Re: ZIPGS

[andrew.webber4@virgin.net (Andrew Webber)]

I posted this recently and realised that the comments I made with
reference to Joachim Lange could be mis-interpreted and damage his
reputation. I wanted to clarify that Joachim Lange did a great job on
the card and is extremely helpful with all aspects of the work that
was carried out.
 
The issues I mention within the posting are not to do with the
modifications carried out by Joachim as the card works fine at 8MHZ
(which is how he recieved the card). It is only when I put in a 50MHZ
oscillator that i start to get crashes etc, these are modifications
that I have carried out myself.
 
Thanks
 
Andrew
