The ROM can then be fed into NDISASM, the disassembler included with NASM:

The `-o0x8000` argument is required to "org" the file at the proper starting address, but the `-s` arguments
are optional; they simply establish a few sync points within the ROM image that save a little cleanup effort, by

Next, the PCjs [TextOut](/modules/textout/) command, with the *--nasm* option, prepares the code for reassembly:

nasm -f bin 1988-01-28.asm -l 1988-01-28.lst -o 1988-01-28.rom
However, it does NOT produce a binary identical to the original ROM, in part because of instruction ambiguities (ie,
instructions that can be assembled multiple ways). It's possible the reassembled ROM may still work, but more research
