Fixed RTI on older PDP-11s (ie, 11/20); the old RTI behaves like the new RTT, which did not exist on older machines

Memory can now be explicitly "zeroed" with any byte pattern (but the default is still zero); note that memory blocks are still always zero-initialized when first created

Fixed zeroMemory() to properly zero any block(s) that originally underlaid the IOPAGE block(s), rather than trying to zero the IOPAGE block itself (which would be a bad idea)

Added a variety of checks and automatic repairs to DiskDump, aimed primarily at issues I've come across with pre-DOS 2.0 diskettes (eg, diskettes without BPBs, like 160Kb diskettes from DOS 1.0 and 320Kb diskettes from DOS 1.1)

It is now possible to re-attach or re-load the current paper tape; re-attaching means repositioning it at the beginning, and re-loading means loading it into RAM again. Note that whenever you reload a tape, it's HIGHLY recommended that you reset the machine first, too.

Fixed stepCPU() so that, if a Debugger is present, it always calls checkInstruction() on at least the first instruction of a run, so that Debugger features like skipping over an initial HALT opcode works properly

Added getTrapStatus() so that the Debugger can display trap information whenever a trap has just occurred, updated FileDump to store 'load' and 'exec' properties in MACRO-11 listing dumps (so that the individual machine files don't have to specify hard-coded 'load' and 'exec' values themselves), and added a new SerialPort parameter (upperCase) that can be used to force all received data to upper-case

Supoprt for tape images in the Absolute Loader format has been moved to the RAM component, so that those images can be preloaded into RAM in the same way that raw bootstrap images can; the RAM component now provides Absolute Loader image parsing as a service to other components that need it (specifically, the PC11 tape reader)
