    My Bifrost has it's new software chip installed now



    It's all working fine, but I've noticed that I've left the HDD LED a little bent - I'll correct it the next time I do something to it

    I decided that I needed to do something about this mess of cable for the floppy extension that connects up the HxC:



    After a bit of happy hacking with a new IDC34 (so that I didn't confuse wires like I have in the past with this extension), it's now much tidier:



    I straightened up the LED for the HDD too - still seem to have minor issues with stability when everything is running together, so possibly my PSU isn't able to cope with the load. Will have to see about borrowing something to test before launching off into some sort of replacement/upgrade.

    Nopes - it's not power that's the issue, it's our old friend heat again. Took the A1200 down to the server room where it has good A/C and it ran fine with anything I threw at it.

    Going to look at improving the cooling of the Indivision and Bvision by adding active fans (removing the two extracting fans from the lid) and I've a new heatsink in progress for the BPPC to try to improve the temps of the PPC. I'm going to put two larger extracting fans into the lid and then test again

    I've reworked the inside of the case lid again, removing the two small fans and having fitted provision for a larger high CFM 30mm fan instead:



    I doubt my A1200 will be quiet anymore with the speed of the new fan when it turns up, but at least it'll stay cool. I'm going to place a heatsink on Lisa too, as she gets really hot during use - I suspect most of that is the plate on the rear of the keyboard heating up because of the shortage of air extraction, but it'll help a little. Waiting to hear on a new heatsink for my BPPC too - I've a lump of copper for it to be made from, but trying to figure out how to get it done without upsetting anyone at work lol
