 Well, Even though I knew that the System 6.0 was not supposed to work
with my Dove 1meg 512e, I went ahead and tried it anyway...

 It seems to work fine, although as I expected, my Dollars & Sense
4.1b does not work any more. That's OK, I just have not had my father
send the update up to me. As I have heard, Excel does not work
either...

 If the problem is the Sound Manager itself, then there is nothing I
can do about the missing memory, however, my Sound CDEV seems to be
working just fine as it is. I was under the impression that it was
only the Sound CDEV that used the extra bytes, but I guess not...

 On a side note, I reformatted my HD20SC under System 4.3 (the last
release) with the second release of the SCSI accelerator at a 2:1
interleave factor. The read time (DiskTimer ][) was improved from 158
down to 96, but I suppose that since the Accelerator does not patch
the write code in the driver, the write time skyrocketed to 388 for
the usual 100 24Kb writes. Oh well... According to the docs it was not
even supposed to work with the hardware in the HD20SC...

 And, of course, it bombs out at boot time when running system 6.0
with the accelerator...
