[Coladam] disk drives

What about just replacing the drive mechanics if something goes bad (like 
the drive motor, broken belt, read/write head, etc.) with an old 5 1/4" 
DS/DD 360K Disk Drive and use it as a SS/DD 160K Drive. It would probably 
take a lot of research and buying different drives to see if you finally 
find one that has all the same sensor hook-ups since adding a sensor would 
be out of the question for almost all but a select few people. I could swear 
the drive I picked up for an old PC to do transfers between the ADAM and PC 
has all the same sensor hook-ups, but I will have to pull it in order to 

That socketed chip on the controller board behind the power switch is the 
drive BIOS and the only one that would have the program data that gets burnt 
to these chips for a drive conversion to 5 1/4" 320K, 360K or 3 1/2" 720K is 
Terry Fowler (unless someone pulled the chip from their drive and had it 
dumped). This software was written by Jim Marshall / MMSG for drive 
conversions that Ed Jenkins offered and Terry Fowler used the same 
conversion kit.

 John Lingrel / Orphanware was the first to perform drive conversions and 
had his own software written probably by Tom Clary or Glen Gabarik... but 
there were some issues as I recall that developed over time but I can't 
elaborate as I don't know for sure.

Think we have ourselves a mission on our hands... especially if the SD Drive 
isn't mass-produced.
