Well, it's difficult to start, but perhaps all of you would like to read this, 
it is something very strange to me:
I recently posted a premature version of my program DISASS for the 92 as it had 
always worked well on my Atari Mega ST, that is I wrote the roundabouts and 
posted it without really having checked it on my 92+. When I got the idea of 
doing that I really was astonished about it's lots of mistakes.So I 
retransferred the routines used on the 92+ to the atari, assembled them there 
and let the kernel run using my debugger: theresult was that I found 2 slight 
errors and one mistake, but not the ones made on the TI, for example the first 
order in my test-file is cmpa.l  a4,a3; result on the atari: cmpa.l a4,a3 0; on 
the TI: cmpa.l a4,xx with xx not being really comprehensive text, other orders 
are especially the immediate ones like ori, andi, etc which aren't written 
properly: ori.b  #$22,d3 is correctly disassembled on the ST, on the TI ori is 
suppressed and a lot moremistakes on the TI not encountered on the ST.
If someone of you is interested in tryind to find out about that I would send 
him the source privately, so that he could work on it. 
At the moment I myself am not able to do further tests as I had to send in my 
TI-92plus because of a broken link port (which clearly occured in sending varios 
changes to the disassembler routine for testing them), I hope to get it back 
within a week or so.
