[Coco] Disto SC needed

[Roger Taylor]

Well folks, I don't know what happened but my Disto Super Controller 
I which hasn't been able to write suddenly started causing read 
errors a while ago.

Doing a 'DIR' on any floppy either causes the CoCo to crash or the 
screen will clear, the video will glitch real quick, then you get the 
cursor.  I've tried 3 cables, recleaned the contacts (which were 
already clean), tried 3 CoCo's and 2 different drives with the same 
results.  I even reseated the chips.

Please tell me this is just a capacitor or something I can 
replace.  :)  Jeez.  I was 1 minute from burning an EPROM and was 
overly anxious to make some progress.

I don't understand what causes CoCo floppy controllers to suddenly 
break like this but over the years I've had many controllers do about 
the same thing, crash the CoCo when trying to read a disk.  In the 
pile they went.

If this sounds like a common WD1773 problem, where can I find one?

At any rate, I desparately need a Super Controller with the MEB 
connector so I can use my MPROM attachment.
