Rev0 KIORC Engineering Change for 32x16KB banks

This engineering change is needed to convert rev0 KIORC pc board to emulate memory bank scheme of RC2014 512K RAM/ROM board

5K pullup resistor for channel B receive; VCC to one terminal of 5K resistor, pin 3 of channel B serial connector to other terminal.
RTS handshake to channel A; RTSA (KIO pin 29) to pin 1 of channel A serial connector.
RTS handshake to channel B; RTSB (KIO pin 14) to pin 1 of channel B serial connector
KIO clock out connect to Channel A & B transmit and receive clocks and Clock 1 and 2 trigger inputs; KIO clock out is already connected to Channel A & B transmit and receive clock. Clock 1 and 2 trigger inputs are pin 73 and 74 of KIO which is connected to pin 4 (TXCB) of KIO.
KIO's ASTA and ASTB need to be pulled up; connect KIO pin 61 (VCC) to one terminal of 4.7K resistor, connect the other terminal of the resistor to pin 44 and 46 of KIO
Ground KIO's DCDA and DCDB, pull down KIO's CTSA and CTSB; connect KIO pin 10 (GND) to KIO pin 8(DCDA), pin 7(DCDB); solder 0603 1K resistors between pin 6 and pin 8 of KIO and again between pin 7 and pin 9 of KIO thus pulling CTSA and CTSB to ground through 1K resistors.
