I agree with you. Btw. Are there some informatiosn about how to add
new hardware to Hatari (e.g. SCC for the TT)?

i think, you are right if you expect, someone will ask a year later,
why the SCC emulation did nothing. But i believe, a year later also
someone will ask, why he get a bus error if he access the SCC via
XBIOS and get a bus error. I think, every solution is only a
compromise. and no solution is perfect but only add SCC support.

But ther eis a additional argument. MiNT wont run if the access to the
SCC via xbios of TOS 3.06 generates a bus error.
