NCR Decision mate slot bus and module emulation
|

|
||||
From the NCR System Technical manual:
|
||||
|
||||
"The lower part of the controller board contains the I/0 bus together with
|
||||
seven user-accessible connectors. These connectors are identified on the board
|
||||
as J1 through J7 (reading from left to right), and correspond to the seven slots
|
||||
(numbers 1 through 7) at the rear of the cabinet.
|
||||
Position J1 is reserved for the connection of any one of the memory expansion modules
|
||||
(K200, K202, K208).
|
||||
Position J7 is reserved for the connection of either the diagnostic module (K220),
|
||||
or the customer-installable 16-bit processor module (K231).
|
||||
Positions J2 through J6 are the general purpose slots for the connection of the peripheral
|
||||
adapter and other interfaces to the computer. These five positions are identical, and Figure 2.2
|
||||
defines the type of connector, while the pin assignments are shown in Figure 2.3."

Two additional plug/socket connections are possible on the bus. These are made on the solder side of the controller board
|
||||
and are designated J2A and J7 A. These connectors are not considered to be user accessible , rather for factory use ,
|
||||
or for use by field engineers and system integrators. Normally, these two connectors are used for:
|
||||
??? J2A - The connection of the fixed disk interface board, or a custom design board.
|
||||
??? J7A - The connection of the 16-bit processor board (factory option and kit K230).
|
||||
|
||||
The processor and diagnostics module for Slots J7 and J7A have the following additional signals in addition to the ones present on Slots J2-J6.
|
||||
Note that the middle row of the connector (row "b") carries some signals too:
|
||||
|
||||
A2 - OPT 2
|
||||
Signals A19-A26 and C19-C26 are called e.g. A7 instead of BA7 in the processor module schematic (fig. 2.14, page 2.21 System Technical Manual Hardware)
|
||||
Signals A6-A9 and C6-D9 are called e.g. D4 instead of BD4 in the processor module schematic
|
||||
