This release is aimed at supporting user-level exceptions by allowing user code to modify the return stack pointer. It does so by replacing the byte variable RDEPTH by a 'virtual' variable, i.e. the value of the A register after the EVRDPTH subroutine has been called. The whole process is not fool proof though and remains to be perfected. Only 9 bytes of EEPROM space are left at this point.
The CompactFlash image has been updated to include the latest incarnations of Pacman for the VT420/VT340.
