@lukeweston Just reminded me of early endeavours with LinuxCNC and using a parallel port to generate stepper motor pulses.

First use of @usgraphics Berkeley Mono on a control panel.

@cra451 @emm0sh @beaversteever What about the damages after it caused a collision with a pedestrian?

@visitnorthyork @astronomer14 They don't have to. If all black panels, rather than those with bright silver trims, are sunk into a tray that positions them level to the roof, they're far more subtle and harder to spot unless you go looking for them.

Another project using the lovely PTFIX distribution terminals from Phoenix Contact.

Turns out DisplayLink supports run length encoding, and now, so do I. This is EGA from a Pi Pico 2 on the ISA bus, using DisplayLink over USB 1.1 as the output device.

@MehdiHacks @ElecNotes Spinner make very nice adapters. I picked up some N to 3.5 mm which are beautiful and weren't that expensive (maybe circa 35 Euro each IIRC). Ordering was via email and account setup, but was pretty painless.

@usgraphics Been wrestling with an IBM DS8800. The smallest + cheapest reliable array I could find that supports FICON. Its HMC laptop is slow to boot, then the array takes ~30 mins to start up. A labyrinthine world of terminology, codes and procedure.

I seem to have a habit of picking the hottest days to do the least suitable tasks. This weekend it's metal bashing. A few years ago it was running a multi-day AI model training job on 2x GPUs in the office server in the midst of a heatwave.

This nibbler is a bit scary effective.

@BoscoMac I'm just setting one up with a Hacker Gadgets CM5 upgrade. Tried ClockworkPi-DragonOS-6.12.67 and had no display output, but I need to re-check cables first and then might give that a go if no luck.

[Andrew Back @9600]

@F4DAV @cederom @LimeMicro @crowd_supply @MyriadRF I'm not sure that there would be, other than the relative compute performance of one platform vs. the other.

[Andrew Back @9600]

Excited to be able to share details of something Lime Microsystems have been working on! LimeSDR Micro is a new compact, low cost SDR, with integrated baseband processing courtesy of NXP LA9310, available in M.2 2280 and mPCIe form factors.

@davepl1968 @sdf_pubnix ITYM before the Web. The Internet existed long before that.

[Andrew Back @9600]

@MehdiHacks Right, it's just like CLIs and real terminals. Single function, and a low fatigue, distraction free UI.

[Andrew Back @9600]

@mcdermottkc_ @SarahLudford Least bad viable option.

[Andrew Back @9600]

@davepl1968 I raise you IPLing VM on an emulated IBM System/370 mainframe running on a Nokia N800:

Also had a GSM core network on a Sony smartwatch via AsteroidOS, which was fun, but not very practical (run out of juice or bad WiFi and your cell network goes down).

@Talha_Jamil @mcdermottkc_ Streeting would be out of the frying pan and into the fire. Many dislike him even more than Starmer.

Viewing >100 MHz of spectrum with the compact, low cost LimeSDR Micro M.2 SDR + GNU Radio.
