This must have been a later version than the one I was given growing up. The one I had only had Apple support. There was no Y cable included, or necessary, because the ADB ports on the Apple keyboards were already chain-able. I just plugged my Alphasmart into the unused extra connector on the keyboard itself!
Yeah, the demo unit I was originally allowed to use was Apple only. At some point my parents were able to purchase the "Alphasmart Pro" for me which according to Wikipedia is their second model that added PS/2 support.
And you are right, I totally forgot about that extra ADB port on the apple keyboard!
