...I would have to have your bootcode files v1.57 so that I can make a file comparison with mine.
then do a flash test.
What exactly do you want to flash (=program)?

You cannot upgrade the CPU! The CPU has a 32 k memory aera (it's like an eprom) which you can program only one time! This is called OTP (one time programmable). Once it's programmed it can't be erased and/or re-programmed (overwritten). You'll either need a 'windowed' version of the H8/532 CPU (which is as rare as hen's teeth 8O ) or a 'blank' version of that CPU (never been programmed before) - seems to be also like unobtanium! 8O

If you're able to program eprom(s) by yourself - I can send you the SEQ. ROM v1.30 binary file... :wink:
