Scott Baker has a nice write-up on building a Zeta v2 single board computer designed by Sergey Kiselev:

A few of the features of the Zeta 2:

• 512K Flash Memory, allows CP/M to be booted from Flash, and mounts Flash as a CP/M disk including many tools (assembler, editor, …)
• 512K Flash ROM, can be used as RAM Disk. Supports battery backup.
• 16550 UART provides a single serial port
• 8255 PIO supports up to three 8-bit serial ports
• Dallas 1210 Real-Time Clock
• WD37C65 floppy controller, easily supports 3.5″ PC Floppy Drives
