I'm thinking that I would like to put together a
very small
Z80-based SBC just for this interpreter. Do you know if this
code is ROMable?
I'm reasonably sure it isn't ROMable. The good news is that the
user entered program is stored immediately above the end of the
listing at 1800H. Unfortunately, the input buffer appears to be
stored somewhere early within the address space of the listing
(1049H, I think), and although I'm still disassembling the code,
I half suspect that there is some self-modifying code in there.
At first, I even thought there was some self-modifying code in
the intermediate language, but I think I was misinterpreting
what was going on. In any case, there are definitely several
writes within the 1000H - 17FFH space of the code, but hopefully
I'll know soon how extensively one would have to modify this to
make it ROMable.
