[Color Computer][Coco] Tandy Hard Disk Controller

[George's Coco Address]

 Somewhere, I have a schematic of this interface. I looked for it yesterday 
and couldn't find it in my "hobby room"
 I may have it in storage (out back), or somewhere in the house I haven't 
looked, yet.

 Quite a few years ago, I called RS in Austin and talked to someone in a 
department(it's been a few years, OKAY?). He sent a fax of the diagram and 
there it was.

 I decided this SASI interface would not do for a Small Computer System 
Interface(SCSI drive) and never wired one up. I purchased the Kenton and 
haven't looked back.

 Now I have two of the Kentons.
 A SCSI system is supposed to allow more than one computer on a single 
drive. I've been tempted to try this. I just never took the time to test the 
OS-9 system to see if it would actually do this. The docs in OS-9 claim to 
do a sharing thing when accessing/writing the same file/record from more 
than one user.
 Untested.

  Has anyone ever tested more than one coco on a SCSI drive at the same 
time?

George
