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

There are several "layers" of compatibility requirements, like (this is not an exhaustive list): - mechanical - does the card physically fit into the connector on the machine? - electrical / signals - does the machine have the signals that the card requires (and vice versa) on the correct pins? - lo...

Re: Unicard - is it possible to get it?

I see. Are you using the same connectors for both ends? (It looks like that on your picture).
Do you have a part number or a source for these connectors?

Re: Unicard - is it possible to get it?

So, is the schematic for the bus converter available?
Or the difference between the bus on the MZ-700 and the MZ-800?

Re: Unicard - is it possible to get it?

is the schematic and / or PCB layout for the mk3c version available for us MZ-7xx owners?
