The easiest way to distinguish between 68020+ and the others is:
MOVEM.L A7,-(A7)
CMPA.L (A7),A7
ADDQ.L #4,A7 ;Reset A7 and leave condition codes
unaltered
BEQ LOW ;Not 68020+
Interesting... this seems to be the opposite of what

I thought it safer
to try a real 68020+ instruction, such as BFTST, to check the type of
machine. This is much more likely to be a proper test for an
emulator.
Problem with this is the need to go through TRAPV - something I
have long

I need to make some amendments to my QWord program to get the code working
on Q-emulator.
The problem is because I use both MOVE.W (a1)+,(a3)+ and MOVE.L
(a1)+,(a3)+ on both odd and even addresses.
Now this crashes on a 68008 chip but I am not concerned as QWord needs a
Super Gold Card ideally
Is there an easy way under QDOS to check which chip is in use - if it is a
68000 or 68008 I would use 2 (or 4) MOVE.B commands instead? SMSQ does
implement the processor in the system variables, but it is not present on
QDOS alas.
Here is what smsqe does:
