Re: A83: Re: 83 and 83+ ASM




TI completely changed the way that the ROM is structured in the 83+
(obviously).  ROM calls are accessed through a RST instruction, though it's
clever, and still only takes up 3 bytes.  This is quite different than using
a table, as on the 83/86.  Recompiling (or reassembling) requires having the
source code and using a different set of equates and possibly macros
(depending on how powerful the assembler is that everyone uses for ION).
