Subject: BDOS Help Needed

     We have a vintage Imsai 8085 S-100 system with two 8" SS/SD drives
here that we are configuring as an RCPM system for out local clup.
(Mohwk Valley Microcomputer Club) All the software is finished and runs
well.  I purchased and installed the Optronics Technology timeout board
on the disk drives to reduce disk/head wear,since this board will be
operational 24 hours a day.
     Here's the problem:  The timeout board triggers on the "drive
select" line from the controller.  When it sees this signal, it turns
the 115VAC back on to the spindle motor.  Several seconds after the loss
of this signal, the board will power the spindle motor down.  This
system uses "Fischer-Freitas" CP/M 2.2.  I need to find someone who has
worked with this BDOS and can point me in the direction of how to patch
it to bring the drive select down after a disk read.  I'd do it myself,
but time is at a premium right now and I'd like to get this board on
line.
     Thanx much, in advance!
