AD-9851 on a Type II DDS
Hendy reports that he found eBay item # 381248883052 It's a Type II DDS with an installed AD-9851. He ordered and received the module and it was indeed a 9851 (at least, that's the way the chip is marked) I don't think he's tested it yet, but the price is not bad - about US $12.
The vendor name is "smooth-dealer" ..... gives one pause, eh ? But I've risked more at an untried pizza joint :^))
