From: Tom Burnett Here are the Lobo Max-80 cpm 2 and cpm 3 disks CP/M 2.2 is a single disk (there were two copies) CP/M 3 is two disks - there were multiple copies. The CPM30USE disk is a bootable working disk i.e. no BIOS source, etc. Also attached are the files from the 2nd CP/M 3 disk with the boot rom, bios source, etc. as included in CP/M by Lobo Systems. Specifically, there were extracted from CPM302.IMD with cpmtools. I figured out the diskdefs entry by trial and error from the IMD information (tracks/sectors per track, etc.) and from a hex editor to figure out system tracks, directory sizes and the like. The Lobo cpmtools entries in diskdefs for cpmtools 2.9 are as follows (this assumes you've used Dave Dunfield's imd117 to make a raw track/sector disk from the imd file "imd /b filename.imd filename.dsk"): diskdef lobo2 seclen 256 tracks 77 sectrk 30 blocksize 2048 maxdir 64 skew 0 boottrk 2 os 2.2 end diskdef lobo3 seclen 512 tracks 77 sectrk 17 blocksize 2048 maxdir 64 skew 0 boottrk 2 os 3 end imd301.tgz is the extracted contents of cpm301.imd. imd302.tgz is the extracted contents of cpm302.imd.
