Unfortunately, Reprints of the SysEqu table from IM don't help. IM gives the vector to 4 registers of the SCC. IM uses 'strange' names (not Zilog) for these registers, though it seems clear that READ CTL is (Zilog) RR8. I need access to several of the Zilog registers ( there are more than 40!). If someone in authority knows that the address mapping is linear that would be enough. Thanks! Ira "I deny nothing!" - STIV
