I have an RP11. In my copious free time I'll see what flavor it is.
It'll be at least a month though, I'm just leaving on a big vacation!
:-) - remind me then!

At least using google, there is practically not a single information/document on the RP11-E other than its existence in the past. Is the difference maybe just a different input voltage specification (110V vs. 220V)?

> The 1976 Peripherals Handbook lists the RP11-C.  It shows two variants of the controller: RP11-CE (115 V, 60 Hz) and RP11-CJ (230 V, 50 Hz).  It also shows two variants of the drive: RP03-AS (230 V, 60 Hz) and RP03-BS (230 V, 50 Hz), both of those are three phase.
