[Coco] DOS Adapter

[coco at yourdvd.net]

The ''neatness'' of your device is why I wanted one - I've never been
one for piggybacking a chip and cutting traces - instead I would socket
all devices and make little sat boards to go into them to avoid cutting
traces , etc. That way anything I modified could be put back together
exactly as it was before my modification, in case it eventually ended
up in the hands of someone else and they were a ''purist'' :-)
(of course I know trace cutting is isn't required for adapting a 24 pin
socket to a 28 pin device). The reason I haven't modified my 3124
multi-pak yet is because I want to socket the chips and avoid that one
trace cut, but I've got to dig out my vacuum desoldering station - it's
so much easier than the snip the pins remove them and place a socket
method.
Also, $20, I think, is reasonable for your device (having PCB's made
isn't cheap, though it's getting better).
Yep, your lil' DOS adapter is ''cute''
