6 MHz CPC - CPCWiki

It's more of a "Look what you can do" on that page, doesn't show in detail, needs an in depth guide on 'how to do it'.

TFM:
The Wiki article tells all details needed, just exchange the crystal or add a 2nd one.  :)

PulkoMandy:
Yes it's really that simple:
1) Remove 16 MHz crystal from motherboard
2) Insert 24MHz crystal
3) Profit!!!


It is possible to add a switch to select between the two crystals, you need a switch with two lanes and two positions (DSDT). Try to keep the wires short in that case.


Some warnings:
- You need to adjust CRTC values manually. There is no adjusted system ROM available (as far as I know?)
- Your floppy disks will be completely unreadable by any other machine. If you could reach 8MHz, they would be HD disks, but the electronics in the CPC won't work at such high speed. This creates a challenge in transferring data. Maybe tape can be used with the correct "speed write" settings?
