SWTBUGA - Augmented SWTBUG SWTBUGA adds the following enhancements to SWTBUG 1.0 - Similar to the "O"ptional port prefix for the L, P, and E commands, a digit prefix (0-7) can be used to specify any port for an MP-S board to use for the L, P, and E commands (e.g., "2L" to load from port 2). - Following a load command, the I/O port address used is saved at $A046 which will load into register X if a "G" command is used to enter the loaded program. This is useful for a two-stage loader. - The "D"isk boot command has been fixed by adding a delay for the motor to spin up and a check to see if the boot sector was read without errors. The boot operation is tried up to ten times. If a DC-x cont- roller is not detected, or boot from the DC-x fails, the a boot from a Percom controller is attempted if it's presence is detected at $C000. If that boot option is not present or fails, then control returns to SWTBUG. - The new "T"est memory command (SUMTEST) is followed by the low address and max address+1 of the memory range to be tested. The test runs until reset is pressed. SWTBUGA maintains all of the entry points of the original SWTBUG. Since SWTBUGA is larger than 1K, it must be located in an EPROM board on the bus and the CPU board modified to allow off-board access to $E000 through at least $E500 or so.
