HP 82087A/B charger connectors

[ftjames]

I have both an 82087A and an 82087B charger (for the Spice series). The connector on my 82087A isn't the same as the one on the 82087B. The photos I've seen indicate that they both should have a small slide-in connector but my 82087A has a two pin push in connector. Both are labelled 1.8 va max, 10 V, AC. Does anyone know what calculator my version of the 82087A is supposed to work with? (Photos attached)
