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	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	c157d52c1d	More Cleanup This check-in includes some refactoring of the configuration files.	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	71a8b2b177	Finalize p-System Implementation - Implemented Extended BIOS functions - p-System slices moved into partition	3 years ago
Wayne Warthen	979e763739	Introducing p-System IV.0 for RomWBW A full implementation of UCSD p-System IV.0 for RomWBW. Derived from the official Z80 Adaptable p-System. My first real programming was on this system. So many memories...	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
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	94c32c9fd0	Mostly Build Improvements - ROMSIZE is now a configuration variable instead of a command line parameter. - Added CP/M license information based on new email from Bryan Sparks.	4 years ago
Wayne Warthen	3b0951f6d5	MFPIC I/O Base Update - Update MFPIC related I/O ports from $4x to $1x. The default base address was changed to avoid conflicting with the default I/O range of $40-$7F on ECB Z180 boards.	4 years ago

Wayne Warthen	11ea0c8c27	Add Speaker Beep Added a generic routine in HBIOS to play a beep sound on the first available sound device. Implemented the beep in the ANSI and TTY terminal emulators.	4 years ago
Wayne Warthen	b82ff327cf	CBIOS Fixes for UNA Development in the dev branch on CBIOS had broken basic UNA functionality. These fixes seem to correct the problems. A full regression test of UNA has not yet been performed.	4 years ago
Wayne Warthen	44b17ccc3a	Improve Centronics Compatibility - Renamed Centronics driver from "CEN" to "LPT" based on input that LPT is the more recognized name for IBM compatible Centronics interfaces. - Modified LPT hardware detection to be more generic (no longer depends on MBC-specific hardware implementation). - Fix to CPU speed display for SBC v2 (004 and above) speed selection mechanism.	4 years ago
Wayne Warthen	b2e1294452	Correct AY38910 Off By 1 Octave Issue I think this update corrects a long-standing issue in which the AY38910 driver played notes off by one octave.	4 years ago
Wayne Warthen	d39f0201f4	Bootable QP/M Disk - Put a preconfigured image of QP/M on the system tracks of the QP/M disk images. - Minor adjustment to dbgmon.asm for compatibility with UNA.	4 years ago
Wayne Warthen	a62f5805ca	Add BOOT_DELAY Configuration Variable Some systems use terminal devices (Raspberry Pi, etc.) that take a few seconds to be ready to display console text. The BOOT_DELAY setting can be used to introduce an arbitrary delay (in seconds) in the boot process just prior to text output. This can be used to avoid missing some of the boot messages.	4 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
Wayne Warthen	0e32dd58fa	Update version files - Missed the version files in prior check-in	4 years ago
Wayne Warthen	b98ee17e14	Plumbing for uPD7220 GDC Driver	4 years ago
Wayne Warthen	4a88e0bcae	Improve Z180 Variant Handling - There were several places that RomWBW was making incorrect assumptions about what the older Z180 CPUs could do. These have been corrected.	4 years ago
