Under normal operation without drives spinning the SAM consumes the least of any of the ZX derived machines! In fact the greediest component in the SAM is the z80B CPU! If that was replaced by a CMOS z80 that'd probably reduce the consumption by almost half! As for robotics control or smart robots etc the SAM motherboard is near ideal! To run it only requires the +5Volt supply and an I/O pcb could be designed that fits into the second drive plug and programs loaded via the MIDI/NET or TAPE. Keyboard can be attached or removed whilst online (carefully of course;) 256k of on-board RAM which could be expanded to 512k with a slight reduction in robustness whilst outside the case... +12v supply can be switched on or off whilst online as it only powers the discrete 1 transistor buffer of the composite video output. So can be used to setup the program and then removed to let it get on with it! Just a thought but with an 8bit 8channel ADC chip on a I/O pcb with normal digital I/O ports too it would be possible to have respectable speech recognition and therfore control of a SAM controlled robot! Using Machine code quite amazing things *should* be possible! Johnathan. ...
