[Coco] Drive speed incompatibilities

[fsteeman at dds.nl]

Hello all, 

I was wondering if anyone could help me! 

I recently replaced my two really old floppy drives with a single unit 
combining a newer floppy drive 0 with a new diskette drive 1 I bought at 
vintagefunworld.com. This was meant to easily moving files back and forth 
between my PC and CoCo. It works fine with running programs downloaded from the 
internet on my CoCo. But I also had a plan to backup all my old floppies to 
diskettes and then pop these into the PC to convert them to virtual disks. 
However, I am not getting anywhere, because the new floppy drive cannot read my 
old floppies ! 

I was told this may have to do with differing drive speeds and I am pretty sure 
now that it is that. I have then tried to connect my old drive0 to the newer 
drives in all possible kinds of permutations, but I just cannot seem to get 
them to work together! 

Another solution would be a program called COLORTAC.BIN, which helps in 
determining and adjusting the drive speed. Could anyone pass me a copy of this 
or give some other suggestions on how to solve this problem? 

Thanks!
