I was looking for instructions for doing that to the cost reduced motherboard but haven’t found any yet. The main problem for me would be making the cable - not my skill set.

Re: Someone's pinched my econet!

I’ve picked up a few boards like that. It seems to be pretty random which chips are fitted, whether they’re soldered or socketed, or whether other blank spaces have empty sockets. Never any resistors etc fitted. Almost as if the factory started making econet-capable boards but changed their minds pa...

Re: All the cheese wedges, in order

From reading old Beebugs and Acorn Users from the period, it would appear that the real reason for delayed release was that Acorn found it rather trickier to get the Tube working properly. Beebug from Sept 1982 lists all three 2Ps, giving provisional production dates of November 1982 for the 6502 an...

Re: All the cheese wedges, in order

There's an article in Beebug Vol 1, Iss 6 (Oct 82) about the Tube. This refers to the 6502, Z80, and a "16 bit NS 16032 based machine", which goes along with what Acorn claimed they would be producing. It would seem there was a common perception that the 16032 was 16-bit, which was why NS renamed it...

Setting up multiple partitions on CF card

I’ve got several IDE solutions (Wizzo, Simtec podule etc) that will let me run multiple partitions on one device. I’ve also just got hold of several IDE to CF adapters, so it would be nice to run a few (currently driveless) machines with 4 partitions on one CF card. If it’s possible, the easiest way...

Re: Acorn Communicators on TV… in 1996

Re: Acorn Communicators on TV… in 1996

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.

Re: Obtain an Amiga

The A500 is nice for basic retro gaming, playing games via a floppies or a GoTek. But the A1200 is a much easier machine to deal with if you're looking to do more than that.

Re: RISC PC Disappearing Memory

At a guess, because the machine is only findng 64Mb, all of which checks out okay? When the RPC was launched, the product literature claimed to take up to 128Mb SIMMs, with the small print to the effect “when this is available”. So it wasn’t ever tested as working with 128Mb during design, because t...

Can the FPU podule not co-exist with the ARM3?

Looks like the support disc may be MIA. I’ll upload when I get chance. As for what can be done with it, disappointingly little in practical terms.
