You should remove jumper JP3. The FDC driver does not use interrupts. If it is set for "INT", it should not cause a problem, but if it is set for "NMI" it will fail. The silk screen on my versions of the Zeta are a bit misleading (made INT/NMI appear seem to be the reverse of what they were). Regardless, the best answer for now is to remove the jumper completely.

Let us know if that helps.

Thanks,

Wayne

One more Zeta sbc working!!!
The only problem: FD is still not working.
I have the Zeta SBC board Version 1.3.
I'm using a stabilized 5V 3A switching power supply, FDC_int is jumpered at JP3.
The CPU clock oscillator is 6MHz.
Exactly the same behavior as Brian Pitt described on the N8VEM Zeta homepage (at the end).
I try to format a 720 disk with FDTST, choose the necessary options but no LED on at FD.
'Reset drive' is shown in the terminal programm, then the menu appears again.
STAT tells me that there are 3 devices (A,B,C) but they all are R/O.
I'm afraid I do not exactly understand the solution Brian Pitt describes:

"Hi Wayne
Now got it working. Have taken out link J3 . Screen print on PCB is ambiguous.
Can now successfully format copy and read Floppy.Thanks for all your help.
Last question for now ( I am new to CP/M ) How do I amke a bootable floppy.
Thanks
Brian"

Someone here who can give me a hint?

Thanks Norbert
