Hi, I am Paolo from Italy and I have written the CONIN and CONOUT
routines for my Z80 hardware.
Now I start to develop Floppy disk routines (for uPD765 by NEC), and
then I need to make a complete BIOS for CP/M 2 (I have planned to switch
to CP/M 3 in future)
I would need *step-by-step* help to do this, I have poor experience with
assemblers.
Where I can put my routines? How i can assemble all together?
Please explain me as if I totally were stupid, please :-)
Next step: I will try to make my disk controller compatible with PC 720K
floppy disks (or 360K 5''1/4 if necessary). How I can make a boot floppy
for CP/M starting from PC?
Thanks in advance, above all for the patience. :-)
Best regards.
p.s.: please remove "ledita" and "dalnaso" from email for direct reply.
