Hi everyone,

Leeb, I'd confer directly with Fred or Andrew, but the image file on the SD card is generated from the XTRS emulator. So in theory if XTRS can be used with CP/M then there is a good chance it will work with the FreHD drive.
Hi.
This is Fred, the designer of this emulator. To answer your questions : the emulator simulates the WD1010 interface to a Z80. The SD card is used obviously for storage, but not in raw mode. So you can have multiple hard drive images on the SD card. Currently, the emulator mounts up to 2 files (RSHARD/DCT supports only 2 files), but a simple re-compile can make it support 4 files, like a real WD1010. To the computer, the file appears as a real hard drive...
This has a little overhead, which is compensated by the ease of use. You can prepare your hard drive image on an emulator (I did everything with 'xtrs', from Tim Mann), copy that file to the SD card, and use it on the real machine. It is extremely convenient.
Regarding CPM, I haven't tried. But Andrew (a friend from NewZealand, beta-testing and developing utilities for the emulator) or I would be happy to test a CPM image. Prepare everything on 'xtrs', send us the file "hard4-0" and instructions, and we can test in a few minutes...
Your last question is "boot from...". If you can boot CPM from a real hard drive (on 4P ?), then it will probably work the same on the emulator. If not, too bad. I am considering starting an effort to hack the ROM to allow to boot LSDOS from the emulator, but that effort hasn't started yet (and I am getting very busy @work and with another project... that's also the reason why I decided to put all this as open-source, so people can modify/enhance and distribute..)
Cheers
