Altair hard disk system

        The emulator presently supports two formats using only an emulated 88-DSK
controller. First is the base Altair disk format with a capacity of about
337k. This format is also used for CP/M 2.2 (although the sector size is
different). The second is a special 1mb "large disk" CP/M format.

        The project screams for a hard drive setup but there were very few at the
time. So, that's why we came up with the 1mb large disk CP/M format.

Rich, and others..

I have a set of formatted disks from this era for the Altair but no
hardware available.

I saw the Altair emulator project. I'll someday either need to get real
hardware <grin: not likley> or a way to get my diskettes imaged such that
I can access their contents from the emulator.

What does the emulator currently support in the way of disk images?
