Search for 'm4 wristband' and you should find them (there's also an affiliate link in the Youtube description). Bear in mind that there are several very nearly identical ones, based on different architectures, so it's po

Hello --- I made this! Thank you for the kind words. I have, BTW, just received a $6.50 watch with touchscreen, microphone and speaker, much better build quality, BT 3, 4.2 and 5, plus the traditional fake heart rate sensor and a bigger bat

Adding Whisper subtitles was really easy and they're dramatically better than the automatic Google ones (I did it via https://github.com/abdeladim-s/subsai , which was trivial to use). So there is now a reasonably

Ironically enough, I agree. I loathe trying to get information out of videos. To pick an example _completely at random_: trying to get information on how to do video editing stuff with DaVinci Resolve invariably leads to a video, which is g

There is not, because none of it was scripted and any semblance of narrative flow was crudely faked in editing. But it's a reasonable request. I'll try pushing the audio through Whisper and see what comes out. Google will, eventua

Now I think of it... On the Master I could fairly easily extend the TPA up into the sideways RAM area, adding another 16kB, for a total of probably about 45kB. The difficulty is that filesystems in Acorn's MOS can't access sideway

Hello --- author here; thanks for the kind words! Responding to a few random things posted here: - yes, that 8080 emulator ought to work fine. Not sure what the performance would be like but it's certainly worth a try. Sadly, unless th

Sadly they're only available in the US, and it would triple the cost to get one sent to me in Switzerland! Fuzix would suffer from the same address space problem, however, but as there's no existing software for it it's less

Yes but no; yes in that you _can_ do that, no in that all available software has been built to assume that the base of memory at 0x0000. It can be done but there's probably not much point. Which is a shame as it's a really nice-lo

You might be interested in the TLCS90, which is an almost-unheard-of regularised Z80 with different and much more orthogonal instruction set. It's mostly source compatible with the Z80, although not binary compatible. If you want a mod

8080 compiler, actually, and I'm only using the ACK because there are no other 8080 C compilers. If you know of any others, please tell me!

Hello, author here. Thanks for the interest. If anyone has a candidate machine they want to port it to, please file a Github issue and I'll try and support you --- it's supposed to be easy to port, with a turnkey build system whic

Yup. As it stands, the license only allows that one site to distribute Digital Research code. That was almost certainly a mistake when drafting the license... but finding out who the current license holder is, and then locating someone will

I have a PX-8. It does work with tape, but very badly --- it's slow even for tape and painfully limited. It emulated a disk on tape, with automatic winding for access to multiple files, and required mounting/dismounting tapes or e

BTW, I have a branch of the FluxEngine client library which can also talk to a Greaseweazle, so if you have one of those you should --- soon, I hope --- be able to use the FluxEngine client to write Mac disks on a Greaseweazle.

Old-school IBM daisywheels actually have an exposed port for controlling them remotely. You can drive one with an Arduino and with sufficient lateral thinking you can draw graphics by microstepping and printing full stops. The protocol&#x27

They did add instructions when the programmers asked for them --- such as the famous EDRUPT instruction (whose use is still a bit of a mystery).

Hello, author here. It's a surprisingly modern-ish system, in many ways, and surprisingly weird in lots of other ways. One thing which really surprised me was a complete lack of pointer support: I managed to bodge the look-up-table ins
