pull Request) - updates to code while writing the simulator usage guide - added copyright notice to relevant source code modules - used unix2dos to format source files for DOS line terminator conventions - source code files from swtp6800 with some changes: swtp_defs.h, dc-4.c - source code files from swtp6800 that are unchanged: mp-s. # This is the commit message open-simh#4: CMake: Reduce excess quoting cmake/cmake-builder.ps1 added quotes to arguments that contained spaces, so that arguments printed correctly for progress output. This introduced excess quotes that caused CMake (and likely other MS apps) confusion or argument misinterpretation. Instead of CMake seeing a single "Visual Studio 17 2022", CMake was actually seeing "\"Visual Studio 17 2022\"". This patch only adds the additional quotes when reporting progress or emitting debug output. Otherwise, command line arguments are passed unmolested. # This is the commit message open-simh#5: The user doc file for the swtp6809 simulator SWTP 6809 Simulator Usage guide.
