HP 2116 on ebay

[Jay West]

This is a classic HP currently on Ebay, a decent 2116C model. Item is 
290099957210

What is so special about it, besides the obvious? Seller updated the auction 
listing with a card list. It appears to have two of the (rare) 12920/21 mux 
sets (32 ports), something that is required for all versions of TSB. I'd be 
willing to trade a nice mux panel for them in exchange for one of the two 
mux sets ;)
