Classic99 to emulator mikrokomputera Texas Instrument 99/4A z początku lat 80, jako ciekawostkę warto podać, że była to pierwsza konstrukcja przeznaczona dla domów opartą o 16bitową architekturę, która z kretesem przegrała tocząca się w latach osiemdziesiątych wojnę cenową z innymi komputerami domowymi.

- Update 'known issues' for Diagnostic Cart -- Checkerboard test fails when the disk system allocates VRAM. No fix intended - in the future you'll be able to disable the disk controller. If you need it now, use the debugger on the title screen to set >8370 to >3FFF
- Fix resource leak in Heatmap that would eventually lock up the emulator
- Simplified VDP address updates based on hardware observations
- Verified VDP prefetch and address register behaviour against hardware
- fixed GRAM write address (tesed against RXB's CALL POKEG)
- verified GROM address and prefetch behaviour during writes against hardware
Classic99 is a freeware TI-99/4A emulator for Windows 2000 and up.
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively.[2] The TI-99 series competed against home computers such as the Apple II, TRS-80, Atari 400/800, and VIC-20.[3]
Based on Texas Instruments's own TMS9900 microprocessor originally used in minicomputers, the TI-99/4 was the first 16-bit home computer.[4] The associated TMS9918 video display controller provides color graphics and sprite support which were only comparable with those of the Atari 400/800 released a month after the TI-99/4.
