What are the differences between the DEC RP11-C and RP11-E controllers?

[Mike Ross]

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)?
