4cbb74c033 Fixed two microcode bugs related to task switching behavior. Dance, StarWars and *SMALLTALK* work! 2016-03-09 16:05:45 -08:00

30ed445764 Fix for soft-reset emulator uPC and device reset; CopyDisk now executes correctly. 2016-01-11 16:16:05 -08:00

0cce77c842 Fixed S register addressing (many things now working!), tweaked display (mouse displays correctly in lowres mode). Added support for committing disk changes back to disk images (done automatically when switching disks or exiting). Repaired BravoX image. 2015-12-22 15:45:56 -08:00

3c8a64bac8 Ethernet implemented, fixed a bug in "mixed" double word stores (store followed by fetch rather than two stores). Fixed a few UI issues, fixed Reset behavior. 2015-12-17 16:11:03 -08:00

b13944c81c Implemented proper video timing, basic mouse support and fixed microcode RAM loading. MARTEST now passes with flying colors; more things are running. Suspect disk timing for other failures. 2015-11-19 17:41:16 -08:00

cbcfd2b47e Minor bugfixes, introduced a new timing infrastructure and moved DiskController over to it. Minor performance improvements; now running at 110% speed. Display timing is still too slow. 2015-11-17 16:09:50 -08:00

30ecfa6900 Support for CRAM reading/loading, SWMODE support. Rough debugger UI for viewing / disassembling microcode in ROM1, RAM0 banks (ugly). Minor performance improvements. 2015-11-13 16:50:18 -08:00

a689b7185a Fixed: Disk address (KADR) and Disk Data (KDATA) registers behave (more) correctly; in particular record commands hare processed properly and KDATA handles reads/writes more sanely. Fixed checksum calculation; due to above changes microcode now correctly validates checksums and boot progresses to read in an entire track's worth of data before dying with a "check failure" error. 2015-11-04 16:49:42 -08:00

39f077bf7a A few fixes to DNS<- behavior and some tweaks to the disk controller. Boot code is progressing further. 2015-11-03 16:21:12 -08:00

2918ede7ce Some fixes to emulator task dispatch functions, added Nova disassembler, nova instruction single-step and nova instruction breakpoint support. Penciled in DNS (Nova Shift) support in emulator task. Added skeleton for Logging. 2015-10-28 14:11:04 -07:00

3b29addb98 Disk sector reads now work correctly, and checksums are correctly calculated. Still feeding dummy sector data. 2015-10-23 16:07:07 -07:00

ea5a5f22ec Improvements to Disk Word Task. 2015-10-20 15:32:26 -07:00

ee7c7fb035 Implemented more Disk functionality, fixed bug in ACSOURCE dispatch in Emulator task. 2015-09-16 16:27:16 -07:00

08d6063def Refactored Task code into separate files for readability; added breakpoint support and basic Memory window to debugger. Initial implementation (mostly stubs) of Disk hardware and Tasks. 2015-09-14 11:27:16 -07:00
