Win994a Simulator Description

Win994a is a TI-99/4A simulator written by Cory Burr that installs and runs in the Windows environment. It was written to simulate the TI-99/4A, not to emulate it perfectly. General Functionality: 1. Boots and runs all console ROM and GROM based functions including console BASIC. 2. CRU bits for the keyboard are implemented; some CRU bits for the Disk Controller and RS232 Interface are implemented. 3. TMS9918a video chip functionality is fully implemented. 4. TMS9919 sound chip functionality is fully implemented. 5. TMS5220 speech synthesizer chip data transport is fully implemented. Speech text is displayed in a scrolling marquee, in addition to being spoken. 6. Full floppy disk and disk controller functionality. 7. Full cassette tape functionality for CS1. 8. 32k Memory Expansion supported. 9. PIO and RS232 ports are supported, but using a different method than the original TI99/4a. 10. Support for two external joysticks, or simulates one joystick input using numeric keypad. 11. Runs over 200 cartridges correctly. Cartridges that depend on non-implemented CRU bits or non-documented video chip operation will fail
