The "ideal" drive is the micropolis 1335 - formats to 70 meg.
I say "ideal" because that is the drive that Tandy puts in for their 70 meg
units.   Maximum you can put on is 70 meg.  The system can NOT handle any
drive larger than 1024 cyl by 8 heads.

If you have a Tandy system now, just put the same jumpers in.  They send a
signal out the cable to turn on a relay to power up the secondary.

I don't even have that.  I am running non-RS Rodime 203E's.  Both external.
If you have an internal 15 and and external, you can move both up to 70's and
run a maximum of two drives.  If you have externals only, that controller can
handle up to 4 drives.

That about covers it for normal stuff.   The interface units for the R/S
version of the Bernouli boxex is basically SCSI.  Snapp in Cincinnatti (sp?)
has been putting up to 8  scsi drives in the 250 meg up range from what I
hear.
