I bought this modem... Merry Christmas to me! I too thought it was steep, but 1984 Me demanded we finally have one. Does anyone have the specs on this thing? Specifically, the DC power requirement? It came with everything except the box and power adapter. I'm guessing by the barrel jack for power, that there's a transformer brick at the other end of that cable, but the manual does not give a voltage. Any help would be greatly appreciated! (And yes, I'm now trolling ebay for a Bell/Western Electric model 2500 to go with it!)

Is the Chicago Faire always in October? Is there a mailing list to join, for when announcements are made for 2018's?
