Step one: Throw away the IBM RLL controller. There's kludges like the
"Wedge" that'll let you do it, but you don't want that.

Step two: Buy a C Ltd. SCSI controller and an Adaptec 4070 SCSI-to-RLL
adaptor. Total cost: around $300. 

Step three: put your drives in some sort of case, figure out what kind
of power & cables they need, hook everything up, and run'er. Cost
depends on what you have in your electronics junk box. e.g. if you
have a surplus IBM power supply, or a couple of old computer cases
with spaces for half-height drives, or whatever. If you buy a case,
with a power supply, it'll probably run you about $80.

I've gotten around 300k/second diskperf out of a similiar setup (using
a Miniscribe 40ms drive -- dunno what your Seagrates will do).  If you
want real scream, get a high-performance SCSI controller and a high
performance SCSI disk drive.  But if you can't afford that, well, it's
better than nothing....
