+Skeleton driver for Cross Products Ltd. DASH4 Debug Adapter.
+
+DASH4 is the hardware debug adapter of CodeScape development environment for the Hitachi SuperH family of
+microprocessors.
+It's an intelligent debug pod that offers a complete low-level debug capability. The DASH4 uses the JTAG
+interface to communicate with the target at 1.5 Mbytes/s via the Hitachi User Debug Interface (HUDI)
+built-in to the SH7750. The DASH4 connects to the host computer via Ethernet to allow high-speed
+communications with the debugging software.
+
+The CodeScape Development system encompasses both software tools and hardware interfaces to provide
+development support for Hitachi SH microprocessors from initial low-level system troubleshooting through
+to the development of complex applications in C++.
+
+It came bundled with the Altera Design Software for PCs "Quartus II":
+https://archive.org/details/altera-quartus-ii-version-2.2-manuals-software/
+
+Also, it came with a MemoHASP-1 parallel port security dongle labeled:
+"MemoHASP-1 R3b CCYRW NA 23967", "HASP ID= 75BB4C39", "SH4".
