Would be cool to have a system that you turned on, and no loading occurred at all. The processor just executes current software in RAM. RichThe end result is that you get the "instant-on" effect and can pick up that game of Sabotage from last week.Does anyone have enough electrical and RAM chip knowledge to comment on the realisability of this idea?
Nope, that would never work with DRAM. That approach could be used with older (typically S-100) systems that used SRAM. -michael 8-voice music synthesizer using NadaNet networking! Home page: http://members.aol.com/MJMahon/
