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	9100f199b1	Z80-Retro SD Card Support (Alan Cox)	3 years ago
Wayne Warthen	bcc50a31a9	Fix SIO Ports in Z80R Mode	3 years ago
Wayne Warthen	c891ba2bad	Support Z80-Retro Platform Code provided by Alan Cox	3 years ago
Wayne Warthen	f346209c82	Front Panel Switch Support	3 years ago
Wayne Warthen	2681b84a20	Finalize v3.2.1	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	51d962aeab	Finalize v3.2.1	3 years ago
Wayne Warthen	5f36cf9a12	Fix TUNE Delay Factor Handling	3 years ago
Wayne Warthen	7563863be2	DOS/65 Refresh - Refresh WIP files of DOS/65 from Dan Werner - Another tweak to SURVEY - Regen PDF docs	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

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
Wayne Warthen	5073a9c506	Fix for Issue #324 ZPM Named Directory Handling Error Credit to Jose Luis for discovering this bug and bringing it to my attention. The fix is a small patch on top of the patches previously applied from Jon Saxton. See the ZPM3 directory in Sources for more information.	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	7d19d3e403	More Cleanup	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
