 I know of about a dozen complete MARFS... and then there are 
another 4 or 5 around that are missing boards.... only a few of 
these are functional .... Don quickly scrapped the 248 MARF and 
replaced with the software MARF in the 300 series called the 364 
as the hardware version was buggy and pretty much everyone 
has had or needs service.. VERY cool module but not the most 
reliable controller.

chances are you'd get the "funky Xmas light effect" :)
might not work but looks nice.

that sucks as those Sliders are not easy to locate these days 
although some retailers will sell them  ($25+ each!!!!!)

I have taken them apart and cleaned them for Arps in the past as 
well as a couple of Buchla projects... this takes time and you 
have to be careful not to crack the plastic but it is worth an 
afternoon I think. 

 getting the front panel back on the 248, lining up all the LEDs 
and switches could  take another afternoon.. thats one of the 
most frustrating things I have ever done!

sweet system!!  I am sure it will clean up good!

have fun
