To the best of my information: CRC/Disto made 3 versions of floppy disk 
controllers.  The Super Controller, the No-Halt Super Controller 2 of 
which I have one sample of each and the Mini-Controller, of which I have 
not seen yet.

I also have the RAM Disk/memory expansion pack, normally released with 
512k of memory, however mine was upgraded by piggy-backing half of the 
memory chips for 768k.  It is clear that another 256k could be 
piggy-backed on the other memory chips for a whopping 1 meg of memory 
usable as a RAM disk.  All three of these have the Mini-Expansion-Buss.  
I also have the SASI adapter and the EPROM programmer that plug into the 
MEB as well as the 1 meg CoCo 3 upgrade.
