That's a great history. I did spot some small errors: > Tim Paterson at Seattle Computer Products had developed a reverse engineered CP/M for 8086 S-100 bus microcomputers, DOS-86. You have the name backwards. It was 86-DOS. https://en.wikipedia.org/wiki/86-DOS https://en.wikipedia.org/wiki/86-DOS > Lineo eventually sold to DeviceLogistics in 2002. DeviceLogics. https://en.wikipedia.org/wiki/DeviceLogics https://en.wikipedia.org/wiki/DeviceLogics > The last versions were DR-DOS 8.1 and EDR-DOS 7.01.08 WIP 2011. Hang on. This is conflating 2 entirely separate lines of development. DrDos Inc continued work and released DR-DOS 8 and 8.1. However, it was shown that they used code from FreeDOS without giving credit and without releasing the source. The product was withdrawn. Earlier, in 1997, Caldera released some of the DR-DOS 7.01 source code under a permissive but not FOSS license: https://www.zx.net.nz/netware/drdos/caldera.shtml https://www.zx.net.nz/netware/drdos/caldera.shtml It changed its mind and withdrew it again as of 7.02, which was once again closed source. (Apparently the company found some old Novell backup tapes and was able to re-incorporate some Novell bug fixes which had been lost.) Udo Kuhnt picked up this open source, and continued enhancing it. That is where Enhanced DR-DOS comes from. It's entirely separate and parallel to DrDos Inc's work on v8. > From Lineo forward it would appear that Udo Kuhnt was the lead developer/manager. He was an independent FOSS developer working on the open source code for the DR kernel 7.01. He had nothing to do with Lineo at all. (AFAIK!)
