CPC four times faster...

[McArti0]

The SuperZ80 expansion card, disabling the internal Z80, writing speed to internal RAM 20kB per frame 1us per byte.

SuperCPU could have a larger than I design (one address, one byte =24 bit) write buffer to CPC RAM. Each write to the buffer is fast. Wait states appear when the buffer does not have time to empty. When buffer is full during nCPU is Hi, SuperZ80 can execute several non-write instructions or wait for write byte to buffer.
I was also thinking about a 9-bit clone ROM, which it would download while executing the code and write the 9th bit that this byte is already cached inside.

regarding video, FDC and probably more.

VGA monitor welcomes this with open arms.

Does Gotek also have a problem?

The Gotek would have to listen to a 1,5times faster FDC. All sectors will have a 1,5times higher density, which was the problem of a 6MHz CPC. Because of this you werent' able to exchange discs between a 4 and a 6MHz CPC. A 6MHz CPC could save about 6,7KB/track instead of 4,5KB.

and all disk drives are equally fast? 3,5" too?

BTW: I have a CPC6128 running at 6 MHz stable. Just replaced the 16 MHz crystal by a 24 MHz one.

Yes, your old story.
But "stable" is a very relative description.
It is useless/not compatible regarding video, FDC and probably more.
Unfortunately I forgot it, but what was the CPC meeting, where you presented this 6MHz machine to the public?

Yeah, and now that's your old story too. Like usually you want to tell people what's 'useless' for them. But what you mean is just, that something is useless for you / SymbOS. Try to be a bit less Narciss.   Come on, allow us to live our CPC hobby our way! 

BTW: IIRC the meeting was either one of the CPC-Only meetings or some XzentriX, but it's something like 18-21 years ago. And the CPC still runs like a charm. I love the enhances = horizontally squeezed screen and also to be able to put 50% more data on an disc. 

Anything else... It's 3 the morning. Read you later the day...

Have you ever tried to speed up the motor that spins a floppy disk? Is this controlled by the device software?

and also to be able to put 50% more data on an disc.

Ho wdo you exchange data with this CPC? Are other expansions compatible and can be used, like the M4 or Symbiface?
