copymem src,dest,count
fillmem dest,size,value
out port,byte
basic - (attempts to..) return to BASIC leaving mem mostly intact
new ramtop - as CLEAR ramtop, NEW; leaves mem intact above ramtop but any BASIC prog is lost.
set tstates value - change current tstate count in the frame
set intlen value - change the interrupt period for the current machine
keyb - simple list of keyboard ports
ay - lists the currently selected AY register and all AY register values
master "program name" 48|128 filename.tap (if zx7.exe is in SpecEmu's folder)
tk - lists current values of port $FC and $FF for TK-90x
hz - refresh rate of current machine
tapeinvert - invert tape polarity
stop <breakpoint conditions> - creates a conditional breakpoint which overrides all other conditional breakpoints until the debugger next opens
slowmo - creates a false interrupt delay when writing to display memory (see how some games draw the screen)
bw - sets black & white mode (or supply an attribute value parameter), use along with slowmo to see screen drawing at work
asm <opcode> - if pasmo.exe is in the SpecEmu folder, assembles an opcode at the address at the top of the disassembly window
ops - opcodes executed since last time the debugger opened

z80v1 - saves 48k .z80 snaps in v1 format
z80v3 - duh
