Backups are getting to be a pain with the low capacity floppy drive provided with the UNIX-r PC. I would like to know if someone has performed such a deed or technically knows whether the 1.44 high density drive 3.5 inch floppy drive can be simply replaced. I do know the data rate needed by the high density drive is MFM 500 K-bits/sec where the current rate in the drive is 250 K-bits/sec. I took a look at the reference manual and the clock provided to the WD2797 floppy disk controller is 1 MHZ which is coming from the DMA address chip. If anybody knows please email, call, or post to this newgroup. Thanks. -- ^^^^^^^^^^^^^^^^^^^^^^^^^^ Lou I.
