MZ-80B project (Floppy Disk I/O Card cloning!)

Post by dat-alex » Mon Jun 03, 2019 11:23 am

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 schematic [url]http://web.archive.org/web/201509262024 ... 80b_sm.pdf

I would like to ask if someone has a better-scanned service manual or willing to make a hi-res scan of his mz80FI card in order to have it as a guide trying to guess... the low-res printed pins of the service manual.


Thank you in advance
Alex

Unfortunately, I don't have a better manual, or a MZ-80b / floppy controller card.
Are you trying to redraw the schematic and do a new PCB layout?

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 autoroute works better I think.)
