As some of you may know, I have a Falcon in a tower. (See http://tbird.atari.org )
I recently trashed a PC network card giving me a metal plate just the right sized holes to mount mini din for LAN port and for an HD-25 connector for the DSP.
One problem. Where can I get a HD-25 connector (male and female) to make an extension cable to attached from the board to back of the case??
