Schematic of the FDX
80 Column Board The source was bit unclear, so my
schematic may have some inaccuracies in it. I have made
a few minor changes based on "reverse engineering" of my
boards and added a few comments for my own benefit
(which may, or may not, be correct). |
Drawn by Dave Stevenson, using
KiCAD, from the original document supplied by
Peter Kretzschmar. |

Schematic of the SDX "FDC
05" Disk Controller (Includes the logic
equations for the PALs) Rev 2, 11/24. Drawing error
corrected and design verified as working. |
Drawn by Dave Stevenson, using
KiCAD, from original documentation supplied by Tony
Brewer. Tony has also checked the schematics for
accuracy and contributed a lot to its layout, so in the absence of any official circuit
diagram, this is as good as you are going to get! |

Schematic of the
Memotech "Speculator" (Includes the logic equations
for the PALs) |
Drawn by Dave Stevenson, using
KiCAD, based on reverse engineering of his original
design by Tony Brewer.
Again, Tony has also checked the schematic for accuracy
and contributed a lot to its layout. |
