Finally got an eprom adapter for my TL866 and burnt the Diagrom to a 512k 27c400 for the A600 I had lying around and bingo ..said Paula was bad
Even learned how to swapbyte lol because the program with the TL866a will not do this.
So found a willem prog that will do it, then loaded and saved the output file after swapping and it works perfick
on the TL866
Great work Chucky ..donation incoming
