Latest Raspberry Pi – Psion MC400 Sidecar update

So I’ve made a few changes from my initial build of my adjunct/sidecar Pi to get some connectivity into my Psion MC400 – now running on a Raspberry Pi Zero 2W in a flirc case with Zero4U 4-port USB hub underneath and pimoroni inky pHAT e-ink display on top… It looks super-cute and all the fonts/icons shown on the display are captured bitmaps from the MC’s GUI – I wanted to make it look as “original” as possible.
(PSION logo bitmap is actually from the original Series 3 ๐Ÿ˜‰ )
I love the crispness of the e-ink display ๐Ÿ˜ ๐Ÿ˜Ž
Say hello to the “inky sidecar”….



I created a service “inky_update” on the Pi to monitor the status of a few Psion-connectivity options and update the bitmap on the e-ink display only when something changes

bitmap showing status of internet/terminal/File-Link

The “Modem” and telephone icon are just a visual proxy for ‘Internet connectedness’ – back in the MC’s day there was no notion of networking on the machine so “modem” and telephone are as close to “Internet” as we can get in original MC400-speak ๐Ÿ˜‰

Who knew watching mono bitmaps appear/disappear and get sync’d to Gdrive was so thrilling ๐Ÿ™‚

(And sincere apologies for my lack of videoing skills; talking/typing at the same time whilst waving the phone around ๐Ÿ˜ฌ ๐Ÿ˜ฌ ๐Ÿ˜ฌ )


Another service “inky_shutdown” displays the Psion logo just before shutdown of the Pi, because why not? ๐Ÿ˜Ž ๐Ÿ˜Ž ๐Ÿ˜Ž

…on Pi shutdown the Psion logo is loaded to the e-ink display ๐Ÿ˜Ž

Checking inky_update service status
Such a cute stack ๐Ÿ˜€
