1. Timex FDD or ZEBRA VA.2 TOS.
panegustavo · 09 Oct 2015 13:28:26 -
Hello All,
I would like to consult the group, if any of you have the documentation of the T.O.S. low level functions
and parameters to be used in Z80 assembler.
These functions are part of the floppy disk operating system of Timex FDD or ZEBRA VA.2 TOS.
In particular, i would need to know the group of functions related to the files handling, example:
(OPEN FILE (000H), CLOSE FILE (001H), CHANNEL STATUS (013H), READ FILE (010H), WRITE FILE (00FH).
Unfortunately, during these years I lost that documentation.
Any help will be welcome.
Thanks in advance
Regards
Gustavo

Hi GustavoThere is a FDD300 service manual at http://wos.meulie.net/pub/sinclair/technical-docs/FDD3000_ServiceManual.pdf
Inside you can find its rom's source code and some programming references
At http://wos.meulie.net/pub/sinclair/technical-docs/ there is a bunch of docs.
