I am trying to restore a CBM D9090 external hard drive. The controller
cards seem OK, but I get a "? bad disk" error when attempting to
initialize (using a B128). If no Tandon 603s is available, does anyone
have experience and success replacing the original stock Tandon 603s drive
with another drive? I have read differing opinions about what drives are
compatible with the D9090. I tried a working ST 412, but I think that this
is too new. Did not work. The drive I believe has to be 7.5 to 10 MB with
even heads.
