Use BIOS (easiest):

http://www.cpctech.org.uk/docs/manual/s968se19.pdf

Use KL FIND COMMAND (&BCD4) to get the BIOS function, then use RST 3 to execute it.

Code Select Expand


ld hl,format_command call kl_find_command ret nc ld (format_cmd_data),hl ld a,c ld (format_cmd_data+2),a

Code Select Expand


rst 3 defw format_cmd_data


Direct to FDC (hardest):

http://www.cpcwiki.eu/index.php/765_FDC

[robcfg]

The 765 FDC article lists FDC9216 as the data separator.


Wasn't it the SED9420?

I think there were more than 1 data separator used. The FDC9216 may have been a mistake. Please check the scanned pcbs.
