I have wanted a CPC 472 for a long time, and on Friday just gone it arrived ;D
I had paid for this in mid December so almost a month of waiting..but it was worth it.
It was very grubby both inside & out and the tape counter reset button appears to have been damaged in the post.
I took it out and attempted to glue it, but after a couple of resets it broke again.
Also some keys were not working, all on a common line with the keyboard switch matrix.
I proved the issue to the membrane and swapped the membrane with another and now the 472 is fully operational other than
the tape counter reset button (the tape counter stills works).
It took a bit of cleaning, but it now looks quite OK.
If anybody has a spare tape counter and or a spare 464 keyboard membrane then I'd be interested ;)
Cheers,
Shane
Fantastic! You're building quite a collection for yourself!
A beauty! :)
That add-on board seems an unnecessarily complex way of adding 8KB of inaccessable ram.
Well... without the board the computer won't boot anyway, so it's not a bad way to convince the authorities that it has really more ram and won't work without it.
The last three characters of the chip's serial number are "HAK". What more needs to be said? :laugh:
Hahaha @ db6128 :)
Actually I reckon the idea was a stroke of genius and a really simple idea and implementation.
I think the story and history behind it is cool though, and for anyone that has not read about it, the wiki has an excellent entry for it.

Nice find !
Just a simple question: does it display "72Ko Ram" at boot ?
No, because you can only access 64 KB. The other 8 KB are wasted, therefore I never liked that 472. What a pity.
Although I really like the Spanish keyboard 472 (the one I managed to get hold of) for the true authentic Spanish look :D I suppose the one to have would be the early 472 with the English keyboard and the 664 ROM fitted, giving you BASIC 1.1 instead of the usual BASIC 1.0 of the 464.
From what I understand both appear to be reasonably rare though.
I think back in it's day a person who bought one of these may have been disappointed to find you could not access the extra 8k.
But as I mentioned previously, for me the history behind the 472 is the cool thing, these days not being able to acces that 8k is not really an issue (although it would have been nice) :) .

Shane

Remember ... that happened to me first with the 6128 too, every kind of software was for 64 KB CPCs, except CP/M Plus. Took years until things got a bit better.

I want to know the same as Kris. What does it show on boot?
The ROM in the 472's was totally un-modified, so just the standard boot screen.
For the early 472 with English keyboard, it had the 40022 ROM (same boot screen as the English CPC 664).

The Spanish keyboard version had the standard 40037 ROM (Spanish) and displayed the normal 464 screen with (s1) to indicate the Spanish ROM.

That's correct (I did investigate one of them once at the XzentriX meeting).
I was thinking... why not burn a new ROM and change the message to 72kb, and put in an internal Multiface 2 - then you will really have a 472
