RDREG is a general purpose program to read and interpret the Massbus
registers in a device connected to an RH20. As such it is useful for
debugging hardware and software problems related to such devices.
RDREG can be assembled to run under both the TOPS-10 and TOPS-20 operating
systems based on a parameter in the universal file RDRREG. The program
itself is totally table driven based on tables in the universal file DEFS.
At present, universal files exist only for the DX20 (DX20.MAC). This file,
when assembled, creates DEFS.UNV that RDREG searches.
To build a program that reads and interpretes DX20 Massbus registers, you
must assemble RDRMAC.MAC, DX20.MAC, and RDREG.MAC in the following manner.
First, insure that the parameter "TOPS" in RDRMAC is correct for your type
of operating system, i.e., 20 for TOPS-20 or 10 for TOPS-10. Then assemble
RDRMAC.MAC to produce the universal file RDRMAC.UNV.
Second, assemble the device specific macro definitions file (in this case,
DX20.MAC). Note that the result from this assemble is DEFS.UNV; it does not
have the same name as the source file.
Finally, assemble RDREG.MAC. RDREG will search both RDRMAC.UNV and
DEFS.UNV. The result (RDREG.REL) should now be loaded and saved with the
name of the type of device it was assembled for, e.g., DX20.EXE for a
program that interprets DX20 Massbus registers.
The program must be run with WHEEL or OPERATOR capabilities enabled on
TOPS-20 and TRPSET privileges on TOPS-10. When the program is run, it asks
for the RH20 device code of the RH20 that controls the device. On a
multi-processor TOPS-10 system, RDREG will also ask for the CPU number to
which the DX20 is connected. You can find out what the answers to these
questions should be by asking your field service people. RDREG then reads
and interprets the Massbus registers for the specified device.
You should always run this program on a hard copy terminal so that the
output can be saved for future reference. In addition, the output should be
annotated with the date and time and the reason the program was run, i.e.,
describe the symptoms that caused you to run the program.
An example of the output produced by this program when run on a TOPS-20
system is as follows:
@ENABLE
$RUN DX20
RH20 device code: 560
