 ## Main features
 
-- LTC6903 chip for frequency control (1kHz to 68Mhz)
+- Follow the [MOM1_SPS1](https://github.com/JonathSpirit/GComputer_standard) standard.
+
+- A controllable frequency of 50Mhz divisible by multiples of two up to a division of 65536.
+
+- The same separate controllable frequency divisible by multiples of two for peripherals.
 
-- 2 memory slot with address extension connector
+- 4 peripherals slot (that follow standard [PP1](https://github.com/JonathSpirit/GComputer_standard)).
 
-- Source switch between the 2 memory slot
+- 2 [MM1](https://github.com/JonathSpirit/GComputer_standard) memory slot with address extension.
 
-- 4 peripherals slot
+- Readable code source switching from the 2 memory slot.
+
+- Redirection of the writing buses.
+
+- Accessible debug pins.
 
-- Write bus redirection
