You should just be able to see FIGnition's @ symbol.
FIGnition's firmware has two major processes, a background task for generating video and
a foreground task for running Forth programs and interacting with the user.
The main thread of execution is as follows [Fig 8.4]:
Start Forth Virtual Machine:
Init the Instruction Pointer (IP) with Forth ROM Boot address. Re-
set the return and data stack pointer. Start SRAM reading from IP
Execute Forth:
IP<$8000?
At this point Forth is being executed from the Forth ROM. Its execution path starts at cold
