I can't help directly with the LocoLink software but you might want to take a
look at http://www.fvempel.nl/ which is a sort of PCW enthusiasts' site. They
might be able to help you. There are other sites linked from there. You could
try comp.sys.amstrad.8bit too.
Other than that, you've either got to try and get the DOS half of the LocoLink
software, some kind of serial interface or rig up something yourself. The Z80
bus is pretty simple to design for but I'm assuming you're not into that kind
of thing :-)
The only easy (relatively-speaking) solution I can think of that could perhaps
be cobbled together without any "serious" electronics would be some kind of
very slow low-level bit-banging program that did something like flashing a
blob on the screen to send bits to a photodiode connected via a simple
comparator circuit to the PC serial port. I don't know whether the version of
CP/M that came with the PCW included a copy of 'asm' to assemble the driver
program, though, and I don't have any of my CP/M-80 programmers' manuals any
I wonder if the proprietary printer port can be controlled directly from the
Z80 CPU...? That would be a good way to get data across.
Hm, I shall be mulling this over in bed tonight, probably writing the 8080
code to do it in my head :o)
