Hello and MFM question

Post by Hernan »

Hello Everybody. I am Hernán Acosta, from Tucumán, Argentina
I am very interested in this project, HxC Floppy Drive Emulator. I wanna help and I have questions.
How can I do a MFM encoder/decoder (data separator) to NRZ?. There are (or were) some chips like DP8459 but they aren't in market today.
I think I can do it with some PLL circuit but I need some help.
¿How can I implement it, for a floppy disk data rate?
Thanks
(excuse me my english, please)
