SC 708 auto set to serai insert sc 725

[Nicolae Muntean]

Hello I have a configuration sc 708 sbc and cs 715 cf card, which on serial bit-bang at 9600 on sc 708 works ok. If I insert an SC725 into the system, the test LED works ok, ON - OFF - ON, serial A from the SC725 works with tera term and displays the monitor at 115200, only that at the command "CPM" it freezes as if there is no CF card. Need a another CF image?

I mention that I did not insert Z80CTC in SC 725, configuring Z80 zio jumpers to receive 7.3 mhz on ports A and B from SC708, proof that port A works thank you

Ok! You have a book, you have a share! says a Romanian proverb.
BIOS B was needed!!!!!
I created CF card with CP/M BIOS B
THANK YOU
