@ -16,6 +16,9 @@ TK85 seems to be the same as TK80, except is has a larger ROM. No
schematics etc are available. Thanks to 'Nama' who dumped the rom.
It has 25 keys, so a few aren't defined yet.
ND-80Z : http://www.alles.or.jp/~thisida/nd80z3syokai.html (newer version)
Like the TK85, it has a 2KB rom. Thanks again to 'Nama' who dumped it.
When booted, the system begins at 0000 which is ROM. You need to change the
address to 8000 before entering a program. Here is a test to paste in:
8000-11^22^33^44^55^66^77^88^99^8000-
