Re: Worth Taking a Look At

There's an interesting A310 on eBay at the moment that seems to be running some form of development version of RISC OS 3… A couple of the screenshots show it booting with the text below printed over the RISC OS 3 logo screen: Development Pinboard Module (0.51a) - NOT FOR SALE Development Filer Modul...

Re: Acorn ROM/RAM Podule Manager

There’s a ROM used in the Acorn R225 to boot RISCiX remotely I think.

Re: Stardot possibly hacked?

I think it is also quite a common tactic that if hackers get hold of someone's address book or email account that they will just pair address from that on to make the email seem more believable. After all, if Alice knows Bob and Bob Knows Charlie it's quite likely that Alice might also know Charlie,...

Re: Apple goes ARM

Finally as an Acorn fan I remember that Apple partnered with Acorn and VLSI to form the company we know today as ARM, whose processor designs they'll be using in their new laptops and desktops. Actually, I don't think they are using ARM processor designs -- they are just using the AArch64 instructi...

Re: Someone's pinched my econet! (Not Mine Any More!)

Recommendations for any educational titles would be much appreciated.

No chance I expect. As I understand it, Apple's silicon is likely to be AArch64 only, while RISC OS is stuck in AArch32 (32-bit) ARM land.

Bull Electrical were flogging them off, boxed with manuals, for £30 each around 1994/5. As well as cheap night vision and other geeky stuff.

It should be there -- it's certainly in the tar on the website. It should be found in: BeebEmX/BeebEmX/Emulator/BEEmulator.h
