I am particularly interested in microcontrollers with internal program RAM which can be set by the bus master on system startup. I once read a data sheet for one of Intel's microcontrollers (UPI?) which was designed to be accessed from an 80xx family bus, and to serve e.g. as a keyboard controller, but the version that I saw was ROM programmed. So far I don't know of any such devices whose program RAM can be set by the bus master on startup. Please e-mail responses; if I get useful feedback, I'll summarize. Thanks, Bill Newman newman@theory.tn.cornell.edu
