Hi,
I just recently got a Franklin/Rolodex RT-8214 'cause I thought it might be fun to hack around with. You can download Franklin supplied extra programs through a PC USB cable so I thought I might try my hand doing my own. Unfortunately, there doesn't seem to be any sort of developer's kit available from Franklin so I've got a bit of reverse engineering on my hands.
The unit uses the Sitronix ST2202 processor. Unfortunately, aside from a processor manual (which only describes the modules and control registers) there doesn't seem to be any further documentation on programming it. Find the manual at
Can anyone suggest resources for programming information for this CPU?
Thanks very much,
Jos'h
