How must the board be wired?
Four active signals (RxD, TxD, CTS and RTS) must be connected and the RESET line of the AT90S2313 microcontroller (pin 1) must be wired to ground (pin 10 on the microcontroller, pin 5 on the RS-232 connector, or pin 1 of the card edge connector), and power must be supplied to the board. There are two jumper wire pads on the production version of the board. One is almost under the microcontroller, and it can remain closed at all times. The other is located next to the cassette port connector. This RESET switch of the AT90S2313 is the jumper that must be closed in order to upgrade the firmware.
