Does the SP’ACE support a software-programmable RT address?
A. There are two different versions of the SP’ACE: (1) the BU-61582XX, for which the RT address is hardwired; and (2) the BU-61583XX, for which the RT address may be programmed by means of software control. To make the BU-61583’s RT address software programmable, you would need to connect RTAD4-RTAD0 to D5-D1, and RTADP to D0.
