I am probably the original source of that manual, and actually the manual is quite good .... except for the schematic. That probably reflects how the schematic in the manual actually was. I have two other files that contain the schematics for the 64FDC in a better quality format. One is a 24MB multi-page TIFF file (not too many readers can read multi-page TIFF files), the other is an adobe acrobat pdf file produced from the TIFF file which is a 6-page pdf file and it's only 720k in size. The 24MB TIFF file was scanned from an original at 600 dpi, and the pdf file, not withstanding that it's only 5% as large, seems to have retained the quality of the tif file.

It seems that the Harte Technology copy is all that's out there. The schematic is real poor quality Anyone have one they have scanned ???? Thanks, Jerry Jerry Wright g-wright at att.net
