Disk: Zilog MCZ
===============
The Zilog MCZ is an extremely early Z80 development system, produced by
Zilog, which came out in 1976. It used twin 8-inch hard sectored floppy
drives; here's one at the Centre
for Computing History:
The MCZ ran Zilog's own operating system, Z80-RIO, and used 77 track
single-sided disks, with 32 sectors (each marked by an index hole), with 132
bytes per sector --- 128 bytes of user payload plus two two-byte metadata
words used to construct linked lists of sectors for storing files. These
stored 320kB each.
FluxEngine has experimental read support for these disks, based on a single
Catweasel flux file I've been able to obtain, which only contained 70 tracks.
I haven't been able to try this for real. If anyone has any of these disks,
an 8-inch drive, a FluxEngine and the appropriate adapter, please [get in
touch](https://github.com/davidgiven/fluxengine/issues/new)...
Reading discs
-------------
Just do:
```
fluxengine read zilogmcz
```
You should end up with an `zilogmcz.img` which is 315392 bytes long.
