AppleShare 4.2.1 and ARA Multiport Server

I recently obtained the AppleShare 4.2.1 upgrade, which includes Apple Remote Access (ARA) Multiport Server 2.1. However, I cannot find the ARA Client software nor the four port serial card, both of which are mentioned in the ARA Multiport Server manual included with the upgrade. Where are those items?
The version of ARA Multiport server that is included with AppleShare 4.2.1 is a special version that does not contain the card or any client software. Those items need to be purchased separately.
