Hi Andy. I see. Do you think there could be an 'drop in' solution for an 1284 in a jumper box? http://parts.digikey.com/1/parts/290826-jumper-box-db25-male-db25- female-ab973-r.html Will it fit into the holes of the borad that is in there already?
In such a box it would be a nice 'of the shelf' micro for rough environment. Femal side has the ports, male connects to terminal and programmer.
