Amen!  Pull out that old MFM controller board and stick in a SCSI and
you're at WARP1.  Add it a smart I/O cache board with 10 megs of memory and
your at WARP8.  Want to get to WARP10?  Ask Michael Abrash to come in
and convert some of your critical code to "his best" assembly language!

Don't know how to do that stuff?  Buy a Sparc2!  

For $4000 I can dedicate a soupped-up PC
full time to sequence crunching for two years and "afford" to
throw it away when the technology is made "obsolete" by natural
marketplace evolution.  Can you afford to chuck your Sparc Station after
2 years?  :^)

         Lighten UP!  It's just a computer doing that to you.
