It's all in the flashfloppy wiki: https://github.com/keirf/FlashFloppy/wiki

Hardware mods, how to flash, etc, etc...

I have the kit to archive/recover it and I'm in Manchester - don't touch it, wait until we're allowed out again, and I'm happy to have a go at recovery?

Pause in "Wanted" posts

Hi all,
Just whilst we're all restricted we're putting a pause in on selling/wanted requests to stop people feeling obliged to make unnecessary trips to the post office that might put them or others at risk, as well as additional strain on services. Hopefully it won't last too long :)

Re: A3000 work

You'll need to give them a quick dunk/scrub then rinse. There's no sense in using IPA on a battery leak, it just moves the stuff around, doesn't actually neutralise anything or clean it up. IPA is good for grease/resin removal, absolutely rubbish for mineral salts that are soluble in water :)

Re: A3000 work

Cut battery out.
100% distilled vinegar, no need to dilute. Give it a rub with a brush. Bin the brush. There might be cadmium knocking about, it's not very nice.

Rinse well with water, distilled if your water isn't soft.

Let dry, survey damage.

No need for IPA or anything.

Re: Today I overclocked my A3010

Nice to see others running the ARM250 at these speeds :D Have you put a heatsink on the RAM? When I first did this mod I left the machine running SF3000 for hours on end and the RAM would be the one to get too hot. On the 2 machines I did this overclock on 25mhz worked on both with no issues. This ...

Have you put a heat sink on the ARM? It may need it at that clock rate. It was getting above 60C at 72MHz.
This does sound unusual, I've not heard of others getting this hot.

Try a clean boot (i.e. shift-held at switch on so uniboot isn't loaded).

Re: Electron loading volume

I was never aware of the volume setting having any impact on recording on any of the tape decks I ever had?

In so far as typical, it entirely depends on the deck as Colin said :) - the volume numbers are entirely arbitrary (apart from 11 on Marshall Amps).

As in running the disk image? I'd still want to try it without ADFFS. Even if you're not autobooting it does do some bits and bobs iirc... Including some stuff around trapping screen modes.

Mine's set to 350. :) You're removing a dead chip, so you don't need to worry about saving it. The easiest way to do this is to use side cutters, and cut each leg close to the body of the chip, then lift that away. After that you can remove each pin by heating up and whisking out from the top side w...
