Current SmartIDE Code - Includes code to handle LCD display mapped @ 0xD1C0-0xD1C1, 
and initialization code for 2nd POKEY (@ 0xD21x), 2nd PIA (@ 0xD31x), and a 6522 VIA (@ 0xD32x).  
Source is configured to assemble and overlay an OS ROM image located at 0x4000-0x7FFF.  
This code assumes you have a stock Rev 2 OS ROM (free space from 0xCB65-0xCBFF) and do not want the international 
character set (0xCC00-0xCFFF).  There isn't much room left available with this overlay in place.
