For five or ten US dollars (or free, mostly) you get an easily hacked micro with all the lines available on the expansion connector and a decent built-in BASIC if you need it. Plus 8KB of available address space in the 8-16KB region which is perfectly suited to add-ins such as NVRAM or, my favorite, a disk operating system in ROM. Glen 0/0
