HDD and COM port on Profi

ZXNet echo conference «real.speccy»

From Aleksey Sidelnikov To All 18 August 1999

/Glad/ /to greet/ /you/, *All* !

People! Who can give _detailed_ _information_ on _addresses_ and
_programming_ of the _HDD_ controller and _COM-port_ on *Profi*.

_There are_ ready-made _circuits_ for both, all that remains is the decoders
to be completed. I don’t want to split RT-shki, maybe someone can tell me.

P.S. There is a diagram of the _XT-keybord_ controller from *Profi*, in text format.
Connects to any ZX.

Have a strong connection!

*Aleksey* *Sidelnikov*.

I have the source code of the Profak HDD driver somewhere, all the ports seem to be
described there. I can throw it, is it necessary?

Well, throw it here.


All the best.
