Best Atari 810 Tech Tip:  Atari 810 problems fall into a few different basic reasons / problems.  A dead (no LED or LED's works but no mechanical movement) 810 is usually a bad rear Atari 810 Power board.  It could also be a combo of both a bad rear power board and sideboard problems.  A mechanically working 810 disk driver that have Read (boot errors) or Write (can not format a SSSD 5 1/4 Floppy disk, which is one of the true tests of the health of any Atari 810 or Atari 1050 Disk drive) problems is usually a 810 5 1/4 Disk Drive mech. problem.  But could also be a combination of both a bad 810 disk drive mech. and bad 810 sideboard problems.  Early made Atari 810 Disk drives had two known major problems.  On early production runs of the 810 sideboards, they did not have the 810 Data separator board plug in upgrade daughter board (the WD 1771 disk controller chip plugged directly into the side board).  The second known problem was the single rear 810 power board.   Both were known to cause all kinds of problems with early Atari 810 disk drives and the only way to fix them was to add the 810 Data separator board and install the 810 improved rear power board.  The Atari 810 disk drives without the Data separator board had all kinds of Read and Write 810 Head problems.  The single 810 rear power boards had all kinds of speed problems that seem to change all of the time without making any kind of speed adjustments on the single rear 810 power board.  Both known 810 problems we latter fixed in the Atari 810 production run with a new plug in 810 Data Separator board (which cured most of the 810 Read and Write electronic data problems).  The second Atari 810 Major problem was cured with what is known within Atari Engineering as the Atari 810 Grass Valley board set (where in California it was designed).  This Atari Engineering Grass Valley 810 new board set cured all of the Atari 810 speed problems.  It consisted of a new redesigned / improved replacement 810 rear power board and a second daughter board (sat over the 810 Disk Drive mech. and was connected to the rear 810 board with a 10 pin wire harness and to the 810 Head wire harness).  The second Grass Valley 810 daughter board helped to separate and boost the Atari 810 disk drive Head signals.
