Hi folks,
I just finished the dual IDE board and installed CPM3 thanks to the wonderful guide provided by Yoda and David Fry, I did not encounter a single problem !
below a picture of the system running CPM3 (non banked as I still have an old Z80 board). I applied decals on the front and back panel to get good looking legends. I realize the available memory is quite limited (I think TPA is around 30-40K) so that limits quite a bit. Next step : get the real thing and build a NV8EM Z80 board !
cheers
Philippe
