Dear Albert, Thank you. Let me be among the first to welcome your kind offer of to disassemble CF2a as you did CF01. Moreover, the the addition of a high powered assmbler like yours would be useful for instance in my music project: certainly fast 64 bit addition in Real Time CPU Clock, and possibly floating point for wide dynamic range. Even 10 screens for your full assembler would be very little extra, seeing that my own project already has 90 screens of 'synth' and 360 of 'score'; anyway the 10 screens would be loaded only when required. As regards 'official' versions, I am afraid Cf is not Linux: it is not officially open source, there are no official maintainers, there is no contract with Charles Moore. I take what I can, and am grateful. CF01 came from the website of CM, as open source plus disassembly by CM, with subsequent mods and further disssembly by others - including your esteemed self; CF05 arrived via Jeff Fox, again with mods and disassembly by others - the one by Josh Grams is the one I use; and now CF2a comes without a disassembly from 'the Okad team', which seems to be a commercial enterprise allied to Intellasys which makes CM's parallel Forth cpu chip, where their present interest and future hopes lie. I tried to 'Run' your old reassembly of CF01 (color.com) on my wife's XP Winmachine - no use. Unfortunately my old Win95 machine has died - the one that ran Chuck's original CF01, and started me off. But my subsequent experience with native CF01 and native CF05 has conviced me that native colorforth is inherently stable - once you have a disassembly to identify the few parameters that need to be 'peeked' and 'poked' (mainly in VDU). After that, it is a hobbyist's dream: a self booting OS with VDU, keyboard, number dump and source compiler, access to the pci bus, no hidden interrupts and no hidden BIOS tricks - all in less than 12k plus a few k for graphic icons! Hence my continued interest in booting from native CF2. Plus the possibility of a full Intel assembler in only 10 more k? Caritas, Nick **** It is the buying power of the currency that matters, not the size of reserves that hardfaced men have built up for themselves by financing the war. - 'Keynes' (sic) on a CIF blog.
