Caution: Lithium batteries have a low internal impedance. Do not place the
populated board on a metallic surface, in case you short the solder pads on the
bottom side. It's recommend that you put an insulating sheet under the battery
area, to guard against accidents.

Terminal Settings
The default terminal set-up is 9600bps, 8 bits, no parity, 1 stop. The primary
terminal ("console" to CP/M) connects to P4. Use a null-modem cable, the
nulled pigtail described in section 2.1.2, or short pins 1,6 and 7 of P4 together.
This is necessary to force the modem control lines active, without which the
serial port will not operate.
4.3
Disk Drives
The board can run a variety of PC-AT type 3.5" drives, "out of the box".
Specifically, the drives should be jumpered with DS1 active (as is normal in a
PC-AT). There appears to be little standardisation regarding the location of
the connectors on disk drives. For example; the location of P9 will give a direct
connection with Teac drives, but is awkward with Panasonic ones.
