1, Sorry for driving my Tank into this 'thread'. 2. Thank you VM for the hard info about DFU etal. 3. FYI I ported a 68030 embedded ASM system I inherited from MAC into Windows GUI asm+CPU emulator, added support for H/W simulation & had new ColdFire HW + C++ system built in parallel. Hence the H.S. comments. 4. Will try the Forums - last time I tried it was a shambles & I left, TKUVM - how do I scratch all my rubbish now? Mike
