Hi there,

If you have CT60 for Falcon, then you've probably noticed 
that basically no 030 debugger/monitor software doesn't work. 
Sure there is this internal debugging info about d-, a- and 
other registers, but this just isn't enough...

Tried everything from Devpac to Turbo Assembler, 
Pure Debugger etc... The result was always the same, 
it didn't work on CT60... Well, actually one did work, MonST 2, 
but the problem with this debugger was, that it only supported 
68000, 010 and 020 instruction sets. The other downside was, 
that it didn't support TT-RAM...

Also tried looking from the forums, what should be done to make
them work. Only found some messages, that somebody has managed
to fix Pure Debugger to run on Milan 060 or such, but 
unfortunately no info on how that was made possible...

Based on the following document 
(http://e-www.motorola.com/files/32bit/doc/ref_manual/MC68060UM.pdf) 
found out, that the 68060 processor doesn't support certain 
registers or instructions. In MonTT v.3.10 case it was:

Unsupported registers: psr, mmusr, isp, msp, caar

Unsupported instructions: ptest, pmove

With this patch file these unsupported registers and instructions 
are removed (hopefully) and you will be able to use MonTT v.3.10 
even on your 060 machine. Haven't tested though, if 030 version
still works...

To run this patch you should place the MON_P.PRG in the same 
directory with 030 version of Mon v.3.10. Run the program, and the 
MON.PRG will be the 060 patched version and MON.BAK will be the 
original 030 version...

Word of warning... Although a back-up file is being created 
before the file is patched, it doesn't hurt to make a back-up 
before running this patch, just to be sure...

Another word of warning... This is only a patch for 030 version 
of MonTT v.3.10 (and that version only!), which means that it 
doesn't support 060 registers or instructions, but in most cases 
it can run them if it can figure out what is the length of the 
instructions in words.

Do NOT expect a fully operational 060 debugger that works like 
030 debugger. In fact I've found out, that in some cases the 
program doesn't stop (!) on breakpoints and single stepping the 
trap can produce some unexpected results. Single stepping also 
causes some illegal instructions even if there are no obvious 
reasons for those. This is due to incomplete support of 060 
processor. For a better support of 060 processor, illegal 
and trace vector handlers, among others, should be reprogrammed...

Do expect though to be able to search'n'browse opcodes/hex 
(up till 040) and modify hex/asc and locate those unsupported 
registers and instructions, especially in the applications. 
With games and demos the chances of locating unsupported 
registers and instructions while running the program are 
from slim to none...

Anyway here is the patch file, version 0.12, that makes 
MonTT v.3.10 to run on CT60 Falcon accelerator, maybe on 
Hades and Milan 060 as well? This haven't been tested though...

Regards,
hakim
