reZet80 SENTINEL

The reZet80 SENTINEL is a stand-alone computer system that could have been built in the 80s.
It features the powerful Z80, 128 KiB of RAM, 4 KiB of ROM, a 23-key keyboard and LCD displays in various resolutions. I only use technologies that were available in the 80s for this project.

Note: I use a 16x2 instead of a 16x1 LCD display because the one I have (extracted from a Yamaha FB-01 sound generator) only features a single HD44780 controller chip without an extension driver so it's actually an 8x2 display. Programming the display is a little bit trickier as you have to switch the line after the 8th character. Please check my reZet80 DEV project on how to program such a display if you are interested.
