If you've been playing with computers for a long time like i have (by a "long time" i mean 30+ years) you're going to love this. You can run Windows 1.01 in your browser You can run the basic installed programs and everything. Even click Ctrl+Alt+Del to reboot into DOS and play with all the commands and programs that came with it.
AND! If you remember how to code in BASIC or BASICA, you can write and execute your own programs! I tried it. Was very awesome. Don't forget to change to SCREEN 1 to use the 4 color graphics! There are even a few programs on B: you can run in BASICA. Maybe you remember that game Donkey where you were a racecar and had to dodge donkeys in the road? Good times...
