I started out with a Duo 280 which had the 68LC40 no math co-processor was my memory. I also had the duo dock on my desk which had a large screen attached and 2 Nubus card slots. When I traveled it had an ethernet module that plugged into the expansion port. The duo was my favorite Apple laptop form factor.
