CRISS CP/M - Modern DIY CP/M Computer!
CRISS CP/M is a 21st-century CP/M single-board computer based mainly on AVR microcontrollers. The CPU is a 20 MHz ATMEGA1284P, which imitates a 4 MHz Z80 through machine-code emulation. A pair of ATMEGA328s run the peripheral controller and a VGA output, so the CRISS can be used with modern monitors. Standard image is monochrome green-on-black, looking instantly familiar to users of Kaypro's, Osborne's and other contemporary CP/M machines. But for new programs additional circuit based on the ATTINY84 MCU provides 8 basic colors!
Software is loaded through an SD card that holds floppy images. The CRISS can directly run programs written for the Kaypro II and Robotron 1715 computers, although other platforms can be supported as well with a software upgrade.
Housed in a neat little case (13x10cm PCB size), the CRISS can communicate with standard PS/2 keyboards and serial printers. Even an Ethernet port is provided for those willing to experiment with network connectivity (a rare feature in the 1980s).Join CRISS worldwide community at Discord!
Really cool? But it is not the end of the list, there are also available:
CRISS CP/M has its own settings, but it can emulate other hardware platforms and terminals emulation, for now it supports Robotron 1715 (RU and EU versions), Kaypro II/ADM and TRS-80!
Power supply: AC 120-230 V 50-60 Hz. SIngle box 140x110x35 mm size, PCB size 100x130 mm.
And what absolutely unbelievable: only DIP components! Anyone can solder it, detailed video how to do it available!
