Fulcher, John, Down-line loading on hero robot, Department of Computing Science, University of Wollongong, Working Paper 84-13, 1984, 39p.
Expansion of ET-18 (Hero 1.0) Educational Robot in order to provide down-line loading capability from the Unix time-shared operating system is described. This expansion has also enabled up-line saving of programs from Hero to Unix. These facilities are implemented in EPROM form (2716) in the optional ROM socket on Hero's CPU board. The program stored in EPROM is essentially the same as the Utility EPROM used on the expanded ET-3400 Microprocessor Trainers in the Department's Microcomputer Laboratory, with minor modifications to run on Hero. As a direct result of incorporating these facilities into Hero, the Unix down-line load program 'dll' has been upgraded (to allow for up-line save), and an r-file for the Unix general-purpose cross-~ssembler 'mac' has been written to allow for the use of Robot Interpreter commands (Hero utilizes unused M6800 op. codes as commands when running in its 'Robot Interpreter' mode).
