This is my first attempt to create my own TI99/4A emulator which I can use for
testing and debugging. I have used this emulator in Windows-98, Windows-NT,
Windows 2000 and Windows XP and I don’t expect any difficulties in other
versions of Windows but you never can tell.

- A maximum of 64Kb of RAM. The TI99/4A ROM is also loaded at this space.
