Thanks for your response Hap,

Version 101-64109 of the CB-emu Sensory Champion is the same as the Sensory Voice. The book is therefore identical.
I just dismantled one of my CSC, the roms of the program are identical to those of CB-emu except that which must correspond to the book: 101-1024A04.
Maybe the first series of the CSC was delivered with the book of the sensory Voice then a new book (modified) appeared.

For the Sensory Elite, if it is the version of travenmude in CB emu, it should therefore work at 5 MHz and not 4 MHz, correct?
