Enthusiasts in the early era of home computer created miracles with relatively primitive chips at that time, while what can not be accomplished with Z80 or 6502 is often attributed to complex design based on logic chips and discrete components. Someone wants to know what these hackers can do with modern components that we take for granted.
Perhaps it will be like the smallest serial terminals of the current batch of home-made computers. The board is designed by [Augusto Baffa] and used in his baffa-2 self-made microcomputer, which is a rc2014 Z80 machine running CP / m. The terminal board is one of many enclosures inserted into the baffa-2 backplane, but it seems to be one of the few boards that take a shortcut to use modern microcontrollers to complete its work. The board of directors is equipped with a pair of atmega328; One handles serial communication with baffa-2 backplane, and the other is responsible for running VGA interface. The card also has PS / 2 keyboard interface and supports vt-100 ANSI escape. The following video shows how it works with a 17 inch LCD display at the original 4:3 aspect ratio.
We like the easy-to-use working mode of this terminal card, and we also like the appearance of baffa-2 itself. We also found an imsai 8080 and an Altair 8800 in the video background. We’d love to know more about this.
