Id like to play it just because this guy is actually living in that world for 19 years and its facinating
Garmin eMap from 1999 is probably the second closest.
Tried to get it working a few years ago, but couldn't get it to display on the TV. Wasn't sure if it was even powered on because the thing has no lights on it, it was prior to LEDs being commonplace. I didn't have an oscilloscope or the skills to debug it.
Having just finished off 4th year embedded systems I'm probably a bit more qualified to debug it now than I was in high school.
And now I feel old because that was my first computer too.
:o. Thanks, I've learned something new today! I didn't knew the cartridges had battery-powered memory.
