displays and prints eight words of hexadecimal characters per line until
the end key is depressed.
The 3210 Model 2 Adapter optional feature allows a 3210 Model 2
Console Printer-Keyboard to be connected to the system to function as a
remote alternate or additional console (either a 3210 Model 1 or a 3215
Modell can be the primary console). The 3210 Model 2 can be located up
to 75 feet from the
cpu.
This remote console cannot be used for
alter/display operations.
Store status is another function that can be performed using the
console typewriter keyboard in alter/display mode. The operator can
cause certain status information to be placed in processor storage by
entering the console typewriter mnemonic ST. The contents of the
following are placed in processor storage during a store status operation:
cpu
timer - locations 216-223
Clock comparator - locations 224-231
Current PSW - locations 256-263
Floating-point registers - locations 352-383
General registers - locations 384-447
Control registers - locations 448-511
The operator should perform the store status function to perserve
system status after an error causes a system halt and prior to resetting
the system to load a stand-alone sto~age dump program. Otherwise the
contents of these fields and registers at the time the halt occurred are
lost during the reset that is performed to IPL the dump program. The
stand-alone dump programs provided will
be
modified to obtain system
status information from the locations indicated.
