Hi Michael,

interesting news
Mini, Junior and Graduate are nown as clones (all have 2 Levels with a mechanical switch).
CP3000 has 8 Levels and CP4000 12 Levels by mechanical switches - how did they do it with the same ROM? Are the switches fakes (all result in only 2 positions)?
If not, they must still have planned the later versions with more levels - and then it should be possible to extend the older items with more levels by changing the switches...

Regards
Achim
