 I gather that some one has the Dave Gershwin board working with a 3174. 
  Was that
you.
  You also need 2.88 format for the 3174 floppies.
Any one modified any
 of the floppy emulators To work at this density. 
 Yes, that?s me but I have had issues with the emulator starting up reliably so
 that the 3174 boots.
  
  Actually, the format is 2.4MB (2x 1.2MB).  It?s a
5-1/4? format instead of a 3-
 1/2? format.
  
Sorry been working on my PC Server 500, I assume the data rate is double, so the existing
devices are not easily modified?
