But just tell me where 32 Bit instructions can be usefull ?
In fact, I can't think of any part inside a BASIC. But the
higher clockrates are a nice thing - and maybe the z180 for
3.0 style bankswitching.

BTW: LDOS - I have a Modell III with external HD - hasn't
there been an LDOS to boot from ? (I'm not the deep TRS guy).
