So recently I have been playing with one of my retro toys the Sinclair QL. This is the strange beasty Sinclair built after the ZX Spectrum, 68008 CPU which is familiar(ish) to Amiga/ST owners. So far I have a SuperHermes replacement serial/keyboard board fitted. To one machine that allows the use of PC keyboards. Another machine has the most excellent QL-SD fitted. Like other Retro platforms there are also new hardware manufacturers appearing like Sandy. Waiting for my SupraRAM to use with the QL-SD!

Enter the Volcano | World of XorA
http://www.xora.org.uk/2015/06/08/enter-the-volcano/nggallery/slideshow
Being in Iceland this was the essential trip to make, to go down into the magma chamber of an extinct volcano. The trip starts with a quick 3km hike across an old lava field to base camp. We hadn’t counted on this being the coldest spring for 30 years though and the lava was still covered in snow. Waiting for us was one of those window cleaner thingies you see on the side of buildings. Slowly it lowered us into the volcano core where we could finally see what we had come for.

Acorn Electron ROM Cart to Sideways RAM part 2 | World of XorA
http://www.xora.org.uk/2013/05/22/acorn-electron-rom-cart-to-sideways-ram-part-2
Acorn Electron ROM Cart to Sideways RAM part 2. So I had a rethink about the Sideways RAM and I came to the conclusion that possibly there were some timing issues causing the instability. According to this post. On stardot someone had managed to piggy back a SRAM on the internal ROM without the issues I was seeing. Anyway this is the front of the PCB from the new version. And this is the back of the PCB where the real work with the wire links and cuts occurs. Im pretty happy with this project now. My...

PXE Grub and All in One Images. So one little advertised feature of grub is grub-mkstandalone. Over the past week I have been playing with grub-mkstandalone to create grub.efi for a new board. We had an issue that the default grub with CentOS 7 performs badly on some EFI firmware when using tftp and it suddenly occured to me that grub-mkstandalone allows you to put file into the grub.efi itself. So for the arm64 server I was working on. The contect of the boot/grub/grub.cfg. This entry was posted in Work.

I blame ‘hrw’ for showing off his Chromebook at Connect, but when I returned to the UK I obtained one. Running chrome itself is of little interest to me, much more interested in using it as a laptop. So first of all I used ChrUbuntu. To get a 12.04 on it. Then I followed hrw’s instructions. How to upgrade to 13.04. I messed it up a couple of times but eventually succeeded. Very nice little device, I hope more of this sort of low power laptop appear to replace the now killed netbook market. March 16, 2013.
