Creating a sharp MZ80k Basic master disk (or any other disk)

Post by Steve_Doo » Wed Feb 06, 2019 11:35 pm

Hi All

I have successfully rebuilt my MZ80k, I/O box and floppy drive unit.

I can create and load tape based programs fine through the cassette, however, I am at a loss on how I can create a master boot disk.

ANy advice would be appreciated!

Thanks

Steve

There is a big hole in the knowledge here it seems when it comes to disks. I'd like to know how to make a bootable disk with my own programs for the 80A. Maybe the SUC has some information. I only have two bootable disks, SA-6510 and CP/M. There must be a utility somewhere that can create a bootable disk. Will do some research.

On the SFD700 version 2, it was enough to put the IPLPRO chain in the first sector of the first track at the 0 offset of the disk to boot. Maybe it's a similar case here.

your proble is, the MZ80K has anothe Floppyformat than the MZ80A or other MZxxx.

If you have the original hardware, you have an single-side floppe, all other double-side.

The dataformat is different, so you nedd real an MZ80K with disks, or you must rebuild then from the MZ80K masterdiskimages.

Problem: you need an PC with old 360K drives !! But you can conect your 80K drive to the Pc Via diskinterface.
