Isolated Word Recognisor

I acquired this from an ex-Acorn employee in the mid-90s. The only thing I've ever managed to find out is that it had its own OSWORD, but I've never come across any documentation or software (or even pictures).

Anyone know anything about it?

Solidisk 256 rehab

Getting on for 20 years ago I picked up a 4MHz Solidisk 256 board from Wakefield, one not-very-careful (okay, downright abusive) previous owner. It powers up fine in 2Mhz mode, never complains about no 4MHz clock, and passes its ram test. Trouble is, it won't enter 4MHz mode, no matter how the speed...

Strange RiscPC floppy fault

Hi, I've been gradually restoring my first RiscPC (Issue 1 board) to fully working status following nasty battery damage. It's almost fully functional following repair of a bad track between IC16 and VIDC (wouldn't start) and replacing C122 (very shaky video). I thought all was fine apart from the b...

More discs rescued from Acorn following Black Thursday.
This time for the ARM. I presume, either from dates within the files or it being specifically mentioned, these are for the ARM Second Processor, ie they're ARM1 versions.

Re: Anyone got Communicator system software? (Basic has 65816 assembler)

Briefcase is 1.70 I think I may have found the reason why it never sold. There's a fundamental design flaw in the case interior, whereby there's about half an inch too little clearance behind the DIN connectors. As a result, you can't plug in a monitor without either detaching the machine from the c...

Re: Anyone got Communicator system software? (Basic has 65816 assembler)

Communicator is 1.00.
I'll try to check the briefcase one tomorrow. Since it was Acorn's warehouse surplus sold some 10 years later, and I suspect the briefcase is a later variant, this may be one of the last ones made.

Despite having used this for a year as my means of dialling into the university's mainframe in the 90s, I had no idea what the button did, which probably gives some idea as to its usefulness. I've just tried it, and it returns you to the Carousel if that's active, otherwise to the Main Menu. Except ...

Re: Arthur for A500 Second Processor

That's my guess, but whilst the Tube ULA could have been removed, it doesn't look as though SK5 was ever fitted. There must have been some other way of hooking it to the Tube, and the podule method does make some sense since the on-board Tube support code for both 2P and full A500 would then be the ...

Re: Arthur for A500 Second Processor

Bear in mind that the A500 and A500 Second Processor (http://chrisacorns.computinghistory.org.uk/8bit_Upgrades/Acorn_A5002ndProcAL.html) are very different beasts. A friend at ARM who had both reckoned that the 2P preceded the full A500, so by the time the A500 was available most of the necessary ha...

I had wondered about the socket, but had somewhat discounted it.

Slightly bending the relevant leg on the 6502 seems t...

Re: Poorly Model B

User VIA is IC69, isn't it? But yeah, it's out.

Removing or swapping S25 has no effect (sorry, forgot to mention that I'd already tried it South).

nRST does indeed go low when I press Break.

Voltage at all 3 points is 4.94V and stable. Presumably this is close enough?
