Reimaged XF551 Disk Drive Controllers v2.0

XF551s

 

It’s been a long time coming.  I apologize.  This is the final version of the original reimaged XF551 boards.  I am considering doing a proto XF551 in a 1050 case, but I doubt I’ll produce it for sale.  I have all but used up the SIO connectors I could find.  I could use a DB9 or DB15 or sell the board without the SIO connectors.  Not really what I want to put my name on.   🙁

I have fixed the issue with format and write that cropped up on the reimaged version 1 original power supply board.  The modern power supply version was a simple fix and not always needed.  Some owners never had any problems.  The reimaged version 1 original power supply boards were a little harder to fix,  requiring a redesign of the board.

I am in the process of finalizing the mod board long promised.  Testing proceeds.
