Wayne Warthen	5d81574226	Preliminary Support for ROMless Booting	4 years ago
Wayne Warthen	9f3c9e180d	Add PIO Driver - Just a stub that detects and initializes the hardware.	4 years ago
Wayne Warthen	51d9bdb655	Minor ASSIGN Fixes, Add 2PIOTST - Improved ASSIGN operation under CP/M 3 to better handle BIOS function invocations - Added 2PIOTST for testing the DUALPIO MBC board - Increased default RAM drive size for ZRC	4 years ago
Wayne Warthen	36b160f934	Minor Cosmetic Cleanup Primarily fixed the Z280 config files to display the correct CPU speed in boot messages.	4 years ago
Wayne Warthen	bf965c2604	Minor Z280 Fixes - Fixed the ROM VERIFY functionality on Z280. It was indicating errors incorrectly. - Revised the way that ZZRCC is built to remove a bunch of complexity that was causing issues. An implication of this is that ZZRCC now treats the data loaded from the CF Card as a ROM disk instead of a RAM disk. - Updated the assemblers to handle some more Z280 instructions used in HBIOS. - When building ZZRCC, checks have been added to ensure the ROM image is exactly 256K. The build defaults to 512K and that causes the ZZRCC disk image to be corrupted. This will stop the build if the user fails to specify a 256K ROM size.	4 years ago
Wayne Warthen	e6b9d2dcfd	Improve Z280 DMA Memory Copy The Z280 interbank memory copy uses DMA and did not properly handle scenarios where the source or destination memory range crossed over the banked/common memory boundary. It added a bunch of code, but it is fixed now. This seems to be required by CP/M 3.	4 years ago
Wayne Warthen	214ed54584	Miscellaneous - Fix build under Windows (credit to Dean Netherton for finding this). - Fix ReadMe.md file format to remove superfluous junk at top. - Improve RAM size detection (work in progress, not part of normal build).	4 years ago

Wayne Warthen	92399fe537	More CPUSPD Tweaks I know I said I was done, but I found a few more things I decided to tweak. Functionality is unchanged.	4 years ago
Wayne Warthen	b6aa769f12	Finalize CPUSPD The CPUSPD app is now considered stable and fully supported. I have added the application and the API's to the documentation.	4 years ago

Wayne Warthen	da71f225ca	ZPM3 Fixes - Fixes to ZPMLDR to make it functional with RomWBW. - Incorporate fixes from the Jon Saxton disassembly in ZPM3 itself. - Credit to Lars Nelson for finding the ZPM3 source (disassembly).	4 years ago
Wayne Warthen	ca67ee41c5	Fix CBIOS Bug - Corrects the dynamic disk buffer allocation routine in CBIOS and ASSIGN.COM. They had the DPB assignments inverted causing slightly wrong buffer allocations for RAM and ROM disks. Credit to Andrew Lynch for discovering this issue.	4 years ago
Wayne Warthen	3b345f8525	Add Linux Disk Imaging Doc	4 years ago
Wayne Warthen	dd3dfff172	DMA Driver Speed Handling - Updated DMA driver to leave system speed as it originally found it.	4 years ago
Wayne Warthen	891893c0e5	Fix DSD Driver - Dual SD support in sd.asm was broken for two cards when the SC126 dual SD card support was added. This should fix all scenarios.	4 years ago
Wayne Warthen	d5962681f1	UART Driver Update - Some newer/multi-port UART chips now use MCR:3 to activate the interrupt pin(s), otherwise tri-state. This update sets MCR:3 in all cases. - Added UARTDUAL config variable that enables detection of a dual UART chip at 0x80 for MBC platform. - Fixed a typo in TastyBasic Build script.	4 years ago
