Hi Facias, I suspect you may find it easier to get in touch with Jeff by phone than by eMail. 302 and 312 do not contain the same ICE modules. 302 had a discrete power supply. I believe that the newer 312 uses a 3rd generation ICE module with integrated power supply. . . . and having said that, it has more authority than older 302. It is worth remembering though that JRDG uses ICE modules as basic low level building blocks, and only 102, and 201 should be deemed relatively minimalistic designs. Particular Continuum 500, 312 and 301 devices all have complex circuitry designed/implemented to support the ICE modules. I believe that Continuum 500 uses integrated power supplies which are fed 385V DC current by the PFC 1500W front end rectifier. G.
