16-bit bi-directional address bus.
For 64K RAM versions, this signal is always configured as address
line A15 (MSB). Refer to the description for A11-A0 below.
For 4K RAM versions, if UPADDREN is connected to logic "1", this
signal operates as address line A15.
For 4K RAM versions, if UPADDREN is connected to logic "0", this signal
operates as CLK_SEL_1. In this case, A15/CLK_SEL_1 and
A14/CLK_SEL_0 are used to select the Mark3 clock frequency, as follows:

A10
For 64K RAM versions, this signal is always configured as address
line A14. Refer to the description of A11-A0 below.
For 4K RAM versions, if UPADDREN is connected to logic "1", this
signal operates as A14.
For 4K RAM versions, if UPADDREN is connected to logic "0", then
this signal operates as CLK_SEL_0. In this case, CLK_SEL_1 and
CLK_SEL_0 are used to select the Mark3 clock frequency, as defined
in the description for A15/CLK_SEL1 above.

LOGIC “1”
A13
B10
For 64K RAM versions, this signal is always configured as address
line A13. Refer to the description for A11-A0 below.
For 4K RAM versions, if UPADDREN is connected to logic "1", this
signal operates as A13.
For 4K RAM versions, if UPADDREN is connected to logic "0", then
this signal MUST be connected to +3.3V-LOGIC (logic "1").
B10
A12 /
RTBOOT
A12
A9
For 64K RAM versions, this signal is always configured as address
line A12. Refer to the description for A11-A0 below.
For 4K RAM versions, if UPADDREN is connected to logic "1", this
signal operates as A12.
For 4K RAM versions, if UPADDREN is connected to logic "0", then
this signal functions as RTBOOT. If RTBOOT is connected to logic "0",
the Mark3 will initialize in RT mode with the Busy status word bit set
following power turn-on. If RTBOOT is hardwired to logic "1", the
Mark3 will initialize in either Idle mode (for an RT-only part), or in BC
mode (for a BC/RT/MT part).
