I'm just fascinated with how clever these are. I discovered them about a year or so ago, and find myself coming back every few months to play with them again.

Bravo!

Hello! I do have a draft version in digital form. I'll try to find the time to add the final touches (currently in pencil) and post the complete score here.

Hello Linus! Have you then found the time to refine the sheet for your beautiful Triple Fugue? I'm really interested in a copy of it, if possible. Thank you very much.

Yup, interesting intro to the TTY area, I think, and fun trying out the terminal tweaks..but any ideas of where I can find a good intro to using TTY in Linux, without the writer assuming I know all about networking/the Linux kernel in advance??? Please and thank-you.

GCR decoding on the fly

Anonymous

I just had an idea, why bother with decoding GCR at all, how about you use the GCR raw bytes as an index to a 256 byte table to return a 6 bit result. The original bits would have to be scrambled quite a bit resulting in a specially encoded file.

Also, do all the bits occur in order to select some subset of the bits in the GCR? For example, just mask every other bit and call that your decoded data.

Extend this bit mangling even further, make up a new encoding that gives even 2 decoded bits per byte that are stuffed directly to the output (in a 2bit transfer). This is quite wasteful of space however and reduces the data rate quite a bit, but is trivially fast to send and decode.

Those are nice ideas, especially the first one. It would slightly reduce the amount of information you can store in a block (6 * 320 / 8 = 240 bytes), so any benefits would have to be weighted against that. You'd also probably want to buffer the data as 320 bytes, either before or after the table lookup, and then transmit each byte as three bit pairs. It's not obvious that a good mapping function actually exists; it should fit into a single page, so the same mapping should work regardless of the alignment between gcr chunks and bytes, even if the encoding would be different for each alignment. I'll think some more about it.
