Photo 1a—In addition to providing a port for the eZ80F91 module, the eZ80Acclaim! evaluation board allows the addition of SRAM, a socket modem, and specialized application modules. There’s also a JTAG interface (light blue connector) and a ZDI target interface module interface (dark blue connector) tied to one side of the eZ80Acclaim! evaluation board. The application module fits over the male I/O headers. b—The ZPAKII is fitted with a serial and an Ethernet interface. After everything was configured and running, I found that I could disconnect the ZPAKII serial interface. The ZPAKII sits between the Developer Studio II and the ZDI target interface module, and is an integral part in the debugging and emulation processes. The ZDI target interface module is the module at the other end of the ZPAKII ribbon cable.
