@xerz I *almost* had this? My S16X4 family of homebrew CPUs have fewer than 16 opcodes, so it was pretty easy to memorize instructions by number. No assembler needed! Just edited raw hex dumps . :)

@Azure If only Khan were so motivated in Star Trek II: The Wrath of Khan, imagine how different that movie and subsequent films would've turned out.

@cstrotm m68k was a big-endian architecture. What does "little endian mode" mean here?

So, I looked at EmuTOS source code this morning. I don't think I'll be porting this software to the #Kestrel3 . Reasons include:1. As I expected, it is tied tightly with the m68k architecture. And, that's OK; it does what it says on the tin. I just was hoping that some of the footwork for making it more portable has already been done.2. There is no migration plan; nothing to tell me, "Start here." Tripos, however, does have at least *notes* to this effect, which is very helpful.

What I am thinking for the #Kestrel3 going forward is I should port Tripos (yes, that means system software will be written in BCPL, not C) to get *something* working.Then, try to bring up a GUI environment within Tripos. It won't be compatible with GEM, but I envision it would share its essential features (its overall architecture, for example) along with some repairs to GEM's architectural deficiencies (8.3 filename limitation, single-click latency, etc.).

I might even take some architectural cues from Plan 9 and Rio.Whichever is easier to get off the ground and working sooner.

@bhtooefr @cstrotm OK, now that just invites whatever scorn they deserve. ;)

Just a reminder: if you're looking to follow me because of my interests in libre hardware and software hacking (including but not necessarily limited to #fpga, #Kestrel3 and #kestrelcomputerproject , #rc2014, and so on), you might also be interested in following my @vertigo account as well. I will slowly be migrating that way.Thanks!

FINALLY!! Spotify finally found a Pink Floyd song that caters to my warped sense of musical tastes. (See Emily Play, if you're wondering.)

@sean I'm so old, I remember when Freshmeat.org was a thing. Too bad it's gone now. Le sigh.

@vertigo @EdS Dang it, I don't need another project!Now you got me thinking about revisiting the Kestrel-2 design but with a processor friendly to BCPL!!

OK. I'd like to write some nMigen code to formally verify my ancient KCP53000 ALU design. The one that takes up a full 1/5th the capacity of the LP8K FPGA? Yeah, that one.Let's see how far I get.

I will give myself four hours; then I'll need to move on to other things.

@thamesynne @mdhughes @djsundog This is *literally* the premise behind both the original Tripos/BCPL programming environment, as well as the IBM OS/400 operating system environment.

@wilfredh """Instead of a flow of code that issues syscalls when needed, that have to think about whether or not a file is ready, they naturally become an event-loop that constantly add things to a shared buffer, deals with the previous entries that completed, rinse, repeat."""And, Amiga developers the world over read this and ask, "What took you so long?"
