- ADB and PS/2
- charset ROM is wrong
- asma2k keyboard doesn't work
- asma2k accesses memory below 0x8000; is there more ROM there?
- asma2k accesses memory below 0x8000; spellcheck ROM is probably
banked there
- asma2k reads from nonexistent internal register at 0x0001
(probably a bug, since the same code exists in both BIOSes)
