The one that he sent me is a HardBox. The HardBox and the SoftBox are the same hardware with different EPROMs and minor configuration differences. The HardBox provides a CBM DOS interface to a Corvus hard drive. The SoftBox is a CP/M computer. It can optionally use a Corvus under CP/M but the Corvus can't be used as a CBM DOS device. I compared the HardBox and SoftBox boards and worked out the differences. I was able to successfully convert a HardBox into a SoftBox and run CP/M on it. Steve Gray has done it now also. > I never was able to do anything with them because I couldn't find any info > on the internet. I have both types working now and can help. Anders scanned the HardBox manual and made a disk image with the utilities. Those are on my site now. I was able to format a Corvus drive on the HardBox using the disk. Almost all of my work has been on the SoftBox. I got the disk and manual from former employees of Small Systems Engineering. I had the disk for many months before the manual was found. During that time, I disassembled the Z80 BIOS and most of the utilities to find out how they work. I now have a good understanding of the SoftBox internals. I have posted dumps of the EPROMs that I have. Please check if you have a different version, especially if it is a SoftBox.
