Description

I would like to show you my new update to my C64 project. Shortly speaking it IS portable, battery powered C64 personal computer. I am a big fan of the C64 device. My coding begun on this device. I have one C64G device which I will modify a lot :) and I will post here a description of my work progress. So what we have now? SD2IEC - I made it myself. Mini LCD screen - Simple small rear view car LCD screen Build-in stereo amplifier with nice speakers Stereo SID - I made it myself. C64 original ROM and JiffyDOS OS with OS switch that auto reset on change. 12V DC input - I can power my device using any common 12V 2A power source or RC Li-Poly battery. Last days I do another round of upgrading my C64. I installed two pulse converters to get 5V and 9V DC to power my device. I decided to use DC to DC converters because I planed to use battery to power the device and I don't want to loose any energy from it. I added 12V power socked and RC Li-Poly battery socked. My C64 is fully portable device now. Common 2200mAh RC battery is enough to power C64 for 1.5 hour. To protect Li-Poly battery from discharging it to low I added simple RC voltage monitor that will buzz if voltage is below 3.3V.
