Hello:

So I recently picked up a Riso RC 5800 machine... I know it's old and parts are hard to come by, etc etc... I'm well aware of all the possible problems... but it was free... so it's worth the risk/work/etc.

BUT...
I was wondering if ANY other color drums besides the RC drums work on it?
On ebay there are drums advertised for the GR series (I know people mis-list on ebay constantly) that are identical to the RC drums I have (they included a close up pic of the connector pins/etc)...
I'm fine with snipping/soldering some pins if needed/etc...

ANY advice would be amazing... as I have tried to find any on this... but since this machine is so old it kinda pre-dates heavy internet information...

THANKS!
