Simulating a Java / Forth Virtual Machine - CH
Ting "I have a JVM / FVM synthesized on the Quartus II IDE, but I do not
have a FPGA kit to test or verify its operation. To test the outer interpreter,
I implemented a soft UART consisting of a Terminal Input Buffer and a Terminal
Output Buffer residing in the main memory. It runs at the speed of the master
clock for ease of simulation.

ForthBox Update - Samuel A. Falvo II Work
on the Kestrel-1 redesign continues, albeit slowly. Since I last gave an
update, the development emulator is now working and the subroutine-threaded
Forth-subset cross-compiler seems to be working as well, but more testing is
required."

development emulator for the ForthBox / Kestrel-1 Finished Product:

lib65816 library which powers the above emulator:

development bootstrap cross-compiler I intend on using to port Forth to the
ForthBox:

A Forth Challenge for December - Bill
Ragsdale "Compute (approximately) 100! (100 factorial) using Forth's
integer math, using your favorite method and, if available, check your result
with floating point math. For extra credit, compute 100! exactly. For even more
credit, how would you calculate the number of trailing zeros?"
