Re: Odd Peripheral Goings-On With RPi4

If you start with no keyboard and then plug one in after a while, does it get recognised?

Same with monitor?

Re: Lost RISC OS Econet, AUN and NFS software

Are the other items listed in the first post still "lost"? If so, I can have a good trawl; what version numbers would I be looking for?

Re: Lost RISC OS Econet, AUN and NFS software

Since it appears to have now been found, I decided to make a concerted effort to find it myself, and discovered I had it all along!!!! on my main MDFS under !ArmBoot.Resources.!System.Modules.

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

It's interesting to learn about the history of the BBC micro disc interface. Until now I'd never really given any thought to the capacity difference between 8" and 5.25" discs, I think I'd always thought that an 8" BBC micro floppy disc, if one had ever existed, would just be 80T 200K in DFS like a ...

Re: Odd Peripheral Goings-On With RPi4

I've tried with the USB storage devices plugged in directly without the USB hub, with the same results. I can't try without using any USB at all just at the minute because there are 3 USB storage devices attached and it won't boot without all of them, I would have to faff about with my fstab file to...

Re: Hmm.. was there ever an 8" floppy drive for the BBC?

D1000B.IMG is a corrupt DFS disc image containing one file. The catalogue and map at the first two sectors have been overwritten with zeroes, then a BASIC file starts at sector 2 which is attached.

Re: Odd Peripheral Goings-On With RPi4

It is a USB3 hub going into a USB3 socket. I''ll try without the hub and see if that rules anything in or out.

I've now had the second Pi4 out, and it exhibits exactly the same behaviour as the first one, so I think we can rule out a specific board or other fault on the first one.

Tried that now and can report the same "good behaviour" with cable plugged into the second HDMI socket and going to an HDMI input.

Re: Odd Peripheral Goings-On With RPi4

I'm going to say that all this is something to do with the HDMI.

HDMI sockets ...

Re: Odd Peripheral Goings-On With RPi4

I'll look into that. I've just been doing some more testing, and it's very unlikely to be a heat thing. With the monitor connected, but not keyboard/mouse, my GPIO keybind always works. GPIO shutdown also works. With monitor not connected but keyboard/mouse connected, GPIO keybind doesn't work, but ...

I don't think it is a heat thing after all. I added the GPU temperature read-out to my cron and it doesn't go above 70 degrees. I've dumped an old PC fan on top of it and it's down to 35 degrees now, but after under 15 minutes powered on, I tried my GPIO keybind shutdown and there was no response. I...

Oh yes. I am sure I was probably thinking in terms of sectors when I was mentioning tracks.

This is a great find! The FileStore code version 1.25 seems to bear out my theory that it was based on the Level 3 file server (latest version known 1.24) and Acorn probably carried on the same numbering. A bit of "Edit" seems to have crept into the end of that file - it has the text referring to De...

Re: Lingenuity (Wild Vision) SCSI podule ROM

Thought as much. I've opened it now, and there's no clue on the disc surface to show where the metal bit might originally have been. As it's a DD disc I'm guessing it will be ADFS 800K format- can those be read on a Master? If I can tack it back together and then get the data off it, which might not...

Re: Odd Peripheral Goings-On With RPi4

I added gpio-shutdown to GPIO 21 and that works in all cases, even after GPIO 3 or keyboard, monitor etc. fail to respond. So it seems like there is a fault with whatever drives the video and USB. I'll have to try my second Pi4 to see if that has the same problem.
