Wayne Warthen	c891ba2bad	Support Z80-Retro Platform Code provided by Alan Cox	3 years ago

Wayne Warthen	b5437c56e9	Suppress Serial HFC During Boot If serial hardware flow control is enabled, but not working, then a system will appear dead because it won't send any data to the host computer. This change suppresses hardware flow control during boot just to ensure that boot messages can make it to the serial console. This will only be effective for serial interfaces that support dynamic management of HFC.	3 years ago
Wayne Warthen	f640630a06	CPU Speed Calc Tweek - Exit CPU speed detection routine earlier if the clock is not ticking. - Fix minor regression in the SBC_simh.asm config file.	3 years ago
Wayne Warthen	53e201bd28	Handle Overflow in CPUSPD Edge case where the CPU speed detection routine would overflow in a fast emulator and return a speed of 0.000 MHz. Modified to fail back to the default CPU speed from the config file if an overflow occurs.	3 years ago
Wayne Warthen	6e34de0e02	Cosmetic Minor cosmetic changes in source.	3 years ago
Wayne Warthen	98a33b8b50	CTC & CPU Speed - Revamped CTC detection algorithm hoping to handle problem XRBR is having - Fixed typo in dynamic CPU speed test that caused it to not be properly recorded/reported (credit XRBR) - Allow use of DEL/RUBOUT keys as backspace in ROM Loader and Debug Monitor	3 years ago
Wayne Warthen	8aebaab3fe	Fix SURVEY.COM (again) - Previous fix to SURVEY.COM port survey broke the memory survey. Everything should be OK now. - Regenerated documentation.	3 years ago
Michal Potrzebicz	74a8283bba	Fix default ZETA V2 SBC configuration - Set the default CPUOSC to 8MHz (default value in the project's documentation), updated the User Guide - Set the FDD controller to ZETA2 - regression introduced in `bd664c3`	3 years ago
Wayne Warthen	82c53bd20b	Update to Small Computer Z50 Configurations - Improve adherence to Z50 standard.	3 years ago
b1ackmai1er	0d0f5fb182	Update dma.asm cp/m fails to boot with the dma driver included but no dma hardware installed. This is because the default "dma_fail_flag" indicates that the dma is good to go. But in safe mode the dma initialization never takes place to find no dma and set this flag, so the memory driver hangs. This change is to make the default status of the flag the failed state so the memory driver will fallback to software in recovery mode.	3 years ago
b1ackmai1er	70d3f54834	Some driver documentation updates and corrections	3 years ago
Wayne Warthen	b27e14826a	Allow Inaccurate CTC Divisor for Tick Frequency See Issue #327. This change makes an inaccurate CTC divisor a warning instead of an error. Credit to Phillip Summers.	3 years ago

b1ackmai1er	e7ab778929	Slightly better handling of low HBIOS heap memory CBIOS reports *** HBIOS Heap Overflow, when the HBIOS is big (i.e. lots of included drivers) Trigger build failure when CCP will not fit in heap. Slightly more informative CBIOS error message	3 years ago

Wayne Warthen	2f3fb51884	More Cleanup - Tweaks to SURVEY and PORTSWP to improve port detection accuracy and handle Z280 better - Recover a lot of wasted space in dbgmon using a few built-in utility routines instead of entire util.asm - Improve the (D)evice command in romldr to use the HBIOS routine which is much more complete and saves space	3 years ago

Wayne Warthen	cd161067db	Update CF Card Detection In the IDE and PPIDE drivers, a CF Card is differentiated from a Hard Disk using the first word of the result of the IDENTIFY DEVICE command. The value 0x045A was recently added because it was seen from a CF<->SD Card adapter. However, the value has now been seen from a spinning hard disk. Since the value is ambiguous and not defined in the CF Card specs, I am removing it from the list of CF Card signatures. Credit to Mark Elkin for identifying this and helping me track it down.	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	16475fe408	Audio Driver Cleanup Resolved some consistency issues between the AY-3-8910 and SN76489 audio drivers.	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	2271c086b5	Minor IDE/CF/SD Disk Handling Updates As suggested by Laszlo Szolnoki, I have added an additional CF Card signature to the IDE and PPIDE drivers. He also pointed out a deficiency in the disk size printing which has been addressed.	3 years ago
