Raspberry Pi release the Pi Zero W in 2017, and the Pi Zero 2W in 2021; so when do we think that the Pi Zero 3W will be released ? Soon ?

At a HardOff I caught a glimpse of an oldschool Japanese mechanical typewriter. The Nippon Type PanWriter types in 3 colours and somehow impacts one of the over 2300 glyphs onto the paper after the user manually slides over the rows & columns and presses down to type it. (Zoom in for the details)

I was switching between Famicom & PCE/TG16 games and was annoyed at how PCE screens were shifted to the left compared to Fami. So I did some measurements: the Fami's active pixels start ~7.6us after the end of HSync while the PCE's can be 7.0us (early) or 8.47us (late), but never the same as Fami :/

It would be nice if BlueSky had an intermediate choice - for example, people who follow me for a certain period of time first (or something like that).

Apparently, I'm not finished with the XE-1AP/CyberStick code on MiSTer.
Christoph Smaul showed me that there is a protocol difference between "computer" and "console" settings on the XE-1AP, and a converter is needed to use the CyberStick on a MegaDrive.
