Hi
I did some searches. First I found a company
that is listed as having DTL devices form one of those
master list of companies:
http://www.mathiselectronics.com/
The only thing is that they do not list them on their
web page.
A little nore in depth search ( remembering that I might
have actually posted information to this group in the past )
revealed:
http://lansdale.com/homeprod.htm
Of course, I was wrong, they were in Arizona and not Texas
( it was the desert that fooled me ). They have quite a
listing of DTL parts in the Motorola section. If anyone
does contact them for prices, could they let me know?
I see they have a minimum $1000 order.
