Re: Python Assembler Query - RAM labels
There isn't any such mechanism - asm.py doesn't really know much about memory at all. Depending on what you are trying to achieve you might be able to use the way in which the hi() and lo() functions work - they evaluate to 0, but also record the ROM offset where they were called, and the label they...

Re: A Forth for Gigatron?
Thanks. Perhaps it would be useful to let people know where I'm at with the Forth effort. Right now the progress is hard to see - to date there isn't anything that is directly runnable on real hardware on an emulator. However I have quite a large part of the system implemented - including 34 of the ...

The Ultimate Acorn Archimedes talk
I just watched this talk from 36C3 on the design of the Acorn Archimedes computer, and I really enjoyed it. I thought it might be of interest to people on here. In particular I was fascinated by some of the details of how how the chipset was designed to fit within constraints of pin-count on package...

Re: A Forth for Gigatron?
You weren't kidding when you said that writing Forth in native code "will be a big undertaking, especially as a first project"! I thought I should just post to say that I'm still trying, and making steady if unimpressive progress. I think I have the timing sensitive code done (at least for...

Re: Atari 8-bit architecture and homebrew versions
I might add that I thought the final image was less than classy, and subtracted from the otherwise impressive feat.

Re: Atari 8-bit architecture and homebrew versions
On the subject of the Atari 2600, I recently saw this demo which I thought was really impressive considering the severe limitations of the hardware (and also I love the music). It did get me thinking what a demo scene production for the Gigatron could look like - with clever coding it could probably...

Re: A Forth for Gigatron?
Well to answer the original question, is there interest in Forth on the Gigatron, it seems clear that the answer is 'yes'. I must admit that I've been well and truly "nerd sniped". Of the three paths of v6502, vCPU , and the 8 bit Gigatron CPU, it seems clear that the v6502 is the path of ...

Re: A Forth for Gigatron?
Surely the more interesting hack would be to target the real Gigatron CPU, making the FORTH "runtime" effectively a third virtual CPU. I've never written a Forth before, but I've been thinking about doing it a lot recently. The Harvard architecture presents some challenges (although no dou...
