If you have a faithful Acorn Risc PC kicking around you might have found that the rubber feet on the bottom of the case have started to crumble, like mine:

In some cases the rubber feet can even liquefy and leave you with a wonky computer sitting in a pool of grey goo.

You’ll be pleased to know that you can lever off the old ones and replace them with a new set of Bumpons (that’s what they’re called) from 3M.

PrivateEye 3.01 is now available. This includes a fix for filing systems which don’t provide predictable sequence numbers. Previously using Page Up or Page Down to flip between images when using a filing system such as FAT32FS could bring them up in an unexpected order. PrivateEye now rescans the directory on each flip to find the previous or next image as requested.

Since it’s a minor fix I’ve not updated the PDF manual.

It’s been swelling, building for a while and now the time is right for a massive dump .. of links related to my project to reverse engineer The Great Escape.

An update to my RISC OS image viewer PrivateEye is now available with a couple of small but essential fixes for anyone using a Raspberry Pi 3, or using a version of RISC OS with zero page protection enabled:

• It avoids crashes on the Raspberry Pi 3 by fixing a previously undetected MOVS pc instruction. It appears that the Cortex-A53 faults these instructions; a change from earlier cores.
• There was a NULL dereference in the choices handling code when the user clicked on a pane containing hidden choices (those without a UI). This would cause a crash on zero page protected OSes.

Additionally it was rebuilt using the latest DDE27 tools from RISC OS Open Ltd.

There have been a couple of recent changes to the ARM courses. Here’s a summary (with reporter in brackets):

• Introduction to ARM > Barrel Shifter
  • The ‘ASR’ diagram was wrong: corrected. (Bruce Robertson)
• The Introduction to ARM diagrams have all had 2x and 3x scale versions added for the benefit of those using retina/HiDPI screens.
