To create a pre-loaded image from the BASIC paper tapes you first need
to adjust the primary loader used for the BASIC version, and assemble
it with the Intel 8080 cross-assembler or DRI's asm. Then load the
BASIC tape with:

	./altairsim -s -m0 -x ldr2sio.hex < "8K BASIC Ver 3-2.tap"

Now switch the machine on and toggle the Run key, wait until the memory
size prompt appears, then abort the simulation with CNTL-\. The CPU
registers and memory contents will be written into file core.z80 caused
by the s[ave] option.

To convert the core image to a pre-loaded BASIC image in Intel hex format
use:

	bin2hex -i 52 -l 8192 -o 0 core.z80 basic8k32.hex

Input offset 52 is because core.z80 includes the contents of the CPU
registers, but we want the memory image only.
