		/*
		** We now need to insert a short boot section into
		** the memory at the end of Sram2. This is normally (de)composed
		** of the last eight bytes of the download code. The
		** download has been assembled/compiled to expect to be
		** loaded from 0x7FFF downwards. We have loaded it
		** at some other address. The startup code goes into the small
		** ram window at Sram2, in the last 8 bytes, which are really
		** at addresses 0x7FF8-0x7FFF.
		**
		** If the loadbase is, say, 0x7C00, then we need to branch to
		** address 0x7BFE to run the host.bin startup code. We assemble
		** this jump manually.
		**
		** The two byte sequence 60 08 is loaded into memory at address
		** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0,
		** which adds '0' to the .O register, complements .O, and then shifts
		** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will
		** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new
		** location. Now, the branch starts from the value of .PC (or .IP or
		** whatever the bloody register is called on this chip), and the .PC
		** will be pointing to the location AFTER the branch, in this case
		** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8.
		**
		** A long branch is coded at 0x7FF8. This consists of loading a four
		** byte offset into .O using nfix (as above) and pfix operators. The
		** pfix operates in exactly the same way as the nfix operator, but
		** without the complement operation. The offset, of course, must be
		** relative to the address of the byte AFTER the branch instruction,
		** which will be (urm) 0x7FFC, so, our final destination of the branch
		** (loadbase-2), has to be reached from here. Imagine that the loadbase
		** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which
		** is the first byte of the initial two byte short local branch of the
		** download code).
		**
		** To code a jump from 0x7FFC (which is where the branch will start
		** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)=
		** 0x7BFE.
		** This will be coded as four bytes:
		** 60 2C 20 02
		** being nfix .O+0
		**	   pfix .O+C
		**	   pfix .O+0
		**	   jump .O+2
		**
		** The nfix operator is used, so that the startup code will be
		** compatible with the whole Tp family. (lies, damn lies, it'll never
		** work in a month of Sundays).
		**
		** The nfix nyble is the 1s complement of the nyble value you
		** want to load - in this case we wanted 'F' so we nfix loaded '0'.
