Hello, thanks for this great forum!
I come here with a question still can't answer: Some days ago I was checking a pcb that uses the uPD72069 floppy drive controller. I searched thru the web and all datasheets for that floppy controller is the same pdf version, the one that identifies as "T-52-33-51".
It happen that the pin-out version for the 100 pin version does not correspond with the chip I have in my pcb. The 2 Xtall resonators, the Gnd's, the Vcc are on different pins. Why I'm posting this here? Because looking at the video of the Mavica I see it also has the IC pinout same as my pcb. But this does not match what the datasheet shows. Please look at the video, still on the section where the uPD72069 shows, and you will see the 16 Mhz resonator is connected to the pins #82 and #83 (like in my pcb). But the pdf says the resonator should go to #56 and #57. It is place for the second resonator but that also do not match the pin-out either.
So I'm trying to find and download this camera schematic to see if there is a identification for the uPD usage pins. But the schematics I found have little to say about the uPD, even it does not appears.
Is just me, or the uPD70069 pdf is totally wrong in all copies I have found so far?
Does someone has a schematic of other equipment where this floppy controller have been used...?
I need the correct pin-out for scope signals analysis as my pcb refuses to load the diskettes.
btw, I borrow a camera like this long long time ago, to take pictures of my sister weeding
