TALLY PARAMETERS
AVTALS $1060
Each of the top four bits of this byte should be set to 1 if the corresponding tally is connected. The
bits are defined as:
bit 4 MACHINE IN RECORD
bit 5 MACHINE RECORD ENABLED
bit 6 END OF TAPE
bit 7 GENERAL USE
TALINV $1061
If a connected tally is active low the corresponding bit in this byte should be set to a one.
FLSHTL $1062
If a connected tally is expected to flash for a required function then the corresponding bit in this byte
should be set to $01.
FLSHPRD $1063
display : FLSHPR
If any tallies are expected to flash then this parameter should set the flash period (approximately)
measured in 20ms steps.
NEGTAL $1064
The tally interface is usually expected to work from a positive voltage source. If a machine works
from a negative voltage then this parameter can be set to non zero to configure the inputs to work in
this way.
SERTAL $1065
A value of $01 in this parameter indicates the tallies come across the serial link. A value of $02 does
not use the serial record tally. A zero indicates the usual parallel tallies.
EOTACT $1066
This parameter determines the action of the ES/2 when an end of tape tally has been received.
Non-zero will force the ES/2 to go OFF BUS. Zero will cancel all processes and stop the machine
without taking the synchroniser OFF BUS.
RESERVED $1067
The following parameters determine idealised tallies to report to the kernel. The idealised tallies are
defined as follows;
bits 0-3 are unused
bit4=1machine is in record
bit5=1machine is record enabled
bit6=1machine is out of tape
bit7 = 1 general use defined for specific machines
