Now HTMLised for no very good reason on my site. Cheers, Cliff.

That looks good and the pinout of the port is useful too. If you don't mind
I'll put a link to your page on mine.

By the way. If there's anyone else with a PCW, CPC or NC page that I don't
already have a link to then I'd be happy to add it to my page if you want
to reply here or email me.

this is an Issue 9 spec

for interest :) we wrote all the software from an Issue 7 spec with
Mej's handwritten corrections to the video map to make it into an
Issue 8. The only changes I've spotted so far refer to external
hardware interfaces... and are not especially interesting.

I think Cliff may have edited the introduction slightly .. in 1985 we
would not have had to explain what "ANT" was.

I think I may still have a board somewhere in an attic to which
section 10 is relevant... others should ignore it completely!

Those people writing emulators may wish to ignore section 8.2. These
features were never used (intentionally anyway) by any Locomotive
software, and were never made public so I seriously doubt that any
third party software used this.

Experts on the CPC464 architecture will understand why they are there,
and will be interested to know that they were present for the ANT to
use (and that part of the gate array was identical between the two
machines). I believe that memory expansion boards (to which this is
relevant) will not honour these commands - so I would not recommend
anyone to write software to use these features now.

Historians may wish to keep a copy of this article :)

Better than that, I'll add it to the text of the document.
