Job duties include: * Software tool development: Assembler, simulator, debugger and utilities in C, C++, Perl and assembly code. * Intellivision software development: CP-1600 assembly language * Hardware development: PIC24H-based board design using Eagle * Firmware development: ROM / RAM / NVRAM emulation in PIC24H firmware * Development support: Assist 3rd parties developing titles for Intellivision * Reverse engineering * Sales Left Turn Only develops… Show more Job duties include: * Software tool development: Assembler, simulator, debugger and utilities in C, C++, Perl and assembly code. * Intellivision software development: CP-1600 assembly language * Hardware development: PIC24H-based board design using Eagle * Firmware development: ROM / RAM / NVRAM emulation in PIC24H firmware * Development support: Assist 3rd parties developing titles for Intellivision * Reverse engineering * Sales Left Turn Only develops hardware and software products for classic video game systems, currently focused on the Mattel Intellivision. Left Turn Only has produced a handful of video game titles of its own, and has developed custom hardware solutions and software development solutions that fuel the current resurgence of video games for the Intellivision platform. LTO's hardware appears under the Left Turn Only brand, as well as Elektronite. I developed LTO's software development platform (jzIntv / SDK-1600), along with LTO's first software titles. I also developed the JLP family of Intellivision cartridge designs, which provide flexible memory maps and innovative features such as non-volatile memory at a low cost point. I'm continuing to develop new hardware and software for this platform.
