Riso RC // any other color drums work with RC?

[Guest]

Hello All:

I keep seeing conflicting compatibility being listed on ebay auctions/etc for color drums...

I am trying to find some that work with my RC5800 (i know its old, but it is still working great)...

I'm seeing drums listed as for GR machines inside RC cases and it's all a little confusing... as they seem to have the same pin/connector as my RC drums....

Any advice as to what to EXACTLY keep my eyes open for/etc.

Thanks.
