You all must have seen some good homemade stuff that I already have told you but this one is my favorite.

Blake has built his own computer from a scratch and has named it Z80 Microcomputer.

He began the project in the spring of 2006 and has just completed his project.

The current specifications of the project are:

� 2MHz 8 bit Zilog Z80 processor

� 56 KB static RAM (7 x 8k x 8)

� 8 KB EEPROM

� 1 Mb Flash Memory "hard drive"

� Interrupt controller with 8 interrupt levels

� 20 character x 2 line backlit LCD with contrast control

� RS232 serial port

� 2 programmable timers

� Programmable beeper

� 8X DIP switch and 8X LED's for general purpose I/O

� Strobe button for clocked input from the DIP switches

This is simply great Blake!
