You know, it's funny -- I am sticking with the 65816 for the Kestrel designs (my own homebrew 8/16-bit computer design, which I hope to bring up to the level at least of the Apple IIgs if not further, but being fully openly documented and GPLed), but I was thinking of a different homebrew line ...

I remember AmigaOS blasting away 20fps to 30fps, full-screen video, reading it in from floppy, in near real-time (in particular, I'm referring to Space Ace game, as shipped on floppy). It was obviously compressed on the disk, which made for faster I/O. Still, no other computer at the time could ...

Good work!

I'd love to build one of these but after some bad experiences with high voltages at uni involving a laser PSU, a hole in some insulation and my elbow (and the earthed desk) I'm too scared.

Sorry - my bad - you are correct:

%filesystem%::%volume%.$.%directory%.%directory%.%file%[/ext]

Got a stinking cold at the moment meaning my brain is lacking somewhat.

Never got the hang of Amigas - I had an A500 strictly for Xenon 2 and Speedball, not workbench ;)

The key misconception is that we think in terms of objects - our clients don't. They think in isolated chunks of genius and madness.

I'm all for lazy - that's why my brain churns on these things all day. If I can spend 6 months making the next 10 years easier, then I gain some of my time back ...

MOS = Machine Operating System

MOS is a single tasking OS for pretty much all Acorn systems with an fairly compatible API between 6502 and ARM systems. RISCOS is basically an evolution of MOS with a GUI on top which handles the multitasking side of things. They wrote it very quickly because they ...

Add note: I've been writing OO code since about 1993 (C++ -> Java -> C)

The problem that I encounter is not the tool or language, but that OO is not a good medium between machine and human thinking. We don't think in an object-oriented fashion at all. If you take an "uninitiated" person (as far as ...

Nothing particularly decent but there is some here: http://www.mdfs.net/Docs/Comp/BBC/

Most are in 80's books. It's not upwardly compatible but Acorn ported it to ARM in a week (!)

OO guru here and general strange guy (C# tech architect).

My thought on OO:

OO is an abstraction of thought, and a poor one, not of a machine or how the data is actually organised or should be. Sometimes the mappings are terrible (particularly on the e-commerce platform I run but we've had to ...

Anyone looked at Acorn MOS? That was a decent modular OS for 8-bit machines (6502 specific). Covers multiple filesystems, multiple interpreters etc and networking!
