Wayne Warthen	5d34a5c5d5	Miscellaneous - Implement SHOWHEX functions in ICM and PKD drivers - Improve DSKY common routines in HBIOS - Include key CP/M 2.2 programs in NZCOM floppy image	3 years ago
Wayne Warthen	f8c800e527	Create DSKY Driver Framework Added a new driver category for DSKY (Display/Keypad) devices. Existing DSKY devices were converted into drivers ICM and PKD. These devices were previously DSKY and DSKYNG. This removes substantial code duplication and recovers significant space in romldr and dbgmon.	3 years ago
Wayne Warthen	5457a7e7fd	Improve OS Boot Drive Assignment - Modified the Disk Device function call (DIODEVICE) to provide new attributes related to disk size and removability. - Leveraged API change to allow handling drive assignment differently depending on ATAPI vs. ATA interface.	3 years ago
Wayne Warthen	0475f5e853	Minor Cleanup - Update FPLED port values for some configs - Fix Linux/MacOS build for new disk images	3 years ago
Wayne Warthen	8747ec8d02	Clean-up of ATAPI Support - Improved media handling and error reporting.	3 years ago
Wayne Warthen	abd939625f	Support ATAPI in IDE and PPIDE Drivers - Support is limited to 512 byte sectors. So, devices such as ATAPI Zip Drives will work. CD-ROM devices will not because they use a larger sector size.	3 years ago
Wayne Warthen	1f526d440a	Add WDATE Command, Final PPA/IMM/SYQ Driver Cleanup - Added WDATE command courtesy Kevin Boone. See https://github.com/kevinboone/wdate-cpm for more information. - Final cleanup of PPA/IMM/SYQ drivers including CPU speed compensated timeouts.	3 years ago
Wayne Warthen	84374c86e6	Cleanup and Optimizations for PPA/IMM/SYQ Drivers	3 years ago

Wayne Warthen	1c411f5552	Add IBM Standard Parallel Port Support to IMM Driver	3 years ago
Wayne Warthen	364e48a5d3	IMM Driver Cleanup, PPA Driver Skeleton IMM Driver has rational timeouts now. It also lights the MG014 LED during activity. The PPA skeleton just attempts to determine if the PPA interface is present. It does not attempt any I/O.	3 years ago
Wayne Warthen	63cb89dcfc	Preliminary IMM Driver (Zip Drive) Thanks to Alan Cox for inspiring this. Much of the code was usurped from Fuzix.	3 years ago
Wayne Warthen	6e316b46f0	Document p-System Volume Management Python Script - Andrew Davidson created a nice Python script to extract/insert p-System volumes from/to disk images. Added a reference to his website in the p-System ReadMe.txt file.	3 years ago
Wayne Warthen	3f23396536	Support for MG014 RCBus Parallel Port Module	3 years ago
Wayne Warthen	c628ba10f2	Workaround Z280 CPU Bug for LZSA2 The LZSA2 decompressor invoked a known Z280 CPU bug. A small modification to the code resolves this.	3 years ago
Wayne Warthen	9358299f14	Z280 Workaround for VGARC Z280 is having an issue with OTDR instruction when loading the font for VGARC. For now, the use of OTDR has been eliminated.	3 years ago
Wayne Warthen	d445c4a015	Disable LZSA Compression for Z280 - The LZSA2 decompressor code is failing mysteriously on Z280 CPUs. I have simply disabled it in the Z280 primary configuration file.	3 years ago
Wayne Warthen	e32002545b	VGARC Improvements, Doc Fix - Added ability to enable VGARC and front panel in default config without I/O conflicts (does not support having both types of hardware present at the same time). - Fixed documentation error in issue #345 reported by @MorfeoMatrixx.	3 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	9f71fe05aa	Cleanup IDE and PPIDE drivers - The use of hardware reset has been improved such that it is generally only used at initial boot up. - Minor improvements to CF card detection and initialization. - Implement a simple wait mechanism to accommodate the startup time of the RC2014 SD Pico module. - Front panel I/O port for SC series of systems has been moved to 0x00 which is consistent with all other systems and avoids some I/O conflicts.	3 years ago
Wayne Warthen	ad3c533145	Fix IDE Detection on Spinning Disks Prior improvement to IDE device detection broke detection of spinning hard disks. IDE registers cannot be used prior to device init completion (spin up). Not a problem for CF, but special steps required to ensure devices are fully initialized before register testing.	3 years ago
Wayne Warthen	e43a939f54	Improve IDE Device Detection Per issue #343, some systems could initially detect a non-existent IDE device which would cause a long time-out. This should resolve the issue.	3 years ago
Wayne Warthen	e5b7409f44	Support Per-floppy Device Drive Types - Floppy devices are now configured per-device so that each floppy drive can be different (e.g., first floppy is 3.5" and second floppy is 5.25"). - Removed need to use termination signal on floppy sector I/O. Addresses issue #318	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
