schematics for floppy disk interfaces

[nikosdoykas]

so Jungsis Corner Community(Jungsi member )has 2 QL disk controlers i ask form him hi res pictures of them.... enjoy

so any CUMANA schematics

actully in greek language schematics call =σχηματικα ....(σχημα= circle , square ext)

Jungsis Corner Community(Jungsi member ) olso read the rom file of the x disk floppy controller

..... he sent me hires pics of the top of the board so i re draw the schematic of this ....

I AMNOT SURE ABOUT IT... IF ANY ONE WANT TO CHECK ... BECAUSE TOP BOARD HAVE HIDDEN TRACKS UNDER IC BASES....AND TELL ME WHAT CHANGES HAD BE DONE ....

BUSTED

so i take trump card schematic and... pisc of 0 kb trump disk card and i draw the schematic of this... i see that one of the 74ls175 that connect on d4-5-6-7 controls only the ds 2-3 (drives 3-4) so can removed to control only 2 drives?

the remain empty pins 74ls04 in pics has 0 ohm resistors.....

Hi, and HAPPY NEW YEAR!

Just for information there is PCB diagram ( both sides ) and schematics for the OPD disk interface from Computer 1 on the RWAP website. It's about as simple as they get and might give basic understanding of how it's all arranged.

That's smart. Is the data for the EPROM available somewhere? Perhaps I will go FDD on my OPD. Rich (if you see this), is that the type of disk interface that you said you had for the OPD but doesn't work?
