Re: ST506 HDD woes

Have tried the usual anti-stiction trick of a quick half-turn around the spindle axis... I think it's worth applying this rotational shock to any ST-506 drive that has been powered off for a while, before powering it on. I powered on such a drive and it didn't spin up, and it then proceeded to move...

Re: RISC iX on ST506

5. Version 1.5 of st506form2 sets up a 10MB Swap partition by default, even if that means a stupidly small Root, and seems to want a free cylinder between partitions (RISC OS given 16 cylinders staring at 0, which should be 0-15 inclusive, but RISC iX Root starts at 17 - I saw spare sectors under s...

Re: RISC iX - Cloned!

The flashing border normally indicates that the contents of one of the (other) virtual terminals has changed. Use <Break> and the cursor keys to toggle between them (see R140 Operations Guide page 37). You can press N on the menu screen to disable the border flashing.

Re: How to compile Arculator for Windows

When HFORM-iX asks for the desired swap partition size, this is only to calculate a suitable number of cylinders to show as the default for defining the second partition (which would normally be swap on a standard installation with one disc).

Re: How to compile Arculator for Windows

Hi Pollito, Yes, it's quite fun to play with! I think (though I could be wrong) that it's necessary to have a Filecore partition on each disc, because this contains the offset to the RISC iX section, which is read by RISCiXFS on the RISC OS side, and then passed to the RISC iX kernel. Also, without ...

Re: Mouse repair tip

I used these LEDs from Rapid: https://www.rapidonline.com/Electronic-Components/Kingbright-KM-4457F3C-Side-Infrared-Emitting-Diode-72-8966 They are 2-pin components, but the third pin on the old parts is just common with one of the others. A bit of leg bending may be needed but they definitely work!

Mouse repair tip

My two RiscPC mice from 1994 both stopped working in one axis, and it turned out that the infra-red LEDs had become weak. They work fine now with the LEDs replaced. Perhaps it's a common failure? Also, cheap Chinese USB mice from Poundland (or similar) are a good source of suitable replacement micro...

Re: RISC iX on Raspberry Pi

Hi pollito, sorry for the slow reply. The distribution of RISCiX disc images is a bit of a legal grey area as technically it's still commercial software, although quite who owns it is anyone's guess. Obviously an image is already out there, though, and RISCiX has not been available to buy or even su...

Do you know if for ST506 support the drivers need the Acorn interface (A4xx) or the Acorn AKD52 podule (A3xx)? I have a non-acorn ST506 podule (can't remember what brand now), should that work or are the RiscIX drivers specific? I don't know, it's worth a try! The podule will contain the same HD634...

Re: RISC iX on Raspberry Pi

Rob, for full details see here! Then it's just a case of copying the prepared disc image on to the Pi SD card, together with ArcEm.

Derek, RISC OS 5 runs natively on the Pi - but an Archimedes emulator is needed to run RISC iX. So in this case, RISC OS 5 is just there to run ArcEm.

RISC iX on Raspberry Pi

Well, after installing RISC iX on an ST506 disc image, I had to try it (emulated!) on a Raspberry Pi, using ArcEm running on RISC OS 5 to emulate an Archimedes with RISC OS 3.

It works!
