Believe it or not, Motorola has a BBS that will download a FREE 6805 cross-assembler. They also sell one part # M68HXBRASM for $190. I don't know what the advantages of the commercial version are. I have used the precursor to the freebie on VAX and SUN systems. It is written in C and works quite well. You can reach the BBS by calling (512)891-FREE. I believe it's kept pretty busy during business hours, so you might have to try a few times. It also has lots of free software for the 6805 family as well as 68HC11, 6800, 68000, 68332, etc. There are math packages, an HC11 C-compiler, and even a 68705R3 simulator! No charge except the long distance. The old Motorola databooks I have show schematics for building a simple programmer board. It bootstrap programs from a 2532 32k EPROM, so you would need an EPROM programmer. Better yet, Motorola's distributors carry a board called the M68HC05PGMR for $168 MSRP. If you want to build it up yourself, Motorola will ship you a FREE PC board and documentation. You just supply the parts and labor.
