Download and unzip these into the same directory as the ALDL program to allow execution, modification, and recompiling:
Run-time BASIC engine: brun45 (you need this to run the ALDL program!)

Shareware for handling serial communication: qbser320 (serial routines required for compilation)
QuickBasic 4.5 Basic compiler (off-site link): qb45.zip (compiler needed to change program)
(If the qb45 link dies, just search internet for filename, it's out there.)

Remember: You'll need at least brun45.exe and E6B004.zip to run the program.
