I am in the market for a WD1002-05 or WD1002-HDO controller. Are these software compatible to the WD1002-27x ( of which I have 2 ) ? Does anyone have a software and/or schematics manual for the -27x ? I do realize the -27x is RLL, the others are MFM, but then I have a choice of disks to use. Or could the -27x be jumpered for MFM compatibility ? Target : - Obtain a harddisk with 100 sectors (@ 256 bytes/sect) per cylinder. 4 heads with 25 256-byte-sectors-per-tracks should do the trick. I do no care about lost space on the disk. Jos
