The CPU runs with a 12 MHz bus and has a cool megabyte of memory split between RAM and EPROM. There’s a 44-pin IDE interface and two RC2014 expansion connectors. While $35 doesn’t seem like ...

Similar to RAM, a ROM chip works by storing data in memory ... To erase the data, the EPROM chip is exposed to ultraviolet (UV) light, which clears the charge from the floating gates, returning ...

To get around that limitation, all of the code is loaded into the microcontroller’s RAM. With a healthy 264 ... covered devices that could emulate an EPROM using 1990s era silicon.

256KB EPROM and 256KB RAM, swappable 128KB flash storage drives, integrated speakers and microphone, a touchpad, and the ability to receive eight AA batteries for an estimated 30-75 hours of autonomy.
