The chip, along with the rest of the TI-99/4A has been fully emulated in JS in this fantastic project you can run in the browser. It even has a debugger and all the original cartridge software, too.

There's no better or faster way to experiment with a TI-99/4A today. Besides the great hardware emulation, a huge collection of the software released for the platform is available right there on the site.

And you can map emulated disks to Google Drive folders. It's disturbing how much I enjoy writing TI-BASIC programs with half-way realistic data files I stuffed up on the GDrive.
