Re: IBM OS/2

I'd be interested, just to have a play with, but I don't have anything old enough to run it on...unless it'll run on an RiscPC with a PC card. Probably not, the RiscPC PC card was a bit of a bodge and didn't implement the full PC spec. As such Windows 3.1 and 95 ran, NT didn't and you needed a very...

Correct. It's a very shrunk down gotek.

Would it be possible for someone to scan this?
Realistically no, non-destructively scanning a book of a few hundred pages isn't likely to be something that someone would be willing to commit too. Hint it'd probably take a few hours at least.

Re: Is there a way to get RiscOS 3.11 chips for a A3010 cheaply?

Is this a repair or replacement of 3.10?

If a replacement, don't bother, the differences are so minor you won't notice, and are softloadable.

You’re sure using peroxide will not adversely affect the plastics? I’d be worried it might make stuff weaker/more brittle Retrobrite = peroxide mixed with a gel to make it stick on better. The same trick of dunking plastics in a peroxide bath and turning on a UV lamp is also a good way to recover y...
