Sharp MZ

Thank you both of you! for the infos.

I think this is a a long term project.
I will inform you af any proggress....

Hi! Tingo Thank you for a quick response my friend. You are asolutely right about ALL you thioughts, Let me 'walk through' one by one to express my opinion on your thoughts: - mechanical - does the card physically fit into the connector on the machine? No I think the card does not fit into MZ80B exp...

Still didn't managed to find an FDD interface card for my 80B. Do you think that an Sharp MZ1E05 will be in any way compatible with MZ80B-FI Sharp MZ80b-FI ? I know that MZ80b-FI card has no eprom and uses in-built IPL routines but do you think the rest of hardware will be compatible? Alex ;)

Hi S_U_C! Sorry for the off-topic but I would like your opinion on this: Do you think that an SHARP MZ1E05 FDD card works on MZ80B with signal rewiring? I know that 80B has its own FDD controller code on board intead if the MZ1E05 on board eprom but as it uses the same chip do you think is will be p...

Hlide, what you said is true my friend. I think there is a different approach involving 80B as I the fw already includes FDD support. (there is no eprom on MZ80b floppy card) I own a MZ80B BUT with no FDD controller and I really like to run CP/M on it! I had no luck finding an FDD card so far . ;)

Ηi to all out there!

Do you know if there is a MZ80B future support of the unicard.
I am searching for a floppy interface for my SHARP MZ80B!

thank you for your time

Alex

I also use one similar to this on my MZ80K and is working fine....

Thank you tingo for your reply. YES! that's exactly what I am trying to do. MZ80b-FI cards are really rare I think and is the only way I can read/load CP/M on this machine -I think. :) (With the help of some photos (found from the net) parts placement would be helpful and makes double sided autorout...

hi! It recently came to my possession a Sharp MZ-80b with MZ-FIO2 & a Custom printer like card. Unfortunately, a floppy card is missing and I want to connect a floppy to my MZ80b in order to run some CP/M stuff! As these cards are really rare nowadays I decided to make (clone) a DIY pcb from the sch...

I had been informed about this decoding scheme but with your clear explanation I finally understand it. Thank you. But , as I want to use only expansion port without the need of soldering inside I can use the MREQ with the following address decoding acording the new schematic below: mz-serial_MREQ.j...
