Re: PyCon UK Talk Proposal
Thanks Walter, I'm glad and relieved that you enjoyed it. I was a bit worried that you would think it was inappropriate for me to talk about your friend Marcel as I did at the end, since I didn't know him beyond a relatively few messages exchanged online. I really do feel a great deal of gratitude t...

Re: PyCon UK Talk Proposal
The talk seemed to go quite well, all things considered, and I had a lot of interesting conversations around the conference.
The video is here. The time slot was quite short, so I couldn't cover a lot of what I'd have liked to, but I think it was at least coherent.

Graph Paper
Inspired by the back of the BBC Micro User Guide, I've written a PostScript program to generate Gigatron Graph Paper. Basically it's a 160x120 grid, but it's annotated with the default memory addresses of the pixels. It needs to be printed on A4 paper (sorry to anyone in the USA). I've attached a PD...

Re: PyCon UK Talk Proposal
Yes, I absolutely will. The talks are usually recorded and uploaded to YouTube.

Re: PyCon UK Talk Proposal
Due to a cancellation, it looks like I'm now going to be giving this talk. Hopefully I'll manage to pull the bunch of loose ends of my various projects into something coherent in the next month!

Re: PyCon UK Talk Proposal
It wasn't accepted - although I wonder if it got close, because I'm aware some people got their rejection emails quite a lot earlier.

CP/M (now) under OSS-like terms
I'm not sure if this is of interest to anyone, but I know that at one point Marcel had ideas about making a v8080, and porting CP/M to run on the Gigatron. Apparently it had been released some time ago, but under a license that had some apparent restrictions on how it could be distributed, and thus ...

Re: Debugging symbol format
That's interesting. I'd not heard of stabs. Source code debugging is the sort of use case I was thinking of building up to. For now, I think just being able to replace addresses with variable names while stepping through instructions would be very useful, but I'm approaching it with a GCL mindset, w...

Re: Debugging symbol format
Thanks. Presumably your debugger also makes use of some non-public symbols (specifically ENTER and NEXT) for single stepping vCPU code.

Debugging symbol format
I've been wondering if there might be value in coming up with a format for debugging symbols for ROMs and for gt1 files, if one doesn't exist at the moment. Obviously there's the interface.json files, which define the public interface for a ROM, but there's a lot of points of interest that are defin...
