This may be of interest:

Jim

It shows the colour/probability distributions of an example page taken from an oxidised page. The result shows a clear overall RGB separation characteristic of ‘browning’. And raises on way in which this could then be used to help extend the greyscaled range of processed output.

Really sorry to hear you’ve not been coding lately, Michael. I’ve been really impressed with the stuff you have done in the past, and you’ve made a great contribution, so thank you for that. You may be happy in whatever you are doing now, and there’s nothing wrong in that, but if you are missing the coding, then I hope things will turn out better for you soon.

I’ve updated IPPTrnspt version 0.17 on my web site. The Messages and !Help files are all that has changed. The executables haven’t, hence the version number hasn’t. The new archive is 58172 bytes.

After some investigation I found to add a new printer a PrintDfn file should either be dragged to the Printer Control window, or just Double-click the PrintDefn file. Either of those works fine.

Ah, yes, thank you, you are of course correct. I’ll update the Help.

I have 2 of these machine 1. is a older first generation Iyonix which had its PSU replaced and has a dead IDE Bus the 2nd) is a later generation (probably the last they made with all the bug fixes on it and a newer (HiNT chip) that one is perfect, always works! even was treated to a brand new case 400W PSU and a 2nd PCI Network card. I wouldn’t ever part with it. But they are fragile machines for sure!

“Finally, be aware that Iyonixes are amongst the more troublesome machines to keep going (see Martin Eastwood’s problems). You may be better off with a cheap Raspberry Pi to play around with – it will likely give you better compatibility with old games etc via !ADFFS and the AnyMode module.”

If I would make the list the Acorn RISC-PC would be very high on the list ( actually higher then the Iyonix).

b) Yes getting the hardware to work and max out is much more fun than a Pi.

Again an update again on github . Important items are:
- Worked quite extensively on LibProp and I really had to do a few steps back because it was going nowhere. So at this moment only functions are in which are used in the BT stack. Empty functions so they have to be implemented over time.
- With LibProp compiling I could continue on the btdevctl application. The LibProb lib is now linkedin and now the focus can be on the other items which are not linking at the moment.

Indeed we see that BSD is often used by ROOL and ROD and it would be for the future good to see if one and other can be brought into a more standarized libray but for now I’m focussing on my own.

If all went well all the ‘o’ files are gone so Leo can be happy…

Starting and stopping mechanical drives are the hardest part of a drives life and will shorten the drives lifespan for sure, NAS based mechanical drives are designed for long term operation and are best left running. Otherwise whats the point? and i would say generally Mechanical drives are less likely to fail over a flash drive.

And always have spin up and spin down disabled. this too will shorten the drives life cycle.

I just wanted to say Thank you! to everyone here. I wish I could contribute with something, but as it is now I can’t. It has been several months since I did any RISC OS coding..

I hope I can find joy in coding again ,, Atm I don’t code at all.

Anyway½ Tanks again! And I love all your projects!

@Dave: I have been following the instructions to update my !IPPTrnspt to the latest version, having created an updated PrintDfn file. In the Help, after dragging the PrintDfn file to !IPPTrnspt, it says

Drag the same Printer Definition file to the Printers icon on the icon bar.

But when I did this, I got an error:

13:27:29.67 ** BASICError ** ERR=20 Number too big ERL=5855
13:27:29.67 ** WimpError ** from PrintEdit
  Error  : &00000014
  Message: Unexpected error :- Number too big (20/5855)

Thanks for the updates!

Worse thing you can do for a mechanical system is to keep starting and stopping it, resulting in increased thermal stresses. The longest time between failures of HDs is achieved by running them continuously.

Correction for Druk, I was not suggesting what would be a good use for the NAS to be turned off, my though (given turning it off has no benefits for security at all) was that the user might have been thinking of turning it off either to save some disks life or (eventually) save energy.

My NAS is always on, and disks spin down at night, I also reduce power consumption on the NIC ports (mine has quite a few 10Gbps ports), and the PCI bus (yes linux can control such things), but that probably requires a NAS that one builds by themselves (like I did). No idea if that’s possible with a proprietary NAS (I don’t use those, hence I don’t know).
