George: 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.

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? George Rachor ========================================================= George L.
