Unfavorable Content

Large portions of this article are autobiographical and don't provide citation notation. In addition, the phrasing used in the article tends to shift from that of an encyclopedia at many points. Revision should probably take place. Masquatto 20:50, 3 September 2007 (UTC)

Rebol 3.0

"Sassenrath is currently in the process of implementing the next generation of REBOL, V3.0"

This may have been true when last edited, but through 2011 to date it cannot not be confirmed to be true given the state of the project ( the RMA partners and the rebol-red language project.)

See dates on his last posts to the Rebol developer community at rebol.net under Carl blog and Rebol3 blog.

I do not believe that either the nature or the the name of his current project or partners/employers/clients is public knowledge.

Some information is public at the Rebol Altme "world" forums at rebol3

2012 - edit long overdue

I don't wish to be the one to do it, but really,

"Sassenrath is currently in the process of implementing the next generation of REBOL, V3.0 (which was due out in 2009). "

First, it is now June 2012

Second: I only know of one Rebol developer with occasional contact with Carl and there is no reason to believe that Carl is working on Rebol 3.0

Amiga Computer: no credit to TRIPOS

The Amiga OS was built on top of TRIPOS. This section implies that Amiga OS was built from scratch by Sassenrath. No mention of a team and no mention of TRIPOS.

The section says multitasking was a novelty and a challenge. TRIPOS supplied the multitasking.

As far as multitasking personal computer operating systems: I think that Apple Lisa did multitasking earlier, but I'm not sure that it multitasked. QNX did it earlier. OS-9 did it earlier. MP/M did it earlier. Cromemco's Cromix did it earlier. Those are just off the top of my head.

Amiga may have been the first personal computer bundled with a multitasking OS that was successfully mass-marketed. That definitely was a milestone. DHR (talk) 00:02, 21 January 2020 (UTC)

Note that the Sinclair QL, released in January 1984 (about 18 months prior to the Amiga) had a preemptive multitasking operating system, Sinclair QDOS, and is considered the first microcomputer (aka personal computer) to come native with one (Sinclair Research's goal was to create a workable Unix in less than 64K of ROM). The QL was not a market success, being retired at the end of 1986 after Sinclair Research was sold to Amstrad, though a modern version of QDOS exists called SMSQ/E. The creator of QDOS was Tony Tebby. 65.96.60.19 (talk) 10:27, 22 February 2021 (UTC)

I think you are conflating "AmigaOS" with "AmigaDOS". The latter names only the disk operating system part: "dos.library", hunk format and the command shell. Those had indeed been based on TRIPOS, but TRIPOS did not get into the picture until after development of what had been supposed to have been AmigaOS's native file system "CAOS" had fallen too much behind schedule. Development of CAOS had supposedly been outsourced.

AmigaOS wasn't officially named "AmigaOS" until release 3.1, which wasn't long before Commodore folded. That Sassenrath's EXEC had been based on many of the same ideas as TRIPOS' kernel is evident, though — and is a reason to why TRIPOS' code could be ported to the Amiga so fast. The differences in style between dos.library and Exec and other libraries is evident if you look. The TRIPOS parts are the only parts of the operating system that contains BCPL-isms.
