### DESCRIPTION
THIS IS PLANNING 1st revision HARDWARE YET!!!
It is a first version, so it could be had a mistakes on board. Software for PIC is not wroted yet. I did not can guarantee that i make this hardware to it logical end, couse it DIY project, but i plan to make it.
WHATS IS PLANNING:
This is a display and keyboard board to simple DIY home computer.It could display three bytes (write to address from 0 to 2) or six user defined character on 7-segment 6 digit LED display.
Also it has a interface to HD44780 LCD (2*16 characters with CP-866 or KOI character tables)
It has a HEX keyboard or very simple ASCII keyboard
UART (TX only) with hardware flow control.
Baud rate generator for i8251 (300-19200bps)
Clock ticks out (1, 10, 50 Hz)
This device is maked for use with old soviet UT-88 computer.
It connected to them by use of i8080 bus with D0-D7 and A0-A3 lines. So, you can connect it to any computer with parallel bus.
Also it use ~rd, ~wr control lines. Based on PIC16F77 uC
### TECHNICAL DETAILS / COMPONENTS
PIC16F77 or PIC 16C77
