CALIBRATION RAM EXAMINE (Exerciser 02). This
routine allows the operator to examine the contents of 256
decimal locations, 00 (Hex) through FF (Hex), in RAM.
When entered, the Exerciser displays the contents of RAM
location 00 (Hex) on the top line of the CRT display. One
hundred and seventy calibration constants reside between
addresses 01 (Hex) and AA (Hex). Calibration constants
residing between 01 (Hex) and 6E (Hex) should have odd
parity as explained below. The remaining locations may be
of either parity. The readout display line has the following
format:
AA DDDD P
The format is defined as follows:
"AA" is the eight-bit address in hexadecimal notation.
"DDDD"
is the 14-bit word stored at that location (13
bits of data and one parity bit).
"P"
is a parity indicator for the data word: X indicates
even parity; blank is odd parity.
Pushing the upper or lower TRIGGER MODE switch will
increment or decrement the RAM address by 16 (10 Hex)
respectively. Similarly, pushing the upper or lower
TRIGGER SOURCE switch will increment or decrement
the address by 1 respectively.
