Changes
The 16 bit computer generation peacefully "killed" the 8 bit computers.
Amstrad couldn't see this move and released the Amstrad Plus range which should have been 16 -bit.(Or perhaps it should have another been an hybrid with both a 16-bit CPU and a Z80 to get a 2x8 bit while keeping keep compatibility with the the old range .... , why not ?)
On the other hand, Amstrad was still producing cheap 16 bit PC compatibles with pseudo EGA capacity (16 colours), so in this way it was actually a 16 bit producer.
